Where is the location of the popliteal artery within the body?
Around the thymus.
Around the liver, spleen, and upper gastrointestinal tract.
Behind the knee.
The colon and rectum.
The Correct Answer is C
The popliteal artery is a continuation of the femoral artery that runs through the back of the leg and the knee.
It is located in the popliteal fossa, a hollow space behind the knee. The popliteal pulse can be felt behind the knee.
Choice A is wrong because the thymus is a gland in the chest, not in the leg.
Choice B is wrong because the liver, spleen, and upper gastrointestinal tract are organs in the abdomen, not in the leg.
Choice D is wrong because the colon and rectum are parts of the large intestine, not the leg.
