How do the organs of the respiratory system work?

Answer 1

Basically, the respiratory system works like transport system. As you breath oxygen is transported through the airways to the circulatory system. The circulatory system then delivers carbon dioxide back to the lungs to be breathed back out.

Answer 3

as oxygen enters the mouth and nose, it travels down the trachea. it then moves into one of two bronchi that then delivers it to each lung. the diaphragm helps the lungs expand and fill with oxygen as this is happening. the bronchi branch off into alveoli and then directly in to the bloodstream. the red blood cells drop off the oxygen and pick up the carbon dioxide that needs to leave the body. the carbon dioxide travels back out through to bronchi , trachea , and finally, through to nose and mouth.

Answer 4

Basically, the respiratory system is the system of the body that governs the intake and outflow of oxygen and carbon dioxide in the body. The breath enters the nasal cavity passes through the pharynx then over the larynx the epiglottis (which covers the opening to the larynx when food passes through the pharynx and keeps it from entering the larynx or voice box). The air enters the bronchi which soon splits to right left and the air enters the bronchioles and travels to the alveoli where there is a gas exchange.

Answer 5

Your respiratory system includes the mouth, trachea, main bronchus, bronchi, lungs, bronchioles, and aveoli or air sacs within the lungs. The diaphragm and muscles of respiration are also involved, as is the brain and the heart. Of these, the only ones considered "organs" are the lungs, heart, and brain.

The process of respiration is partly involuntary, and partly voluntary. In healthy persons, the brain stem and brain react to increasing levels of carbon dioxide (CO2), forcing a human to take a breath. This is a feedback system. Note: In chronic lung diseases such as emphysema, this feedback system is reversed: the person's brain becomes accustomed to higher CO2 levels and can die if they are placed on too much oxygen (O2).

When breath is triggered, air is brought through the nose, mouth, or both. It is warmed in the nose, brought down the throat / trachea, and into the main brochus, which splits into the right bronchus and left broncus. In the lungs, it resembles an upside-down tree, with the main bronchus as a "trunk". The two bronchi further "branch" into the bronchioles, which end at the aveoli. There exchange of CO2 and O2 occurs.

At the same time, the de-oxygenated blood from all body areas has returned to the heart. It is sent through the arteries into the lungs, where the CO2 is "dropped off" to the aveloi. The aveoli "pick up" the fresh air containing oxygen, and transfers the O2 onto hemoglobin. Hemoglobin (Hbg) molecules are attached to every Red Blood Cell (RBC). The Hemoglobin (Hbg) on the RBC which are all part of normal blood is then carried back to the heart where it pumped out from the heart to the body and brain.

At the cellular level, blood carries nutrients and O2 to awaiting cells. The work done by the cells produce "by products" and chemical "waste" which is then exchanged between the blood and the cells. The blood now becomes known as venous blood or de-oxgenated blood, because it dropped off the oxygen and now conveys cellular waste including CO2.

The venous blood returns to the heart where it again is filtered through / by the lungs to get rid of CO2 and pick up O2. The brain has signaled the need for a new breath.... And the cycle begins once more.

Humans also have partial voluntary control over respirations. For example, you can take rapid or shallow breaths; or you can hold your breath for a time. But, the involuntary control overrides the voluntary control in healthy persons, and re-establishes a normal respiratory pattern.
