Q

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

A 
Tunica adventitia (tunica externa) 
Tunica media (muscle layer) 
Tunica intima (interna) .
58
Q

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.

A

Tunica adventitia (tunica externa)

59
Q

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

A

Tunica media (muscle layer)

60
Q

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

A

Tunica intima (interna)

61
Q

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

A

artery

62
Q

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

A

tunica adventitia layer

63
Q

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

A

Arteriole

64
Q

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

A

tunica media (muscle layer)

65
Q

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

A

capillary

66
Q

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

The Tunica adventitia (externa) then reappears

A

venule

67
Q

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

A

veins

68
Q

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

A

thinner

69
Q

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.

A

–
