Alveoli are tiny sacs within our lungs that allow oxygen and carbon dioxide to system comes into direct contact with the circulatory system, or blood vessels.

Acute lung injury and acute respiratory distress syndrome

It is the alveoli that receive the oxygen and pass it on to the blood. The alveoli are surrounded by tiny blood vessels, called capillaries. The alveoli and capillaries both have very thin walls, which allow the oxygen to pass from the alveoli to the blood. The capillaries then connect to larger blood vessels, called veins, which bring the oxygenated blood from the lungs to the heart.

The largest veins that do this work are called the pulmonary veins, and they connect directly to the heart. Breathing and Respiration Sometimes we use the terms breathing and respiration to mean the same thing, but they actually are distinct processes.

Breathing is the process of moving oxygen-rich air into and out of the lungs. Respiration refers to how the cells of the body use oxygen to create energy and how they exhale carbon dioxide that is a waste product of this process.

The lungs have to work continuously because the body cells are constantly using up oxygen and producing carbon dioxide. Unlike the heart, the lungs have no muscle tissue. Instead, muscles in the rib cage and the diaphragm do all the work of lifting the ribs upward and outward to let the air in, and then relaxing to force the air out.

Gas Exchange Physiology Animation - MADE EASY

Gas Exchange Why are oxygen and carbon dioxide such important gasses? All cells of the body need energy to do their work. They get energy by combining sugars or other food materials with oxygen. This chemical reaction is something like burning.

Inside the body cells the chemical reaction gives off heat and other forms of energy. This energy provides the power we need to talk and move and think.

Alveoli & Capillaries - The Respiratory System

When a fire burns, carbon dioxide is formed. When a body cell combines sugar with oxygen to get energy, carbon dioxide is formed there, too. But too much carbon dioxide could poison a cell.
