The Kidney's (worksheet) Flashcards
excretion?
the process of ridding the body of chemical waste
urea?
a nitrogen-containing waste produced from protein breakdown
kidneys?
one or two organs located in the lower back of humans.
urine?
a liquid waste produced by the kidneys.
ureters?
tubes leading from the kidneys to the urinary bladder.
urethera?
th etube leading from the bladder to the outside of the body
nephrons?
microscopic units in the kidneys that filter the blood.
glomerulus?
a ball of capillaries in the nephrons.
Bowman’s Capsule?
a double walled structure surrounding the glomerulus.
proximal tubule?
part of the nephron closest to Bowman’s capsule.
Henle’s loop?
a u-shaped structure in the nephron.
Distal Tubule?
connects to a large tube called a collecting tubule.
cortes?
the outer protion of the kidney.
medulla?
the central portion of the kidney.
glomerular filtrate?
the fluid tha taccumulates in Bowman’s capsule.
antidiuretic hormone?
regulates the reabsorption of water.
diuresis?
the production of large volumes of urine.
hemodialysis?
artificial filtering of the blood.
What is the function of the golmerulus and the bowman’s capsule?
glomerulus-bed of capillaries located within the bowman’s capsule that delivers blood to the nephron to be filtered out
What is the function of the loop of henle?
reabsorption of water
compare the processes of the distal tubule adn the proximal tubule?
proximal-nutrients are resabsorbed into the blood.
distal- waste products are secreted back into the tubule
trace the floow of blood through the nephron
artery–>arteriole–>caillary–>venule–>vein
trace the flow of filtrate through the nephron t
glomerulus–>bowman’s capsule–>proximal tubule–>loop of henle–>distal tubule–>collecting duc
during secretion in the kidney, substances move from what to what?
blood to filtrate
Organs involved in the excretion process include?
kidneys & lungs
What tube carries urin outside teh body from the bladder?
urethra
what seperates the proximal and distal tubles?
loop of henle
