Types of Tissues
By: Tucker Key
Epithelial Tissue
Epithelial Tissue covers the inside and outside body surfaces, including organs, Lines the cavities, tubes, ducts and blood vessels, and main gland areas. As you can see in these images, the epithelial cells are held very tightly together in order to form a protective barrier. Epithelial Tissue is all over the body and does a great job covering the surface cavities.
Connective Tissue
As you can see in this picture, Connective tissue is all over! Connective tissue connects, binds, supports, protects organs and other tissues. This picture shows all of these functions that connective tissue can do in the elbow and makes up the majority of it too! The bottom image shows the microscopic cells that make up this tissue.
Muscular Tissue
This image shows the three different muscle types and what they are associated to. The muscle known as the biceps is a skeletal muscle and bundles and releases in a voluntary form. The smooth muscles that make up the walls of the stomach is involuntary and moves food throughout the body. Cardiac muscle lines the heart and involuntarily keeps it pumping.
Nervous Tissue
Nervous tissue generates and transmits nerve impulses to and from body organs via neurons. The nucleus of these cells generates messages and send it out of there stems to other locations in the body. The bottom image shows all of these tissue cells connecting and shows the idea of how they all transmit from one to the other.
Defense on Epithelial Tissues
Epithelial Tissue is best for its location because it literally covers the entire body in a layer of its tissue. Without this tissue in its location none our body would be safe from disease. and infection, or cut, or germs could easily become deadly. We need our skin of the Epithelial tissue to keep healthy and avoid sickness.
