Detailed explanation-1: -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 veins carry blood back to the heart. The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide.

Detailed explanation-2: -Blood comes into the right atrium from the body, moves into the right ventricle and is pushed into the pulmonary arteries in the lungs. After picking up oxygen, the blood travels back to the heart through the pulmonary veins into the left atrium, to the left ventricle and out to the body’s tissues through the aorta.

Detailed explanation-3: -The pulmonary artery branches into the right and left pulmonary arteries carrying blood to the lungs. Blood is oxygenated in the lungs and returns to the heart through the pulmonary veins. The pulmonary veins take the blood to the left atrium.

Detailed explanation-4: -arteries-they carry oxygen-rich blood from your heart to all parts of your body, getting smaller as they get further away from the heart.

Detailed explanation-5: -The arteries carry blood away from the heart; the veins carry it back to the heart. The system of blood vessels resembles a tree: The “trunk” – the main artery (aorta) – branches into large arteries, which lead to smaller and smaller vessels.
