"Knees" Natural Recordings by Native Speakers
The word "knees" refers to the joints that connect the femur (thigh bone) to the tibia (shin bone) in the human body, allowing for bending, straightening, and flexion. It can also refer to the area around these joints.
The word "kneecaps" refers to the bony structures that cover and protect the knee joint. They are also known as patellae, and are located at the front of the knee. Kneecaps play an important role in knee movement, allowing the knee to flex and extend properly.
