Inhalation

Inhalation is the process of breathing in, during which air is taken into the lungs. It is a vital part of the respiratory system, and is essential for the survival of all aerobic organisms, including humans.

Process

During inhalation, the diaphragm contracts and moves downward, increasing the space in the chest cavity. The intercostal muscles between the ribs also help enlarge the chest cavity. This decrease in pressure allows air to flow into the lungs.

Role in Health and Disease

Inhalation plays a crucial role in the body's ability to deliver oxygen to the cells and remove carbon dioxide. It is also the first step in the process of gas exchange, which occurs in the alveoli of the lungs.

Inhalation can also be a route of exposure to environmental pollutants and toxins, which can lead to respiratory diseases such as asthma, bronchitis, and lung cancer.

Inhalation Therapy

Inhalation therapy is a form of treatment that delivers medication directly to the lungs. This can be particularly effective for respiratory diseases, as it allows for a higher concentration of medication to reach the affected area than would be possible with systemic administration.
