Front

What is the role of osmoreceptors in the body?

Back

They detect changes in osmotic pressure and help regulate fluid balance.

Front

Explain the difference between strong acids and weak acids.

Back

Strong acids ionize completely in solution, while weak acids ionize less completely.

Front

What physiological condition can result from excessive vomiting?

Back

Metabolic acidosis due to loss of bicarbonate.

Front

How does hyperventilation affect blood pH?

Back

It causes respiratory alkalosis by decreasing CO₂ levels.
