2. MAJOR FUNCTIONS OF THE CIRCULATORY SYSTEM

3. MAJOR FUNCTION OF THE CIRCULATORY SYSTEM 1.Transports blood, oxygen, and nutrients around the body.

4. MAJOR FUNCTION OF THE CIRCULATORY SYSTEM 1.Transports blood, oxygen, and nutrients around the body. 2.Provides body organs with food.

6. PARTS OF THE CIRCULATORY SYSTEM

7. 1.Heart- It functions to pump blood gathered from the veins and into the arteries around the body.

8. PARTS OF THE CIRCULATORY SYSTEM 1.Heart- It functions to pump blood gathered from the veins and into the arteries around the body. 2.Artery- A blood vessel that lets blood flow from the heart to any part of the body.

11. FUNCTIONS OF THE ORGANS

12. 1.Our hearts work to pump deoxygenated blood from the veins through the the lungs and into the arteries.

13. FUNCTIONS OF THE ORGANS 1.Our hearts work to pump deoxygenated blood from the veins through the the lungs and into the arteries. 2.Our lungs gather that deoxygenated blood pumped from our veins. Our lungs fill that blood with oxygen and gets rid of the excess carbon dioxide.

14. OUR BLOOD

15. Our blood is made of basic components; red blood cells, white blood cells, platelets and plasma.

16. OUR BLOOD Our blood is made of basic components; red blood cells, white blood cells, platelets and plasma. 1.Red blood cells are cells that transport oxygen and carbon dioxide to and from the tissues around our body.

17. OUR BLOOD Our blood is made of basic components; red blood cells, white blood cells, platelets and plasma. 1.Red blood cells are cells that transport oxygen and carbon dioxide to and from the tissues around our body. 2.White blood cells are colorless cells that are a part of our immune system, they protect our body from unwanted microorganisms in our bodies.

20. THE PATH OUR BLOOD TAKES

21. Our blood travels through our body, functioning to get our organs the oxygen and nutrients it needs.

22. THE PATH OUR BLOOD TAKES Our blood travels through our body, functioning to get our organs the oxygen and nutrients it needs. Blood starts when it enters from the right side of the heart through two veins, the superior vena cava and the inferior vena cava. Then it enters the right atrium, when the right atrium contracts, the blood flows to the tricuspid valve and into the right ventricle. From the right ventricle, it goes through the pulmonic valve, and to the pulmonary artery, and towards the lungs. From there it goes to the pulmonary veins and to the left atrium, then through the mitral valve, into the left ventricle, and through the aortic valve. Finally, it reaches the aorta, and from here it circulates around the rest of the body.

23. HOW IT WORKS WITH OTHER SYSTEMS?

24. HOW IT WORKS WITH OTHER SYSTEMS 1.(Respiratory System) The circulatory system gathers the oxygenated blood from the lungs and into the blood stream where it travels to different parts of your body to be exchanged for waste materials.

25. HOW IT WORKS WITH OTHER SYSTEMS 1.(Respiratory System) The circulatory system gathers the oxygenated blood from the lungs and into the blood stream where it travels to different parts of your body to be exchanged for waste materials. 2. (Digestive System) The circulatory system gets the nutrients broken down by the digestive system and delivers it to cells and blood vessels.

26. HOW IT WORKS WITH OTHER SYSTEMS 1.(Respiratory System) The circulatory system gathers the oxygenated blood from the lungs and into the blood stream where it travels to different parts of your body to be exchanged for waste materials. 2. (Digestive System) The circulatory system gets the nutrients broken down by the digestive system and delivers it to cells and blood vessels. 3. (Muscular System) All of the blood vessels in the circulatory system are made up of smooth muscle, and the heart is also a muscle called the cardiac muscle.

27. OVERALL YOUR CIRCULATORY IS THE MOST IMPORTANT OUT OF ALL THE BODY SYSTEMS. All cells need blood to transport oxygen for respiration. Without oxygen, the brain would eventually die. A human can survive without a digestive system, for nutrients can be taken in for your body IV drip. You can also survive without a nervous system. A person can still live, but they would not be able to move, feel, touch, etc.

28. DID YOU KNOW THAT… 1.If you laid out all the veins, arteries, and capillaries, they would wrap around the Earth 2.5 times? 2.A heart can still beat after being removed from a body? 3.A condition called “broken heart syndrome” can temporarily weaken the muscle of the heart? It is often confused for a heartbreak. Basically, someone can break your heart. 4.After 120 days, a red blood cell will die from aging or damage.
