The alveoli and capillaries in the lungs pass oxygen to the blood. Both have very thin walls, which allow the oxygen to pass from the alveoli to the blood. The capillaries then connect to larger blood vessels, called veins, which bring the oxygenated blood from the lungs to the heart.

Where does blood and fluid exchange occur?

The blood enters the capillaries in single file ( capillaries have very small diameter so blood flow through them as in single line) there by diffusion the food passes towards the cell and waste from the blood enter the blood stream

What organ does oxygen travel through everyday?

Every organ in the body! No single cell, tissue or organ can survive for very long at all without a constant supply of oxygen. Blood containing oxygen is continually being pumped from the heart to every cell in the body. As the oxygenated blood passes through the body, the oxygen molecules are used up, it then returns to the heart which pumps it to the lungs to be reoxygenated so that the cycle can start all over again.


Are capillaries connected to the heart?

yes capillaries are connected to heart because heart is a muscular organ and the exchange of materials between heart walls and blood occurs through capillaries.

Organ that gets oxygen into the blood?

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.


What organ does oxygen pass from into the capillaries?

I believe its the alveoli in the lungs. These alveoli provide a large surface area for gaseous exchange.
