biochemical processes such as glycolysis
What is external respiration?
normal respiration e.g. breathing
what is the pulmonary circulation
It includes lungs and the air and blood delivered to it, does not include heart
what is included in systemic circulation
heat and tissues
What is the function of the pulmonary artery?
carries deoxygenated blood to the lungs from the heart
What is the function of the pulmonary vein?
carries oxygenated blood to the heart from the lungs
What is exchange phase 1,2 and 3
1- air from the atmosphere to lungs
2- from lungs to blood
3 - between blood and cells
how much gas is exchanged in the lungs each minute for
1.CO2
2. O2
1.200
2.250

connecting point of airway of the mouth and nose, also dampens the air
trachea made up of
