Tissues

Tissues • Cells are arranged in Tissues that provide specific functions for the body. • Cells of different tissues are structured differently which leads to their differences in function.

The study of tissues is called histology • Arrangement of tissues embedded in or around nonliving material is called a matrix

• • • Tissues of the human body include 4 major types. 1. Epithelial 2. Connective 3. Muscle 4. Nervous

Epithelial Tissue • • • Covers and protects body surface Lines body cavities Specializes in moving substances into and out of blood Forms many glands Many different forms of this type of tissue

Connective Tissue • Specialized to support the body surface to connect and hold them together • Transport substances through the body • Protect it from foreign invaders • Usually found spread apart from other connective tissues with non living matrix between

Muscle Tissue • Produces movement • Muscle cells are specialized for contractility • Produce movement by shortening of contractile units found in cytoplasm • Have many nuclei • 3 main types: Cardiac, smooth, skeletal

Nervous Tissue • The most complex tissue in the body • Communication between various parts of body • Coordination of body functions

Memorizing vs. Learning • How could you remember the 4 types of tissues found in the body?
