Cell Organization

Multicellular Organisms Organisms made up of many cells. These cells work together so the organism can feed, digest, excrete wastes, and reproduce.

Cell Specialization Multicellular organisms benefit from cell specialization. Cells that specialize in certain functions come in a variety of shape and sizes, each designed to carry out a special function.

Cell Organization The cell is the smallest functional unit in the body. In order for our bodies to carry out larger more specific functions groups of cells work together. It is organized as follows: Cells  Tissues  Organs  Organ Systems

Tissues Tissues are a group of cells that are similar in shape and function. There are 4 major kinds of cells: –Epithelial cells –Nerve cells –Connective Cells –Muscle Cells Each cell is responsible for a specific function

Organs Tissues are organized into larger structures called organs. Many organs are composed of many different types of tissues. Each organ has at east one function.

Organ Systems Organ systems are groups of organs that have related functions. For example: The Circulatory system includes the heart; arteries, capillaries, and veins that all carry blood and waste from the heart to the tissues and back. Nerve tissue, epithelial tissue, connective tissue, muscle tissue and blood cells are all found in the circulatory system.

Major Organ Systems There are 8 major organ systems in the body: –Circulatory System –Nervous System –Respiratory System –Digestive System –Muscle System –Skeletal System –Excretory System –Endocrine System
