(34 cards)

Creatine

Front

-100% is eliminated -derived from creatine phosphate is muscle tissue

Back

CsHP

Front

created by the filtrate that opposes the GHP =15mmHg

Back

reabsorption

Front

removal of water and solutes from the filtrate back into the blood (reclaimed)

Back

afferent arteriole

Front

-blood enters glomerulus -bigger than efferent

Back

active transport

Front

the movement of materials through a cell membrane using energy (ATP)

Back

GHP

Front

-created by HP (left ventricle) =60mmHg

Back

ALH

Front

-thick -water stays in and diltutes

Back

renal corpuscle

Front

glomerulus and bowman's capsule

Back

renal tubule

Front

- urine is formed after filtration -DCT, loop of henle, PCT

Back

DLH

Front

-thin, simple squamous -water leaves and concentrates

Back

facilitated diffusion

Front

molecules pass across the membrane through cell membrane channels

Back

Kidney location

Front

-retroperitoneal- behind the parietal peritoneum -attaches onto the dorsal body wall, held there by adipose capsules

Back

Urinary function: excretion

Front

Removes organic waste products from the bodily fluids and discharges them from the body

Back

cotransport

Front

the active transport of a solute indirectly drives transport of other substances

Back

Hilus

Front

indentation where blood vessles enter enter the kidney

Back

Function: Regulation

Front

Homeostatic regulation of blood plasma 1. Blood volume 2. Ion concentration (sodium, glucose) 3. pH (removes hydrogen ions) 4. Conserves nutrients

Back

Uric acid

Front

-breakdown of nucleic acids -Crystallizes because it is insoluble

Back

Nephron parts

Front

renal corpuscle and renal tubule

Back

GFR

Front

-amount of filtrate produced in both kidneys in one minute =155mL

Back

Nephrons in the medulla

Front

-juxtamedullary, make up 15% - contribute to the concentration gradient needed to produce low volumes of urine - has longer loops with vasa recta

Back

Nephrons in the cortex

Front

-cortical, make up 85% -superficial

Back

Blood supply of kidneys

Front

Renal artery - segmental artery - interlobar artery - arcuate artery - interlobular artery - afferent arteriole - glomerulus- efferent arteriole-peritubular capillaries- venules- interlobular V- arcuate V- interlobar V- renal V

Back

renal papilla

Front

-apex of renal pyramid -drain urine into the uterus

Back

Filtration

Front

-water and solutes move acorss the glomerulus capillaries into the capsular space - HP is the driving force behind it

Back

renal pyramids

Front

bundles of collecting ducts NOT a part of the nehpron

Back

podocytes

Front

cells that project into the capsular space and wrap around the capillaries forming filtration slits

Back

efferent arteriole

Front

-small artery that carries blood away from the capillaries of the glomerulus - attaches to peritubular capillaries

Back

Glomerulus

Front

a group of capillaries in the renal corpuscle

Back

Urea

Front

-60-90% of nitrogenous material - Made in the liver- ammonia+CO2

Back

Urine flow

Front

renal papillae, minor calyx, major calyx, renal pelvis, ureter

Back

BCOP

Front

-opposes the GHP - proteins that are too big go through this =28mmHg

Back

Secretion

Front

transports solutes from blood into the tubular fluid

Back

counter transport

Front

one substance is transported in one direction at the same time as another substance is being cotransported in the other direction.

Back

regulation of GFR

Front

-local auto regulation -hormones (ADH, aldosterone AG2) -autonomic regualtion

Back
