| During inspiration the diaphragm ___ and the intercostal muscles ____ | Contracts, Contract |
| What is the role of aldosterone in the renal system? | Aldosterone is a hormone that regulates sodium and potassium balance by increasing sodium reabsorption and potassium secretion in the kidneys |
| Hemeostasis | The maintenance of a relatively stable interal environment despite external changes, achieved through regulatory mechanisms that adjust physiological processes |
