Unit b section - 3.3 circulatory system

  1. 1.  This system is responsible for delivering nutrients absorbed by the digestive system to each cell in your body. It is your bodies transportation network. It also is responsible for delivering the oxygen and wastes created by the respiratory system.
  2. 2.  Your circulatory system acts similar to the a highway interchange; ◦ Your body has different routes to take to reach different areas ◦ Oxygen-rich blood flows one way, CO2 rich blood travels the other ◦ There are larger systems closer to the main area than the remote areas of the body
  3. 3.  The most important part of the system The heart is A PUMP, did you know it is actually two pumps? The right and left side are each a separate pump that work together
  4. 4.  The right side of the heart pumps blood to your lungs ◦ Here it receives fresh oxygen and gives CO2 The left side of your heart receives this oxygen-rich blood from your lungs and pumps it to all the rest of your body The blood returns to the right side to begin all over again
  5. 5.  There 2 atriums and 2 ventricles in the heartAtriums Receive blood from veins ◦ Right Atrium – receives blood low in oxygen from the body and pumps it into the right ventricle ◦ Left Atrium – Receives oxygen-rich blood from the lungs and pumps it into the left ventricle
  6. 6. Ventricles Are the bottom two chambers of the heart that receive blood from the atriums Pushes blood out through arteries ◦ Right Ventricle – when it contracts it pumps blood to the lungs ◦ Left Ventricle – When it contracts it pumps blood to the body
  7. 7.  The aorta is a three hole artery that carries the blood from the heart to the entire body This is the major tube that carries all of the bodies blood to the areas that need it
  8. 8.  Made up of 3 of the 4 types of tissue; ◦ Connective on the outside (Tough) ◦ Muscle in the middle (Very strong and elastic) ◦ Epithelial on the inside
  9. 9.  Inside the body there is an intricate network of blood vessels These vessels are about 100,000km in length if completely stretched out
  10. 10.  Inside the body the blood vessels that are responsible for carrying blood away from the heart. These blood vessels are called ARTERIES. They carry blood from the heart to both the lungs and the rest of the body
  11. 11.  Have a thick muscular layer in the middle that expands and contracts to help push blood along When you feel the expansion of the arteries this is commonly known as PULSE
  12. 12.  Inside the body the blood vessels that are responsible for carrying blood towards the heart. These blood vessels are called Veins. They carry blood from rest of the body and the lungs to your heart
  13. 13.  Veins are thinner than arteries, and have valves that stop the blood from flowing backwards
  14. 14.  Are tiny blood vessels whose purpose is the diffusion of nutrients and gases Are located between arteries and veins They have two adaptations; ◦ 1) Epithelial tissues that are only one cell thick ◦ 2) Are very narrow so that blood cells have to pass through single file
  15. 15.  Diffusion -- transports oxygen from your blood into your cells, and carbon dioxide from your cells into your blood Osmosis – Transports water in and out of the blood cell
  16. 16.  Is the second largest example of connective tissue ◦ (bones are the largest) Blood is composed of; ◦ Red Blood Cells ◦ White Blood Cells ◦ Platelets (tiny cells) ◦ Plasma (liquid portion) Plasma makes up 55% of blood, everything else makes up 45%
  17. 17.  High specialized in order to perform their function ◦ Function is to carry oxygen RBC’s do not have a nuclei, therefore have more room for oxygen ◦ Are extremely flexible – can bend and twist through the small capillary spaces
  18. 18.  Specialized cells to fight infection Some are capable or eating bacteria at infection sites such as cuts
  19. 19.  Are cells that help to stop the bleeding at cutsPLASMA The liquid portion of your blood, transports nutrients to your cells and carries wastes, such as carbon dioxide, away
