Name: Micturition, Other Organs of Excretion and Kidney Disorders
Author: StemPy Lab

How urine leaves the body, what it holds and what a change in it can tell a doctor. The lungs, liver, skin and glands that also excrete, the balance of water in a day, and the disorders of the kidney: uraemia, kidney stones and glomerulonephritis, with dialysis and transplant.

Lesson 1about 25 min
Micturition and the nature of urine
Urine from the nephrons runs through the ureters into the bladder, where it is stored until a voluntary signal from the brain empties it. This lesson explains the micturition reflex and what the colour, the volume and the contents of urine can tell a doctor.

Lesson 2about 25 min
Other organs of excretion and the water balance
The kidneys are not the only organs that excrete. The lungs remove carbon dioxide and water, the liver passes bile pigments into the gut, the sweat and sebaceous glands remove salts and oily wastes, and the saliva has a little nitrogen. This lesson lists them, and adds up the water that the body gains and loses in a day.

Lesson 3about 30 min
Kidney disorders, dialysis and transplant
When the kidneys fail, urea builds up in the blood. This lesson covers uraemia, kidney failure, kidney stones and the inflammation of the glomeruli, then shows how haemodialysis cleans the blood and why a transplant is the lasting treatment.
