Tissue Types
Epithelial, Connective, Muscular, and Nervous
Epithelial
This covers the inside and outside of body surfaces. It aids in protection, absorption, filtration, secretion, and sensory perception. The form of this tissue is important as it covers our entire body, thus protecting our entire from harmful forces. In the picture, it shows the different forms of this tissue. Not all epithelial tissue look alike, it can be elongated, flat, or square. This is important because our entire body does not require only one form of tissue. Each form has a different function for its particular body region.
Connective
This is the most abundant tissue. It connects, binds, and supports structures. Protects and cushions organs and tissues. It is made of very strong fibers so it can join together our bodily structures. That is how the form is important because without it, we would have now way of binding our body structures. In the picture, it shows that there is connective tissue surrounding the bone and joints of an arm.
Muscular
These tissues are responsible for body movement and moving blood, food, and waste throughout the body. In the picture, it shows all of the components of muscle and it shows the blood vessels. There are three different types of muscle tissue, skeletal, cardiac, and smooth. Cardiac muscle aids in pumping blood from our heart throughout the body. Skeletal muscle stabilizes joints and generates heat. Smooth muscle allows the stomach to contract and expel waste or for the uterus to expand during child birth. The form of muscle tissue is important because it composed of elongated cells that are bound together to help us with movement. Blood vessels are important because they allow for circulation.
Nervous
I personally believe that nervous tissue is most valuable to our bodies. Nervous tissue is located in the brain, spinal cord, and nerves. It generates and transmits nerve impulses to and from body organs via neurons. The form of this is important because it has tiny branches stemming off of it. This type of tissue is best suited for it's region of the body because it has a lot of branches to send impulses all over the body. It would be a very complicated process if it had to send all of this information through just one tube. But since it has many extending off of it, the process is made simpler.
