Term
|
Definition
-supplies oxygen and nutrients to all cells in body
-consists of blood, blood vessel, heart |
|

-two main components are plasma and cells
-approx. 45% cells, 55% plasma |
|

|
Definition
-contain haemoglobin
-life span= 100-120 days
-recycled by macrophages in spleen |
|
|
Term
|
Definition
| protein with attached iron molecules for binding to oxygen |
|
|
Term
|
Definition
-excess RBCs
-causes: low pressure(elevations); COPD- diffusion of oxygen is poor |

Term
| White blood cells and platelets |
|
Definition
-leukocytes (WBC)
-thrombocytes (platelet) |
|
|
Term
|
Definition
-rid body of foreign material and organisms
-main role of destroying pathogens
-innate immune response
-adaptive immune response
-aid in recycling old cells and cell parts |
|
|
Term
|
Definition
-cellular fragments
-formed from megakaryocytes
-life span 8ish days
-function in clotting |
|
|
Term
|
Definition
-stick to endothelium (lining of blood vessels) and to each other via dense network of receptors on membrane surface
-positive feedback loop |
|
|
Term
|
Definition
-mostly salt water (90%) and nutrients (glucose)
-also contains proteins
-carries dissolved gases and waste products
-helps to regulate pH of blood and tissue
-carries ions for majority of physiological processes |
|
|
Term
|
Definition
-system of "pipes" of various sizes
-control and direct flow of blood throughout the body
-carry blood around body to provide oxygen and nutrients
-many physiological mechanisms in place that utilize vascular tissue
-control blood pressure
-shunt blood where needed most |
|
|
Term
|
Definition
| arteries, arterioles, capillaries, venules, veins |
|
|
Term
|
Definition
| large vessels that carry oxygenated blood to the body (exception: pulmonary artery) |
|
|
Term
|
Definition
-smaller than arteries
-beginning of gas exchange
-separated from capillaries by precapillary sphincters
-muscles that open to allow blood to move forward, prevent blood from flowing backwards
-also able to close to allow blood to be shunted to the core during shock |
|
|
Term
|
Definition
-very small
-cells must pass in single file line
-virtually all tissue contains capillary beds
-after gas exchange, deoxygenated blood exits capillaries to venules |
|
|
Term
|
Definition
-carry deoxygenated blood to heart
-much larger than capillaries
-low pressure
-serves as reservoir for blood
-valves prevent backflow of blood due to gravity |
|
|
Term
|
Definition
-corresponding vein to most major arteries
-muscle contractions and valves: contractions of muscles surrounding the veins push blood toward the heart. valves within the veins keep the blood on course by preventing it from moving backward |
