Unit 15 Vocabulary Pre-Assessment

abnormal accumulation of fluid in the abdomen

chemical or chemical system that minimizes changes in pH by releasing or binding to hydrogen ions

fluid outside the cells; includes intravascular and interstitial fluids

The first step in urine formation in which substances in blood pass through the filtration membrane and the filtrate enters the proximal convoluted tubule of the nephron.

A ball of capillaries surrounded by Bowman's capsule in the nephron and serving as the site of filtration in the vertebrate kidney.

inability to control bladder and/or bowels

fluid within the cell; synonym for cellular fluid

The cells of the distal tubule at the juxtaglomerular apparatus. They are receptors that monitor filtrate osmolarity as a means of regulatin filtration rate. If a drop is osmolarity is sensed, the macula densa dilates the afferent arteriole (to increase the blood pressure in the glomerulus and thus increase filtration) and stimulates the juxtaglomerular cells to secrete renin (to raise systemic blood pressure).

process of urination

structural and functional unit of the kidney

buffers pH of ICF and urine

chemicals used by body to prevent large changes in the pH of a body fluid during biological processes

These cells form a porous membrane surrounding the endothelial cells of the glomerulus.

acts inside & outside the cell; binds with acids & bases to neutralize them

system of hormones that regulates blood pressure and fluid balance
