Tissues of Human Body
Assignment
Summarize4 how you understand about TISSUES of the body.
I.
Tissue is a group of organizational cells that shares the same embryonic origin in which it plays specific
function within the body. The branch of biology that studies the microscopic anatomy of tissue is called Histology. There
are four main type of tissue that were mentioned; epithelial tissue, connective tissue, muscle tissue, and nervous
tissue.
First, epithelial tissue is made up of epithelial cells that can be found in the linings of the organ. It has two types which are
called simple epithelial tissue that contains a characteristic of single layer and stratified epithelial tissue which contains
several layers. Epithelial tissue can also act like a gatekeeper, controlling what can pass through. Second is the
connective tissue, the most abundant tissue in the human body. The connective tissue binds all the cells and organs all
together so they can work cooperatively. And, it also acts as the transportation of essential substances. It has seven types
that were also mentioned; loose connective tissue, dense connective tissue, adipose tissue, reticular tissue, cartilage,
blood, and bone tissue. Third, muscle tissue is all about movement of your body and body organs. It contains fibers that
intertwine and bind together resulting to contraction and relaxation. The muscle tissue has three types; skeletal muscle
tissue, smooth muscle tissue, and cardiac muscle tissue. Lastly, the nervous tissue which forms the organs of nervous
system. It allows the generation and propagation of electrochemical signals in the form of nerve impulses (neurons) that
communicate between different regions of the body.
Enumerate different types of tissues of the body. Identify their functions Five examples and
define each.
1. Connective Tissue
- Is a type of tissue that connects all the body organs and cells to function all together.
II.
Function: it plays an essential role in protecting, supporting and binding various tissues and organs throughout the body.
-
2. Skeletal Muscle Tissue
Is commonly attach to the bones which is essential to help your body move.
Function: helps to support your posture, moves the substances forward in the organs and can also produce heat during
contraction to maintain your body with proper temperature.
-
3. Cardiac Muscle Tissue.
Also known as the myocardium which is made up of sarcomeres that allow for contractility. Unlike
skeletal muscle, it is under the involuntary control.
Function: pumps out the blood from the heart.
-
4. Epithelial Tissue
Is the protective layer of the cells that covers all the internal and external surfaces of the body, that is
why it is located in the lining of the organs.
Function: plays as the protective barrier, secretion and absorption of nutrients and other substances.
-
5. Cartilage
Is a type of connective tissue that has a dense of network collagen fibers, providing for support and
assisting movement.
Function: It plays an important role in covering and protecting the ends of bones at joints and other structural component.
III.
How tissues of the body undergo repair? Describe the major events in tissue repair.
Tissue regeneration or tissue repair is a process in which the new growth completely restores the function and structure in
the same state again as it was before. This will only happen when the cells within the tissue contains proliferative
capabilities and the framework underlying the tissues must not be damaged. Thus, the older cells will always be replaced
by the newer cells.
Furthermore, the major events in tissue repair consists of inflammation where blood leaking give way for blood vessels to
undergo coagulation (coagulation is a process by which blood changes into solid state to form a blood clot in order to
prevent excessive bleeding). The proliferative phase is the rapid increase of tissues. It can be divided into four phases; revascularization, granulation, re-epithelialization, contraction. While the final phase is the remodeling where the wound
matures and undergo refinement and strengthening newly formed tissue

IV.
Describe the process of inflammation in response to tissue damage, and explain why
inflammation protects the body.
The process of inflammation in response to tissue damage happens where it undergoes in a state to eliminate
the cause of cell injury and clear out damaged cells to start tissue repair. This way, it can protect the body by
preventing any spread of infection by isolating the area to fight off pathogens and destroy invaders such as
bacteria, viruses or other harmful agents that wants to attack the immune cells.
V.
Enumerate some effects of aging on tissues. How can prevent early tissue aging?
Some effects of aging can vary on:
1.
2.
3.
4.
5.
Decreased elasticity
Slower cell regeneration
Loss of muscle mass
Reduced bone density
Decreased of collagen production
The tissue aging can be prevented by allowing the body to practice balance diet and adopt a healthy lifestyle with
sufficient sleep and stress management.
