CVS 204- Exam 1 QUESTIONS AND ANSWERS 2026
UPDATE
pectinate muscles - anchors the valves in the ventricles
trabeculae carneae - the waffle like muscular ridges in the ventricles
What does trabeculae carneae do? - prevents stagnation of blood during low Cardiac output
Where are the pectinate muscles located? - right atrium
Where are trabeculae carnae NOT located? - in the outflow tracts
The right side of the heart receives: - deoxygenated blood
the left side of the heart receives: - oxygenated blood
pulmonic circulation - right side; from body to lungs
systemic circulation - circulation that supplies blood to all the body except to the lungs
, how much fluid is in the pericardial sac ? - 5-10 mL
SA node is the - pacemaker of the heart
The SA node is located: - upper RA at the junction of the SVC
Firing rate of the SA: - 60-100 bpm
firing rate of the AV node: - 40-60 bpm
firing rate of Purkinje Fibers - 20-40 bpm
Diastole - filling phase (atrioventricular)
-blood filling into the ventricles
-AML and PML are seen
systole - contracting phase
-atrioventricular valves are closed and blood is filling into the lungs and body
-RCC and NCC are seen
what is the function of the pericardium ? - Protect against friction and permit free movement of
the heart during contraction
What is the rudimentary valve of the CS ? - Thesbian
what is the rudimentary valve of the IVC? - Eustachian
