Human circulatory system-
human circulatory system consist of blood, lymph, blood vessels and heart
in heart-------
the blood flows into the right auricle through the superior and inferior venacava. the blood then moves towards the right ventricle and then to the lungs through the pulmonary artery and then the deoxygented blood exchanges with the oxygenated blood in the lungs and then comes back to the left auricle through pulmonary vein and then to theleft ventricle and then to the whole body through the aorta.
When the muscles of all four chambers of heart are relaxed,the pulmonary veins bring oxygenated blood from lungs to left atrium of the heart. When left atrium contracts the blood moves to left ventricle. Further when the left ventricle contracts,the oxygenated blood is forced into aorta. The main artery carries oxygenated blood to all parts of the body and at thhe same time, CO2 which is a waste product is released during respiration enters the blood. Capillaries finally results to form vena cava that bring de-oxygenated blood to the right auricle and when the right atrium contracts blood reaches right ventricle. And when the right ventricle contracts blood through pulmonary artery reaches lungs for oxygenation.
hope this helps :)

Answer:
=======
The circulatory system is made up of blood vessels that carry blood away from and towards the heart. Arteries carry blood away from the heart and veinscarry blood back to the heart.
The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide. These roadways travel in one direction only, to keep things going where they should.
What Are the Parts of the Circulatory System?
--------------------------------
Two pathways come from the heart:
• The pulmonary circulation is a short loop from the heart to the lungs and back again.
• The systemic circulation carries blood from the heart to all the other parts of the body and back again.
