1. PUMP IT UP AND LET IT FLOW How the circulatory system work QUARTER 1 / WEEK 2

2. OBJECTIVES: 1.) To identify the Parts and Functions of the Circulatory System. 2.) To explain the process of the Circulatory S ystem and its importance. 3.) Why the Circulatory S ytem and R espiratory S ystem work together.

3. Circulatory System - Is one of the mechanisms in the body that facilitates the nourishment of cells with the various nutrients and essential elements introduced into our body through the food that we eat and the air we breathe.

4. Illustration of circulatory system

5. Circulatory System - It is comparable to a complex arrangement of Metropolitan highways that connect all destinations of cells in the body thus providing the cells the much needed provisions for its sustainability.

6. Circulatory System - Together with the respiratory system , it circulates important materials vital to life to all cells in the body and at the same time excrete metabolic wastes away from the body. This system is also known as the CARDIOVASCULAR SYSTEM.

7. The Big Three 1.) The Heart 2.) The Blood Vessels 3.) The Blood

8. 1.) The Heart - The heart is a hollow muscle , as big as your fist which is located in the center of your chest between the lungs. It is a double pump that pumps on both left and right sides. It has for distinct chambers, two chambers on each side the atrium and ventricle. - The upper chambers are the atria and the lower chambers are the ventricles . The atria are the receiving chambers of the heart accepting blood from the body (right atrium) and from the lungs (left atrium).

9. Illustration of The heart

10. 1.) The Heart - The ventricles are the pumping chambers, moving blood to the lungs (right ventricle), and to the different parts of the body (left ventricle). The heart has valves between its upper and lower chambers that serves as one-way door regulating the flow of blood inside the heart thus preventing the blood from flowing backwards.

11. 2 .) The Blood Vessels - Also known as veins or arteries - It carries the blood throughout the body. - And to also remove waste products from your body.

12. 2 .) The Blood Vessels The Artery – it carries oxygenated blood away from the heart to cells tissues, and organs in the body.

13. 2 .) The Blood Vessels The Veins – it carries deoxygenated blood or blood carrying CO2 from the body to heart to expelled to the lungs.

14. 2 .) The Blood Vessels Capillaries – the smallest blood vessels in the body connecting the smallest arteries and veins.

15. 3.) The Blood - The blood carries the essential materials throughout the body, which is primarily compose of blood cells (45%) and plasma (55%).

16. 3.) The Blood Red Blood cells (erythrocytes) – characterized by red pigmentation due to haemoglobin.

17. 3.) The Blood White Blood cells (leukocytes) – functions for body defense . They fight infections by engulfing Bacteria and other microorganisms that enter the body, foreign proteins and etc.

18. 3.) The Blood White Blood cells (leukocytes) – Antibodies produced by lymphocytes a type of WBC act against foreign materials.

19. 3.) The Blood White Blood cells (leukocytes) – Antigens are materials that causes the body to produce antibodies.

20. Circulations In The Body 1.) Pulmonary Circulation 2.) Systemic Circulation 3.) Coronary Circulation

21. Pulmonary Circulation - deoxygenated blood moves away from the right ventricle to the lungs via the Pulmonary artery, and returns oxygenated blood to the left atrium and ventricle of the heart.

22. Systemic Circulation - Oxygen-rich blood from the lungs move passing through the pulmonary vein and enters the left atrium of the heart and goes to the left ventricle.

23. Systemic Circulation - From the left ventricle, it pumps blood through the arteries via the aorta, to the capillaries in the tissues of the body and picks up waste materials and CO2.

24. Coronary Circulation - Coronary arteries supply oxygenated blood to the heart muscle, and cardiac veins, Drain away the blood once it has been deoxygenated.
