Practice Test 4
Why are the walls of the veins so thin? __________________________________________________________
_________________________________________________________________________________________
What two muscles contract during ventilation? ___________________________________________________
_________________________________________________________________________________________
What are the 3 stages of blood flow in the veins?
Name 3 valves involved in blood flow in the heart.
Heart tissue is called
pericardium
myocardium
septum
vena cava
The septum and the chordae tendineae are part of the heart’s internal or external anatomy? ________________
_________________________________________________________________________________________
What is the function of the septum? ____________________________________________________________
_________________________________________________________________________________________
The function of the chordae tendineae is to:
prevent valves from averting blood
to protect the heart tissue
to lower pressure in the thoracic cavity
to allow blood to be forced back to the heart during contractions
Coronary arteries on the heart’s surface
take waste and CO2 away from heart tissue
deliver O2 and nutrients to heart tissue
stimulate contractions
conduct electrical impulses
What is the difference between LUB and DUB? __________________________________________________
