No, red blood cells are not part of the immune system. The immune system is made up of organs, cells, and proteins that work together to fight off infections and diseases. Red blood cells are responsible for carrying oxygen around the body.
Blood cells are made in the spleen and in the bone marrow.
Blood is made up of blood cells. It's kind of self explanatory.

No. The circulatory system is made up of the heart and all the blood vessels.
Blood cells are made in bone marrow.
Red blood cells and white blood cells belong to the circulatory system. White cells are also found in the lymphatic system and are important in the immune response. Red blood cells are also found in the spleen. The spleen breaks down old red blood cells and recycles them and acts as a reservoir for red blood cells when excess bleeding occurs.
The heart, blood vessels, and blood cells are parts of the cardiovascular system.
No, not all cells in the circulatory system are blood cells. The circulatory system also includes blood vessels like arteries, veins, and capillaries that transport blood throughout the body. Blood cells are a component of the blood itself, along with plasma.
The marrow helps in the production of red blood cells and some types of white blood cells in the skeletal system.
