How many kidneys do we have?
Two.
I go from the urinary bladder to the outside world.
What is the Urethra?
What does homeostasis mean?
Balance.
Blood is under high pressure here and toxins are pushed out of the blood to become filtrates.
What are the glomerulus and bowman's capsule?
involuntary loss of urine
incontinence
What are the functional (working) units of the kidneys?
The nephrons.
We carry urine from the kidneys to the urinary bladder.
What are the ureters?
the maintenance of the appropriate balance of water and salt
osmoregulation
This is where salt and water are reabsorbed.
What is the loop of Henle?
When a substance moves from an area of high concentration to an area of low concentration.
diffusion?
What are the four functions of the urinary system?
getting rid of wastes, osmoregulation, maintaining acid-base balance, and secretion of hormones
I can hold up to 500 mL of urine before it passes through to the urethra.
What is the urinary bladder?
What are the three things the kidneys regulate?
The kidneys regulate water balance,electrolytes and the PH of blood.
this is where hydrogen ions are secreted or reaborbed.
What is the distal convoluted tubule?
kidney's filtration unit
nephron
What shape is the kidney?
The shape of a kidney bean.
I connect the proximal convoluted tubule and the distal convoluted tubule in mammals and birds.
What is the loop of Henle?
this hormone is produced in the kidneys and liver and stimulates red blood cell production in the bone marrow when oxygen in the tissue cells is low
erythropoietin
This is where water balance takes place-the last chance before it exits the body as urine.
What is the collecting duct?
We are the three main parts of the kidney.
What are the medulla, the cortex, and the renal pelvis?
depression found on the concave side of each kidney
hilum
I encapsulate (surround) the glomerulus and catch the filtrates that are pushed out of blood.
What is the Bowman's capsule?
this vitamin acts as a hormone by regulating the amount of calcium and phosphorus in the blood
vitamin D
This is where glucose (sugar) and water are reabsorbed and become filtrate.
What is the proximal convoluted tubule?
These muscles must relax in order for you to release urine from your urinary bladder and urinate.
What are the sphincters?
