Epithelial tissue covers the body surface and forms the lining for most internal cavities. The major function of epithelial tissue includes protection, secretion, absorption, and filtration.
<u>Explanation:</u>
Epithelial tissue spreads throughout the body surface covering line body cavities and hollow organs which form the major tissue in the glands. Epithelial tissue covers the outside of the body and lines organs, vessels, and cavities.
Endothelium joins with the inner tissue lining which covers the brain, lungs, skin, and the heart. It acts as a barrier protecting the body and the environment and maintains the process of protection, filtration, absorption, excretion, and sensation.
Covering and lining epithelium and the Glandular epithelium which helps in surrounding the glands within the body surface are the characteristics feature in the human body.
When the resource base is unlimited the population is said to take an exponential growth. This will results in a J shaped curve when the growth of resources is limited the population grows is decreased.
Population numbers will increase and the maximum growth of the man will be attained which is known as the biotic potential.
This type of growth rate can be seen in the population where the areas are newly colonized by man or in areas that are small. The growth can be calculated by the density-dependent factors.
These factors include the predator numbers, the availability of food and the resources and the spread of pathogenic diseases.
