-
3 general functions of blood
- transportation- respiratory gas, nutrients
- regulation- body temp, PH, fluid balance
- protection- against blood loss and disease
-
specialized connective tissue of blood
formed elements- 45%,- WBC, RBCs, Platelets
Plasma= Fluid portion and fibrinogen- Proteins, Water, Other solutes
-
3 main proteins for blood plasma
albunin, globulins, fibrinogen
-
plasma proteins- 3 components
albumins, globulins, fibrinogens
-
albumins
1 of 3 types of plasma proteins
- smallest and most abundant plasma proteins,
- make up 58% of total proteins
- Exerts greatest colloid osmotic pressure- helps maintain blood volume and pressure.
- Acts as transport proteins- carry ions, hormones, some lipids
-
globulins
1 of 3 types of plasma proteins
- 2nd largest group
- Make up 37% of total proteins
- Smaller alpha globulins and larger beta globulins- transport some water insoluble molecules, hormones, metals, ions
- Gamma Globulins- immunoglobulins or antibodies- help in bodies defense
-
fibrinogen
1 of 3 types of plasma proteins
- make up 4% of total proteins
- contributes to blood clot formation
- Following trauma, converted o insoluble fibrin strands
- Plasma with clotting proteins removed- serum
-
serum
plasma with clotting protein removed
-
formed elements
- include cells and cell fragments-
- erythrocytes,
- thrombocytes
- Leukocytes
-
Erythrocytes
- Type of formed elements
- most numerous
-
thrombocytes
type of formed elements
- platelets
- hundred of thousands
-
Leukocytes
- type of formed elements
- 2 types:
- A) Granular- Neutrophils, Eosinophills, Basophills
- B) Agranular- Monocytes, Lymphocytes, T cells, B Cells
-
Hematopoesis
process by which blood cells are formed from hematopoietic stem cells called hemotocytoblasts
