A 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.
Which of the following protects the body against infectious disease and foreign invaders?
[A] Leukocytes
[B] Red blood cells
[C] Endoplasmic reticulum (ER)
[D] Golgi apparatus
When certain types of white blood cells encounter bacteria, they are able to engulf them and bring them into the cell. What is this process called?

- Why is it advantageous for the cell membrane to be fluid in nature?arrow_forwardA man feels a shooting pain in his arm, then a thundering in his chest. Realizing that he is in the throes of a heart attack, he reaches for his self-injector of tPA (tissue plasminogen activator) and quickly injects himself. The tPA begins to break apart the blood clots that are blocking his heart’s circulation. This lifesaving protein is naturally found in the human body in tiny amounts. The man’s tPA drug, although identical to his own, was manufactured in bacteria. a. How is it possible for bacteria to express protein that was coded for by a human gene? b. Due to certain advances in biotechnology, it became much cheaper to produce tPA. What DNA technology made it possible to produce large quantities of this protein in bacterial cells?arrow_forwardReports in the media about stem cells usually state that they “turn into any kind of cell in the body.” Explain why this statement is only partially correct, including a description of how a stem cell maintains the population of stem cells.arrow_forward

Two weeks prior to a competition, a blood sample is taken and centrifuged, and the red blood cell component is stored. A few days before the event, the red blood cells are injected into the athlete. Why would athletes remove red blood cells only to return them to their bodies later? What problems could be created.arrow_forwardColchicine is used to treat gout. It alters cytoskeleton function.
