oo T-Mobile Wi-Fi 3:41 AM content.learntoday.info I. Explain how blood vessel length, vessel diameter, and blood viscosity affect blood flow through the cardiovascular system. Answer: 2 Explain the effects of aspirin on blood viscosity and blood flow? Answer: 3. Explain the how blood types and Rh factor are determined based on antigen and antibody properties. Answer: 4. Describe how to visually differentiate the five white blood cells. Answer 5. Using the picture of the blood cells as a reference, identify each cell type in the space provided o0 b. CRasmussen ConfidentialExplanation / Answer
1. ANS: Vessel length: If the vessel had more length, then there is more resistance against blood flow the longer the vessel is which slows down blood flow.
Vessel diameter: If the vessel is wider, then more blood can pass through it.
Ex: Aorta, it is extremely wide and allows a lot of blood to go through at one time.
Blood viscosity (thickness): If the viscosity is higher, then the flow of blood can becomes harder. Vessels are like a river, and blood is like water.
2. ANS: Some studies can suggested that aspirin may have a viscosity lowering effect. But the study on adult males with normal lipid levels can show that aspirin had no significant effect on blood viscosity.
Aspirin plus dipyridamole was shown to be more effective than aspirin alone in reducing diastolic blood viscosity. If the blood had a higher viscosity then it had slower the blood flows (more sluggishly).
3. ANS: Blood types differentiation is completely based on specific antigen on the surface of the red blood cells. Antigens are two types, they are A and B Antigens.
Type A blood will have only A antigens (anti B antibodies)
Type B blood will have only B antigens (anti A antibodies)
Type AB blood will have both A & B antigens (No antibodies)
Type O blood has no antigens (A & B antibodies)
Because of these antibodies one type of blood can reject other type blood. So the Rh factor is determined by whether or not another antigen can be found on the red blood cells (this would make the blood +) or there is no other antigen on the red blood cells (this would make the blood -).
4. ANS: Neutrophil: It contains multi lobed nucleus (2-6) and the cytoplasm was present in lilac colour.
Eosinophil: It contains two lobed nucleuses and the cytoplasm was present in red or dark colour.
Basophil: The cell has dark black granules everywhere.
Lymphocyte: It contains single nucleus and its size is similar to RBC.
Monocyte: It contains U shaped nucleus and these are the biggest cell among all the white blood cells.
