The nitrogenous waste products and CO2 accumulate in the blood when the heart is unable to pump blood efficiently.
OXYGEN
The right atrium is where the blood enters the heart.
Venous return (VR) is the flow of blood back to the heart. Arteries takes oxygenated blood away from the heart to the body and veins Cary the blood back to the heart and lungs for disposal of CO2 among other things.
No the cranium is above the heart so therefore the heart is not superior to the cranium.
It's referred to as Carbon dioxide. It is the main cellular waste product that is carried in the blood to the lungs through the heart.

yes heat is a waste product
Oxygen comes out as waste product in plants during photosynthesis
Carbon dioxide is a waste product to humans and animals. Trees "breath" carbon dioxide and oxygen is their waste product (during daytime). Animals and humans breath oxygen and breath out carbon dioxide. When our cells circulate, they go through the pulmonary artery to the lungs and collect oxygen. They then go back through the heart and out into the rest of our body. Cells bring oxygen to the parts of our body that need it. Their waste is carbon dioxide which is exhaled.
Waste Product
the are 3 different respirations but in aerobic the waste product is C02 in anaerobic the waste product from the muscles is lactic acid.
Yes, feces can be considered a waste product.
