| Question | Answer |
| What ion's concentration gradient is responsible for maintaining resting membrane potential | potassium |
| animal without a respiratory system | jelly fish, hydra, anything with a wall less than a mm wide |
| space inside hydra | Gastrovascular cavity (body cavity) |
| what are the three components neccessary for most excretory systems | filtration reabsorption secretion |
| what excretory system does not utilize filtration? | maphesian tubules of insects. all removal of waste and ions is through active transport |
| annelids have ____type of excretory system | metanephrydia |
| Nephron | Basic functional unit of the kidney. |
| Nephritis | inflammation of the nephron. |
| bowman's capsule | where all filtration of the blood occurs (nephron) |
| PCT (Proximal Convoluted Tubule) | twisty tubule close to the bowman's capsule (connected) In cortex of kidney |
| Loop of Henle | In the medulla. 2 parts: descending and ascending limbs |
| DCT Distil Convoluted Tubule | in cortex. far from bowman's capsule, connects to ascending limb of Loop of Henle, and to the collecting duct |
| vasa recta | absolutely straight capillaries that run along and across the Loop of Henle. part of the peri-tubular capillaries. |
| Peri-tubular capillaries | capillaries that run all along and across the tubule running from the bowman's capsule |
| Glomerular filtration rate (GFR) | rate of filtrate production. the amount of blood filtered per unit time (min). |
| Acedosis | When your blood pH drops too low |
| Acidosis (compensatory mechanisms | increased respiration secretion of hydrogen ions (instead of potassium) re-absorbtion of bicarbonate |
| urea | how we get rid of nitrogenous waste. we convert ammonia into this |
