--The circulatory system, is the transportation system of the body.
--The major structures that make this possible are the heart, blood vessels and blood.
--The heart pumps  blood in order to move nutrients oxygen, carbon dioxide disease-fighting white blood cells, and hormones to and from the cells in the body
--The circulatory system has two main types of circulation, pulmonary whichis to the lungs and systemic.
--Pulmonary circulation travels from heart to the lung where your blood pick up oxygen and back to the heart.
--Systemic circulation is from the heart to the body
--Your heart has four chambers that is used to pump blood throughout your body.
--The top chambers are called atria and the bottom chambers are the ventricles.
--Arteries carry blood away from the heart and veins carry blood towards the heart
--Veins carry blood towards the heart.
--Capillaries, which are the smallest blood vessels in the body create a network of vessels connecting veins and arteries.
--You have around 1.5 gallons of blood in your body
-- Your blood is composed of several different types of cells.
 --Red blood cells help carry oxygen.
--White blood cell and help fight pathogens.
--Platelets help create blood clots.
--These blood cells are found in a liquid called plasma which consists of water along with electrolytes and some proteins and hormones

In summary, The job of the circulatory system is to circulate blood to and from cells in the body in order to transport nutrients and oxygen and remove carbon dioxide and waste.
