Respiratory System

The primary function of the respiratory system is to supply the blood with oxygen in order for the blood to deliver oxygen to all parts of the body. The respiratory system does this through breathing. When we breathe, we inhale oxygen and exhale carbon dioxide. This exchange of gases is the respiratory system's means of getting oxygen to the blood.

Nose and mouth

The right lung is divided into three lobes,

The left lung has only 2 lobes

The diaphragm is the main muscle in breathing, and is located underneath of the lungs

Your lungs fill with air

The trachea branches off into two main bronchi, your left and right primary bronchi, which lead to the left and right lung respectively. Trachea is a pipe made up of rings of cartilage

The alveoli are the final branches of the respiratory tree and act as the primary gas exchange units of the lung

Inside the lung, the tubes divide into smaller and smaller tubes called bronchioles. At the end of each of these tubes are small air sacs called alveoli.

Capillaries are small blood vessels with thin walls

capillaries are wrapped around these alveoli. The walls are so thin and close to each other that the air easily seeps through. In this way, oxygen seeps through into the bloodstream and carbon dioxide, in the bloodstream, seeps through into the alveoli, and is then removed from the body when we breathe out.

The diaphragm is the muscle that controls the breathing process. As the diaphragm flattens it causes the chest to expand and air is sucked into the lungs. When the diaphragm relaxes, the chest collapses and the air in the lungs is forced out.

1. Aerobic means (with oxygen). Aerobic exercises strengthen the heart and lungs. These are exercises that require a continuous oxygen supply to the large muscle groups. 2. No SMOKING 3. No harmful FUMES

Lung Cancer Bronchitis Asthma Emphysema Pneumonia

The muscles of the bronchial tubes get tight and thick, making the passage ways inflamed and filled with mucus, making it hard to breathe.

is an inflammation of the bronchial tubes, or bronchi (the air passages that extend from the windpipe into the lungs).

It is believed that emphysema often is a late effect of chronic infection or irritation of the bronchial tubes.

is when the airways react by narrowing or obstructing when they become irritated. This makes it difficult for the air to move in and out

is a general term that refers to an infection of the lungs, which can be caused by a variety of viruses, bacteria, and parasites.

is similar to many other forms of cancer. Cancer, which is the uncontrollable division and replication of cells, usually originates in one part of the body. If left untreated most cancer, including lung cancer, may spread, or metastasize, to other parts of the body.

Both systems need each other in order to function properly!

a system of organs functioning in respiration and in humans consisting especially of the nose, nasal passages, pharynx, larynx, trachea, bronchi, and lungs.

a flap of cartilage at the root of the tongue, which is depressed during swallowing to cover the opening of the windpipe.

a large membranous tube reinforced by rings of cartilage, extending from the larynx to the bronchial tubes and conveying air to and from the lungs; the windpipe

The diaphragm is the main muscle in breathing, and is located underneath of the lungs.

any of the major air passages of the lungs that diverge from the windpipe.
