Chapter 1, Problem 2ILQ
Water concentration in the body is critical for proper functioning. A person’s body retains very tight control on water levels without conscious control by the person. Watch this video (http://openstaxcollege.org/l/H2Ocon) to learn more about water concentration in the body. Which organ has primary control over the amount of water in the body?

Appropriate water balance in our body is important to support vital functions. As a nutritionist or dietitian who works with the community health clinics and hospitals, discuss in detail how water balance can be achieved if you were assigned to give a talk on the importance of fluids in human body.

- In biology class one day, Mrs. Chabon wrote six physiological functions on the board. Then, she asked groups of students to each choose the three functions that are purposes of the excretory system. These are the lists they made. Group 1: maintaining pH level of blood; transporting hormones throughout the body; regulating growth Group 2: removing wastes from the body; digesting solid foods; maintaining salt and water balance Group 3: maintaining salt and water balance; maintaining pH level of blood; regulating growth Group 4: removing wastes from the body; maintaining pH level of blood; maintaining salt and water balance Which group correctly listed the functions of the excretory system? group 1 group 2 group 3 group 4arrow_forwardThe largest fluid component in the body is the: intracellular fluid extracellular fluid blood plasma cerebrospinal fluidarrow_forwardAn athlete is sweating profusely but does not rehydrate.

- Which action is the function of antidiuretic hormone (ADH)? Reduces blood volume Decreases water loss in urine Increases urine output Initiates the thirst mechanismarrow_forwardOn a particularly busy day, a student taking Anatomy and Physiology does not have anything to drink from 9:30 am until 6:30 pm. Osmoreceptors in the brain detect the decreased level of water in the blood. These receptors send a signal to the hypothalamus/posterior pituitary, which stimulates the release of antidiuretic hormone (ADH). This hormone acts on the nephron tubules and collecting ducts in the kidney to increase reabsorption of water, which returns that water to the blood. This retention of water has the additional effect of decreasing urinary output. As the fluid levels in the blood stabilize, the release of ADH ends.1. Whatisthevariablemonitoredbythisloop?2.
