Front Back
Blood
The fluid tissue of the body contained within the curculatory system
Plasma

Red blood cells
Cells in the blood containing hemoglobin; carry oxygen
Hemoglobin
Iron containing molecule in red blood cells; used in transporting oxygen
White blood cells
Colorless blood cell that protects the body from infection
Platelets
Cell fragments in the blood; help form blood clots
Antibodies
Produced by white blood cells to help fight infection
Heart
A muscular organ that pumps blood
Atriums
The two upper chambers of the heart. Atriums are the chambers that recieve blood coming from other parts of the body. The Left atrium receives oxygen-rich blood from the lungs, and the right atrium recieves blood high in waste products from the rest of the body.
Ventricles
The lower chambers of the heart. Ventricles pump blood away from the heart, either to the lungs or to the rest of the body. The right ventricle pumps blood to the lungs where it can absorb oxygen and get rid of the CO2 waste it has picked up. The left ventricle, the strongest chamber of your heart, pumps blood to the rest of the body.
Valves
Flap-like structures in the heart that close to prevent blood from flowing backwards
Arteries
Blood vessels that move blood away from the heart to the lungs or body
Capillaries
Microscopic blood vessels that connect arteries and veins. This is where the blood gives the oxygen it is carrying to the cells of your body and picks up carbon dioxide waste from the cells to deposit at your lungs. The walls of the capillaries are very thin so that materials can be exchanged easily.
Veins
Blood vessels that move blood toward the heart from the lungs or the body
Pulmonary circulation
The flow of blood between the heart and lungs (ex: pulmonary arteries carry blood to the lungs and pulmonary veins carry it back to the heart)
