Supply of oxygen for aerobic respiration depends on which combined arrangement?
Answer and explanation
Correct answer: Gas exchange by the respiratory system and transport by blood
Aerobic respiration requires a continuous supply of oxygen to cells. In humans, the respiratory system brings air to the alveoli, where oxygen diffuses into the blood. Haemoglobin in red blood cells then transports that oxygen through the circulatory system to body tissues. Therefore option A correctly combines gas exchange and blood transport; digestion, bile production, and urine storage do not deliver oxygen to cells.
