Respiratory System

PROCESS OF  RESPIRATORY SYSTEM

Nose

The nose have two nostrils. The nostrils is a cavity that serves as filter when the air enters out bodies. Have you noticed how hairy our nostrils are? These hairs actually catch dirt and dust particles and clean the air we breathe! When we blow our noses, the snot that comes out is made up of this mucus and the dirt particles.

Mouth

Most of the air we breathe comes through our nose. But, we can also breathe through our mouths to get more air!

Pharynx

The pharynx, or throat, is part of the tube that air will go down to enter our lungs.

Larynx

The larynx is a tube where the vocal cords are locates. Its vibration with the passes of air produce the voice.

Trachea

The windpipe is a long tube that goes down our neck to the lungs. The windpipe’s lining makes mucus, which traps dust and other dirt particles. this mucus towards our throat, where we swallow and digest it.

Bronchi

There are two bronchi. The inner wall has cilia and mocus to filter the air and trap the particles that have been breathed in.

Bronchioles

The bronchioles are like tree-structure. They absorbe air in each lung.

Lungs

Two spongy organs in our chest. Lungs have a lot of little air sacs called alveoli. Tiny blood capillaries run through alveoli. When air reaches the alveoli, it passes into the bloodstream. It is then carried around our entire bodies.
