Human Transport System

• The main parts of the circulatory system are the heart, blood vessels and blood
• The heart is a pumping organ that drives blood around the body, as well as contains nodes and valves
• The heart has four chambers: right atrium, left atrium, right ventricle and left ventricle
• There are three types of blood vessels: the arteries veins and capillaries
• The arteries are the blood vessels that carry oxygenated blood away from the heart
• The veins are the blood vessels that carry deoxygenated blood towards the heart
• The capillaries are the blood vessels that connect the arteries and the veins
• The blood is a fluid that carries oxygen and nutrients around the body
• The blood is made up of four main components: plasma, red blood cell, white blood cell and patelets
• The plasma is made up of mostly water and protein, being some of the nutrient being transported around the body
• The white blood cell is part of the immune system, mostly activated when you have an illness
• The red blood cell is the largest cell in the body and transports oxygen around the body
• The pulmonary circulation starts from:

  1. Right Atrium
  2. Right Ventricle
  3. Pulmonary Arteries
  4. Lungs
  5. Pulmonary Veins
  6. Left Atrium
• The systemic circulation starts from:

  1. Left Ventricle
  2. Aorta
  3. Body Parts ( any )
  4. Superior or Inferior vena cavae
  5. Back to the Right Atrium
• The blood above the heart goes to the superior vena cavae, while the blood below goes to the inferior vena cavae
