1

What blood vessels carry oxygenated blood away from the heart?

Arteries

2

Smaller branches of arteries?

Arterioles

3

Capillaries are?

the smallest vessels, with thin walls for exchange.

4

What blood vessels carry deoxygenated blood back to the heart?

Veins

5

Smaller branches that return deoxygenated blood to veins are?

Venules

6

Exceptions to the regular oxygenation naming convention?

- Pulmonary arteries
- Pulmonary veins

7

Carry deoxygenated blood away from the right ventricle to the lungs for gas exchange?

Pulmonary Arteries

8

Return oxygenated blood to the left side of the heart?

Pulmonary Veins

9

Three layers of vessel walls

- Tunica intima
- Tunica media
- Tunica adventitia

10

Tunica intima

inner, smooth layer of the blood vessel

11

Tunica media

middle, smooth muscular layer and elastic tissue

12

Tunica adventitia

outer, elastic layer and fibrous connective tissue.

13

What does the coronary circulation comprise?

Blood vessels that supply blood to the heart.

14

What veins drain deoxygenated blood from the myocardium and return it to the right atrium through the coronary sinus?

Coronary veins

15

These new connections are referred to as collateral circulation?

Anastomoses (connections or openings)

16

Which arteries can develop anastomes?

Coronary arteries

17

When do Coronary arteries develop connections or openings (anastomoses) when blood flow is not sufficient for various reasons, such with occlusions so that blood can flow?

when there is:
- plague
-thrombi

18

What veins drain deoxygenated blood from the myocardium and return it to the right atrium through the coronary sinus?

Coronary veins

19

What is the Tunica media responsible for?

For the vessel’s ability to change diameter.

20

Which layer of wall vessel provides the necessary "give" to accommodate the rush of blood with each cardiac contraction?

Tunica adventitia

21

An example of a large artery?

Aorta

22

An example of veins?

Superior and inferior venae cavae

23

(large arteries and veins)
A network of small blood vessels that contain nerve endings?

Vasa vasorum

24

Provides nutrients and oxygen as well as remove waste product?

vasa vasorum

25

Which system returns excess interstitial fluid (lymph) to circulation?

Lymphatic system

26

The lymphatic system includes which organs?

-lymph nodes
-spleen
-thymus
-tonsils

27

The lymphatic system plays a role in?

Immunity

28

Movement of lymph resembles?

blood movement

29

In the lymphatic system, fluid outflow normally?

Exceeds fluid returned

30

Tissue flooding that occurs when amount of lymph produced exceeds the capacity of the system?

Edema
