a. true
b. false

The answer to the statement: At rest, most of the body´s blood supply resides in the pulmonary loop, would be, B: False.

Explanation:

The circulatory system never stops working. Pumping of blood, transportation of oxygen, nutrients and water to and from tissues is a process that does not end, even during sleep. The only moment when this process does not happen, is in death. However, a good question is, where does the blood go, or stay, when the body is not active, like for example, during sleep. And the answer is that most of it will rest on the systemic veins and venules and will slowly circulate back to the heart, but at a much lower rate than when the body activates itself. However, what is not true is that blood will reside mostly in the pulmonary loop, because this loop does not have the capacity to store that much blood.

the ileocecal valve (also called bauhin valve), which limits the rate of food passage into the cecum and may prevent material from returning to the small intestine.
