There are four main types of tissues in the human body:
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 and secretion.
2. Connective tissue: Connective tissue provides support and structure to the body. It includes bone, cartilage, adipose (fat) tissue, blood, and lymph. Connective tissue also helps with the transportation of nutrients and waste products.
3. Muscle tissue: Muscle tissue is responsible for movement in the body. There are three types of muscle tissue: skeletal muscle (voluntary movement), smooth muscle (involuntary movement of internal organs), and cardiac muscle (involuntary movement of the heart).
4. Nervous tissue: Nervous tissue is found in the brain, spinal cord, and nerves. It is responsible for transmitting electrical signals throughout the body, allowing for communication and coordination of bodily functions.
