Question
Chapter 4.3, Problem 1CSC
Summary Introduction
To determine: The features of the self-cells and donor cells that cause immune suppression.
Introduction: Immune suppression is defined as the decrease in the efficiency of the immune system to fight against diseases that cause microorganisms and other pathological agents. This condition occurs due to organ transplant or by the use of some medications.

Phagocytes are white blood cells that engulf and digest pathogens as a part of the immune
response of the body.
Compared to other types of cells, phagocytes are likely to have a higher concentration of
which of the following?
A lysosomes
B mitochondria
с chloroplasts
D ribosomes
A fluorescent molecule of 2000 daltons is microinjected into a single cell of an epithelial layer. When
the layer is examined in a fluorescence microscope, the molecule remains confined to that cell.
However, when a fluorescent molecule of 800 daltons is injected into a single cell of an epithelial
layer, it quickly appears in the adjacent cells. Which of the following is responsible for the spread of
the smaller molecule?
1. A) Desmosomes (maculae adherentes)
2. B) Focal contacts
3. C) Gap junctions
4. D) Intermediate junctions
5. E) Tight junctions (zonulae occludentes)
Reports 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.

- Cell-cell recognition occurs because _____ is secreted from the cell and is attached to the external phospholipidsarrow_forwardan average skin (epidermal) cell has a diameter of 30 micrometers. The majority of the surface of the human body is covered by skin cells. The average surface area of an adult male is 1.9 m2 and an adult female is 1.6 m2. Use the information above to calculate the approximate number of skin cells needed to cover the surface of your body (you can assume that you are an average human). Use this formula to determine the area an average skin cell covers: Area = π (radius)2 Plug the radius (1/2 the diameter) of an average skin cell into the equation. area of an average skin cell ____________________ Next, convert your surface area (average male or female) from m2 into mm2 your surface area____________________ Then, divide your surface area by the average area of a skin cell. number of skin cells covering your body ____________________arrow_forwardThe Adaptive Immune Response Is a Specific Defense Against Infection Researchers have been having a difficult time developing a vaccine against a certain pathogenic virus as a result of the lack of a weakened strain. They turn to you because of your wide knowledge of recombinant DNA technology and the immune system.

- Fresh out of college, Maria has her first job teaching school. When she goes for a pre-employment chest X-ray required by the school district, the technician places a lead-lined apron over her abdomen but not over any other part of Marias body. The apron prevents electromagnetic radiation from penetrating into the protected body area. What cells is the lead shield designed to protect, and why?arrow_forwardFigure 5.12 A doctor injects a patient with what the doctor thinks is an isotonic saline solution. The patient dies, and an autopsy reveals that many red blood cells have been destroyed. Do you think the solution the doctor injected was really isotonic?arrow_forwardThe basic unit of life is the cell, and now in a modern laboratory even mammalian cells can be easily cultured in a test tube or a flask. In this unit you have learned about the biomolecules of life such as carbohydrates, lipids, proteins and nucleic acids which come together to allow cells to form and function. You are required to design a cell culture medium for maintaining mammalian cells, what are your key considerations? (hint: you need to describe the key nutrients and the underlying reason for them, and the pH of your medium).arrow_forward
