whats the nephron
functional unit of the kidney where urine is formed
order of the nephron
glomerulus
Bowman’s capsule
proximal tube
loop of Henle
distal tube
collector tube
the upper part of the nephron
cortex
the inferior part of the nephron
medulla
the first part of the nephron
corpsule
the second part of the nephron
renal tubes
urine formation-first step
filtration
glomerulus to Bowman’s capsule
blood gets filtered
urine formation-second step
reabsorption
proximal tube to the loop of Henle
recover solutes
proximal tube: glucose
thin loop of Henle: water
thick loop of Henle: NaCI sodium
urine formation-third step
secretion
distal tube
takes from the blood toxic substances, drugs, k+ (potassium)
urine formation-fourth step
concentration
collectors tube
urine is collected here
