Step by step
Solved in 2 steps
- 1. There is a medical condition called Syndrome of Inappropriate Anti-Diuretic Hormone (SIADH) secretion, which can occur as a result of head trauma. Patients with this condition retain water and present with a volume imbalance. A) Name the type of volume imbalance and accompanying direction of changes in ICF and ECF volumes and osmolality. B) Calculate the changes in osmolality and volumes of extracellular and intracellular fluid compartments if 3 liters of water are retained by a patient with SIADH. You can assume that the patient’s initial volumes were ECF=14 L, ICF=28 L. And his initial body osmolality = 290 mOsM. Remember that the total solute in the ICF compartment is kept in place by the cell membrane barrier.87. A patient develops increased thirst and urinary frequency shortly after head trauma. If ADH (vasopressin) deficiency is the cause, which of the following changes in osmolality is expected? Osmolality Plasma ↑ ↓ O O O O Urine A) ↑ B) ↑ ↓ ↓How does ADH affect the amount of water in the body,and how does it accomplish this? How does this affect the osmolarity of the blood?
- 5. During an in vitro experiment studying aldosterone secretion, an isolated adrenal gland is perfused with various concentrations of potassium and angiotensin II Which of the following combinations of potassium and angiotensin II will cause the greatest increase in aldosterone secretion? Angiotensin II Potassium Increased Increased Increased Normal Normal Normal Decreased Decreased OA) OB) OC) D) DE) QF) G) H) ) Decreased increased unchanged decreased increased unchanged decreased increased unchanged decreasedDoes the fluid imbalance change the osmolarity (concentration) of body fluid?What causes isotonic imbalance?
- What is the osmolarity of the solution, and how does it compare with the osmolarity of blood plasma?a) What happens to plasma osmolarity when there is excessive water loss through sweating and it is not replaced? b) Describe the actions of natriuretic peptides, how is it activated and where are releasedAntidiuretic hormone (ADH) is produced in the pituitary gland and regulates the body's fluid volume and osmolality by affecting the number of active aquaporins (water channels) in the proximal tubules and the collecting duct. But what is it, above all, that drives the filtrate out of the tubules? a) Osmotic pressure formed depending on the composition of the filtrate b) Osmotic gradient in the medullary (kidney marrow) c) Hydrostatic pressure from the filtrate in tubules d) Blood pressure in the capillary
