Urinary system
| Term | Definition |
|---|---|
| Adrenal Glands | a small gland that makes steroid hormones, adrenaline, and noradrenaline |
| Aldosterone | a corticosteroid hormone which stimulates absorption of sodium by the kidneys and so regulates water and salt balance |
| RAAS - Renin Angiotensin-Aldosterone System | is a hormone system that regulates blood pressure, fluid and electrolyte balance, and systemic vascular resistance |
| Antidiuretic Hormone (ADH) | a hormone that helps blood vessels constrict and helps the kidneys control the amount of water and salt in the body. This helps control blood pressure and the amount of urine that is made |
| Excretion | the process by which an organism rid themselves of waste products and of the nitrogenous by-products of metabolism |
| Filtration | the process by which animals rid themselves of waste products and of the nitrogenous by-products of metabolism |
| Glomerular Filtration | a portion of the blood plasma is filtered into the kidneys |
| Kidney | remove wastes and extra fluid from your body |
| Nephron | each nephron has a glomerulus to filter your blood and a tubule that returns needed substances to your blood and pulls out additional wastes |
| Glomerulus | filters your blood |
| Proximal Convoluted Tubule | a segment of the renal tubule responsible for the reabsorption and secretion of various solutes and water |
| Loop of Henle | reabsorb water and sodium chloride from the filtrate |
| Descending Limb | the portion of the renal tubule constituting the first part of the loop of Henle |
| Ascending Limb | the defense of the extracellular fluid volume, the urinary concentrating mechanism, calcium and magnesium homeostasis, bicarbonate and ammonium homeostasis, and urinary protein |
| Distal Convoluted Tubule | regulating extracellular fluid volume and electrolyte homeostasis |
| Collecting Duct | collects urine from the nephrons (cellular structures in the kidney that filter blood and form urine) and moves it into the renal pelvis and ureters |
| Vasa Recta | bring nutrients and oxygen to the medullary nephron segments but, more importantly, they also remove the water and solute that is continuously added to the medullary interstitial by these nephron segments |
| Renal Calyx | chambers of the kidney through which urine passes |
| Major Calyx | from the major calyces, the urine flows into the renal pelvis; and from there, it flows into the ureter |
| Minor Calyx | a minor calyx surrounds the renal papillae of each pyramid and collects urine from that pyramid |
| Renal Pelvis | urine collects here and is funneled into the ureter, the tube that connects the kidney to the bladder |
| Renal Artery | send a large volume of blood to the kidneys every day for filtering |
| Afferent Arteriole | regulation of blood pressure as a part of the tubuloglomerular feedback mechanism |
| Efferent Arteriole | brings filtered blood from the glomerulus to the rest of the kidney and back to the general circulation |
| Renal Vein | carries blood from the kidney and ureter to the inferior vena cava |
| Secretion | he transport of certain molecules out of the blood and into the urine |
| Ureter | carry urine from the kidneys to the bladder |
| Urethra | allows urine to pass outside the body |
| Urinalysis | to detect and manage a wide range of disorders, such as urinary tract infections, kidney disease and diabetes |
| Urinary bladder | serve as a reservoir for urine before it leaves the body |
| Urinary system | to filter blood and create urine as a waste by-product |
| Urine | remove waste products and drugs from the body |
