  • transports substances in the body
• components of blood

  1. RBC or red blood cells contain a pigment called hemoglobin that transports oxygen
  2. WBC or white blood cells fight against germs and protect us from diseases
  3. platelets help in clotting blood
  4. plasma is the fluid part

• blood vessels

  • tube like structures that transport blood
  • supplies food, water, oxygen to the body and removes waste products from the body

• arteries

  • carry blood with oxygen from heart to body
  • have thick walls because blood pressure is high
  • narrow for blood to flow fast
  • doesnt contain valves because bloods flows in the right direction due to pumping of heart

  • doesnt contain valves because bloods flows in the right direction due to pumping of heart
• pulmonary arteries

  • connects heart to lungs
  • carry blood with less oxygen (deoxygenated blood) from heart to lungs
• pulmonary arteries

  • connects heart to lungs
  • carry blood with less oxygen (deoxygenated blood) from heart to lungs
• veins

  • carry blood with co2 from organs to heart
  • have thin walls because blood pressure is low
  • wider than arteries
  • contain valves that prevent blood from flowing in the opposite direction
• veins

  • carry blood with co2 from organs to heart
  • have thin walls because blood pressure is low
  • wider than arteries
  • contain valves that prevent blood from flowing in the opposite direction
• pulmonary veins

  • connects lungs to heart
  • carry blood with oxygen from lungs to heart
• pulmonary veins

  • connects lungs to heart
  • carry blood with oxygen from lungs to heart
• capillaries

  • small blood vessels
  • arteries divide themselves into carpillaries
  • arteries deliver oxygenated blood to tissues
  • capillaries take deoxygenated blood from tissues to veins

• heart

  • pumps blood in blood vessels
  • located in chest cavity
  • roughly the size of a first
• heart

  • pumps blood in blood vessels
  • located in chest cavity
  • roughly the size of a first
• sections of a heart

  • has 4 chambers
  • upper 2 chambers is atria, lower 2 chambers is ventricles
  • the part between chambers help avoid mixing of oxygenated blood and blood with co2
