Detailed explanation-1: -The circulatory system (cardiovascular system) pumps blood from the heart to the lungs to get oxygen. The heart then sends oxygenated blood through arteries to the rest of the body. The veins carry oxygen-poor blood back to the heart to start the circulation process over.
Detailed explanation-2: -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-3: -The heart is a pump, usually beating about 60 to 100 times per minute. With each heartbeat, the heart sends blood throughout our bodies, carrying oxygen to every cell. After delivering the oxygen, the blood returns to the heart. The heart then sends the blood to the lungs to pick up more oxygen.
Detailed explanation-4: -Functions of blood and circulation: Circulates OXYGEN and removes Carbon Dioxide. Provides cells with NUTRIENTS. Removes the waste products of metabolism to the excretory organs for disposal. Protects the body against disease and infection.
