The Respiratory System - Estrella Mountain
Cellular respiration involves the breakdown of organic molecules to produce ATP. A sufficient supply of oxygen is required for the aerobic respiratory machinery of Kreb's Cycle and the Electron Transport System to efficiently convert stored organic energy into energy trapped in ATP.

The Human Respiratory System - Biology Pages
Air enters the nostrils passes through the nasopharynx, the oral pharynx through the glottis into the trachea into the right and left bronchi, which branches and rebranches into bronchioles, each of which terminates in a cluster of alveoli.

Penn Medicine - Respiratory System Information
All the body cells metabolically consume oxygen, and discharge carbon dioxide. To cover this need, respiration takes place internally (at the cellular level) and externally (ventilation/breathing). Ventilation involves the inhalation of atmospheric air into the lungs via the nose and mouth through branching passageways, and the exhalation of carbon dioxide.

Respiratory System Anatomy, Diagram and Function - Healthline
Every tissue within the body requires oxygen to function. The respiratory system, which includes air passages, pulmonary vessels, the lungs, and breathing muscles, provides oxygenated blood to the body tissues and removes waste gases.

Respiratory System - Wikipedia, the Free Encyclopedia
The respiratory system (called also respiratory apparatus, ventilatory system) is a biological system consisting of specific organs and structures used for the process of respiration in an organism. The respiratory system is involved in the intake and exchange of oxygen and carbon dioxide between an organism and the environment.
