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.

The lymph nodes of the axillary region receive lymph mainly from the upper limb and mammary gland.

Explanation
Circulation is the movement or flow of something, especially blood or air, through a circuit or a specific course.
Circulation supplies oxygen and nutrients to and removes wastes from tissues. This is essential for the survival and functioning of cells and organs.
Choice A is wrong because circulation does not inflate the lungs.
The lungs are inflated by the pressure difference between the air inside and outside the chest cavity.
Choice C is wrong because circulation does not deliver waste to tissues.
Circulation removes wastes from tissues and delivers them to the excretory organs such as the kidneys and the lungs.
Choice D is wrong because circulation does not deliver carbon dioxide to tissues and removes excess oxygen.
Circulation does the opposite: it delivers oxygen to tissues and removes carbon dioxide.
Carbon dioxide is a waste product of cellular respiration that needs to be eliminated from the body.
