The circulatory system carries blood cells which are produced mainly by red marrow found in the flat bones, such as the pelvic bones, sternum, ribs, skull vertebrae, and long bones: femur, humerus etc
The Circulatory System circulates blood throughout the body. This blood has red blood cells that carry oxygen. When you are exercising, your heart beats faster to get more oxygen to the cells. This lets the blood travel faster, delivering more oxygen, which when received by cells is used by the mitochondria (the energy source of cells) to produce energy.
The bone marrow is the body's source for blood cells. It is a spongy tissue found in the center of bones where blood cell production, including red blood cells, white blood cells, and platelets, occurs.
The blood
The cardiovascular system, specifically the bone marrow within the skeletal system, produces most of the blood cells for the body. Stem cells in the bone marrow differentiate into red blood cells, white blood cells, and platelets, which are essential components of blood.
Circulatory system
The bloodstream carries nutrients to the body's cells. Nutrients from the food we eat are absorbed in the digestive system and then transported via the bloodstream to cells throughout the body, providing them with the necessary energy and building blocks for proper functioning.
The circulatory system, which includes the heart, blood vessels, and blood, transports glucose and other substances in the blood to the cells of the body. Blood is pumped by the heart through the blood vessels to reach different parts of the body and deliver essential nutrients like glucose.
White blood cells are located in the bloodstream and lymphatic system.
Red blood cells carry oxygen to the body cells via the circulatory system.

The cardiovascular system is primarily responsible for carrying nutrients to body cells. This system includes the heart, blood vessels, and blood. Nutrients are transported in the blood to the body cells where they can be used for energy, growth, and repair.
