31

is the key chamber to establish drainage in embalming.

right atrium

32

the large vein which drains blood from the heart itself

coronary sinus

33

carry blood high in oxygen away from the heart of a living human. They become smaller away from the heart

arteries

34

start small and become larger closer to the heart. carries blood low in oxygen toward the heart.

veins

35

- the opening of the superior vena cava (the angle it enters the right atrium of the heart - superiorly or top) (SVC) directly into the right atrium of the heart.

superior vena cava orifice

36

(Angle it enters the right atrium of the heart - inferiorly or bottom). The opening of the inferior vena cava (IVC) directly into the right atrium of the heart

inferior vena cava orifice

37

the opening located between the right atrium and right ventricle. In turn controlled by the tricuspid valve

Right atrioventricular orifice

38

the opening located between the left atrium and left ventricle. Only controlled by the bicuspid or mitral valve

Left atrioventricular orifice

39

the opening of the coronary sinus directly into the right atrium of the heart.

Coronary sinus orifice

40

the four opening of the pulmonary veins directly into the atrium of the heart.

Pulmonary vein orifices

41

the opening located between the right ventricle and the pulmonary trunk.

Pulmonary trunk orifice

42

the opening between the left ventricle and the aorta (the largest artery in the human body)

Aortic orifice

43

right ventricle and left atrium- the two way exchange of blood between the heart and the lungs

pulmonary circulation

44

The only two chambers of the heart involved in pulmonary circulation are the ______ and the __________
The _________ is the chamber of the heart in which pulmonary circulation begins. The__________ is where pulmonary circulation ends.

right ventricle
left atrium
right ventricle
left atrium

45

left ventricle and right atrium- the two way exchange between the heart and the rest of the body except for the lungs

Systemic circulation

46

The only two chambers involved in systemic circulation are the ________ and the ________.
The__________ of the heart is where systemic circulation begins. The _________ is where systemic circulation ends.
Systemic circulation would include a study of an openings of the heart valves, orifices of the heart, an arteries or veins of the body that are involved in this two way exchange of blood and the body, EXCEPT THE LUNGS

left ventricle
right atrium
left ventricle
right atrium

47

oval shaped opening naturally present between the atria or upper chambers of the fetal heart

foramen ovale

48

oval shaped shallow depression of the heart, best seen in the right atrium of the adult heart. These changes need to occur shortly after birth.

fossa ovalis

49

- a passageway for blood, located between the pulmonary trunk and the aorta, in fetal circulation. Designed to shunt or bypass shipment to the fetal lungs

Ductus arteriosus

50

adult counterpart structure of ductus arteriosus. It should turn into a ligament shortly after birth. It shouldn’t carry blood after you are born

ligamentum arteriosum

51

A single vein present in fetal circulation designed to shunt or bypass shipment of blood the fetal liver

Ductus venosus

52

is the adult counterpart structure of the ductus venosus. It should turn a ligament shortly after birth

Ligamentum venosus

53

two arteries of fetal circulation that carry blood low in oxygen and high in waste products from the fetus to the placenta

umbilical arteries

54

– the adult counterpart of the two umbilical arteries.

Lateral umbilical ligaments

55

the single vein which conveys blood high in oxygen and useable food substances from the placenta to the fetus

Umbilical vein

56

the adult counterpart of the umbilical vein

Ligamentum teres of the liver

57

Layers of Blood vessels (Arteries) -Outer most to inner most

Tunica adventitia (tunica externa)
Tunica media (muscle layer)
Tunica intima (interna) .

58

outer most layer of the three layers (elastic tissue) of blood vessels. Function is to allow the embalmer to stretch the vessel to the surface.

Tunica adventitia (tunica externa)

59

middle layer of a three layer blood vessel. Known as smooth (visceral) muscles. Allow for shipment of blood.

Tunica media (muscle layer)

60

inner most layer. The only layer continuous, which means it is found in every blood vessel of the human body

Tunica intima (interna)
