What is the subclavian steal syndrome?

A condition where an artery takes or “steals” blood that’s supposed to go to your brain. Instead, that blood goes to your arm. This happens because of a narrowing or blockage in your subclavian artery (usually the left one) that normally sends blood to your arm on that side.

A patient with deep vein thrombosis (DVT) complains of leg pain and swelling. Which vein is most commonly affected in DVT cases?

Femoral Veins

What is the unique arrangement of veins that deliver 80% of the blood flow to the liver and delivers blood from all digestive organs to the liver? 

Hepatic Portal System (Part of Hepatic Circulation)

What is a venous hum and where can it be heard?

A benign auscultatory phenomenon caused by the normal flow of blood through the jugular veins.  The sound is heard in the upper chest near the clavicle.

b) “Capillaries allow for nutrient exchange.”

c) “Capillaries carry oxygenated blood.”

d) “Capillaries are larger than veins.”
