Key Concepts

Respiratory System

The respiratory system is responsible for taking air in and allowing gas exchange to occur in the lungs. When you breathe, air containing oxygen enters the lungs, and in the tiny alveoli, oxygen diffuses into the bloodstream while carbon dioxide is removed from the blood.

Circulatory System

The circulatory system, which includes the heart and blood vessels, transports oxygen-rich blood from the lungs to the muscles and other tissues. The heart pumps this oxygenated blood throughout the body, ensuring that muscles and organs receive the oxygen they need.

Oxygen Transport

Oxygen is carried in the blood by red blood cells, and specifically by the protein hemoglobin. Hemoglobin binds oxygen in the lungs and releases it in the tissues, which is essential for maintaining the oxygen supply required for cellular activities.

Cellular Respiration

Cellular respiration is the process by which cells use oxygen to help convert nutrients into energy. In muscle cells, this process occurs in the mitochondria, where oxygen is used to produce ATP, the energy that powers muscle contractions and other cellular functions.
