the urinary system secretes
urine
the digestive system secretes
stool waste
the respiratory system secretes
CO2
the integumentary system secretes
sweat
how does urine move from the kidneys to the bladder
two ureters
what fibrous connective tissue surrounds the kidneys
renal capsule
trigone
triangular-shaped region in the floor of the bladder
organs of the urinary system
- kidneys
- ureters
- urinary bladder
- urethra
- meatus
enlarged portion of the nephron that surrounds the glomerulus
Bowman capsule
small blood vessel that supplies the glomerulus with blood
afferent arteriole
controls water reabsorption
Anti-diuretic Hormone (ADH)
- promotes reabsorption of Na+
- produced in adrenal cortex
- adrenal steroid
aldesterone
where is the thirst center located
hypothalamus
what abdominal organ controls salt excersion
kidneys
intracellular
in-between
extracellular
outside
- movement of molecules in and out of a cell from Low to High
- requires energy
active transport
- movement of solutes from High to Low
- does not require energy
diffusion
- movement of water through a semi-permeable membrane
- high to low movement
osmosis
nitrogenous waste product
urea
what is the specific gravity of urine
- the amount of dissolved substances in urine
- 1.002 (dilute) - 1.040 (concentrated)
- movement of materials under pressure
- glomerulus –> glomerular capsule
glomerular filtration
what happens between the glomerulus and the bowman capsule
nephron’s filtering device
the small coiled tube that creates urine
nephron
