1 Circulatory System

2 Functions Transportation of food, water, oxygen, and other materials to cells Elimination of carbon dioxide and other waste materials from cells

3 Circulatory System Organs The Heart – muscle that pushes blood through the body The human heart has 4 chambers 2 atria – upper chambers 2 ventricles – lower chambers Blood Vessels – blood travels through them arteries – carry blood away from the heart veins – carry blood to the heart capillaries – tiny blood vessels that deliver supplies to individual cells

4 Diseases/Disorders of the Circulatory System Hypertension Atherosclerosis Heart Attack Stroke Heart Failure

5 Circulatory System & Homeostasis Works with the respiratory system to deliver oxygen and remove carbon dioxide. Works with the digestive system to deliver nutrients Works with the nervous system to regulate your heartbeat

6 Functions of Blood Transportation – carries materials throughout the body Protection – Some blood cells help fight infection Temperature Regulation – helps regulate body temperature by expanding or contracting near surface to release heat.

7 Parts of Blood Red Blood Cells – deliver oxygen to the cells White Blood Cells – protect your body from infection Platelets – stop bleeding Plasma – liquid part of the blood
