Urinary system
functions
| Question | Answer |
|---|---|
| Function | get rid of waste |
| Kidneys | located posterior abdominal wall protected by back fat, redish brown |
| Fibrous capsule | outer layer |
| Renal cortex | the lighter outer region |
| Renal Medulla | forms striped, cone-shaped regions called renal phyramid |
| Sympathetic | nerve stimulation |
| Renal Phyramid | houses the neuphron unit |
| Nephron Unit | makes urine, absorbs water |
| Nephron Unit | takes waste out of blood |
| Nephron Unit | Regulates blood volume, regulate blood pressure |
| Calyx | collects the pee from the Renal Phyramid |
| Renal Pelvis | holding tank |
| Ureter | Connects to the bladder, carries the urine to the bladder |
| Glomerulus | Oxygenated blood |
| Aferent arteriole | going in |
| Efferent arteriole | going out |
| Pentubular Capillery | around the tube capillery |
| Bowmons Capillery | helps exchange nutrients from the glonierulus |
| Tubular secretion | moves small amount of substance from blood to tubules |
| Tubular reabsorption | water and disolved substance move from the tubulus into the blood of peritubular capillaries |
| Glomerular filtrate | water and dissolved substances into Bowmans capsule |
| Glomerular filtration | rate at which glomerular filtration occurs |
| Aldosterone | salt retaining hormone, comes from adrenal cortex |
| Renin angiotensin aldosterone system | end result of this system is to increase blood pressure |
| Juxtaglomerular apparatus | barorecpter, located in the afferent arterioles |
| Juxtaglomerular apparatus | secretes renin when senses low blood pressure |
| Artrial natriuretic peptide | sense high blood pressure |
| Urine | 95% water |
| Clear Urine | drank a lot |
| Urine | sterile |
| Specific gravity | weight of urine |
| Urine | pH-6 |
| Innermost layer of bladder | Mucus |
| Detruser muscle | muscle layer |
| Brain natriuretic peptide | decreases the reabsorption of sodium |
| Brain natriuretic peptide | causes greater excretion of sodium and water by the kidney |
| Antidiuretic Hormone | stimulates the reabsorption of water |
| Parathyroid hormone | stimulates the reabsorption of calcuim and excretion of phosphate |
| Angiotensinogen | Renin activates this to form angiotensin 1 |
| Angiotentensin 1 | secreted by the liver and circulates within the blood |
| Converting enzyme | enzyme which acts to change angiotensin 1 to angiotensin 2 |
| angiotensin 2 | stimulates the adrenal cortex to release aldosterone |
| Aldosterone | stimulates the distal tube to reabsorb sodium and water and to excrete potassium |
| collecting duct | ADH likes to work here |
| Secretion | out |
| Absorption | In |
| Adrenal Cortex | Stimulates Aldosterone |
| Distal Tubular | reabsorb sodium |
| ADH | Takes out |
| Diaretic | makes you pee |
| Mucus | lines the organs |
| two | kidneys |
| two | ureters |
| one | bladder |
| one | urethra |
