Textbook Question
Chapter 3, Problem 5AWK
Recently, a young man from Derby in the United Kingdom entered a contest and drank 26 pints of water in a very short time. He later died of complications due to hypotonic hydration, also known as water intoxication. How were his body's cells affected by the excess water, and how might that have contributed to his death?

- A patient was involved a serious accident and lost a large quantity of blood. In an attempt to replenish body fluids, plain water is added to the blood directly via one of his veins. What will be the most probable result of this transfusion? a. The patient's red blood cells will shrivel up because the blood has become hypotonic compared to the cells. b. The patient's red blood cells will swell and possibly burst because the blood has become hypotonic compared to the cells. c. The patient's red blood cells will shrivel up because the blood has become hypertonic compared to the cells. d. The patient's red blood cells will burst because the blood has become hypertonic compared to the cells.arrow_forward1.Hemocytes are stem cells which become Red Blood Cells (RBC). The RBCs are filled with a protein called hemoglobin. Such a cell product is stored in cell structures that are: a) formed from the nucleus, b) formed from as vesicles from the endoplasmic reticulum, c) engulfed into the cell by pinocytosis, d) released into the blood by exocytosis e) ingested by phagocytosis. 2.The Prokaryotes are associated with the following structures EXCEPT: A) ribosomes, B) Lysosomes and liposomes, C) a nucleoid area, D) mesosomes, E) chlorophyll. 3.

What is this process called?arrow_forwardExposure to tobacco smoke immobilizes cilia, and they eventually disappear. How might this effect explain why smokers have an increased incidence of coughing and respiratory infections?arrow_forwardA patient has had a serious accident and lost a lot of blood. In an attempt to replenish body fluids, a large amount of distilled water was transferred directly into one of his veins. What will be the most probable result of this transfusion? It will have serious, perhaps fatal, consequences because the red blood cells will be hypertonic relative to the body fluids and the cells will burst. It will have serious, perhaps fatal, consequences because the red blood cells will be hypotonic relative to the body fluids and the cells will shrivel. It will have no unfavorable effect as long as the water is free of viruses and bacteria. It will have no serious effect because the kidneys would quickly eliminate the excess water. It will have serious, perhaps fatal, consequences because there will be too much fluid for the heart to pump.arrow_forward
- (For this question my professor says that answer choice b) or d)is not correct. The correct choice is answer c). I just need help for the explantion as to why it is choice c. ) Question:The phospholipid composition of cell membranes causes the membranes to be impermeable to water molecules. However, Ca2+ and Mg+ and Cl- ions diffuse in and out of the cell because: a) Water is soluble in fatty acids found in phospholipids b) the Fatty Acid portion of the phospholipid component interacts with water c) the fatty acids are hydrophilic d) protein molecules embedded in the membrane function as H20 channels through the membrane, e) water is nonpolar.arrow_forwardWe get iodine in our diet but over 99% of it ends up in our thyroid gland with very little in the rest of the body.
