The Circulatory System
Also called the circulatory system, it consists of the heart, blood vessels, and blood. It carries needed substances to cells and carries waste products.
The Circulatory System. Function  Consists of the heart and blood vessels  Carries oxygen and nutrients to the body’s cells and remove carbon dioxide.
The Circulatory System. 3 Main Functions 1. Transport Oxygen from lungs 2. Transport Carbon Dioxide to lungs 3. Carry nutrients to body.

Parts, functions and blood flow Circulatory System Parts, functions and blood flow

Blood Nutrients White Blood Cells Red Blood Cells Platelets Plasma

Red: carries oxygen from heart to rest of the body Red/White Blood Cells Red: carries oxygen from heart to rest of the body White: helps protect body against disease and fights infection

Transport System Veins Arteries Capillaries

How is your heart like a swimming pool pump? Each time your heart pumps, it pushes blood through the body…and eventually, the blood circulates back to the heart.

Atrias: Right atrium and Left Atrium Heart Parts….. Vena cava Atrias: Right atrium and Left Atrium Ventricles: Right ventricle and Left Ventricle Pulmonary Artery Pulmonary Vein Aorta

Flow of Blood… Vena Cava Right Atrium Aorta Left Atrium Lungs Right Ventricle Pulmonary Artery Lungs Pulmonary Veins Left Atrium Left Ventricle Aorta Vena Cava

Heart Rate How many times your heart beats per minute RESTING Between 60 and 80 beats per minute WORKING Keep between TARGET HEART RATE & MAXIMUM HEART RATE
