circulatory system

• Circulatory system carries blood around the body. It consists of the heart and the blood vessels running through the entire body.
• The circulatory system is responsible for what?

  It is responsible for nutrients, gases, wastes, and hormones.
• There are four chambers of the heart; right atrium, right ventricle, left atrium and left ventricle.
• Oxygenated blood is rich in oxygen but is low on carbon dioxide content.
• Deoxygenated blood is low in oxygen but is high on carbon dioxide content.
• Heart pumps blood throughout the body. The blood pumped by your heart gives your body the oxygen and nutrients it needs to function.
• Right atrium receives blood from the body.
• Left atrium receives blood from the lungs.
• Right ventricle pumps blood from the heart to the lungs for oxygenation
• Left ventricle pumps blood from the heart to the rest of the body

• Blood vessels are the blood that flows through tubes.
• Arteries are blood coming from the heart, it is oxygenated except for the pulmonary artery.
• Veins bring blood to the heart from the body and have a thinner wall than arteries.
• Capillaries are tiny blood vessels that connect the arteries to the veins.
• Pulmonary circulation transports deoxygenated blood from the heart to the lungs. Main function is to oxygenate blood.
• Systemic circulations carries oxygenated blood from the heart to the organs and tissues.
