Chapter 8, Problem 20TYK
Summary Introduction
To determine: The number of cell divisions in bone marrow per second to replace red blood cells.
Introduction:
Erythropoiesis is the process of formation and maturation of all blood cells. Erythrocytes or red blood cells are continuously produced in the bone marrow. These cells stay in blood circulation for about 120 days.

The average diameter of the amphibian red blood cell is 0.01 mm. How many red blood cells would be equal to the average diameter of a human red blood cell?
Why does this red blood cell have a nucleus?
Elsa’s blood sampled was analyzed under a microscope and it was determined that her red blood cells were “hypochromatic” and “microcytic.” Explain, in your own words, what these terms mean.
If you place a sample of your blood (which is primarily red blood cells) in a beaker of distilled water, what do you think would happen to the RBCs? Why? Is water moving into or out of the cells? Is the water hypotonic, isotonic, or hypertonic compared to the intracellular fluid in the RBCs? Knowing that normal cellular osmolarity is 300 mOsmol, what do you think would happen if you mixed your RBCs with a 1.8% NaCl solution? Why? What is the osmolarity of the 1.5% NaCl solution?
RBCs with distilled water and why
Is water moving into or out of the RBCs in this solution?
Is the water hypo-, iso- or hypertonic?
RBCs with 1.8% NaCl solution and why
Osmolarity (osmol/L) of the 1.8% NaCl

- Describe the reason why the red blood cells placed in one solution swell and burst and also why the red blood cells placed in another solution shrink and wrinkle.arrow_forwardTransport of biomolecules to tissues takes place through capillary walls by both convection and diffusion. Consider an endothelium in which the gaps between the cells are characterized by the following dimensions: L=1 µm long, h=200 nm high, and W=10 nm in width (the last dimension is the distance between the two cells). The fluid is at 37degC and has the same properties as physiologic saline. Let the average pressure in the capillary be 45 mm Hg and let the pressure in the tissue be 0 mm Hg (ignore osmotic effects). Consider a small solute that has a diffusion coefficient of 1x10-5 cm2/s. Does this solute pass across the endothelium by diffusion or is it primarily carried by flow?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
- Is red blood cells(erythrocytes) considered true cells histologically? Why or why not? Explainarrow_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_forwardRecently, athletes have begun to take advantage of the benefits of extra red blood cells, in a process known as `` blood doping`` (You can do your own research on it). 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_forward
- (AKS 1b1 / DOK 2) Patients with a genetic condition known as cystic fibrosis struggle with symptoms such as lung and digestive problems. The cells of patients with the disease do not transport water or other materials out of the cell efficiently. Therefore, patients' cells have a build up of water and other substances inside the cell. Which of the following BEST describes how cystic fibrosis impacts cells? O A. Cystic fibrosis affects the cell membrane increasing cellular transport and homeostasis B. Cystic fibrosis affects the lysosomes increasing cellular transport and homeostasis C. Cystic fibrosis affects the Golgi decreasing cellular transport and homeostasis D. Cystic fibrosis affects the cell membrane decreasing cellular transport and homeostasis E:17 AM P Type here to search IOI & 7 %23 3 $ 4 Rarrow_forwardLabel the nucleus, cytoplasm, and cell membrane of the following pictures. The red one is the human red blood cell under HPO, while the orange one is the toad red blood cell. Describe each cell and compare the two.arrow_forwardYou have been asked to do a strucutural study to understand how increasing cell surface area affects cell size, cell shape and functions. What cell type would help you most efficiently observe the effects of increasing surface area? Choices: A. Monocytes from the blood serum. Monocytes are largely roughly spherical cells. B. Red Blood cells from the bone marrow. The shape of Red blood cells is a biconcave disk and looks like a donut. C. Stem cells from skin. In this case assume a skin stem cell is flat and plate like. D. Microvilli covered cells from the intestines. Microvilli are tiny hair like protrusions in the plasma membrane of intestinal cells that increase the absorption of nutrients in the intestines.arrow_forward
- Explain why the term “formed elements” is used instead of “blood cells.”arrow_forwardYou are a doctor in the emergency room. You have a patient whose blood cells are composed of the following: 80 molecules of glucose, 50 molecules of hemoglobin, 20 molecules of dextrose, and 2000 molecules of water. a. What is the total solute concentration of her cells? b. If you needed to make an isotonic solution of saline for her IV, how many salt molecules would you need to add to 1000 molecules of water? How do you know this is the correctamount?arrow_forwardA 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_forward
