1. The Circulatory System (Cardiovascular)

2. Cardiovascular System Includes your heart, blood and vessels Includes your heart, blood and vessels Bring Oxygen and Nutrients to the body and removes waste. Bring Oxygen and Nutrients to the body and removes waste.

3. HEART Made of cardiac muscle Made of cardiac muscle –a. Right atrium – receives blood from whole body –b. Left atrium  Receives blood from lungs –c. Right ventricle –  pumps blood to lungs –d. Left ventricle  Pumps blood to the body

4. Heart Valves – one way and separate the atrium from ventricle to prevent blood backflow Valves – one way and separate the atrium from ventricle to prevent blood backflow The wall separates the two sides of the heart to prevent OXYGENATED blood from mixing with deoxygenated blood.

6. Types of Circulation Coronary – to and from the heart Coronary – to and from the heart Pulmonary – to and from lungs Pulmonary – to and from lungs Systemic – to and from the body Systemic – to and from the body

7. Blood vessels Artery – takes blood away from heart (red) Artery – takes blood away from heart (red) Vein – takes blood to the heart. (blue) Vein – takes blood to the heart. (blue) Capillaries – microscopic vessels where arteries and veins meet (purple) Capillaries – microscopic vessels where arteries and veins meet (purple)

8. Parts of Blood White blood cells – fights infection White blood cells – fights infection Red blood cells – carry oxygen (hemoglobin) Red blood cells – carry oxygen (hemoglobin) Platelets – clot the blood Platelets – clot the blood Plasma – nutrients and minerals Plasma – nutrients and minerals
