12 ATAR Human Biology - Osmoregulation

In the osmoregulation negative feedback model, an increase in osmotic pressure is the

• stimulus

• receptor

• modulator

• effector

• response

In the osmoregulation negative feedback model, osmoreceptors in the hypothalamus is the

• stimulus

• receptor

• modulator

• effector

• response

In the osmoregulation negative feedback model, hypothalamus water regulation centres is the

• stimulus

• receptor

• modulator

• effector

• response

In the osmoregulation negative feedback model, DCT and CD of the kidney nephron are the

• stimulus

• receptor

• modulator

• effector

• response

In the osmoregulation negative feedback model, ADH increases the permeability of the walls of the DCT and CD to water, more water is reabsorbed back into the bloodstream from the nephron leading to a smaller volume of more concentrated urine is the

• stimulus

• receptor

• modulator

• effector

• response

In thirst reflex osmoregulation feedback model, low water content in plasma leading to decreased saliva production and a dry mouth is the

• stimulus

• receptor

• modulator

• effector

• response

In thirst reflex osmoregulation feedback model, the thirst centre in the hypothalamus is the producing the sensation of thirst is the

• stimulus

• receptor

• modulator

• effector

• response

In thirst reflex osmoregulation feedback model, desire to drink activating drinking behaviour is the

• stimulus

• receptor

• modulator

• effector

• response

In thirst reflex osmoregulation feedback model, drinking water and water being absorbed by the alimentary canal is the

• stimulus

• receptor

• modulator

• effector

• response

In thirst reflex osmoregulation feedback model, water concentration increases in plasma increasing salivary output is the

• stimulus

• receptor

• modulator

• effector

• response
