In a paragraph, describe the function the stomach serves in the digestive system.

The pathway of oxygen in breathing system is started from the nasal cavity. Then to the pharynx, trachea, bronchi and into the lungs before flowing into the bronchioles and alveoli.  And it makes the oxygen that flow inside affect the diaphgram to move down and contracting. Within this point the air pressure is going down.

Further explanation:

Human is one of the most perfect living creatures in terms of anatomy. The human respiratory system is divided into two:

1. The tract of the respiratory
2. Its respiratory mechanism

First, in terms of respiratory tract, it consist of five body parts, Namely the

• nasal cavity,
• pharynx,
• throat (trachea),
• throat (bronchus),
• lungs.

Second, the mechanism is, when we breathe,

1. the air will enter in the sequence of these body parts. Started from the nasal cavity.

2. The oxygen that flow inside makes our diaphgram moves down and contracting. At this point the air pressure is going down.

3. Then to the pharynx, trachea, bronchi and into the lungs before flowing into the bronchioles and alveoli.

4. The Lungs will grow itself to fill more oxygen and carry it to its cylinders or air sacs. In the lungs, precisely in the alveoli sac, oxygen and carbon dioxide exchange. Also, some of it will be blended in circulatory system to move toward becoming or make oxygenated blood. It will venture out up to the Capillaries and dump off Carbon Dioxide. Toward the end, we will make exhalation of Carbon Dioxide(CO2).

Additional information:

In the human body, there are two stages of breathing, namely external and internal, with two cycles of continuous alternation of inspiration and expiration.

When your friend does inspiration, the diaphragm muscle will rise, so that air from outside enters the lungs. While during expiration, the diaphragm muscle will drop, which makes the air from the lungs out.
