Ch. 14 A&p The Circulation Of The Blood

Front 1

Three coats or layers found in both arteries and veins

Back 1

Tunica externa
Tunica Media
Tunica Intima

Front 2

Which layer is smooth muscle found in blood vesseles

Back 2

Tunica Media (middle)

Front 3

Outer most layer of blood vessels

Back 3

Tunica Externa

Front 4

The inner layer of endothelial cells that lines arteries and veins

Back 4

Tunica intima

Front 5

This muscle layer is much thicker in arteries than it is in veings so that it can resist greater pressures

Back 5

Tunica media

Front 6

Layer of blood vessels that plays a critical role in maintaining blood pressure and controlling blood distribution. made of smooth muscle

Back 6

Tunica media

Front 7

What is the capillary membrane composed of

Back 7

only one layer of flat, endothelial cells. The tunica intima

Front 8

Smooth muscle cells that guard the entrances to the capillaries and determine how much blood will flow into each capillary bed

Back 8

Precapillary sphincters

Front 9

Single layer of cells found in blood vessels that provides a very smooth lining that prevents the accidental formation of blood clots

Back 9

Tunica Intima

Front 10

Largest of the three layers in an artery

Back 10

Tunica Media

Front 11

Largest of the three layers found in a vein

Back 11

Tunica externa

Front 12

Decreased blood supply to a tissue, involves the gradual death of cells and may lead to complete tissue death

Back 12

Ischemia

Front 13

Tissue death

Back 13

Necrosis

Front 14

Necrotic tissue that has progress to the point of decay

Back 14

Gangrene

Front 15

Sclerosis

Back 15

hardening

Front 16

veins in which blood tends to pool rather than continue on toward the heart

Back 16

Varicose veins or Varices

Front 17

Vericose veins in the rectum

Back 17

Hemorrhoids

Front 18

Vein inflammation caused by an IV

Back 18

Phlebitis

Front 19

route of blood through the liver

Back 19

Hepatic Portal circulation

Front 20

Organs whose blood does not pour directly into the inferior vena vaca

Back 20

spleen
stomach
pancreas
gallbladder
intestines

Front 21

Results from any type of heart failure, such as that after severe myocardial infarction, heart infections, and other heart conditions. Because the heart con no longer pump blood effectively, blood flow to the tissues of the body decreases or stops

Back 21

Cardiogenic shock

Front 22

Results from the loss of blood volume in the blood vessels. Reduced blood volume results in low blood pressure and reduced flow of blood to tissues. Hemorhage is a common cause

Back 22

Hypovolemic shock

Front 23

Can be caused by loss of interstitial fluid, causing blood plasma to drain out of the vessels and into the tissue spaces.

Back 23

Hypovolemic shock

Front 24

causes include Diarrhea, vomiting, dehydration, intestinal blockage, severe or extensive burns, and some other conditions.

Back 24

Hypovolemic shock

Front 25

Results from widespread dilation of blood vessels caused by an imbalance in autonomic stimulation of smooth muscles in vessel walls

Back 25

Neurogenic shock

Front 26

Shock caused by injury to the spinal cord or medulla, depressived drugs, or emotional stress where widespread vasodilation reduces blood pressure, reducing blood flow

Back 26

Neurogenic shock

Front 27

Results from an acute allergic reaction called anaphylaxis and has the same kind of blood vessel dilation characteristics as neurogenic shock

Back 27

Anaphylactic shock

Front 28

A condition in which infectious agents release toxins into the blood. The toxins dilate blood vessels, thereby causing shock. Often accompanied by fever

Back 28

Septic shock

Front 29

Type of septic shock which usually results from staphylococcal infections that begin i nthe vagina or menstruating women and spread to the blood

Back 29

Toxic Shock Syndrom (TSS)

Front 30

A section of an artery that has become abnormally widened because of a weakening of the arterial wall.

Back 30

Aneurysm

Front 31

Sometimes form a scalike extension of the arterial wall

Back 31

Aneurysm

Front 32

The structure used to bypass the liver in the fetal circulation

Back 32

Ductus venosus

Front 33

The foramen ovale serves the fetal circulation by

Back 33

shunting blood from the right atrium directly into the left atrium

Front 34

the structure used to connect the aorta and pulmonary artery in the fetal circulation

Back 34

Ductus arteriosus

Front 35

allows most blood from the placenta to bypass the fetal liver in fetal circulation

Back 35

Ductus venosus
