Where does gas exchange occur in the lungs?
Alveoli

The cells in the respiratory tract secrete mucus and other cells have a structure called _____________, which beat back and forth, carrying the mucus and trapped particles up and into the pharynx where it can be swallowed.
Cilia

A sudden drop in mean arteriole pressure from a loss of blood will result in all of the following except a.An increase in heart rate. b.A lower frequency of action potential from baroreceptors to the CNS. c.A decrease in total peripheral resistance because of va sodilation of thearterioles. d.An increase in end diastolic volume followed by an increase in stroke volume

Name the two major types of Alveolar cells. What are their functions?
Type I cells are where gas exchange occurs, whereas Type II cells produce/secrete surfactant.
500
What are two ways the body can control arterial blood pressure? How do the sympathetic and parasympathetic nervous systems affect each of these two factors?
Possible answers: 1. Heart rate Sympathetic → increase HRParasympathetic → decrease HR 2. Total peripheral resistance (TPR) Sympathetic → increase TPR 3. Stroke volume (SV) Sympathetic → increase SV
