B) W astes
C) Hormones
D) Heat energy

Accepted Answer

Bacteria are not a principal category of things transported by the cardiovascular system. While bacteria can enter the bloodstream, their presence is typically indicative of an infection or disease, rather than a normal function of the cardiovascular system. The system primarily transports nutrients, wastes, hormones, and heat energy as part of its normal physiological functions.
