61

a three layered blood vessels that carries blood HIGH in oxygen away from the heart of a living person.

artery

62

As arteries move away from the heart they lose which layer?

tunica adventitia layer

63

(tiny arteries) - a two layer blood vessel carrying blood away from the heart of a living person. Only contains tunica media and tunica intima

Arteriole

64

As the artery continues to move away from the heart the next (2nd) layer lost is?

tunica media (muscle layer)

65

a single layered blood vessel. Only contains tunica intima

It is at this point that the arterial portion of the blood vascular system unites with the venous portion of the blood vascular system and the process reverse.

In Reverse - The tunica media (muscle layer) reappears

capillary

66

(a tiny vein) -two layered blood vessel carrying blood toward the heart of a living person.

The Tunica adventitia (externa) then reappears

venule

67

three layered blood vessel that carries blood toward the heart of a living person

veins

68

Layers making up a vein are ________ than that of an artery.

thinner

69

The capillary level is where life occurs. The walls are so thin blood has to line up to pass.

Veins are the suction side as blood moves toward the heart of a living person. Veins start small and as the venule or tunica media (muscle layer) reappears, it leaves a two layer vein carrying blood to the heart. As blood continues, the tunica intima (interna), third layer, or vein reappears carrying blood toward the heart of a living person. Layers of a vein are thinner and can be ruptured more easily. 85% of blood shifts to the venous side of the body following death. Veins are equipped with valves to prevent the back flow of blood going towards the heart of a living person from going to the lowest point to prevent the back flow.

--

70

blood vessels that feed the outer layers of arteries, arterioles, veins, and venules. This is the red squiggly line found on blood vessels by which to differentiate an artery from a nerve.

Vasa vasdrum

71

alternate (secondary) route of blood flow

Collateral circulation

72

normal blood pressure

120/80

73

top number of a blood pressure reading. the contraction phase of the cardiac cycle. Contraction of the ventricles

systole
(systolic pressure)

74

bottom number of a blood pressure reading. the resting phase of the cardiac cycle. Contraction of the two small atria (upper chambers)

diastole
(diastolic pressure)

75

low in oxygen blood; most important in embalming to establish and maintain drainage.

right atrium

76

receives blood from the lungs

left atrium

77

pumps unoxygenated blood to the lungs to pick up oxygen

right ventricle

78

largest and strongest muscle of the heart; last pump of blood with oxygen to the body via arteries

left ventricle

79

venous side; blood low in oxygen

right side

80

artery side; blood high in oxygen

left side

81

Large artery which first ships blood low in oxygen from the heart toward the lungs

pulmonary trunk

82

the largest artery in the human body.

aorta

83

The plural cavity only surrounds the

lungs
