1. Circulatory System

2. Circulatory System works like roads in the body – Works with Respiratory System to deliver Oxygen and remove Carbon Dioxide – Works with Digestive System to deliver Nutrients – Works with Urinary to remove nitrogen waste – Works with Endocrine System to deliver hormones Works with all systems! Circulatory System = Transportation System

3. Pulmonary- “Of the lungs”, vessels going to and from the lungs. Veins – carry blood towards the heart Arteries- Carry blood away from the heart Capillaries- small blood vessels where O 2 is given to cells and CO 2 waste is picked up Types of Blood Vessels

4. Anatomy of Heart and Blood Vessels

5. Movement of oxygenated and deoxygenated blood

6. Heart Diagram: Flow of Blood 1. Pulmonary vein-takes oxygenated blood from lungs to left side of heart 2. Left Atrium 3. Left Ventricle- pumps blood out to the rest of body 4. Aorta –largest artery takes blood away from heart

7. 5. Vena cava: largest vein, carries Deoxygenated blood back to the heart on the right side 6. Right Atrium 7. Right Ventricle- pumps blood to the lungs 8. Pulmonary artery-takes deoxygenated blood to lungs

8. Blood vessels are made up of different tissue types: Muscle tissue allows the blood vessels to dilate and constrict. Excess fat tissue can narrow the opening of the blood vessel and affect blood flow.

9. Platelets: Cells that binds to injury site to trap blood and begin to rebuild/repair the injury.
