Blood transports substances and maintains homeostasis in the body
What kind of tissue is blood?
Composed of 2 basic components
1. Cells (rbc, wbc, platelets)
2. Plasma (water, amino acids, vitamins, hormones, electrolytes, cellular waste)
What is their shape?
How many are found in a cubic millimeter?
What cell structure is missing from blood cells?
What is hematopoeisis?
How are old blood cells destroyed?
What hormone causes the production of rbc's?
- transport O2 throughout body, removes CO2
- Hemoglobin = molecule which combines with O2 to transport it
Oxyhemoglobin - plenty of oxygen, color =
Deoxyhemoglobin - not carrying much O2, color =
*HUMAN BLOOD IS NEVER BLUE*
Elements Critical for RBC Production =
Anemia = too few RBC
General function - defend the body against disease-causing agents (microorganisms)
|Granulocytes (granular cytoplasm)||1. Neutrophils|
|Agranulocytes (lacking granular cytoplasm)||4. Monocytes|
- help initiate formation of blood clots, close breaks in damaged blood vessels
- the liquid portion of the blood, 92% water
- transport nutrients, gases, vitamins, maintain fluid and electrolyte balance, and pH
1. Albumins -
2. Globulins -
3. Fibrinogen -
- the process of stopping bleeding. Involves coagulation and the clotting of blood to seal site of damage, 3 Key Events:
1. Blood vessel spasm =
2. Platelet plug formation =
3. Blood coagulation =
Thrombin causes change of fibrinogen to fibrin, which trap platelets and blood cells to form a hematoma
1. What is the percentage of cells and plasma in a sample of human blood? ___________________________________
2. Platelets release a vasoconstricting substance called: ____________________________________
3. The most common white blood cells are the : __________________________________________
4. The formation of new blood cells is called: ________________________________________________
5. What chemical produces and inflammatory reaction? _______________________________________________
6. Type of WBC that is responsible for attacking parasitic infection: _______________________________________
(For each, focus on the causes, symptoms and possible treatments)
1. Carbon Monoxide Poisoning
Aplastic Anemia -
Hemorrhagic anemia -
Pernicious anemia -
Sickle Cell Anemia (genetic) -
5. Blood Poisoning - Septicemia
10. Beta Thalassemia
