Urin/Endo Sys
| Question | Answer |
|---|---|
| Na+ reabsorption is controlled by adrenal gland | F |
| Electrolytes control water movement between body compartments | T |
| ISF is extracellular | T |
| Filt. & Reabsorp move substances in opposite directions in the nephrons | T |
| Calcium is most abundant mineral in body | T |
| Aldosterone and ADH do the same thing | F |
| A person taking diuretics forms a more concentrated urine | T |
| ADH decreases permeability of collecting ducts | F |
| K+ is most abundant intercellular ion | F |
| ADH is antagonistic to ANP | F |
| The afferent arteriole of the Glom. is smaller than the efferent, which creates filtration pressure | F |
| Albumin and other plasma proteins help maintain blood osmolarity | T |
| Juxta. nephrons are responsible for creating more concentrated urine, while Cortical nephrons make more dilute urine | T |
| H20 follows NA+ | T |
| ADH reg. sodium levels in the blood and urine | F |
| The PCT contains the Jux. App. | F |
| Aquaporins are inserted the cells of collecting ducts, when ADH is secreted | T |
| Cells of PCT have ADH receptors | F |
| Aldosterone indirectly effects chlorine levels | T |
| Renin is produced by the LV | F |
| Angiotensin is secreted by KD | F |
| There is more K+ outside of cells and more negative proteins inside of cells | F |
| H+ levels are controlled by KD and LU | T |
| Podocytes are part of the nephron | T |
| Buffers balance extremes in pH by absorbing OH- or releasing HCO3 | F |
| CO2 + H20 --> H+ & HCO3 | T |
| H+ and HCO3 --> H2CO3 --> CO2 + H20 | T |
| Cortisol increases blood glucose | T |
| Nor-E also increase blood glucose levels | T |
| Insulin increases blood glucose levels | F |
| Calcitrol is released by Thyroid | F |
| Mineralcortocoids are produced by same gland that synth. cortisol | T |
| ADH is a mineralcortocoid | F |
| ADH was formerly known as Vasopressin, bc it vasoconstricts | T |
| The hypothalamus produces ADH | T |
| BOth PTH and Calcitrol increase blood calcium levels | T |
| Angiotensin-2 is the same as vasopressin | F |
| The thryoid gland is under control of a Tropic hormone | T |
| The posterior pituitary secretes ADH and Oxytocin | T |
| Angiotensin-2 targets the Adrenal cortex, as well as blood vessel walls | T |
| Gulcagon promotes increase in blood sugar levels | T |
| The HT has an endocrine fxn bc it produces ANP | T |
| The pancreas secretes: | Insulin (glucose in blood down) and Glucagon (glucose in blood up) |
| The Heart produces ______ and it determines the amount of ______ excreted by KD | ANP, Sodium |
| The Parathyroid produces: | PTH (increase calcium in blood) |
| The Adrenal glands make ________ and it is produced in response to ________, it also increases blood glucose levels | Cortisol, Stress |
| Produced by Adrenal cortex, _________ regulates reabsorption of _______ and release of ____________ | Aldosterone, rebsorption of Sodium, Excretion of Potassium *** overall affect of increasing blood volume / BP |
| Produced by Kidneys, ______ promotes _________ reabsorption, increasing bone ________ | Calcitrol, Calcium, Calcium |
| This hormone increases blood calcium | PTH |
| The hormone determines how much H20 should be released or reabsorped | ADH |
| This hormone cz uterine contractions | Oxytocin (OT) |
| Two hormones that are stored and released by Post. Pit are: | OT and ADH |
| Fxns of KD | Reg. blood pH, Reg. BP, Maintain calcium homeostasis, help with RBC synth, Maintain glucose levels, maintain blood composition, maintain blood volume |
| 5 Main portions of nephron are: | Glomerular Capsule (GC), PCT, LOH, DCT, CD |
