Water never enters or leaves our . “Cells, Tissues, Organs & Systems”. Levels of Organization. Tissues. Groups of similar cells. Found in all multicellular organisms. Ex. Muscle tissue, nerve tissue, epithelial tissue, etc.. Organs. Cells. In the late 1600’s British born Robert Hooke coined. the term "cell" to describe the basic unit of life.. Where did the term cell come from?. In 1665 Robert Hooke inspected thin slices of cork and found that they consisted of millions of small, “irregular units”. 4 basic types of tissues in human body contribute to homeostasis by providing diverse functions including. protection. support. communication among cells. resistance to disease . & many more. Tissues & Homeostasis. 1 Animal Body Plans 2 Components of Organisms What are the levels of body organization from simple to most complex? 3 Components of Organisms Cells---- Single cells with specific functions Tissues---- organs. Literally, histology means tissue or web. To study tissues, certain techniques an instruments are used to study tissues. Tissue Preparation.

Lecture 5. Tissues. . The tissue is a group of cells which are similar in the shape (form), structure and function. . Tissues exist not as isolated units but rather in association with one another in variable proportions, forming different organs and systems of the body. . 1. I. .

Supports the cells and the fluids that transports nutrients to the cells .. Tissues – Introduction. a group of similar cells specialized to carry on a particular function. tissue = cells + extracellular matrix. nonliving portion of a tissue that supports cells. 4 types. epithelial = protection, secretion, absorption.
