Let's Understand The Working Of the Respiratory System!

Humans breathe to survive. The main purpose of the respiratory system is to supply oxygen to different sections of the human body with the help of blood. During the respiration procedure, various organs like the nose, trachea, lungs, and diaphragm play a vital role.


Maximum air that a human breathes ensues from the nose and hence it is an important organ for respiration. Nose hairs help in filtering and purifying the contaminants present in the air that we inhale. The important function of the nose is that it acts as the temperature to maintain the device. Mucous which is secreted by the nose helps in lubricating and moistening the nose. Hence, the air that a human inhale is always purified before it reaches the lungs.

It is an 11cm long tube that begins from the larynx and continues to the fifth vertebrae present in the chest cavity. Tiny hairs are present in the inner membrane of the trachea that helps in trapping and removing small hairs. It is protected with the help of a c-shaped ring-like structure. The walls of the trachea consist of four layers that are the mucosa, submucosa, hyaline cartilage, and adventitia.


Pleural membrane is a double-layered membrane that protects the lungs. The upper layer is known as the parietal pleural that encloses the thoracic cavity wall and the other deep layer is known as the visceral pleural that encloses the lungs. The space between two pleura that is visceral and parietal is known as the pleural cavity. Respiratory system homework help USA will explain you deeply about the working of lungs through self-explanatory diagrams and also offer round the clock service with regards to solving your problems.

The functional unit of the lungs is the alveoli. There are two kinds of cells present over the wall of alveoli. Type 1 alveolar epithelial cells are thin and support the exchange of gases with the help of the capillary membrane. Type 2 alveolar epithelial cells are round and cubical. They contain microvilli that produce alveolar liquid. The exchange of gas like carbon dioxide and oxygen between the blood and alveoli takes place through the process of diffusion.

Basic Steps of Respiration:

The exchange of gas in the human body takes place through three basic steps:

Breathing or respiratory volume:

It is measured as the amount of air inspired or expired per minute which is equal to the respiratory rate per minute into tidal volume.

Pulmonary respiration:

The exchange of gas across the respiratory membrane between the blood in pulmonary capillaries and alveoli of the lungs.

Internal or tissue respiration:

It is stated as the exchange of gases through blood present in systemic capillaries. In this type of respiration, the supply of oxygen is done from the capillaries to the tissues and carbon dioxide enters into the capillaries through tissues. Cellular respiration is defined as the production of ATP molecules during the metabolic exchange between oxygen and carbon dioxide. Therefore, the sum of inspiration and expiration equal to respiration.
