Question

how is oxygen gas and Carbondioxide gas transported in human being​

Answer 1

Answer:

The two main gases exchanged are oxygen and carbon-dioxide. Oxygen is absorbed by the blood capillaries from the lungs alveoli by diffusion while carbon-dioxide is absorbed by the lungs alveoli from blood capillaries by diffusion. ... Oxygen is transported from lungs to the body cells in the form of oxy-hemoglobin.

Answer 2

Hey friend..

Transport of Oxygen: Haemoglobin transports oxygen molecule to all the body cells for cellular respiration .The haemoglobin pigment present in the blood gets attached to O2 molecules that are obtained from breathing and thus forms oxyhaemoglobin .This oxygenated blood is then distributed to all the body cells by the heart. After giving away O2 to the body cells, blood takes away CO2 which is the end product of cellular respiration and blood becomes de-oxygenated.

Transport of carbon dioxide: Since haemoglobin pigment has less affinity for CO2, CO2 is mainly transported in the dissolved form. This deoxygenated blood gives CO2 to lung alveoli and takes O2 in return.
