Functions Transportation of food, water, oxygen, and other materials to cells Elimination of carbon dioxide and other waste materials from cells
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
Diseases/Disorders of the Circulatory System Hypertension Atherosclerosis Heart Attack Stroke Heart Failure
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
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.
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
