Respiratory/Circulatory Project

An oxygen molecule is two oxygen atoms stuck together.

Has the ability to form compounds with almost all other elements.

atomic number of 8 and atomic mass of 15.9994 amu.

Symbol O Important element of atmosphere and is

nessarcy for any life on earth. Oxygen is important for all life because it

gives oxgen to cells so they can be created and make ATP.

What is an Oxygen Molecule

The Respiratory System

The oxygen molecule is in the air.

It travels into your mouth

It travels down into the trachea past the larynx

It goes through the bronchi tube. Then enters the lungs

Once in the lungs, it enters separate branches called the bronchioles

They end up in the aveolies

Oxygen transfers into blood through capillaries

It then enters the circulatory system

The Circulatory SystemWhen the blood cell is in the heart, the left ventricle contracts.

The blood is pushed into the aorta.

From the aorta, they enter a series of arteries

They then reach the capillaries

Once in the capillaries, the oxygen molecules detach from the blood cells

The oxygen molecules go through the capillary walls

They then enter the body tissue

The blood finds its way to the heart

It goes through the veins to reach the right atrium

It enters the right ventricle

It goes through the pulmonary arteries and ends up in the lungs

The blood then recycles

However the oxygen molecule has a different path than the blood.

The ddetached oxygen molecule finds it way to the Mitchondria

In the Mitcochondria Cellualr Resperation occurs

Oxygen is convered to carbon dioxcide and ATP is made

The now carbon dixocide molecule travels back through the body

It is pumped out of the lungs and back out through the mouth into the air
