RESPIRATORY SYSTEM
PRIMARY FUNCTION ?
- to supply the blood with O2 in order for the blood to deliver oxygen to all parts of the body. O2 is used in the creation of energy through the process of respiration.
- responsible for getting rid of CO2 and water.
CO2 , water = waste products of respiration and are exhaled.

Lungs
soft tissue organs where the oxygen, carbon dioxide gas exchange takes place

ALVEOLI +++
The lungs’ microscopic air sacs, alveoli, are elastic, thin-walled structures arranged in clumps at the ends of respiratory bronchioles.
They resemble bunches of grapes, although the alveoli are partly merged with each other.
White blood cells known as macrophages are always present on their inner surfaces, where they ingest and destroy airborne irritants such as bacteria, chemicals, and dust.
Around the alveoli are networks of capillaries. Oxygen passes from the air in the alveoli into the blood by diffusion through the alveolar and capillary walls
Carbon dioxide diffuses from blood into the alveoli. There are more than 300 million alveoli in both lungs, providing a huge surface area for gas exchange – about 40 times greater than the body’s outer surface.
