Yes it does.
to allow gas exchange (oxygen and carbon dioxide)
They exchange them through spiracles.
Two ways in which the structure of a capillary is adapted to its function is to encourage the exchange of oxygen. Another reason is to encourage the exchange of carbon dioxide.
Capillaries cover the alveoli in order to maximize the area for gas exchange between the lungs and the blood. Carbon dioxide is released from the blood through the capillary walls and into the alveoli, while oxygen is picked up from the alveoli through the capillary walls and into the blood.
Capillaries are the thin-walled vessels that allow oxygen and carbon dioxide exchange. Their thin walls make it easy for gases to diffuse across the membranes.
They exchange them through spiracles.
The capillary bed in the lungs is where the oxygen and carbon dioxide are exchanged.
Oxygen is delivered to, and carbon dioxide is removed from, cells near the capillary.
A tiny, thin-walled, capillary-rich sac in the lungs where the exchange of oxygen and carbon dioxide takes place.
External Respiration is where gasses are absorbed into the blood through the alveolar capillary beds. Internal respiration is where the gasses are transferred into the cells from the blood.
