Blood flows from body through Veins 2. Into Right Atrium 3. Into Right Ventricle 4. Through Pulmonary Artery 5. To Lungs 6. Back to Heart through Pulmonary Vein 7. Into Left Atrium 8. Into Left Ventricle 9. Out to body through Artery 10. Gas exchange (O2 and CO2) at capillaries Memory Tricks Arteries = flow A-Away from the heart Veins = think of the V like an arrow shape pointing to the heart Capillaries = gets a couple other blood vessels to join together (biggest word but smallest blood vessel) Osmosis is diffusion through a membrane Diffusion is the movement of molecules from an area of high concentration to an area of low concentration Hemoglobin (ironcontaining protein in red blood cells) carries oxygen Sickle Cell Anemia (recessive genetic disease) results in cresent-shaped red blood cells that do not carry oxygen as well Red Blood Cells White Blood Cells Plasma Platelets
