Solutes

Definition

Solutes are substances that are dissolved in a solvent to form a solution. In the human body, solutes include electrolytes, nutrients, and waste products that are essential for maintaining homeostasis.

5 Must Know Facts For Your Next Test

1. Solutes play a critical role in maintaining the body's osmotic balance.
2. Common solutes in the human body include sodium, potassium, glucose, and urea.
3. The concentration of solutes affects fluid movement across cell membranes through osmosis.
4. Electrolytes like sodium and potassium are crucial for nerve impulse transmission and muscle function.
5. Imbalance in solute levels can lead to conditions such as dehydration or edema.
