In the diagram, part 11 corresponds to the pulmonary alveoli, which is where the gas exchange occurs, given that they are surrounded by capillaries and the oxygen and carbon dioxide can diffuse between the capillaries and the alveoli.

So, capillaries are the part of the circulatory system that interacts with alveoli.

The types of respiration in humans are:

• Pulmonary ventilation,: the process of, taking air in and out of the lungs, (inhalation and exhalation). ,This involves the nasal cavity, pharynx, larynx, trachea, bronchi, bronchioles, alveoli, and lungs, as well as the diaphragm (structures 1 to 11)

,

• External respiration ,is the ,gas exchange, that, occurs in the alveoli (structure 11),, where the carbon dioxide diffuses from the blood cells in the capillaries to the alveoli, and the oxygen goes from the alveoli to the capillaries.

,

• Internal respiration ,is the exchange of oxygen and carbon dioxide that occurs ,between the blood cells and all the other cells in the body,.

,

• Cellular respiration, is the set of metabolic reactions that takes place in the mitochondria of each cell to break glucose to obtain energy in the form of ATP, which requires the presence of oxygen.
