Tissue Types

Module Two Lesson One Assignment by: Brielle Winner

Epithelial Tissue

Big image
The functions are protection, absorption, filtration and excretion, secretion, and sensory perception from stimuli. Squamous cells are flat and scale like, cuboidal are cube shaped, and columnar are tall and elongated. Simple is a single cell layer and stratified are stacked layers of cells. The form helps to do its job because it is found throughout the body to form a protective barrier.

Muscle Tissue

Connective Tissue

The functions are to connect, bind and support structures, protect and cushion organs and tissues, extracellular matrix can bear weight, stretch, and take abuse. As adipose it insulates and fills space as well as fat. Blood transports nutrients and bone supports the framework of our body and protects organs. Connective tissue comes as bone, cartilage, dense and loose, and blood. Form helps to do its job because it allows things to connect and transfer over what needs to be.

Nervous Tissue

The functions are to generate and transmit nerve impulses to and from the body organs via neurons. Some cells support, insulate, and protect neurons. It looks like a neuron with an axon, cell body, dendrites, and a myelin sheath. Form helps to do its job because it has an axon that it can send messages through very quickly and is covered by a protective sheath. It allows nerve signals to be sent throughout the body.

Defense of One Tissue Type

Muscle tissue is best for its location and function because it allows for movement, moving waste, blood, and food through the body's organs, and synchronous contractions of the heart. You need to have smooth muscle inside blood vessels and walls of hollow organs so that it can cause movement and make sure nothing ruptures. For example you cant have nervous tissue inside the heart because you don't want electrical impulses to be sent in and out of there. You also don't want connective because your not trying to connect, bind, or form a framework for the organs. Muscle tissue needs to be located where skeletal bones, blood vessels, or the heart is. You don't want to have exposed muscle tissue on the outside of your skin like epithelial tissue is.
