Question

what does the heart do? select all that apply. it provides protection for some of the bodys soft organs. it produces insulin, a hormone that helps regulate the bodys glucose level. it pumps oxygen - poor blood to the lungs and oxygen - rich blood to other body organs. it detects changes to the bodys environment, such as temperature. it is a muscle that helps the lungs expand and contract.

Explanation:

The heart is a muscular organ that functions as a pump in the circulatory system. Its main role is to circulate blood throughout the body. It pumps oxygen - poor blood to the lungs for oxygenation and oxygen - rich blood to other body organs to supply them with oxygen and nutrients. It does not provide protection for soft organs (bones and other structures do that), does not produce insulin (the pancreas does), does not detect environmental changes like temperature (sensory receptors do), and is not involved in lung expansion and contraction (respiratory muscles like the diaphragm do).

Answer:

C. It pumps oxygen - poor blood to the lungs and oxygen - rich blood to other body organs.
