Question

blood transports oxygen and nutrients to cells for cellular respiration, and 1 point removes wastes. evaluate the necessity of this transport function by considering the fate of a cell if the circulatory system failed in its transport role. the cell would rapidly cease to function because it would be unable to obtain necessary reactants (like oxygen) and simultaneously be poisoned by the buildup of metabolic wastes (like carbon dioxide). the cell would primarily be vulnerable to bacterial infection, as the failure of the circulatory system would immediately disable the white blood cells. the cell would increase its production of hemoglobin to absorb oxygen directly from surrounding tissues, maintaining normal function. the cell would switch to performing photosynthesis to generate its own oxygen and glucose, eventually adapting to the loss of blood flow.

Explanation:

Cells need oxygen and nutrients for cellular respiration and need to get rid of waste products. Without the circulatory - system's transport function, cells can't get reactants like oxygen and will be poisoned by waste like carbon - dioxide. White blood cells are not immediately disabled by circulatory system failure. Cells can't increase hemoglobin production to absorb oxygen directly from tissues to maintain normal function, and animal cells can't perform photosynthesis.

Answer:

The cell would rapidly cease to function because it would be unable to obtain necessary reactants (like oxygen) and simultaneously be poisoned by the buildup of metabolic wastes (like carbon dioxide).
