Which hormone is responsible for water reabsorption in the collecting duct?

• Aldosterone

• Vasopressin (ADH)

• ANP (Atrial Natriuretic Peptide)

• Renin

1. The regulation of fluid and electrolyte balance is monitored primarily through changes in intracellular fluid (ICF)

• True

• False

1. What is the main force that drives fluid out of the capillaries at the arterial end?

• Osmotic pressure

• Hydrostatic pressure

• Oncotic pressure

• Filtration pressure

Increased capillary permeability can lead to edema by allowing plasma proteins to leak into the interstitial fluid

• True

• False

In conditions like bleeding, which type of thirst is triggered

• Osmotic thirst

• Cellular thirst

• Hyperosmotic thirst

• Hypovolemic thirst

The Renin-Angiotensin-Aldosterone (RAA) system promotes the excretion of sodium to decrease blood pressure

• True

• False

Which ion is primarily responsible for the osmotic activity in the extracellular fluid (ECF)?

• Potassium

• Calcium

• Sodium

• Chloride

Salt follows water, meaning that where water goes, sodium is likely to follow in physiological processes

• True

• False
