Essentially the air inhaled, which includes oxygen, passes through the various bronchi and briochioles until it reaches the aveoli. Here is where oxygen diffuses due to a concentration gradient. The oxygen must diffuse 5 layers before it enters a red blood cell. The red blood cell can now deliver it to tissues. At the same time, carbon dioxide diffuses through 5 layers to reach the aveolar space and can be exhaled the 5 layers are as follows: (1) type 1 aveolar cell, (2) basal lamina of type 1 aveolar cell, (3) basal lamina of endothelial cell, (4) endothelial cell, and (5) plasma membrane of the red blood cell. Oxygen diffuses from 1 to 5 and Carbon dioxide difuses from 5 to 1. Oxygen and carbon dioxide are essentially trading places. Note: basal lamina is connective tissue that a cell adheres to. Bronchi and bronchioles are the tubes which air flows. aveoli are small sacs of empty space, which is the site for gas exchange. drazx is the original author of this answer

Were does carbodioxide you breathe out came from?

when you breath in oxygen, it goes through the bronchi in your lungs, through the bronchioles and then to the alveoli from there it goes to the capillaries where the oxygen dissolves into the blood through tissue that is one cell thick. as that happens, the carbon dioxide that is in your blood already, dissolves out into the alveoli. then it travels through the bronchioles, bronchi, and to your lungs, then out your nose.


What is the order of the structures that oxygen passes through between your nose?

Oxygen enters your nose,then goes through the trachea,to the bronchi,and last to your lungs.


How is the respiratory system able to supply blood with oxygen?

Oxygen is inhaled through the mouth and nose, travels through the trachea and bronchi and into the lungs. From there it goes into the alveoli and diffuses through the capillaries. It attaches to haemoglobin in the blood.


Where does oxygen go after entering the nose or mouth?

Oxygen travels down the windpipe (trachea) and enters the lungs, where it moves into the bloodstream through tiny blood vessels called capillaries. From there, the oxygen is transported by red blood cells to all the cells in the body where it is used for energy production through the process of cellular respiration.


What gas is needed to stay alive?

The gas you need to stay alive is Oxygen, you need oxygen to carry vital functions of body, when you inhale oxygen, its goes directly into the lungs and through alveolis, which are present in lungs oxygen get absorbed into blood which is then taken to heart and heart pumps the blood to each and every part and organ of the body, so like this your body works.

Where does get its oxygen?

the oxygen in your blood comes from the air you breath in . It goes in through your mouth into the lungs and the oxygen gets taken out from the lungs into the cappilaries.


What is blood before it goes to the lungs?

Blood goes to the lungs oxygen poor and comes out of the lungs oxygen rich.


When blood enters the left ventricle is the blood high in oxygen or low in oxygen?

Oxygen goes from the muscles to the right atrium, from there it goes to the right ventricle and into the lungs then it passes from the lungs to through the left atrium and into the left ventricle where it is recirculated through the body.


Where does oxygen blood go after leaving the lungs?

it goes through and around your body!


When the oxygen goes into the bloodstream it goes into arteries veins or capillaries?

Oxygen moves into the lungs to the alveoli in the lungs into capillaries into pulmonary veins to the heart then to arteries that go through the rest of the body.


What happens to most of the air you breath into your lungs?

we breath in mostly oxygen when we breath and when that oxygen goes to our lungs it goes through the bronchi and into little air sacs called alveoli the oxygen then moves into the blood going into the red blood cells while at the same time carbon dioxide moves out of the blood and comes out of body as exhales air


Why does oxygen enter the lungs?

Because you suck in air through your mouth or nose and it goes into your lungs... it's called breathing =)


What do amphibians breathe through?

Amphibians breath through their skin. They take in oxygen through their moist skin and it goes to their lungs.


How does oxygen travel through your body starting from the nasal cavity?

It goes to your lungs just like all other air.when air goes into any body part it always goes to your lungs.And oxygen isn't in the air,carbon dioxide is.

How does oxygen enter your body?

Oxygen (O2) enters your body through breathing air, which contains oxygen in it. This oxygen goes into your lungs where it is put into the bloodstream, supplied to cells in your body, returned to the lungs as carbon dioxide (CO2), and exhaled through the lungs.


What happens to oxygen after it has been used by your body?

Oxygen that has been used by your body during respiration is converted into carbon dioxide as a waste product. The carbon dioxide is then transported back to the lungs, where it is exhaled out of the body when you breathe.
