Valves of the heart: (4) Bicuspid
,Tricuspid
Pulmonary Semi-Lunar valve
Aortic Semi-Lunar valve
Function of valves in the heart Allows blood to flow in one direction
Prevent backflow or regurgitation of blood
Opens and closes when the heart relaxes and contracts
Allows blood to flow in one direction Valves
Prevent backflow or regurgitation of blood Valves
Opens and closes when the heart relaxes and contracts Valves
Tricuspid Valve AKA: right atrio-ventricular valve
Bicuspid Valve AKA: mitral valve
valve located between the right atrium and right ventricle Tricuspid valve
Has 3 cusps or flaps Tricuspid valve
,Tricuspid valve allows blood to flow from: Right atrium to right ventricle, but not in opposite
direction
Bicuspid valve location located between the left atrium and left ventricle
Has two cusps or valves Bicuspid valve
Bicuspid valve allows blood to flow: from left atrium to left ventricle
Pulmonary Semi-Lunar valve is found: at the orifice/opening of the pulmonary trunk
Pulmonary Semi-Lunar valve allows blood to flow from the righ ventricle into the pulmonary
trunk which in turn delivers blood to the lungs
Aortic Semi-Lunar valve is located at the orifice of the aorta
Located at the orifice of the aorta Aortic Semi-Lunar valve
Allows blood to flow from the righ ventricle into the pulmonary trunk which in turn delivers
blood to the lungs Pulmonary Semi-Lunar valve
Permits blood to leave left ventricle and flow into the aorta (ascending aorta) Aortic Semi-
Lunar valve
Aortic Semi-Lunar valve permits blood to leave left ventricle and flow into the aorta
(ascending aorta)
, The right atrium receives blood from which three veins Superior Vena Cava: returns blood
from all areas above the diaphragm
Inferior Vena Cava: returns blood from areas inferior to the diaphragm
Coronary Sinus: located in the posterior wall of the right atrium and returns blood from
coronary circulation
Returns blood from all areas above the diaphragm Superior Vena Cava
Returns blood from areas inferior to the diaphragm Inferior Vena Cava
Located in the posterior wall of the right atrium and returns blood from coronary circulation
Coronary Sinus
Systemic Circulation, which includes coronary circulation terminates in the ______ _______ via
these three veins: (3) Right Atrium
Superior Vena Cava, Inferior Vena Cave, Coronary Sinus
Right Atrium Contains Pectinate Muscles: muscular ridges located in the anterior wall
Fossa Ovalis: an oval depression located in the septal wall of the right atrium
Muscular ridges located in the anterior wall. Pectinate Muscles
These ridges run parallel to each other and resemble the teeth in a comb Pectinate Muscles
