Vedclass · Answer

(C) $1$. Diffusion alone is insufficient to supply oxygen to all body cells in large, multicellular organisms because the distance between the lungs and the tissues is too great.$2$. Respiratory pigments, such as $hemoglobin$, have a high affinity for oxygen.$3$. They bind with oxygen in the lungs to form $oxyhemoglobin$ and transport it through the blood to tissues where oxygen concentration is low.$4$. They also assist in the transport of $CO_2$ from the tissues back to the lungs for exhalation.$5$. Therefore, respiratory pigments are essential for efficient gas exchange and cellular respiration.
