Explain the kidney's role in water conservation. How much water is reabsorbed (by following other reabsorbed substances) by osmosis? How much water does the nephron loop and collecting duct have to be "tricked" into reabsorbing? How exactly does that work? How do hormones control this process? What effect does alcohol have?

How does ADH alter urine production?  Please include it's mechanism of action.

Answer the question in the photo

Which of the following is NOT a function of the excretory system? *       Filtration of wastes from the blood.       Secretion of ADH from the collecting duct.       Maintaining pH balance by secretion of H+ ions.       Osmoregulation via sweating.       Releasing carbon dioxide waste from the lungs.

Morphine, taken for severe pain, causes a decrease in the amount of urine produced, regardless of levels of hydration. Which of the following rows identifies the effect of morphine on antidiuretic hormone (ADH) secretion and the reabsorption of water by the kidneys? Row Antidiuretic Hormone (ADH) Secretion Reabsorption of Water stimulates ADH secretion more water is reabsorbed inhibits ADH secretion less water is reabsorbed inhibits ADH secretion more water is reabsorbed stimulates ADH secretion less water is reabsorbed

how does aldosterone raise blood pressure? Choose all that apply: distal convoluted tubule, collecting duct, increase sodium reabsorption, decrease sodium reabsorption, passive movement of water.

What is the function of antidiuretic hormone? Group of answer choices 1. It increases the permeability of the collecting ducts to sodium so more is reabsorbed. 2. It decreases renin secretion. 3. It increases aldosterone secretion. 4. It causes a high volume of less concentrated urine to be produced. 5. It increases the permeability of the collecting ducts to water so more is reabsorbed.

+ 1. Summarize the role of the kidneys in each of the following functions: Adjusting blood volume (and so blood pressure) and the volume of interstitial fluid and lymph Regulating calcium ion levels Stimulating the production of red blood cells (erythropoiesis) Regulating blood pressure Regulating blood glucose levels Adjusting the pH of body fluids Regulating the blood Na* and K levels Regulating blood Cl levels Getting rid of wastes such as urea, ammonia, uric acid, creatinine, urobilin from breakdown of hemoglobin, foreign substances such as drugs and environmental toxins

You suspect a person is suffering from a central diabetes insipidus. When untreated and reasonably hydrated, their urine concentration should be . After injection of a synthetic ADH/vasopressin urine concentration should dilute; become concentrated concentrated; remain unchanged concentrated; become dilute dilute; remain unchanged
