Making sure that your body maintains homeostasis is not an easy task. The task is difficult because your internal environment is always changing. Your body must do many different jobs to maintain homeostasis. Each cell in your body has a specific job in maintaining homeostasis. Your cells are organized into groups. A group of similar cells working together forms a tissue. Your body has four main kinds of tissue – epithelial tissue, connective tissue, muscle tissue, and nervous tissue. These tissues work together to form organs, which help maintain homeostasis.

Three major types of nutrients – carbohydrates, proteins and fats – make up most of the food you eat. Chemical substances called enzymes break these nutrients into smaller particles for the body to use.
