SLS Bio12 Urinary
| Term | Definition |
|---|---|
| Anti-Diuretic Hormones | A hormone secreted by the posterior lobe of the pituitary gland that constricts blood vessels, raises blood pressure, and reduces excretion of urine |
| adrenal cortex | the cortex of the adrenal gland; secretes corticosterone and sex hormones |
| afferent arteriole | The afferent arterioles are a group of blood vessels that supply the nephrons in many excretory systems |
| aldosterone | a corticosteroid hormone that stimulates absorption of sodium by the kidneys and so regulates water and salt balance. |
| bowman's capsule | a capsule-shaped membranous structure surrounding the glomerulus of each nephron in the kidneys of mammals that extracts wastes, excess salts, and water from the blood. |
| collecting duct | The collecting duct system of the kidney consists of a series of tubules and ducts that connect the nephrons to the ureter |
| glomerulus | a cluster of capillaries around the end of a kidney tubule, where waste products are filtered from the blood |
| homeostasis | the tendency toward a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes. |
| hypothalamus | a region of the forebrain below the thalamus that coordinates both the autonomic nervous system and the activity of the pituitary, controlling body temperature, thirst, hunger, and other homeostatic systems, and involved in sleep and emotional activity. |
| kidney | each of a pair of organs in the abdominal cavity of mammals, birds, and reptiles, excreting urine |
| loop of henle | the part of a kidney tubule that forms a long loop in the medulla of the kidney, from which water and salts are resorbed into the blood. |
| metabolic waste | Metabolic wastes or excretes are substances left over from excretory processes, which cannot be used by the organism, and must therefore be excreted. |
| nephron | each of the functional units in the kidney, consisting of a glomerulus and its associated tubule, through which the glomerular filtrate passes before emerging as urine |
| nitrogenous waste | Urine is a typically sterile liquid by-product of the body secreted by the kidneys through a process called urination and excreted through the urethra |
| osmotic gradient | Osmosis is the spontaneous net movement of solvent molecules through a partially permeable membrane into a region of higher solute concentration, in the direction that tends to equalize the solute concentrations on the two sides |
| peritubular capillary network | In the renal system, peritubular capillaries are tiny blood vessels that travel alongside nephrons allowing reabsorption and secretion between blood and the inner lumen of the nephron |
| posterior pituitary | the posterior lobe of the pituitary body; primarily glandular in nature |
| pressure filtration | the filtrate that passes from the lumen of the glomerular capillary to the space of Bowman's capsule. |
| proximal convoluted tubes | The proximal tubule is the portion of the duct system of the nephron of the kidney which leads from Bowman's capsule to the loop of Henle. |
| distal convoluted tubes | The distal convoluted tubule is a portion of kidney nephron between the loop of Henle and the collecting duct system. |
| re-absorption of water | the act or process of absorbing again, as the absorption by the kidneys of substances |
| renal cortex | the cortex of the kidney containing the glomeruli and the convoluted tubules |
| renal medulla | The renal medulla is the innermost part of the kidney. The renal medulla is split up into a number of sections, known as the renal pyramids. |
| renal pelvis | the broadened top part of the ureter into which the kidney tubules drain. |
| selective reabsorption | Selective reabsorption |
| tubular excretion | In physiology, reabsorption or tubular reabsorption is the flow of glomerular filtrate from the proximal tubule of the nephron into the peritubular capillaries, or from the urine into the blood |
| urea | a colorless crystalline compound that is the main nitrogenous breakdown product of protein metabolism in mammals and is excreted in urine. |
| ureter | the duct by which urine passes from the kidney to the bladder or cloaca. |
| urethra | the duct by which urine is conveyed out of the body from the bladder, and which in male vertebrates also conveys semen. |
| urinary bladder | a membranous sac for temporary retention of urine |
| urine | a watery, typically yellowish fluid stored in the bladder and discharged through the urethra. |
| efferent arteriole | The efferent arterioles are blood vessels that are part of the urinary tract of organisms. The efferent arterioles form from a convergence of the capillaries of the glomerulus |
