Changes in blood volume and concentration are detected in the brain cells in the:

Water and mineral ion levels
Can u live without a kidney?
Technically yes!
No way!
If you are dehydrated (low water potential in the blood), the body must conserve water. To do so, the brain triggers the pituitary gland to ...
release MORE ADH, making the collecting duct MORE permeable
release LESS ADH, making the collecting duct LESS permeable
release MORE ADH, making the collecting duct LESS permeable
release LESS ADH, making the collecting duct MORE permeable
What are processes take place in the nephrons of the Kidneys
Distillation and Evaporation
Egestion and Excretion
Ultra-filtration and Re-absorption and Secretion
Mitosis and Meiosis
When you drink a larger volume of water than is required by your body tissues:
ADH secretion will be increased
ADH secretion will be inhibited
ADH secretion will not be affected
None of the above
When ADH is secreted, urine will:
Be more dilute
Be more concentrated
Have a larger volume
All of the above
Anti-diuretic hormone (ADH) affects the permeability of which section of the nephron tubules
Proximal (first) convoluted/coiled tubual
Loop of Henle
Bowman's capsule
Collecting duct
Kidney stone can be prevented by
Drinking less water
Eating dry fruits
Eating more seafood
Eating calcium rich food
