oxygen passes from the air to the blood, where it binds with haemoglobin to form oxyheamoglobin (how it is carried around the bloodstream)
Carbon dioxide passes (diffuses) the other way ie. from blood to air inside alveolus, and from there exhaled.
Lungs
Air passes through your nose and mouth and into your windpipe, also known as the trachea, which carries the air to your lungs for breathing.
Carbon dioxide does no pass from the nose to the blood stream. CO2 is a toxin which can cause the body significant harm and so to take it in from the air would be very counterproductive. It is realeased from the blood stream through the cappillariy endothelial cell, interstitial fluid and finally alveaolar cell into the lumen (space inside) of the lung. From the alvelus it passes through the bronchiole into the bronchiolar tree until it reaches the primary bronchus. From here the CO2 passes into the trachea then the through the larynx into the pharynx and finally into the nasal cavity and out through the nostril.
Blood loses oxygen as it passes through the capillaries in the body's tissues. Oxygen is delivered to the tissues by red blood cells, which release oxygen molecules into the surrounding cells for cellular respiration. This process occurs in various organs and tissues throughout the body, allowing cells to produce energy for their functions.
In mammals the lungs transfer oxygen from the air into the mammal's blood. The air flows down through a network of bronchial tubes that divide the airflow into smaller and smaller streams. Finally these streams enter the Avioli, which are small sacs with coated in capillaries (blood vessels who's walls are only one or two cells thick). Then the oxygen passes through the capillaries' membrane and into the blood where it is absorbed by the Hemoglobin in the red blood cells.Also, through the reverse process carbon dioxide is expelled from the blood.

Oxygen passes from the air sacs in the lungs to the blood in the capillaries, carbon dioxide passes the other way.
It goes into your lungs which absorb oxygen from it and expell carbon dioxide and then you breath it out. The oxygen goes into your blood to fuel everything in your body. it ends up in your lungs Pharynx--> Larynx--> Trachea--> Bronchus--> Bronchiole--> Aveolus--> Lung
Oxygen
The temperature of the air is regulated by the blood vessels in your nasal passages. As the air passes over these blood vessels, heat from the blood warms the air before it enters your lungs. This helps to keep the sensitive tissues in your respiratory system from being damaged by cold air.
It doesn't. But the body is able to extract oxygen from the air and into the blood through the thin walls of the inside structyre of the lungs. It also rids itseld of carbon dioxide by dumping it back into the air through the membranes.
Because we need to,our lungs needs so does our blood needs oxygen. Let me explain to you (what i remember from bio class) There r "ballon" like things in our lungs which holds the air air and passes it to our heart and our heart passes it to our blood
Yes, the vessels inside your nose warm the air you inhale.
Alveolar interstitial cell wall
The main purpose of this is to get oxygen into the cells of the body where it can be used in the process of respiration to generate energy from glucose. Other chemicals such as nicotine can also easily pass through the thin walls of these air sacs (aveoli) as can viruses and microorganisms. Hope that helps Diesel 'Danger' Nutkins
