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
