Urinary Flashcards
The functional unit of the kidney
Nephron
A cluster of capillaries responsible for glomerular filtration.
Glomerulus
Filters small, nonionized, non protein bound molecules through bowman’s capsule to glomererclar filtrate in lumen of tubules
Glomerular filtration
Responsible for tea sorbitol and secretion of dissolved substances and water
Tubules
Where are substances needed by the body absorbed from?
From filtrates
Where do substances that are reabsorbed go?
Into the plasma through the capillaries
Where are extra substances excreted?
In urine
What does tubule secretion help maintain?
Blood pH and excreting drugs
Why do we do to drug doses in renal complication animals?
Lower due to lack of ability to excrete
What do diuretic urinary drugs do?
Increase urine volume produced by kidneys by increasing plume of water released by body tissue
Diuretic type that acts through renal tubules to block sodium reabsorption.
Thiazine diuretic
Diuretic type that block reabsorption of Cl, K, Ca, H, Mg at the loop of Henle.
Loop diuretics
Lasix® generic name and type of diuretic.
Furosemide- Loop diuretic
Diuretic that act on distal convoluted tubules
Potassium sparing diuretics
Six features of the urinary systems
Two kidneys, two ureters, one bladder, one urethra
This type of diuretic promotes water and sodium excretion through Na-K pump interference
Potassium sparing diuretics
Type of diuretic that was used to decrease intraoccular pressure with open angle glaucoma by blocking cation of the enzyme carbonic anhydrase.
Carbonic anhydrase diuretic
Diuretic type that increases concentration of renal tubule filtrate
Osmotic diuretics
Higher than normal blood pressure.
Hypertension
Promote Na and water loss which decrease pressure to help decrease hypertension.
Diuretics
Enalapril trade name.
Enacard®
Benazepril trade name.
Lotensin
Captopril trade name.
Capoten
Type of anti hypertension drug Blocks calcium influx to help smooth muscle contraction to reduce blood pressure.
Calcium channel blockers
