Respiration

Respiration is the act of respiration:

Respiratory system

The respiratory system is made up of the organs included in the trade of oxygen and carbon dioxide. The respiratory system is split into two areas: the higher respiratory tract and the decrease respiratory tract.

The higher respiratory tract is made up of the:

- Nostril

- Nasal cavity

- Mouth

- Sinuses

- Throat (pharynx)

- Voice field (Larynx)

- Windpipe (trachea)

The decrease respiratory tract is made up of the:

Lungs

The lungs soak up oxygen. Your physique’s cells want oxygen to dwell and perform their regular features. The lungs additionally get rid of carbon dioxide, a waste product of the cells.

The lungs are a pair of cone-shaped organs made up of spongy, pinkish-gray tissue. They take up most of the area in the chest (thorax).

The lungs are surrounded by a membrane (pleura).

The lungs are separated from one another by the mediastinum, an space that accommodates the:

The appropriate lung has three sections, referred to as lobes. The left lung has two lobes. Whenever you breathe in:

- Air enters your physique by your nostril or mouth.

- Air then travels down the throat by the larynx and trachea.

- Air goes into the lungs by tubes referred to as main-stem bronchi.

One main-stem bronchus results in the proper lung and one to the left lung:

- In the lungs, the main-stem bronchi divide into smaller bronchi.

- The smaller bronchi divide into even smaller tubes (bronchioles).

- Bronchioles finish in tiny air sacs (alveoli) the place the trade of oxygen and carbon dioxide happens.
