Health Is the Condition of an Organism

Health is the condition of an organism or one of its parts in which it performs its vital functions normally or properly: the state of being sound in body or mind.

Water is the most important and abundant inorganic compound in all living systems. Although humans might be able to survive for weeks without food, without water you would die in a matter of days. Nearly all the body's chemical reactions occur in a watery medium. Water has many properties that make it such as indispensable compound for life.

Nutrients are chemical substances in food that body cells use for growth, maintenance, and repair. The six main types of nutrients are water, carbohydrates, lipids, proteins, minerals and vitamins. Three organic nutrients--carbohydrates, lipids, and proteins provide the energy needed for metabolic reactions and serve as building blocks to make body structure. Some minerals and many vitamins are components of the enzyme systems that catalyze metabolic reactions. Essential nutrients are specific nutrients molecules that the body cannot make in sufficient quantity to meet its needs and thus must be obtained from the diet. Some amino acids, fatty acids, vitamins and minerals are essential nutrients.

Exercise is regular or repeated use of a faculty or bodily organ, bodily exertion for the sake of developing and maintaining physical fitness. Exercise is needed to stay healthy. And to live a full and active life.
