Structure
The outermost portion of the kidney
What is the renal cortex
The name for the liquid carrying substances(such as toxins, urea, water, and mineral salts) removed from the blood by the kidneys
What is filtrate
Urine is stored in this part of the body
What is the bladder
Pumping salt into the renal medulla makes it salty, or in science terms, __________
What is hypertonic
The type of transport occurring in the Loop of Henle to move salt into the renal medulla
Active Transport
The inner, darker portion of the kidney
What is the renal medulla
The cup-shaped capsule that surrounds a tight ball of capillaries that retains cells and large molecules in the blood and passes wastes dissolved in water through the nephron
What is the Bowman's capsule
Urine exits the body through this tube
What is the urethra
Which part or parts of the nephron cross into the renal medulla?
Loop of Henle and Collecting Duct
This part of the Loop of Henle is responsible for water reabsorption
What is the Descending Loop
Funnel-shaped structure in the very center of the kidney
What is the renal pelvis
The fine network of capillaries within the capsule at the beginning of the nephron
What is a glomerulus
The area of the kidney where all urine from several renal tubules ends up.
What is the collecting duct
What is the reason capillaries wind around the nephron?
To increase surface area for reabsorption
ADH is secreted in response to ________
Low Blood Volume
The tubes carrying urine from the kidney to the bladder
What are ureters
Each kidney consists of more than ______________ nephrons
What is a million
The name of the waste product produced from the livers breaking down proteins and amino acids
What is urea
We reabsorb almost 100% of these two things in the proximal tubule
What are glucose and amino acids
ADH increases reabsorption of water by doing what?
Increasing aquaporin on cell membranes
Funnel-shaped structure in the very center of the kidney
What is the renal pelvis
The part of the nephron connecting Bowman's capsule and the Loop of Henle
What is the proximal tubule
The skin helps us to excrete these three things
water, salt, and a small amount of urea
Roughly the amount of sodium reabsorbed in the proximal convoluted tubule
What is 65%
This is responsible for sending ADH to the kindey
Pituitary Gland
