Science

• The Circulatory System, also known as the "Transportation System" delivers oxygen and nutrients to cells and takes away wastes.
• The heart in the Circulatory System is like an engine, pumping blood all over the body.
• Blood vessels are like roads that carry blood throughout the body.
• Veins are thin-walled blood vessels that return blood back to the heart.
• Arteries are large blood vessels that take blood from the heart to different parts of the body.
• Capillaries are like small lanes where oxygen and nutrients enter cells and waste products leave them.
• Oxygenated Blood carries oxygen to the body's organs and tissues.
• The Atrium receives the blood, while the Ventricle pumps the blood.
• Deoxygenated Blood is pumped by the right ventricle into the pulmonary artery, which takes it to the lungs.
• The platelets are responsible of stopping us from bleeding whenever we get a cut.
• The white blood cells protect your body from infection.
