Vett 134, The Heart - Exam Questions and Answers Latest Update 2025-2026 Already Passed
Which type of blood vessel carries blood away from the heart? - Answers Arteries
Which type of blood vessel carries blood toward the heart? - Answers Veins
What are the two parts of the cardiovascular system? - Answers Pulmonary circulation and systemic
circulation
List three structures found in the mediastinum: - Answers heart, blood vessels, trachea, esophagus,
lymph nodes and nerves
Which is located more caudally in the standing pig, the apex or the base of the heart? - Answers Apex
what is the difference between the endocardium and the pericarduim? - Answers endocardium is the
membrane that lies on the internal surface of the myocardium, pericardium is the sac that surrounds
the heart.
which sits closer the the base of the heart, the left atrium or the right ventricle? - Answers left atrium
what is the name of the structure that is a continuation of the myocardium that forms a wall between
the two atria? the two ventricles - Answers interarterial septum, interventricular septum
why is the wall of the right ventricle thinner than the wall of the left ventricle? - Answers because the
blood pumping from the right ventricle only has to go to the lungs while the blood pumping from the left
ventricle is pumped throughout the body.
what is another name for each of the valves: Right AV valve, semilunar valve in the right ventricle, left
AV valve and semilunar valve in the left ventricle. - Answers Tricuspid valve because it has 3 flaps,
Pulmonary valve because blood flows trough it into pulmonary circulation, Bicuspid valve or mitral valve
because it has two flaps, aortic valve because blood flows through it into systemic circulation.
what is the function of the Chordae Tendonae? - Answers Chordae Tendonae are collagen fibers that are
attached to the edge of each cusp of the Tri/Bicuspid valves and to the papillary muscles in the wall of
their ventricle. Prevents the valve from opening backwards into their atrium.
List in order the structures an erythrocyte will pass through to move in a complete circuit from the left
ventricle to the left ventricle. - Answers left ventricle, aortic valve, aorta, arterioles, capillaries, venues,
veins, vena cava, right atrium, tricuspid valve, right ventricle, pulmonary valve, lungs, pulmonary vein,
left atrium, mitral valve, left ventricle.
what is the pacemaker of the heart and where is it located? - Answers Sinoatrial node (SA Node), located
in the wall of the right atrium.
list the four conductors that make up the rapid conduction system for an impulse created by the hearts
pacemaker. - Answers SA Node, AV node, bundle of His, purkinje fiber system
