return blood from capillaries to the heart

what is the primary function of blood

transport oxygen, carbon dioxide, and blood cells. delivers nutrients and hoemones, removes waste products, and assists in tempreture regulation and defense against disease

why is red blood cell color red?

hemoglobin

what is a complex protein that is made up 4 protein strands plus an iron-rich heme group?

hemoglobin

what type of cell defend agqinst diseases by recognixing proteins that do not belong to the body?

white blood cells

white cells

what is a cell fragment used in blood clotting?

platelets

how long is the lifespan of a platelet?

the circulatroy system carries 2 types of blood. what are they?

oxygen rich and oxygen poor

what type of blood

what type of blood is a hhigh oxygen content and low carbon dioxide content?

oxygen rich blood

what type of blood travells away from the body cells

oxygen poor
