The smallest blood vessels of the body = capillaries
It diffuses into the blood capillaries surrounding the alveoli.
capillaries
alveoli, arteries, anus, arm and ankle
your lungs have structures called alveoli. The alveoli are surrounded by capillary beds which carry blood. The oxygen enters the alveoli when you inhale. The oxygen then diffuses from high concentration in your alveoli to low concentration the blood in the capillaries surrounding the alveoli.
In the capillaries surrounding the alveoli in the lungs
They are present in the lung surrounding the alveoli.
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.
The alveoli is the division of the respiratory system where gas exchange with the blood occurs. Oxygen from the inhaled air diffuses into the blood in the capillaries surrounding the alveoli, while carbon dioxide diffuses from the blood into the alveoli to be exhaled.
The respiratory and circulatory systems are involved in the exchange of gases between the alveoli and blood. The alveoli are part of the lungs, and their surrounding capillaries are part of the circulatory system.
