Answer to Question 1

A, B, D
Feedback:
The pressure in the cardiovascular system is determined by three elements: heart rate, stroke volume, or the amount of blood that is pumped out of the ventricle with each heartbeat (primarily determined by the volume of blood in the system), and total peripheral resistance, or the resistance of the muscular arteries to the blood being pumped through. The preload and the pulse pressure are not factors that regulate pressure in the cardiovascular system.

Answer to Question 2

A
Feedback:
The lung tissue receives its blood supply from the bronchial artery, which branches directly off the aorta. The alveoli receive unoxygenated blood from the right ventricle via the pulmonary artery. The delivery of this blood to the alveoli is referred to as pulmonary perfusion. Oxygenation is the process where unoxygenated blood receives oxygen in the lungs. Expiration is the act of exhaling to rid the body of excess carbon dioxide. Inhalation is the act of inhaling or taking in air to replace oxygen from the air.
