The human respiratory system is a series of organs responsible for taking in oxygen and expelling carbon dioxide.

This picture shows main parts of the Respiratory System.

There are 3 main parts, the airway, the lungs, and

the muscles of respiration.

Other systems

Pharynx

Larynx

For the digestive system, its muscular walls function in the process of swallowing, and it serves as a pathway for the movement of food from the mouth to the esophagus.

Mouth

Allowing air to pass through it while keeping food and drink from blocking the airway. The larynx is also the body's “voice box” as it contains the vocal folds that produce the sounds of speech and singing.

Name, title

The mouth works with the respatory system by how you take in the oxeygen. Air comes into the body through the nose or mouth, and enters the airways. Airways are the tubes that carry air into our lungs.

The trachea is a wide, hollow tube that connects the larynx (or voice box) to the bronchi of the lungs. It is an integral part of the body's airway and has the vital function of providing air flow to and from the lungs for respiration

Functions of the Respiratory system

Functions of the system

The human respiratory system is a series of organs responsible for taking in oxygen and expelling carbon dioxide. The primary organs of the respiratory system are lungs, which carry out this exchange of gases as we breathe

Functions of the system

Functions of this system:

Respiration, oxygen from incoming air enters the blood, and carbon dioxide, a waste gas from the metabolism, leaves the blood. A reduced lung function means that the ability of lungs to exchange gases is reduced.

  • In pulmonary ventilation, air is inhaled through the nasal and oral cavities (the nose and mouth). It moves through the pharynx, larynx, and trachea into the lungs.
  • Oxygen from inhaled air diffuses from the alveoli into pulmonary capillaries surrounding them. It binds to hemoglobin molecules in red blood cells, and is pumped through the bloodstream.
  • The bloodstream delivers oxygen to cells and removes waste carbon dioxide through internal respiration
  • Phonation is the creation of sound by structures in the upper respiratory tract of the respiratory system. During exhalation, air passes from the lungs through the larynx, or “voice box.”
  • The process of olfaction begins with olfactory fibers that line the nasal cavities inside the nose. As air enters the cavities, some chemicals in the air bind to and activate nervous system receptors on the cilia.

Illustration of parts:

The gas exchange process is performed by the lungs and respiratory system. Air, a mix of oxygen and other gases, is inhaled. In the throat, the trachea, or windpipe, filters the air.

Diseases of the system:

Asthma:

Asthma is a condition in which your airways narrow and swell and produce extra mucus. This can make breathing difficult and trigger coughing, wheezing and shortness of breath. For some people, asthma is a minor nuisance.

Lung cancer:

Asthma is a condition in which your airways narrow and swell and produce extra mucus. This can make breathing difficult and trigger coughing, wheezing and shortness of breath. For some people, asthma is a minor nuisance.

Facts:

A person usually breathes an average of 13 pints of air every minute.

2. Lungs aren’t the same size. To accommodate the heart, the right lung is larger than the left lung — for humans, that is.

3. Lungs float on water. It’s not something most people are aware of but, actually, the lungs are the only organs in the human body that are capable of floating on water.
