dorsalis pedis.

7

The the back of the leg, the ___ artery travels down behind the medial malleolus and forms the plantar arteries in the foot.

8

The function of the arteries is to ___.

supply oxygen and essential nutrients to the cells.

9

a deficient supply of oxygenated arterial blood to a tissue caused by obstruction of a blood vessels.

Ischemia

10

The course of veins is ___ to the course of arteries.

Parallel

11

Body has more ___, and they lay ___ to the skin.

veins
closer

12

Function: to drain deoxygenated blood and it’s waste products from tissue and return it to the heart.

veins

13

veins are called capacitance vessels because ___

of their ability to stretch.

14

Deep veins in the leg:

the femoral and popliteal veins

15

Superficial veins in the leg:

the great and small saphenous

16

Perforator veins:

connecting veins that join the deep and superficial veins.

17

The veins do not have a pump to generate their blood flow so they need a _____

mechanism to keep blood moving

18

The mechanism is accomplished by:

contracting skeletal muscles, pressure gradient caused by breathing, and intraluminal valves.

19

In the legs, the mechanism for venous flow is called ____

calf pump or peripheral heart.

20

Dilated and tortuous (varicose) veins create ____ valves leading to increased venous pressure, which further dilated the vein.

incompetent

21

Lymphatic system retrieves what and from/to where?

excess fluid and plasma proteins from the interstitial spaces and returns them to the bloodstream.

22

Caused by the pumping action of the heart and pushed somewhat more fluid out of the capillaries than the venules can absorb.

Hydrostatic pressure

23

pulls interstitial fluid back into the venules

colloid osmotic pressure

24

25

The thoracic duct drains the ____ and empties it into the ___.

Rest of the body, and empties into the left subclavian vein.

26

Lymphatic system functions:

Conserve fluid and plasma proteins that leak out of capillaries

Form a major part of immune system that defends body against disease

absorbs lipids from intestinal tract

27

small oval clumps of lymphatic tissue located at intervals along vessels

lymph nodes

28

superficial

29

located in the left upper quadrant of the abdomen

spleen

30

spleen’s four functions:

destroy old red blood cells
produce antibodies
store red blood cells
filter microorganisms from the blood
