| Question | Answer |
|---|---|
| What is the pH range of our blood?What is it considered on the scale? | 7.35 - 7.45; basic |
| What is hematocrit? | Percent of blood (erythrocytes) |
| What part of a red blood cell binds and transports oxygen? | Hemoglobin |
| In leukocytosis, what is the WBC count? | Over 11k per mm3 |
| What is anemia? | Decrease in oxygen carrying ability of blood |
| What is diapedesis? | Ability to move in/out of blood vessels |
| Low levels of WBCs causes a condition called what? | Leukopenia |
| What are granulocytes? | A type of leukocyte that has granules |
| Platelets are fragments of megakaryocytes. What are megakaryocytes? | Mulinucleate cells |
| What hormone controls the rate of erthrocyte production? | Erythroprotein |
| What is plasma considered? | Nonliving fluid matrix |
| When blood is centrifuged, how do the layers of blood stack from the top to the bottom? | Plasma 55% Buffy <1% RBC 45% |
| What part of our blood cells transports oxygen? | Hemoglobin |
| What formed element is most abundant in blood? | Erythrocytes |
| What do erythrocytes lack? | Mitochondria, nucleus/organelles |
| What are the 2 major groups of WBCs | Granulocytes, agranulocytes |
| Which cells are granulocytes? Agranulocytes? | G: neutrophils, eosinophils, basophils A: lymphocytes, monocytes |
| Which granulocytes releases histamine | Basophils |
| What is the most numerous WBC | Neutrophils |
| What do eosinophils do | Kill parasitic worms, allergy attacks |
| Where does hematopoiesis occur | Red bone marrow |
| What stem cell gives rise to all formed elements | Hemocytoblast |
| How long does a RBC survive? | 100-120 days |
| What is polycythemia | Disorder from excessive/increase of RBCs due to altitude or cancer |
| What is hemostasis | Stopping bleeding results from break in blood cell |
| What long, hair like molecules form the basis of a clot during coagulation | fibrin |
| What is hemophilia | Hereditary bleeding disorder |
| What is the sequence, in order of hemostasis | Vascular spasms, platelet plug formation, coagulation |
| What is heparin | Anticoagulant, prevents fast clotting |
| How long does it take blood to clot | 3-6 min |
| What is a thrombus | A clot in an unbroken blood vessel |
| What percent of blood loss can cause shock and can be fatal | 30 |
| Blood type that forms anti-a and anti-b antibodies | O |
| Blood type that doesn't form a or b antibodies | AB |
| Blood type with no antigens | O |
| Blood type that can receive B and AB | AB |
| Blood type that posses A antigen only | A |
| Universal recipient | AB |
| What are antigens | Substances body recognizes as foreign |
| When antibodies bind to antigens on foreign types, clumping or ____ can occur | agglutination |
| If you carry Rh antigen what are you | Rh+ |
| What does blood transport | Nutrients, wastes, hormones, body heat |
| What is blood | Only fluid tissue Connective |
| Components of blood | Formed elements (living cells), plasma (nonliving fluid matrix) |
| Blood temperature | 38C or 100.4F |
| Blood volume | 5-6 liters or 6 quarts 8% body weight |
| What is plasma made of | 90% water |
| Plasma proteins | Most abundant, made by liver Albumin - blood buffer contributes to osmotic pressure Clotting proteins antibodies - pathogens |
| What does plasma help | distribute body heat |
| RBCs, WBCs names | Erythrocytes Leukocytes |
| How do RBCs differ | No nucleus, few organelles |
| Leukopenia | Low WBC count |
| Granulocytes cells functions | Neutrophils - most numerous, phagocytes at active sites of infection Eosinophils - kill parasitic worms, allergy attacks Basophils - heparin, decrease clotting |
| List of WBCS most to least abundant | Neutrophils, lymphocytes, monocytes, eosinophils, basophils Never let monkeys eat bananas |
| Lymphocytes | immune response |
| Monocytes | macrophages when they migrate into tissues |
| Platelets | clotting process |
| Hematopoiesis | process of blood cell formation |
| Thrombocytopenia | Insufficient platelets, suppresses bone marrow, small movements cause bleeding |
