No. The capillaries are part of the circulatory system.
Your lungs, the diaphragm, alveoli, bronchi, and capillaries are all in the respiratory system
Circulatory system AND THE RESPIRATORY SYSTEM
the respiratory system
Human respiratory system contain wind pipe or trachea, bronchus, bronchi, alveoli with blood capillaries. Lungs have air sacs or alveoli which are surrounded by capillaries which oxygenate, de-oxygenated blood.
The respiratory and circulatory system connect in the lungs. At the alveoli, the air sacs are wrapped closely by capillaries to facilitate gas exchange.
Gas exchange occurs in the alveoli in the respiratory system. The thin-walled structures allow diffusion of gases into and out of the capillaries.
I would have to say both the minute capillaries and the mucosa.
The primary system to get rid of CO2 is the respiratory system. But it is aided by the circulatory system which delivers CO2 to the aveoli, where hemoglobin on Red blood cells then picks up O2 to take back to the cells.
The respiratory system brings in air containing oxygen, and the oxygen is absorbed by the circulatory system. Capillaries surrounding the alveoli absorb inhaled oxygen into the blood.
the important organ in the respiratory system would be the lungs. There are many other organs that are just as important as the lungs such as diaphram, capillaries, etc. but the lungs are considered to be the "stars"
