How is oxygen and carbondioxide transported in han beings????
Answers
Oxygen and carbon dioxide are transported in human being through blood
Answer:
Via blood
Explanation:
It contains haemoglobin-a pigment which is a globular protein comtaing a haem(or an iron)group.the gasses are transported too each cell via capillaries.in the capillaries, as they are one cell thick, the gases can diffuse easily from he capillaries into the cell.the gases move from higher concentration to lower concentration.when the cell needs oxygen, and carbon dioxide is given as a byproduct of resporation, the oxygen concentration in the cell decreases and the carbon dioxide concentration in the cell increases.so carbon dioxide diffuses into the blood and oxygen diffuses into the cell.now in the blood the carbon dioxide is high and the oxygen is low, such blood is called deoxygenated blood. This blood is transported to the lungs, where, in the alveoli diffusion takes place again.oxygen rich blood is then gained and the cycle repeats
