1591 - What is the structure and function of animal tissue?
The structure of animal tissue is made up of groups of similar cells that work together to do a specific job. There are four main types of animal tissue:
Epithelial tissue: This tissue covers and protects the body's surface, like skin and the lining of organs. It also helps absorb things, like food and water.
Connective tissue: This tissue connects different parts of the body and gives it support. It's like a strong glue that holds everything together, like bones, blood, and tendons.
Muscle tissue: This tissue helps the body move by contracting and relaxing. There are three types of muscle tissue: skeletal (attached to bones), smooth (in organs), and cardiac (in the heart).
Nervous tissue: This tissue helps the body send and receive messages. It's like a communication system that includes the brain, spinal cord, and nerves.
These tissues work together to keep the body healthy and functioning properly.
