WorksheetsUnit 2 Topic 5: Osmoregulation
Total questions: 20
Worksheet time: 2hrs 40mins
ADH
Inhibits the absorption of water in the proximal convoluted tubule
Inhibits the absorption of water in the distal convoluted tubule
Increases the absorption of water in the proximal convoluted tubule
Increases the absorption of water in the distal convoluted tubule
ADH is created in the:
Hypothalamus
Posterior Pituitary Gland
Brain
Kidney
ADH is released from the pituitary gland into the:
Circulatory system
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
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 an organism has sweated a great deal and has not drank much water, this will be detected as:
Low blood pressure
Low blood volume
High blood concentration
All of the above
Changes in blood volume and concentration are detected in the brain cells in the:
Posterior Pituitary Gland
Anterior Pituitary Gland
Thalamus
Hypothalamus
Identify Letter I
Renal Pyramid
Renal Capsule
Renal Coretx
Renal Medulla
Osmoregulation is the homeostatic mechanism of controlling...
Blood glucose levels
Temperature
Oxygen levels
Water and mineral ion levels
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
Which area of the brain contains the receptors responsible for detecting changes in water potential
Hypothalamus
Medulla Oblongata
Amygdala
Hippocampus
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
If you are over-hydrated (high water potential in the blood), the body must excrete excess 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 two processes take place in the nephrons of the Kidneys
Distillation and Evaporation
Egestion and Excretion
Ultra-filtration and Selective Re-absorption
Mitosis and Meiosis
