Circ. and digestive systems
| Question | Answer |
|---|---|
| Emulsify | what bile does to fats |
| Glucagen | Pancreatic, red blood cells |
| Calorie | measures unit of energy |
| Pepsin | Has a low optimum ph |
| Saliva | Begins chemical digestion of food in humans |
| Peristalis | Moves food into the stomac |
| Plasma | Includes water, protein, globulin, hormones |
| Liver | detoxification of of drugs and alcohol, formation of urea |
| Systal | when ventricals contract |
| Arrhythmia | Brady cardia, fibrillation |
| Leukocyte | Blood cells not responsible for gas exchange |
| Diastole | expansion of the lungs |
| Lipids | Fat cells |
| Arteries | carry blood away from the heart. Have thicker, mpre muscular walls than veins |
| Dietary deficiencies that will quickly affect the functioning of enzymes in the human | Lack of essential amino acids |
| Long term effect if the lymphatic vessels assosciated with a capillary bed are blocked | Fluid would accumulate in the interstitials. |
| The Human stomac | 1.Produces both digestive hormones and enzymes. 2. Is lined with mucus for for protection. 3. Has a low PH |
| When a person sits for a long periods of time without moving, fluid may accumulate in the feet and ankles. Whay aspect of the body would generally assist the circulartary system in returning this fluid back to circulation | The move ment of skelectal muscle |
| Which are the follwing is a similarity between open and closed circular system | 1. Some sort of pumping device helps move blood through the body. 2. All tissues come into contact with the circulating "blood" so that exchange can take place |
| An animal that eats nothing but leaves | 1. Broad, flat teeth. 2. A large ceacum 3. ingestion of own feces. |
| HUman essential amino acids | are only obtained from our diets. |
| A deficiency of eesential nutrients niacin (B3) can be compensated for by | Only a diet that contains niacin |
| Blood pressure 120/80 | 120 = systolic pressure |
| SA node | originates the hearts contraction in the artia |
| Ventricles | depend upon the bundle of HIS and Purkinje fibers to coordinate thier contraction |
| caecum | Area of large intestine by appendix |
| Caecum | Most Herbivours have larger Caecum than Carivours |
| A red blood cell in the artery of the left arm | must pass through a minimum of two capillary beds before entering the hearts left ventrical |
| Blood samples taken from an individual who has not eaten in 24 hours. | would be expected to have high level of glucagon and low levels of insulin. |
| Foods with a low glycemic index | contain fewer calories then those with a high index. |
| Saturated fats | are solid as room temperature because of the double bonds between carbons. |
| The chemical and mechanical breakdown of food into smaller molecules is called | Digestion |
| The contracted stage of the heart cycle is known as the | Systole |
| The tubular digestive system found in most animals is the | alimentary canal. |
| The main oxygen carrying protien in the mammalian blood is | Hemoglobin. |
| Hemoglobin is made of | 4 protien chains and 4 prosthetic groups thet bind oxygen |
| Looking at foods in terms of how they affect the blood sugar level is using thier | Glyceimic index |
| Glucagon, insulin and gastrin are all hormones involved | in nutrition and digestion in humans. |
| The pulmenary circuit of circulation | is the one that is reposible for oxygenation of the blood |
| Fibron | is the protien that makes up the mesh that traps blood cells and forms a clot |
| Thrembosis | A clot coagulation of blood that causes blockage in a blood vessel |
| sphincter muscles | regulate the movement of material through the digestive system |
| Chyme | produced in the stomac |
| The liver synthesis | Bile from cholestrial |
| Gall bladder | Stores bile which aids in digesting lipids |
| Pancreas produces | digestive enzymes and bicorbonate solution. |
| Duodenum | Digestion |
| jeunum and ileum | Absorption |
