      In at least 250, words talk about difference in between an artery and veins.  Also, discuss the importance of the four chambers of the heart.  Respond to two fellow students by Monday.

      Arteries carry blood away from the heart. With the exception of pulmonary blood vessels, arteries carry oxygenated blood, and they have thick walls with muscle tissue. Veins carry deoxygenated blood towards the heart. Veins have thinner walls and use valves to keep our blood flowing. The big difference between them is that arteries carry oxygenated blood to all parts of our body, and veins carry the deoxygenated blood to the heart. We need to discuss about the chambers too. Our heart have four chambers: left and right atrium (upper chambers), and left and right ventricle (lower chambers). About the function,: the lower right chamber pumps the oxygen poor blood to our lungs through the pulmonary artery. The lungs reload blood with oxygen. After the lungs fill blood with oxygen, the pulmonary veins carry the blood to the left atrium. This upper chamber pumps the blood to our left ventricle. This ventricle pumps blood into the aorta, which sends this oxygenated blood to tissues throughout our body.

          Great explanation Yentel. It always helpt to be able to visualize it in your mind so its easier to memorize and understand. If you have a chance check out youtube videos on it and theres is even songs that go with it. Its a fun way to learn about the blood flow as it can get tricky.

          I really enjoyed reading the way you explained the differences in detail about the Arteries, Veins, and four chambers

      The different between arteries and veins are that:
      Arteries carry oxygen-rich blood from the heart to the body, and
      Veins carry oxygen-poor blood back to the heart.
      Our heart is made up of four chambers which include
      1. Right Atrium
      2. Left Atrium
      3. Right Ventricle
      4. Left Ventricle
      These four chambers are located behind and slightly to the left of the breastbone. The heart pumps blood through arteries and veins.
