| Question | Answer |
|---|---|
| 3 main plasma proteins | fibrinogen, globulins, albumin |
| fibrinogen | plasma protein for clotting |
| globulin | plasma protein for antibodies |
| albumin | plasma protein for blood viscosity, most abundant plasma protein |
| Organ that makes plasma proteins | Liver |
| organ that makes thrombopoetin | liver |
| function of thrombopoetin | stimulates platelet production |
| EPO | made by kidney, stimulates RBC production |
| average blood volume in an adult | 5L |
| RBC transports O2 via... | the "hem" portion of hemoglobin, binds to iron |
| megakaryocyte | fragments into a platelet (thrombocyte) |
| 3 types of lymphocytes | B-cell, T-cell, NK (Natural Killer) |
| B-cell | Binds to soluble antigens and break them into fragments via endocytosis |
| T-Cells | cell mediated, |
| What type of cell determines blood type and why | RBC - proteins on surface |
| Valve between left atria & Left Ventricle | Bicuspid/Mitral |
| When ventricles contract... | valves close to prevent backflow of blood |
| SA node | pacemaker of the heart |
| SA node location | Upper Right atria |
| Contraction | Systole |
| stretch heart first & it will contract with greater force (ie fill it to capacity) | Starlings law of the heart |
| Epinephrine | sympathetic neurotransmitter that increases heartrate |
| ACH | Parasympathetic neurotransmitter that slows heartbeat |
| Starlings Law of Capillaries | Arteriole end filters, venous end reabsorbs nearly equally, rest is picked up by lymphatic system and back to CV system |
| R. lympantic vessel and left thoracic duct dump into which vessel | Subclavian vein |
| 2 ways to effect resistance to blood flow | viscosity of blood & diameter of tube |
| viscosity of blood | slows blood flow, BP goes up, heart pumps harder |
| diameter of vessels | smaller diameter = slower flow = higher BP = heart works harder |
| Barrow receptors | stretch receptors in arteries |
| Cardiovascular center located in... | Medulla Oblongata |
| Barrow receptors send signals to... | Cardiovascular center of brain |
| primary lymph organs | Thymus & Bone marrow |
| Secondary lymph organs | spleen, lymph nodes, pyers patches |
| pyers patches | in sm. intestines |
| cell infected by virus secrets... | interferon |
| interferon | secreted by infected cell to protect cells around it |
| B cell changes to a ... and makes ... | plasma cell / antibodies |
| Antibodies most effective to... | body fluids - blood, lymph |
| Killer T Cells | effective on intracellular viruses and bacteria / destroys cells |
| opsinization | coating cells with antibody to attract phagocytic cells |
| as the diaphragm contracts | chest cavity expands & pressure drops causing air to rush in - inhalation |
| most of CO2 transported in blood as... | bicarbs in plasma |
| 2ndary transport of CO2 on ... | globin |
| accessory organs of digestion | liver, pancreas, gallbladder |
| cephalic phase of digestion | thinking, seeing, smelling, tasting, |
| pepsin | digests protein |
| amalyase | digests starch |
| lipase | digests fat |
| protein waste product | amonia |
| Amonia converted to... | urea & shipped to kidney |
| most nutrients absorbed in... | sm. intestine |
| lg intestine absorbs... | water |
| functional unit of kidney | nephron |
| renal corpuscle | bowmans capsule & glomulerulus |
| aldosterone | causes kidney tubules to be more permiable to sodium - raises BP, raises blood volume, potassium out |
| ADH | makes kidney tubules more permiable to water |
| 1-2 Litres | urine output per day |
| filtrate | filtered blood |
| filtrate contains everything but | protein, RBC & WBC |
| muscularis | musclular wall of the GI tract |
| peristalsis | pushes food thru tube |
| segmentation | mixes chyme & digestive juices in Sm. Intestines |
| Haustration | in colon, Haustras |
| Primary digestion in stomach | protein - because of the acid environment |
| gallstones made of... | chrystalized cholesterol |
| action of bile | emulsify fats |
| chyme | liquid stomach contents |
| transport fat | lymphatic system |
| lacteals | lympahtic capillaries in sm. intestines |
