How does the respiratory system work together as a community?

Answer 1

First we breathe in through our nasal/oral cavity. The air travels through our pharynx, then to our layrnx (AKA voice box) then to our trachea, bronchus, bronchioles then to the aveolus (more than one aveoli) This is the LUNG

The individual aveoli's have capillary networks on them which are one cell thick called

epithelial cells. Gas exchange occurs here. The air we breathe in needs to be filtered first (which were filtered earlier by our nasal cavity, trachea, bronchus and bronchioles) then they are moistened slightly by our nasal cavity and the aveoli's that have a very thin layer of water surrounding the interior of the aveoli.

Once the air is filtered it diffuses through the membrane of the aveoli's and the capillaries.

Since diffusion is the movement of particles from a high concentration to a low concentration, Carbon dioxide diffuses into the aveoli and the Oxygen diffuses into the capillary which attaches to the red blood cells. Now called Oxygenated Blood.

The oxygenated blood from the capillary network travels into the Pulmonary Vein. (keep in mind that VEIN's bring blood into heart, this is an exception where the Pulmonary Vein, carries oxygenated blood from lungs to heart)

So as mentioned before the Oxygenated blood from the lungs travel into the Pulmonary Veins which lead into the left atrium of the heart. As the heart beats (AKA contraction of muscle) the oxygenated blood from left atrium travels to the left ventricle to the AORTA, out into the major arteries, and the arterioles

NOTE: words that end in -ioles/-ules are "smaller than"

Veins. Venules - Smaller veins

And so this is the respiratory system working as a community

(SORRY IF IT'S UNCLEAR, I DID MY BEST TO EXPLAIN)
