• Endocrine system

• Nervous system

• All of the above

When ADH is secreted, urine will:

• Be more dilute

• Be more concentrated

• Have a larger volume

• All of the above

Identify Letter J

• Distal Convoluted Tubule
• Collecting Duct
• Peritubular Capillaries
• Proximal Convoluted Tubule

Anti-diuretic hormone (ADH) is released by which gland of the endocrine system

• Thyroid

• Pituitary

• Ovaries

• Adrenal

Anti-diuretic hormone (ADH) affects the permeability of which section of the nephron tubules

• Proximal (first) convoluted/coiled tubual

• Loop of Henle

• Distal (second) convoluted/coiled tubual

• Collecting duct

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 is osmoregulation?

• Control of water and salt in the body

• Control of blood pressure in the body
