• Questions from you???

In humans, glucose is kept in balance in the bloodstream by insulin. Which concept does this best illustrate?
A. Adaptation
B. Metabolism
C. Homeostasis
D. Organization

A human kidney filters about 200 liters of blood each day.
Approximately two liters of liquid and nutrient waste are excreted as urine. The remaining fluid and dissolved substances are reabsorbed and continue to circulate throughout the body.
Antidiuretic hormone (ADH) is secreted in response to reduced plasma volume. ADH targets the collecting ducts of the kidney, stimulating the insertion of aquaporins into their plasma membranes and an increased absorption of water.
If ADH secretion is inhibited, which of the following would initially result?
A. The number of aquaporins would increase in response to the inhibition of ADH.
B. The person would decrease oral water intake to compensate for the inhibition of ADH.
C. Blood filtration would increase to compensate for the lack of aquaporins.
D. The person would produce greater amounts of dilute urine.

Finally, take attendance…
See you tomorrow!!!
