Filtration

process by which fluid from the blood filters into Bowman's capsule in the kidneys

Absorption

The process by which nutrient molecules pass through the wall of your digestive system into your blood

Secretion

occurs in the kidneys, it the discharge of wastes from the blood into the filtrate from the nephron tubules.

Bowman's capsule

cup-shaped strucutre of the nephron of a kidney which encloses the glomerulus and which filtration takes place.

Ascending loop of Henle

Portion of the nephron not permeable to water. A filtrate flows up the ascending limp through decreasing concentration of the interstitial fluid, Na+ is actively pumped out of the filtrate, decreasing filtrate concentration.

Descending loop of Henle

Portion of the nephron permeable only to water. The filtrate becomes more concentrated as water is reabsorbed while traveling through the descending limb due to the increasing concentration of the interstitial fluid, drawing water out.

Proximal convoluted tubule

first section of the renal tubule that the blood flows through; reabsorption of water, ions, and all organic nutrients

Distal convoluted tubule

Between the loop of Henle and the collecting duct; Selective reabsorption and secretion occur here, most notably to regulate reabsorption of water and sodium

ADH

Antidiuretic hormone, is secreted by the posterior pituitary gland - and also by nerve endings in the hypothalamus

ANH

Atrial Natriuretic Hormone, is secreted by the atria of the heart, this hormone lowers blood pressure by increasing the excretion of sodium and water by the kidneys

aldosterone

a corticosteroid hormone that is secreted by the cortex of the adrenal gland, "salt-retaining hormone" which promotes the retention of Na+ by the kidneys. na+ retention promotes water retention, which promotes a higher blood volume and pressure

Renal filtrate

the fluid formed from blood plasma by the process of filtration in the renal corpuscles; flows from bowmans capsuled through the renal tubules where most is reabsorbed; the filtrate that enters the renal pervis is called urine

Tubular reabsorption

moves useful substances back into the blood while keeping waste products in the nephron to be eliminated in the urine.

kidney

either of two bean-shaped excretory organs that filter wastes (especially urea) from the blood and excrete them and water in urine, they are located behind the abdominal cavity on either side of the backbone in the lumbar region.

urinary system

consisting of the kidneys, ureters, bladder, and urethra, removes wastes from the blood and helps to maintain water and electrolyte balance

lithiasis

presence or formation of stones

renal tubule*

cup shaped membrane called the Bowman's capsule

renal artery*

where blood enters the kidney through and flows into the nephrons

renal vein*

where the filtered blood containing protein and blood cells leave the kidney and return into the bloodstream through

ureteral orifices *

where urine drains through from the ureters into the bladder

urinate *

urge when bladder fills up with urine and pressure is placed on the base of the urethra

Chronic Kidney Disease*

progressive loss of renal function over months or years (also known as kidney failure)

urinary retention *

inability to completely empty the bladder when attempting to urinate

continuous leaking from the bladder either because it is full or did not empty completely
