Question
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.

- If a doctor injected a patient with what was labeled as an isotonic saline solution, but then the patient died, and an autopsy revealed that several of the patient's red blood cells had burst, such as in the image on the right, would it be true that the injected solution was really isotonic? Why or why not?arrow_forwardWhich of the following statements about cell division and cells is true? a) Adults have much larger cells than children, and adults have many more cells than children. b) Adults and children have cells that are about the same size, and both children and adults have about the same number of cells. c) Adults and children have cells that are about the same size, but adults have many more cells than children. d) Adults have much larger cells than children, but both children and adults have about the same number of cells.arrow_forwardCan a human red blood cells undergo a regulated cell division?

- Shock (failure of the circulatory system) is an abnormal condition in which blood flow is inadequate. The most common causes of shock are massive blood loss and obstruction of blood flow. As a result of shock, there is a failure to provide cells with oxygen and nutrients. In this circumstance, cells swell and lysosomal membranes rupture, among other effects. Describe how energy is generated during shock and why cell structure becomes destabilized.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_forwardIn humans, what kinds of cells undergo cell division most often? What kinds of cells almost never undergo cell division?arrow_forward
