Question

Posterior to kidneys, follow blood flow from the dorsal aorta into the rear legs, and back to the heart. Name the vessels in order as you go.

Expert Solution

Step 1

Systemic circulation is one of the two types of blood circuits found in the human body's circulatory system. In this circulation, oxygenated blood from the heart's left ventricle is distributed to all body parts, and the deoxygenated blood from the tissues and organs is transported back to the heart for purification.

Step 2

Branches of the aorta carry out the distribution of oxygenated blood, and the vena cava branches collect deoxygenated blood. The circulation in the rear legs involves the branches of the abdominal aorta and iliac veins in the following order:

The abdominal aorta descends into the iliac artery; the external iliac artery descends in the lower limbs and is now called the femoral arteries.
The femoral arteries and their branches supply blood to the thigh region; on descending, it forms the popliteal artery, which supplies blood to the knee joint.
The popliteal artery descends branches into an anterior and posterior tibial artery and supplies blood to the limb's calf and shin regions.
The tibial arteries then branch to form the dorsalis pedis artery and malleolus artery, which supplies blood to the feet area.
The small saphenous vein and veins of the dorsal venous arch collect blood from the ankle and foot region. The posterior and anterior veins collect blood from the calf and shine region; together, these veins empty the collected blood into the popliteal vein.
The popliteal vein further collects blood from the knee regions and pass it into the femoral vein located in the thighs.
The femoral vein, along with the great saphenous vein, returns deoxygenated blood to the external iliac vein.
The external iliac vein returns blood to the heart via the inferior vena cava.
