The main role that the heart plays during physical activity is to increase its rate during activity, so that the muscles are more rapidly supplied with oxygen, and so that the waste products are more rapidly carried to the kidneys and liver for processing.
The structures that eliminate wastes are the kidneys, ureters, urinary bladder, and urethra.
The kidneys filter blood to eliminate wastes and to maintain the chemical balance of blood. The ureters is a passage for urine to get to the bladder.
Protists eliminate wastes by allowing them to diffuse through the cell membrane.

Conyx
The heart beats faster in order to eliminate extra waste. This usually occurs while active, like exercise for example. Notice how you have an increased heart-rate? That's because the muscles (such as your heart) need to work overtime to pump blood that carry nutrients to the heart, and the waste away from the heart. This process needs to occur more rapidly when active, thus the heart works faster.
Yes, all living creatures eliminate wastes.

ATP
It helps you eliminate wastes (for example: excess Nitrogen) from the body.
Water, bacteria, puss, digested food remains.
allowing them to diffuse into the water that passes through sponge
foods contain enzymes and bacteria that help digest food and eliminate wastes.
