Final answer:
No, nothing exits the skin in an AV shunt as it is simply a connection between an artery and a vein used in medical procedures.
Step-by-step explanation:
The question is asking whether anything exits the skin in an arteriovenous (AV) shunt. The correct answer is No, nothing exits the skin in an AV shunt. An AV shunt is a small, surgically created connection between an artery and a vein. This is used in medical procedures like dialysis, where blood is taken out of the body, filtered, and then returned. The process involves blood circulation through the shunt but does not involve any substances exiting through the skin.
