They are called alveoli
The capillary net rould the alveoli.
The lungs. Oxygen enters our lungs as part of the air that we breathe. It goes to the blood vessels deep in our lungs and then on to all parts of our body.
Lungs
Heart has two sides (4chambers) separated by a septum.One side it collects the impure blood ie from all the parts of our body and pumps it to lungs. At lungs through alveoli the co2 diffuses out and oxygen enters the blood. this pure blood (oxygenated blood) enters the other side of heart from where it is pumped to all body parts AND cycle continues.
Oxygen reaches all parts of an animal's body when it enters the lungs and is carried by the circulatory system, specifically hemoglobin in red blood cells. The oxygen is then delivered to tissues and cells through blood vessels, where it is used in the process of cellular respiration to produce energy.
the avioli in your lungs carry oxygen to blood cells. Blood then carries the oxygen to other parts of the body viz veins and arteries.
Oxygen is needed by every cell of the body for respiration to release energy. The blood carries the oxygen from the lungs to all parts of the body.
When you breathe in through your mouth or nose, oxygen in the air travels down your windpipe (trachea) and enters your lungs. In your lungs, oxygen is transferred into the bloodstream via tiny blood vessels called capillaries, where it is then carried to all parts of your body to support cellular functions.

Oxygen circulates through the body in blood. A molecule of oxygen (O2) from the lungs binds loosely to a molecule of hemoglobin in a red blood cell. The red blood cell travels through the capillaries and the oxygen molecule is released from the hemoglobin and is delivered to the cells.
The circulatory system is comprised of the heart, lungs and blood vessels. Simply, de-oxygenated blood enters the heart and goes to the lungs via the pulmonary vein. In the lungs is where blood picks up oxygen through diffusion with the alveoli. Oxygen, what we breathe in, is diffused for carbon dioxide, what we breathe out and other wastes. The oxygen rich blood then comes back to the heart via the pulmonary artery and then leaves the heart to supply oxygen to all parts of the body.
