Systemic Circulation |
The longer circulation system |
|
Pulmonary Circulation |
The shorter circulation system |
|
Heart |
Is a hollow muscular four chambered organ that pumps blood
|
|
Four types of blood vessels |
1. Arteries 2. Veins 3. Capillaries 4. Sinuosoids |
|
Arteries |
This blood vessel carries blood from the heart away to the capillaries |
|
Pulmonary circulation |
This circulation carries poor oxygen blood from heart to the lungs |
|
Systemic circulation |
This circulation carries rich oxygen blood from heart to the lungs |
|
Capillaries |
Composed of endothelium and its basement membrane, connects the arterioles and venules |
|
Capillaries |
Site of exchange of CO2 O2 nutrients and waste |
|
Microcirculation |
This circulation is the flow of blood from arterioles to venules |
|
Vascular shunt |
This vessel is a metarteriole-thoroughfare channel |
|
True cappilaries |
Actual exchange cessels |
|
Metarteriole |
Vessel structurally intermediate between cappilary and venule |
|
Thoroughfare channel |
Vessel structurally intermediate between capillary and venule |
|
Precapillary sphincters |
smooth muscle that regulates blood flow in the capillaries |
|
Pulmonary veins |
veins that return oxygenated blood to the heart from the lungs |
|
Systemic veins |
veins that return deoxygenated blood to the heard from the rest of the body |
|
Venae comitante |
closely accompany muscular arteries in the limbs |
|
Veins |
Has wider lumens |
|
Arteries |
Transports blood under high pressure |
|
Arteries |
Do not have valves |
|
Lymphatic system |
This system transports excess interstitial fluid which was initially formed as blood filtrate, back to the blood stream |
|
Lacteals |
Transports Lymph Transports the product of fat absorption away from the digestive tract |
|
Lymph |
tissue fluid that enters the lymphatic capillaries |
|
Edema |
accumulation of tissue fluid due to inadequate lymphatic drainage |
|
Lymph ducts |
Lymphatic vessel that is bigger than lymph capillaries |
|
Lymph nodes |
Lymphocyte production and contains phagocytes |
|
Cisterna chyli |
saclike enlargement of the thoracic duct |
|
Brachiocephalic artery |
divides into the right common carotid artery and the right subclavian artery. |
|
Left common carotid |
major blood vessels in the neck that supply blood to the brain, neck, and face. |
|
Left subclavian |
These carry oxygenated blood up to the brain from the base of the neck. |
