How thick is blood
|
4 times as thick as water.
|
|
|
Blood contains
|
cells, plasma and protein
|
|
|
centrifuge.
|
Machine that spins Whole blood so it can be broken down into into it’s liquid and cellular components
|
|
|
Whole blood
|
formed elements and the liquid plasma.
|
|
|
Formed Elements
|
Erythocytes and the buffy coat.
|
|
|
Buffy coat
|
1. Leukocytes or white blood cells
2. Platelets, cell fragments. |
|
|
Plasma
|
straw colored liquid. 50% of blood
|
|
|
erythrocytes.
|
Make up more than 99% of formed elements
Primary function is to transport respiratory gases in the blood |
|
|
Leukocytes
|
1. Make up less than .01% of formed elements
2. Contribute to defending the body against pathogens. |
|
|
Platelets
|
1. Make up less than 1% of formed elements
2. help with blood clotting. |
|
|
Leukocytes =
|
immune response.
|
|
|
Platelets & Blood protein
|
1. for clotting
|
|
|
Serum =
|
When the proteins are removed from the plasma. 92% of plasma is water. water facilitates the transport of materials in the plasma.
|
|
|
Red blood cells
|
Transports O2 and CO2
last 120 days. Shape. Biconcave disks. |
|
|
Buffy coat location
|
inbetween plasma and red blood cells
|
|
|
PLASMA PROTEINS
|
1. Albuimins
2. Globulins 3. Fibrinogen 4. Regulatory Proteins |
|
|
1. Albuimins
|
1. Smallest and most abundant of the plasma proteins.
2. Albumins act as a transport proteins that carry inos, hormones, and some lipids in the blood. |
|
|
2. Globulins
|
1. Second largest group of plasma proteins
2. Also called immunoglobulins or antibodies 3. Produced by some of our defense cells to protect the body against pathogens that may cause disease |
|
|
Fibrinogen
|
1. makes up about 4% of all plasma
2. Responsible for blood clot formation 3. following trauma to the walls of blood vessels, fibrinogen is converted into long, insoluble stands of fibrin, which is the essence of a blood clot |
|
|
Regulatory Proteins
|
1. Form very minor class of plasma proteins. Includes enzymes
|
|
|
Enzymes
|
proteins that accelerate chemical reactions in the blood and hormones.
|
|
|
Hematocrit=
|
Percentage of erythrocytes in the blood.
|
|
|
Hemoglobin=
|
red pigmented protein in the erythrocytes.
1. Transports oxygen and carbon dioxide, and is responsible for the charactersitc bright red color of arterial blood. |
|
|
Hemopoiesis=
|
Process of making new formed elements AKA hematopoiesis (poiesis = making). ei. recycling red blood cells.
|
|
|
Macrophage=
|
Big Eater.
|
|
|
Platelets
|
Thrombocytes another name
|
