APHY 102-Ch 15-Cardiovascular (Heart & Blood
Vessels) midterm exam / Revised Questions and
Answers / Guaranteed Pass
At any given moment, where can blood be found in the body? - The veins



Describe an EKG. What is occurring within the heart during each part of the EKG? - A test that
measures the electrical signals that control heart rhythm.



With each beat, an electrical impulse (or "wave") travels through the heart. This wave causes the muscle
to squeeze and pump blood from the heart.



Describe the layers of the heart and pericardium. - Epicardium: The outermost layer of the heart
wall and is just another name for the visceral layer of the pericardium.



Myocardium: The muscular middle layer of the heart wall that contains the cardiac muscle tissue.



Endocardium: Simple squamous endothelium layer that lines the inside of the heart.



Describe the pathway of blood into, through, and out of the heart. - Arteries: Carry blood away
from the ventricles of the heart.



Arterioles: Receive blood from the arteries, and carry it to the capillaries.



Capillaries: Sites of exchange of substances between the blood and the body cells.



Venules: Receive blood from the capillaries, and conduct it to veins.



Veins: Receive blood from venules, and carry it back to the atria of the heart.
