Key Terms

Electrolyte
A substance that produces an electrically conducting solution when dissolved.

Example: Sodium chloride (table salt) is a common electrolyte.

Ion
An atom or molecule with a net electric charge due to the loss or gain of one or more electrons.

Example: Sodium (Na+) is a positively charged ion.

Hydration
The process of providing adequate water to the body.

Example: Drinking water helps maintain hydration levels.

Homeostasis
The ability of the body to maintain stable internal conditions.

Example: Electrolyte balance is crucial for homeostasis.

Dehydration
A condition resulting from excessive loss of body water.

Example: Dehydration can lead to electrolyte imbalances.

Muscle Contraction
The process by which muscle fibers shorten and generate force.

Example: Calcium ions play a key role in muscle contraction.
