It is illegal in the United States to pay for a transplant organ, and doctors cannot perform a transplant operation unless the patient is at the top of the official list. However, some wealthy people in need of a kidney transplant go overseas to other countries where the laws are not enforced strictly. Suppose a wealthy person finds a poor person willing to sell his or her kidney and then purchases the kidney. What do you think of this? If the poor person is willing, is there any harm in it? Why does the United States prohibit the sale of organs when other countries look the other way?
Some people advocate drinking one’s own urine, claiming significant health benefits. What problems do you see with this “alternative therapy”? Are there conditions under which this might be advisable?
Compare and contrast the functions of the kidneys and the heart using a table. If both were candidates running for the presidential elections inside your body, which one would choose and why? If you do not want to vote for either the heart or the kidney, which organ would you vote for and why? Think of a way to make your reason more substantial by considering the role of both the heart and the kidneys in blood pressure regulation.

- A donor underwent physical examination and was assessed as healthy with no known illnesses. The donor’s kidney was subsequently transplanted to a recipient. Transplantation was successful. Not long after the transplantation, the recipient was diagnosed with kidney cancer. Can you make an educated speculation as to why the recipient, who had no history of kidney cancer or any other types of cancer, developed kidney after the transplantation?arrow_forwardBlood vessels travel in parallel to provide fresh blood to all tissue. However, one of the exceptions is the two capillary beds of the kidneys located in series. Blood flow occurs as follows: afferent arteriole- glomerulus- efferent arteriole - the peritubular capillaries. How does this series of blood flow benefit the kidneys and homeostasis?arrow_forwardThe presence of a full bladder triggers the bladder to contract. As a little urine is released, this causes more contractions, which will completely empty the bladder. This is an example of: a. homeostatic regulation b. uroregulation c. negative feedbackd. positive feedback e. reverse feedbackarrow_forward
- Assume you have a 1% salt solution in 3 different beakers. In beaker one, you place a dialysis bag with just water in it. In beaker two, you place a dialysis bag with a 1% salt solution in it. In beaker 3, you place a dialysis bag with 10% salt solution in it. Predict what will happen to each of the dialysis bags after 24 hours (get larger, get smaller or no change). Use the terms hypotonic, hypertonic and isotonic to explain your answer.Part 2: List the four types of tissue and compare and contrast 2 of these types of tissues.

- Many caffeinated beverages such as coffee, tea, and cola drinks have diuretic effects on the body. Why do caffeinated beverages increase the volume of urine? Select one: a. Caffeine increases ADH, which increases the reabsorption of water in the kidneys. b. Caffeine inhibits ADH, which reduces the reabsorption of water in the kidneys. c. Caffeine increases ADH, which reduces the reabsorption of water in the kidneys. d. Caffeine inhibits ADH, which increases the reabsorption of water in the kidneys.arrow_forwardAlthough the kidneys are probably best known as filtration organs, they also help control blood pressure.

- 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 principle of dialysis is employed in artificial kidneys.
