Concept explainers
To explain: The types of osmoregulatory challenges that humans do experience.
Introduction: The osmoregulation is a process by which an organism maintains balance of water in the body. It regulates the movement of the water and ions inside the cell. The fluid moves from the region of the higher concentration to the region of the lower concentration down the concentration gradient. The numerous examples include marine fishes, freshwater fishes and humans.
To determine: The mechanisms that humans have to meet the osmoregulatory challenges.

- Which of the following statements about osmoregulation is true? a. In freshwater invertebrates, salts move out of the body into the water because the animal is hypoosmotic to the water. b. A marine teleost has to fight gaining water because it is isoosmotic to the sea. c. Most land animals are osmoconformers. d. Vertebrates are usually osmoregulators. e. Terrestrial animals can regulate their osmolarity withoutexpending energy.arrow_forwardTest Your Understanding 3 To compensate for fluid loss, many marine bony fishes (a) accumulate urea (b) have glands that excrete glucose (c) eat a low-protein diet (d) excrete a large volume of hypertonic urine (e) drink sea waterarrow_forwardok I know hypothalamus is going to sense the high osmolarity of the blood, JGA sense low blood pressure with activate RAAs and release renin which going to convert into angiotensin and what? that’s where i got stuck…arrow_forward
