Circulatory System

Function of the Circulatory System

• Carries nutrients, and oxygen throughout the body
• Picks up waste products and carries them to other systems for removal
• Regulates body temperature
• Carries white blood cells which aid in keeping us healthy

Parts of the Circulatory System

Heart: involuntary muscle that pumps blood through our bodies

Blood Vessels:

• Arteries – carry oxygenated blood away from the heart
• Veins – carry blood back to the heart
• Capillaries – connect arteries to veins, the extremely thin walls allow for gas and nutrient exchange between blood and body cells.

Blood:

• Plasma
• Platelets
• Red Blood Cells
• White Blood Cells
