What do the kidneys filter
filter metabolic wastes, excess ions and chemicals
from the blood to form urine
Where are the kidneys
retro-peritoneal
layers of Kd from in to out
cortex medulla pelvis ureter
Glomerial capsule
Filtration
Proximal convoluted tubule
Reabsorption and secretion
Loop of henle
Reabsorption and concentration of urine
distal convoluted tubule
Secretion and reabsorption
collecting duct
reabsorption
Ureter
Exctretion from collecting duct
Filtrate contents
- mainly water
- Na, Cl, K, HCO3-
- glucose
- amino acids
- creatinine
- urea
Primary sex organs
testes
ovaries
Accessory sex organs
glands
external genitalia
Sperm made in
Testes
Sperm matures in
epididymis
Prostate location
All around urethra at base of bladder
Seminal vesicle location
Lie on the posterior surface of the urinary bladder
Seminal vesicle Secrete about ___% of the volume of semen
60
Seminal vesicle fluid contains
- fructose to nourish sperm
- substances to enhance sperm motility
- prostaglandins
- immunosuppressant substances (to stop the ladies immune response)
- enzymes that clot and then liquify the semen
Cremaster muscles function
wraps around testes and drops and raises testes for temp control
dense pampiniform venous plexus
- in the spermatid cord
- helps to cool arterial blood before it enters the testis
testes
site of spermatogenesis
