Study These Flashcards
A

TRICUSPED
PULMONARY (SEMILUNAR)
BICUSPID (MITRAL)
AORTIC (SEMILUNAR)

25
3 distinct sections/cusps. Regulates or controls the opening between the right atrium and right ventricle. *controlled by papillary muscles & chordae tendineae in rt ventricle
TRICUSPED
26
3 distinct cusps. Controls opening of right ventricle and pulmonary trunk *NOT controlled by papillary muscles or chordae tendinea.
PULMONARY (SEMILUNAR)
27
2 distinct cusps (only one) regulate or control opening between left atrtium and left ventricle *controlled by papillary muscles & chordae tendinea in lft ventricle
BICUSPID (MITRAL)
28
3 distinct cusps relies on backflow of blood to function, controls opening between left ventricles and AORTA (largest artery). Blood sitting will fill the two coronary arteries that supply hearts its blood
AORTIC (SEMILUNAR)
29
Orifices of the heart:
``` SUPERIOR VENA CAVA (SVC) INFERIOR VENA CAVA (IVC) RIGHT ATRIOVEATRICULAR (RIGHT AV) LEFT ATRIOVEATRICULAR (LEFT AV) CORONARY SINUS ORIFICE PULMONARY VEIN ORIFICE PULMONARY TRUNK AORTIC ORIFICE ```
30
opening of the SVC directly into right atrium of the heart; 2nd largest vein in body; it will eventually drain any blood originating from head/neck/upper extremities/thoracic cavity. Named by angle/direction it enters atrium
SUPERIOR VENA CAVA (SVC)
31
opening of IVC directly into the right atrium of the heart; largest vein in human body; Will drain any blood from abdomen and lower extremities. It is the occupying vein of descending aorta; named by angle or direction it enters heart.
INFERIOR VENA CAVA (IVC)
32
opening between right atrium and right ventricle; regulated by the tricuspid valve
RIGHT ATRIOVEATRICULAR (RIGHT AV)
33
opening between left atrium and left ventricle. Regulated by the bicuspid valve (mitral valve)
LEFT ATRIOVEATRICULAR (LEFT AV)
34
opening of the coronary sinus directly into the right atrium. The coronary sinus is the large vein that drains low-oxygen blood from the heart itself
CORONARY SINUS ORIFICE
35
4 openings of pulmonary veins and directly into left atrium; only vein carry blood high in oxygen; two from each side of the lung
PULMONARY VEIN ORIFICE
36
single opening between right ventricle and pulmonary trunk; ship low-oxygen blood from right side of heart to lungs; control by pulmonary (semilunar) valve
PULMONARY TRUNK
37
opening between left ventricle and aorta (largest artery). Aortic semilunar valve controls this opening
AORTIC ORIFICE
38
2 way exchange of blood between heart & lungs. Uses right ventricle (RV) to begin; and ends in the left atrium (LA). This is how blood becomes oxygenized
PULMONARY CIRCULATION
39
2 way exchange of blood between the heart and the rest of the body; except the lungs. Starts in the left ventricle (LV) and ends in right atrium (RA). Takes oxygen to the body and returns the waste.
SYSTEMIC CIRCULATION
40
The hole (oval shaped) naturally present between upper chamber of heart to bypass shipment of blood to lungs. It then becomes an oval shaped shallow depression best seen in right atrium of heart after birth
FORAMEN OVALE FOSSA OVALIS
41
Passageway or duct between the pulmonary trunk and the aorta of heart, it then becomes a ligament with no passageway.
DUCTUS ARTERIOSUS LIGAMENTUM ARTERIOSUM
42
Single vein located between the umbilical vein and the IVC during fetal circulation then turns into white band that runs between the livers two lobes
DUCTUS VENOSUS LIGAMENTUM VENASUM
43
Two arteries that ship low oxygen blood away from fetal heart toward placenta. It is inside umbilical cord at birth and falls off with umbilical cord falling off
UMBILICAL ARTERIES LATERAL UMBILICAL LIGAMENTS
44
Blood vessel that ships high oxygen from placenta toward fetus then after birth it is part of umbilical cord that falls off
UMBILICAL VEIN LIGAMENTUM TERES OF LIVER
45
fetal formations into adult counterparts
Fetal Circulation
46
Outermost layer of the 3 layer-blood vessels in the human body; elastic tissue allow to stretch to surface
Tunica Adventita
47
Muscle layer; smooth muscle layer of blood vessels; allow for shipment of blood
Tunica Media
48
Innermost layer of any blood vessels; only layer found throughout the body
Tunica Intima
49
3 layer blood vessel that carries blood away from heart. As the artery continues to move away from the heart the next layer, the tunica media (muscle layer) is lost.
Artery
50
Literal tiny artery; 2 layer blood vessels that carries blood away from heart
Arteriole
51
Single layer blood vessel that joins arterial system with the venous system; where life occurs; walls so thin blood has to line up to pass
Capillary
52
literal tiny vein; 2 layer blood vessels to heart
Venule
53
3 layer blood vessel carries blood to heart; 85% if blood shifts to this side following death.
Vein
54
blood vessels that feed the outer layers of blood vessels (arteries, arterioles, veins, and venuals); little red squiggle lines; method to differentiate an artery from a nerve
Vasa Vasorum
55
alternate (secondary) route where blood is shipped throughout body
Collateral Circulation
56
Measurement of milliliters of mercury displaced : 120 80
Blood pressure
57
individual sections of a human heart valve.
Cusps
58
Study of Vessels (blood and lymph vessels).
Angiology
