Verified step by step guidance

Identify the main functions of the respiratory system. The primary functions include gas exchange, regulation of blood pH, voice production, olfaction, and protection against pathogens.

Understand that gas exchange is the process of exchanging oxygen and carbon dioxide between the body and the environment, which is crucial for cellular respiration.

Recognize that the regulation of blood glucose levels is primarily a function of the endocrine system, particularly involving hormones like insulin and glucagon.

Acknowledge that digestion of nutrients is a function of the digestive system, which involves breaking down food into absorbable units.

Note that the production of red blood cells is a function of the skeletal system, specifically the bone marrow, and is not directly related to the respiratory system.
