Verified step by step guidance

Identify the primary functions of the respiratory system: gas exchange, regulation of blood pH, and assisting in vocalization.

Understand that gas exchange involves the transfer of oxygen and carbon dioxide between the air in the lungs and the blood.

Recognize that the respiratory system helps regulate blood pH by controlling the levels of carbon dioxide, which can affect the acidity of the blood.

Acknowledge that the respiratory system assists in vocalization by providing airflow through the vocal cords, enabling speech.

Evaluate the statement about digestion: The respiratory system is not involved in the digestion of nutrients, which is primarily the function of the digestive system.
