Flashcards
Fluid Compartments
Fluid Compartments
The body's water is distributed into different compartments: intracellular fluid (inside cells), interstitial fluid (between cells), and blood plasma (in blood vessels).
Hypertension & Hormone Secretion
Hypertension & Hormone Secretion
High blood pressure (hypertension) triggers the body to increase the secretion of hormones that help regulate blood pressure, such as antidiuretic hormone (ADH) and aldosterone.
ADH and Water Reabsorption
ADH and Water Reabsorption
Antidiuretic hormone (ADH) increases the reabsorption of water in the collecting ducts of the kidneys, without significantly affecting sodium reabsorption.

Study Notes
I - Choose the correct answer
- Question 1: The greatest percentage of body water is in the extracellular fluid.
- Question 2: Hypertension increases the secretion of atrial natriuretic peptide.
- Question 3: Antidiuretic hormone increases water reabsorption without sodium reabsorption.
- Question 4: ADH hyposecretion can result in hypotonic hydration.
- Question 5: Reabsorption occurs in all structures of the nephron. The capillary hydrostatic pressure during filtration is greater than the osmotic pressure of the blood. Urine is 96% water.
- Question 6: Urine leaves the bladder through the urethra.
- Question 7: Urine formation involves filtration under the force of four pressures. Normal urine does not contain glucose. Normal filtrate contains few proteins.
II - True or False
- 1. Reabsorption of water in the descending loop of Henle is by passive transport (not active transport).
- 2. ADH activates reabsorption of water in the collecting duct (True).
- 3. The urethra collects urine from the kidneys and empties into the bladder (False, Ureters carry urine from the kidneys to the bladder)
- 4. Plasma protein levels in the glomerulus and Bowman's capsule are unequal after filtration.
- 5. Aldosterone promotes sodium and water retention, which increases blood pressure. (True)
III - Complete the Sentences
- 1. Metabolic water is water produced from chemical reactions.
- 2. The skin loses water through sweating and transpiration.
- 3. Edema is any abnormal fluid accumulation in a part of the body.
