What system delivers oxygen and nutrients to every cell in the body

The Circulatory or Cardiovascular System

Explanation:

This system allows the circulation of blood to every cells of the body with the transport of oxygen and nutrients essential for its survival. These nutrients include glucose, amino acids, vitamins, minerals and so on produced by the body through metabolism.

The circulatory system comprises also of the lymphatic system, which allows for the flow of lymphs.

The circulatory system is made up of systemic and pulmonary circulation. The heart and blood vessels being the major structures in this circulation. The blood moves to the lungs and get oxygenated (pulmonary circulation) and it then returned back to the heart for transport to other parts of the body known as the systemic circulation. Hemoglobin, which carries oxygen in the blood and also carbon iv oxide for excretion out of the plasma. From the digestive system, the nutrients are absorbed into the blood plasma and then transported for the cell use or for storage.

during the process of dna replication, brdu can replace thymidine and incorporate into the newly synthesized dna, cell proliferation thus can be reflected in the extent of brdu incorporation.
