1. Epithelial tissue: This type of tissue covers the body's surfaces, lines cavities and organs, and forms glands. It serves as a protective barrier and helps with absorption, secretion, and sensation.
2. Connective tissue: Connective tissue provides support and structure to the body. It includes various types such as bone, cartilage, adipose (fat), blood, and lymph. Connective tissue also plays a role in immunity and wound healing.
3. Muscle tissue: Muscle tissue is responsible for movement and contraction. There are three types of muscle tissue: skeletal muscle (voluntary movement), smooth muscle (involuntary movement of internal organs), and cardiac muscle (involuntary contraction of the heart).
4. Nervous tissue: Nervous tissue consists of neurons and supporting cells called neuroglia. It is responsible for transmitting electrical signals throughout the body, allowing for communication and coordination of bodily functions.
5. Blood: Blood is a specialized connective tissue that consists of plasma, red blood cells, white blood cells, and platelets. It plays a crucial role in transporting oxygen, nutrients, hormones, and waste products throughout the body, as well as in immune response and clotting.

I. Epithelial Tissue - Covers body surfaces and lines cavities - Types: - Simple: single layer of cells - Stratified: multiple layers of cells - Glandular: secretes substances
II. Connective Tissue - Supports, connects, and protects other tissues - Types: - Loose connective tissue: few cells in a gel-like matrix - Dense connective tissue: tightly packed cells in a matrix - Cartilage: flexible, shock-absorbing tissue - Bone: hard, calcified tissue - Blood: fluid tissue consisting of red blood cells, white blood cells, and platelets
III. Muscle Tissue - Contracts to produce movement - Types: - Skeletal muscle: voluntary, attached to bones - Smooth muscle: involuntary, lines hollow organs - Cardiac muscle: involuntary, found only in the heart
IV. Nervous Tissue - Transmits information throughout the body - Types: - Neurons: specialized cells that transmit signals - Glial cells: support and protect neurons
