Textbook Question
Chapter 40, Problem 11TYU
SCIENCE. TECHNOLOGY. AND SOCIETY Medical researchers are investigating artificial substitutes for various human tissues. Why might artificial blood or skin be useful? What characteristics would these substitutes need in order to function well in the body? Why do real tissues work better? Why not use the real tissues if they work better? What other artificial tissues might be useful? What problems do you anticipate in developing and applying them?

Multiple Tissues Make Organs
You are a part of a research group who wants to build and organ in the lab for organ transplant patients. If this worked the patients don't have to wait for
donors. The organ you are building requires the following functional abilities:
1. It has to be able to resist mechanical stresses such as friction and abrasion. This tissue will get sloughed off.
2. The ability to contract involuntarily (you don't have to think about it for it to contract) when stimulated by the nervous system.
3. There has to be a tissue that can stimulate the contraction of the other tissue involved.
4. The ability to resist stress, tension and force from many different directions.
5. There has to be a tissue that acts like glue holding all of the other tissues together to make the organ.
Part 1 - Questions you will answer.
1. What are the five tissues that will make up this organ? Justify your choices by describing the characteristics of each known tissue.
2. What organ in the human…

of tissue studied this week: epithelial tissue, muscles,
connective tissue (blood, bone, fat, cartilage,
ligaments...), and nervous tissue.

- Question 2: What is The Applications and Requirements for Tissue Engineering? Talk about it briefly.arrow_forwardA hypothetical organ has the following functional requirements : (1) the ability to resist surface abrasion and mechanical stresses;(2) the ability to contract involuntarily when stimulated by cells of the nervous system; and (3) the ability to resist tension in many different planes of force. The organ needs one tissue to carry out each of these requirements, and it also needs one tissue to " glue" all other tissues together, and one tissue to stimulate the contracting cells. What are the five tissues that will make up this hypothetical organ ? Justify your choices .arrow_forwardPlease please do homework in half an hour please O • Define decellularization.

- Tissues, Organs, & Systems Multi-cellular organisms have many cells that work together in specific ways, each group performing certain functions. When each group does its part, the organism gets everything that it needs. A Tissue is a large group of cells that all have the same purpose or function. Each kind of cell has unique characteristics such as shape, size, flexibility, color and texture. Nerve cell combined with other nerve cell to make nerve tissue. Muscle cell combined with other muscle cell to make muscle tissue. Bone cell combine with other bone cell to make bone tissue. An Organ is a group of tissues that work together to do a certain job for the body. Some of the human body’s organs include the stomach, lungs, heart, kidneys, brainand liver. Some of a plant’s organs include roots, stems, fruit and leaves. When several different organs join to meet the organism’s needs, they are working together in an organ system. There are several different organ systems constantly…arrow_forwardMatching. Match the tissue type to its anatomy or physiology.

Next, choose any organ in that system, and explain its specific function within the system. Next, choose any tissue type in that organ, and explain how it specifically helps the organ do its job. Next choose any cell type in that particular tissue, and explain how it contributes to the tissue’s function. Finally, choose any molecule (or atom) found in that specific cell and explain what the cell uses that molecule for.arrow_forward
