6. 6 Where Your Heart Is Your Heart is in the centre of your body, behind the breastbone and between your lungs. Your Heart and Lungs fill the chest cavity and are protected by the ribs. Heart Lung Lung

7. 7 What Your Heart Is Your Heart is a pump Your Heart is a muscular organ Your Heart pumps blood all around your body

8. 8 InternalStructure of heart

9. 9 Heart Chambers Your Heart has 4 Chambers: Right Auricle Left Auricle Right VentricleLeft Ventricle TThe bottom chambers are called V_________. TThe top chambers are called A_______.

10. 10 Atriums and Veins: How Blood gets into your Heart Blood enters the Heart through two V____. Right Auricle Left Auricle The Body sends blood with no Oxygen in it through veins to the Heart. Veins The Lungs send blood with Oxygen in it through veins to the Heart.

11. 11 Atriums to Ventricles Blood is pumped from the Auricles into the Heart’s Ventricles. Right Auricle Left Auricle Right VentricleLeft Ventricle

12. 12 Ventricles and Arteries: Pumping Blood from your Heart The Heart pumps blood through Arteries to the Lungs to collect Oxygen. Left VentricleRight Ventricle Artery Blood leaves the Heart through two A_______. The Heart pumps blood through Arteries to supply Oxygen to the Body.

13. 13 Structure of Your Heart: Summary Right Auricle Left Auricle Right Ventricle Left Ventricle From Lungs To Lungs From Body To Body Blood from Veins into Heart Blood to Arteries out of Heart

14. 14 Arteries Arteries are blood vessels that carry blood away from your heart. Arteries are just like tubes Blood is pumped through the arteries at high pressure because it needs to reach every part of your body. To stand the high pressure, arteries have thick walls. Arteries become narrow as they branch through the body to supply all tissues.

15. 15 Veins and Valves Veins are blood vessels that carry blood from body parts to heart Veins, like arteries, Are just like same. Valves in the Veins make sure blood flows in 0ne direction only. The blood pressure is much low in the veins than it is in the arteries so the veins have thin walls. Veins have thin walls and contain valves

16. 16 Capillaries Capillaries receive blood from the smallest arteries and carry it into the tissues. Capillaries are just wide enough to allow one blood cell to pass along. Once the blood is “used”, Capillaries then pass blood on from the tissues to the veins. Capillaries have thin walls to let gases, food, waste and other substances pass between blood and tissues.

17. 17 Blood Blood contains Red & White Cells, Plasma and Platelets. Platelets Red Cells White Cells Plasma Blood carries food, heat and oxygen around the body.
