Which main tissue type of the circulatory system regulates airflow to alveoli?

Question

Quizplus · Accepted Answer

The main tissue type that regulates airflow to alveoli is muscle tissue. Specifically, smooth muscle fibers located in the walls of the bronchioles can contract or relax to change the diameter of these airways, thereby regulating the flow of air into and out of the alveoli. The circulatory system primarily consists of vascular tissue, which includes arteries, veins, and capillaries that transport blood throughout the body. Connective tissue provides support and structure, while nervous tissue enables communication and coordination throughout the body. Nonvascular tissue does not have blood vessels and is thus not involved in the circulatory system.
