ANSWER
Arteries - Red
Veins - Blue
Question 2
What are the two main components of the cardiovascular system and their functions?
ANSWER
The heart (pumps blood) and blood vessels (transport blood).
Question 3

,Question 9
What are the functions of the atria
ANSWER
Atria receive blood; Right atrium gets blood from body, right ventricle to lungs
Question 10
What are the functions of the ventricles
ANSWER
Ventricles pump it out, left atrium from lungs, left ventricle to body.
Question 11
What are the four heart valves and their locations?
ANSWER
Tricuspid (right AV), pulmonary semilunar, mitral/bicuspid (left AV), aortic semilunar.
Question 12
How does blood flow through the heart?
ANSWER
It's a continuous path through the chambers and valves; can be traced from any starting
point.
Question 13
What separates the right and left atria?
3
, ANSWER
The interatrial septum.
Question 14
Which vessels return blood to the right atrium?
ANSWER
The superior vena cava, inferior vena cava, and coronary sinus.
Question 15
What are chordae tendineae and papillary muscles?
ANSWER
Chordae tendineae anchor AV valve flaps; papillary muscles contract to prevent valve
prolapse.
Question 16
What arteries supply blood to the heart muscle?
ANSWER
The coronary arteries.
Question 17
Define systole and diastole.
ANSWER
Systole is contraction; diastole is relaxation of the heart chambers.
