Blood
| Question | Answer |
|---|---|
| What is the blood volume of an average sized adult male? | 5 to 6 liters |
| What is the blood volume of an average sized female? | 4 to 5 liters |
| What determines whether blood is bright red or a dull brick red? | The amount of oxygen it is carrying. Oxygen rich blood is bright red. |
| neutrophil | most numerous leukocyte |
| What are the three WBC granulocytes? | neutrophil, eosinophil, and basophil |
| What are the agranulocytes | lymphocytes & monocytes |
| What is the precursor cell of platelets? | megakarycyte |
| Which cell is involved in destroying parasitic worms? | eosinophil |
| Which cell releases histamine; promotes inflamation? | basophil |
| Which cell produces antibodies? | lymphocyte |
| Which cell transports oxygen? | red blood cells |
| What is primarily water, noncellular, and the fluid matrix of blood | plasma |
| Which cell exits a blood vessel to develop into a macrophage? | monocytes |
| NLMEB | never let moneys eat bananas |
| What are the five types of white blood cells? | neutrophils, lymphocytes, monocytes, eosinophils, basophils |
| List four classes of nutrients normally found in plasma | amino acids, glucose, fatty acids, vitamins |
| Name two gases found in plasma | carbon dioxide & oxygen |
| Name three ions found in plasma | sodium, potassium, and calcium |
| Describe the consistency and color of plasma | (slippery) gelatinous fluid unlike water; has a straw like color to it (yellow) |
| What is the average life span of a red blood cell? | duration of development is about 15 days. life span 100 to 200 days. |
| How does the red blood cell's anuceate condition affect its life span? | they are unable to reproduce or repair damage caused to it during circulation |
| describe eosinophils | bilobe nucleus, contains large cytoplasmic granules (elaborate lysosomes), stains red - orange. |
| describe neutrophils | nucleus consists of 3 to 6 lobes and pale lilac cytoplasm contains fine cytoplasmic granules |
| describe lymphocytes | nucleus spherical or slightly indented, accounts for most of the cells mass, cytoplasm appears as a thin blue rim around the nucleus |
| describe basophils | large U or S shaped nucleus with 2 or more indentations. Cytoplasm has course, sparse granules |
| describe monocytes | kidney shaped nucleus, has abundant cytoplasm (stains grey-blue) |
| Blood pathology where there is abnormal increas in the number of WBCs | leukocytes |
| Blood pathology where there is an abnormal increase in the number of RBCs | polycythemia |
| Blood p;athology where there is a condition of too few RBCs or of RBCs with hemoglobin deficiencies | anemia |
| Blood pathology where there is a decrease in the number of WBCs | leukopenia |
| Define hematocrit | packed cell volume (PVC)% occupied by erythrocytes |
| If you had a high hematocrit, would you expect your hemoglobin determination to be high or low? | High. The more erythrocytes you have means you will have more hemoglobin needed for oxygen bonding. |
| If you blood clumped with both anti-A and anti-B sera, your ABO blood type would be ? | AB blood type |
| To what ABO blood groups could to give blood? | AB blood type |
| From which AO donor types could you receive blood? | all donor types |
| Which ABO blood type is most common? | O blood type |
| Which ABO blood type is least common? | AB type |
| What blood type is considered the universal donor? | O blood type. Because they can give blood to the other ABO blood types without causing an ABO transfusion reaction |
| Explain why an Rh-negative person does not have a transfusion reaction on the first exposure to RH-positive blood but does have a reaction on the second exposure | RH antigens of donor sensitizes the recipient on the first time, the 2nd time it doesn't sensitize and a reaction will occur |
| What happens when an ABO blood type is mismatched for the first time? | antibodies bind together causing blood to clump up, and the blood will not work properly. |
