How is o2and co2 transported in human beings
Answers
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: through transportation system of veins arteries capillaries heart and lungs
Explanation: when we inhale we take oxygen rich air in and lungs take that oxygen and transfers it to blood through alveoli and made oxy-haemoglobin then throuh pulmonary vein... It is reached to heart and then through aorta (largest artery) it is transported to body parts... Then body parts return co2 in form of carboxy-haemoglobin through veins (vena cava) and then to heart and then heart transers that de-oxygenated blood to lungs through pulmonary artery and then we exhale out co2
