Question

6 A 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.

Answer 1

Every organ is made up of two or more tissues,that working together to perform a specific activity..There are five basic tissue types..Epithelial tissues,connective tissues,adipose tissues,muscle tissues and nervous tissues.
Epithelial tissues:
It consists of cells that cover surfaces outside the body..it is tightly packed cells that act as a barrier to the movement of fluids and potential harmful microbes..This made as a specialized junctions that hold them tightly to reduce leaks..
connective tissues:
It consists of extracellular matrix..This matrix made up of protein fibers like collagen and fibrin in a solid,liquid or jellylike substance..It connects other tissues..some loose connective tissues found throughout the body,it supports organs and blood vessels..it connects bones with each other and muscles to bones..
Adipose tissues:
This is the body fat-bone,cartilage and blood in extracellular matrix liquid called plasma..
Muscle tissues:
It is important to keep the body upright,moving, and pumping blood and pushing food to the digestive tract..this muscle fibers have protein actin and myosin..
Nervous tissues:
This tissue involve in sensing stimuli-external or internal uses and processing and transmitting information..It has two main type of cells called nerve cells or neurons and glia..neurons generates electrical impulse and convey information very rapidly..Glia supports the neuronal function..
