Words Starting With "H"

Our pre-recorded sounds are fast, clear, and natural, spoken by native speakers.

Hemitropy

speak

Hemitropy refers to a hypothetical property proposed by physicist Christopher Dewdney, which describes the ability of a system to be influenced by its own history, rather than just its current state. In other words, hemitropy is the ability of a system to "remember" its past states and be affected by them, even when the current state is different. This concept is still purely theoretical and has not been directly observed in natural systems, but it has been explored in the context of quantum mechanics and the study of complex systems.

Hemivertebra

speak

A hemivertebra is a type of congenital deformity of the spine, where one half of a vertebra fails to develop normally, resulting in an abnormal curvature of the spine. It is often found in combination with other spinal abnormalities, and can vary in severity from mild to severe. Hemivertebrae can cause a range of symptoms, including back pain, numbness or tingling in the legs, and decreased mobility. Treatment options for hemivertebrae include bracing, physical therapy, and in some cases, surgery.

Hemizygous

speak

Hemizygous refers to an individual or cell that has only one copy of a particular gene or genetic sequence, rather than the normal two copies. This can occur when an individual has a mutation or deletion of one of the two copies of the gene, leaving a single copy remaining.

Hemline

speak

The hemline refers to the lower edge of a skirt, dress, or other article of clothing that is sewn into the garment. It is typically where the garment meets the wearer's leg.

Hemlines

speak

The word "hemlines" refers to the lower edge of a garment, typically a skirt or dress, where it is finished with a hem or folded edge.

Hemlock

speak

Hemlock is a type of poisonous plant, particularly the botanical species Conium maculatum. It contains toxic alkaloids that can be fatal if ingested. In medicine and literature, hemlock is often associated with the poison used by the ancient Greeks to execute Socrates.

Hemmed

speak

Hemmed means having a finished edge at the bottom, typically with a serged or folded edge, to prevent fraying. It can also refer to something that is restricted or constrained, such as being hemmed in by circumstances.

Hemming

speak

To hem is to shorten the length of the edge of a garment, such as a skirt or pants, by folding and sewing a new edge to prevent fraying or to create a specific length. Hemming can be done by hand or by machine, and it is a common alteration made to clothing items to make them fit better or to update their style.

Hemocatheresis

speak

Hemocatheresis is a medical term that refers to a medical procedure in which blood is removed from a patient's circulatory system and processed to remove or extract substances or cells of interest. The processed blood is then returned to the patient. Hemocatheresis is used to treat various conditions, such as removing unwanted substances, toxins, or microorganisms from the blood, or to transfer specific substances or cells from one patient to another. It is also used in blood transfusions, hemodialysis, and other medical procedures.

Hemoccult

speak

Hemoccult is a noun. It refers to a medical test that is used to detect small amounts of blood in the stool or feces. The test is typically used to screen for gastrointestinal tract cancers, such as colon cancer, and to monitor the progress of cancer treatment.

Hemocele

speak

Hemocele refers to a type of abdominal tumor filled with blood that is characterized by the accumulation of blood in the cavity of the abdominal wall. It is a rare condition that typically occurs in infants and young children, usually as a result of a congenital anomaly or injury. Hemoceles can cause symptoms such as abdominal distension, pain, and vomiting, and may require surgical intervention for treatment.

Hemochorial

speak

Hemochorial refers to a type of placentation, where the chorion, the outermost fetal membrane, is in direct contact with the maternal blood in the placenta, allowing for efficient exchange of oxygen, nutrients, and waste products between the mother and the fetus. This type of placentation is typically found in primates, including humans and monkeys.

Hemochromatosis

speak

Hemochromatosis is a genetic disorder that affects the body's ability to absorb and process iron. It is a condition in which the genotype for hemochromatosis is present, causing an excessive accumulation of iron in the body. This can lead to iron overload, which can cause harm to the body over time.

Hemochrome

speak

Hemochrome is a type of pigment that is derived from the combination of iron and porphyrin, a type of organic compound. It is often found in the blood and other bodily tissues of animals, where it plays a crucial role in the transport of oxygen. Hemochrome is responsible for the red color of blood and is also present in other bodily fluids, such as hemoglobin, myoglobin, and cytochromes.

Hemochromogen

speak

Hemochromogen is a term used in medicine to describe a group of brown or greenish pigments that are produced in the body as a result of iron overload. These pigments are formed when excess iron is stored in tissues, such as the liver, pancreas, and joints, causing them to lose their normal appearance and function.

Hemochromometer

speak

A hemochromometer is a device used in blood chemistry tests to measure the concentration of hemoglobin in blood. It does this by measuring the light absorption by the hemoglobin, which is a protein in red blood cells that carries oxygen. By comparing the amount of light absorbed to a standard, the hemochromometer can give a accurate reading of the hemoglobin level. This test is often used to diagnose and monitor conditions such as anemia, polycythemia, and other blood disorders.

Hemocoel

speak

A hemocoel is a cavity or space within the body of an invertebrate animal, such as an insect, arachnid, or mollusk, that contains fluid and surrounds the internal organs. It is essentially a liquid-filled cavity that provides support and protection to the internal organs, allowing for movement and flexibility. The hemocoel is often compared to the blood-filled cavity in vertebrates, known as the pericardial cavity, although the two are distinct and serve different purposes.

Hemocompatibility

speak

Hemocompatibility refers to the ability of a material or device to interact with blood, platelets, and immune cells without triggering harmful physiological responses, such as blood clotting, inflammation, or complement activation. In other words, it is the compatibility of a material or device with the body's blood and immune systems, ensuring that it does not cause adverse reactions or perpetuate diseases.

Hemoconcentration

speak

Hemoconcentration is a medical term that refers to the increase in concentration of red blood cells and other blood components in the blood due to the loss of plasma and/or interstitial fluid. This can occur as a result of various factors such as dehydration, bleeding, or excessive sweating. As the amount of plasma and interstitial fluid decreases, the concentration of red blood cells, white blood cells, platelets, and other blood components increases. Hemoconcentration can cause a range of symptoms, including headaches, dizziness, and decreased blood pressure.

Hemocratic

speak

There is no word "hemocratic". I think you might be referring to the word "democratic". <br><br>Democratic refers to a system of government in which power is held by the people or their elected representatives, rather than by a single ruler or group. A democratic country usually has free and fair elections, where citizens can vote for their leaders, and laws are made with the consent of the people.

Hemoculture

speak

A hemoculture is a laboratory test that involves collecting a small sample of blood, usually from a vein or an artery, and culturing it on a medium that supports the growth of microorganisms. This test is used to diagnose bloodstream infections, such as sepsis, bacteremia, or endocarditis, by detecting the presence of bacterial or fungal pathogens in the blood.

Hemocultures

speak

Hemocultures are a type of laboratory test used in medicine to detect bacteria or other microorganisms in blood. The test involves collecting a blood sample and then incubating it in a nutrient-rich medium that encourages the growth of any microorganisms present. If microorganisms are present, they will multiply and produce characteristic colony morphology, which can be observed by a laboratory technician. Hemocultures are commonly used to diagnose and monitor bloodstream infections such as sepsis, bacteremia, and endocarditis.

Hemocyanin

speak

Hemocyanin is a copper-containing protein found in the blood of mollusks, such as snails and clams, and in some arthropods, such as crabs and lobsters. It plays a role in transporting oxygen and is involved in the process of oxygen transport and delivery to the tissues.

Hemocyanins

speak

Hemocyanins are a group of copper-containing proteins that function as oxygen carriers in the blood of some invertebrates, such as mollusks and crustaceans. They are similar to hemoglobin in vertebrates, but instead of using iron, they use copper to bind to oxygen. Hemocyanins are responsible for transporting oxygen from the gills to the body tissues of these animals, and they also play a role in immune responses and other physiological processes.

Hemocyte

speak

Hemocyte is a type of blood cell found in invertebrates, such as insects, crustaceans, and mollusks. It is a type of phagocyte, which means it can engulf and digest foreign particles, bacteria, and other cellular debris. Hemocytes play a crucial role in the immune system of invertebrates, helping to defend against infection and disease.

Hemocytes

speak

Hemocytes are a type of blood cell that plays a crucial role in the immune system of insects, crustaceans, and mollusks. They are responsible for engulfing and digesting foreign particles, bacteria, and dead cells, thereby helping to defend the organism against infection and disease. Hemocytes can also participate in wound repair by producing collagen and other substances that help to heal damaged tissue. In addition, some hemocytes may be involved in melanization, a process that causes the formation of melanin, a pigment that protects against UV radiation.

Hemocytoblast

speak

A hemocytoblast is a type of stem cell found in the bone marrow that has the ability to develop into different types of blood cells, including red blood cells, white blood cells, and platelets.

Hemocytoblasts

speak

Hemocytoblasts are the primitive cells in the bone marrow that give rise to all types of blood cells, including red blood cells, white blood cells, and platelets. They are the precursors of the hematopoietic system and are the source of new blood cell production.

Hemocytology

speak

Hemocytology is the branch of medicine that deals with the study of the microscopic examination of the blood and its components, including cells and cell fragments.

Hemocytolysis

speak

Hemocytolysis is a medical term that refers to the destruction or breakdown of red blood cells, particularly excessive destruction of them. It is often caused by certain infections, autoimmune disorders, or cancer treatments, leading to anemia and low red blood cell count.

Hemocytometer

speak

A hemocytometer is a counting chamber used in biology to count the number of cells in a given sample of fluid, such as blood or a tissue culture medium. It consists of a flat plate with a series of small squares or grids etched into its surface. The plate is covered with a thin layer of the sample, and then viewed under a microscope to count the number of cells that fall within each square or grid. The hemocytometer is commonly used in medical settings to determine the concentration of white blood cells in blood, which is an important diagnostic tool for diagnosing and monitoring certain medical conditions.

Hemocytosis

speak

Hemocytosis refers to an abnormal increase in the number of red or white blood cells in the blood.

Hemodialator

speak

A hemodialyzer is a medical device used to remove waste products from the blood in patients with kidney failure. It is used in patients who require dialysis, a process that mimics the function of the kidneys to filter waste and excess fluids from the blood.

Hemodialysate

speak

Hemodialysate refers to a liquid solution used to remove waste products and excess fluids from the blood during hemodialysis, a type of renal replacement therapy. It typically contains a combination of electrolytes, such as potassium, calcium, and magnesium, as well as other substances designed to help restore the balance of chemicals in the blood.

Hemodialysis

speak

Hemodialysis is a medical treatment that filters and purifies the blood when the kidneys are no longer able to do so. It is a type of dialysis that uses a machine to remove waste products, such as urea, and excess fluids from the blood. The machine uses a semi-permeable membrane, a dialysate solution, and the patient's blood to remove the waste products and excess fluids, and return the cleaned blood to the body. Hemodialysis is often used as a treatment for end-stage renal disease (ESRD) and is usually performed three times a week, with each session lasting several hours.

Hemodialyze

speak

To undergo hemodialysis is a medical treatment for people with kidney failure. Hemodialysis is a process in which a machine filters the patient's blood to remove waste products, excess fluids, and electrolytes. This treatment allows waste products to be removed from the blood, helping to correct imbalances and regulate the patient's overall health. It is often used as a life-sustaining treatment for individuals with Stage 5 Chronic Kidney Disease or those who experience acute kidney failure.
