Presentation Transcript

  1. Circulatory/ Cardiovascular System

  2. Circulatory System (aka: Cardiovascular System) Function: Carries needed substances to cells and carries wastes away from cells. BrainPop Video – Circulatory System

  3. Organs • Heart • Hollow, muscular organ that pumps blood throughout the body. BrainPop Video - Heart

  4. Path of Blood Through the Heart

  5. Organs – Blood Vessels • Arteries • Blood vessel that carries oxygen-rich blood away from the heart and to the body parts. • Capillaries • Small blood vessels where materials are exchanged between the blood and the body’s cells (oxygen & carbon dioxide) • Veins • Carries oxygen-poor blood (w/carbon dioxide) back to the heart (to be pumped out to the lungs)

  6. Flow of Blood Through the Body

  7. Blood Vessels

  8. Blood • Blood is made of 4 components (parts): • Plasma – liquid part of blood • Red blood cells – take up oxygen in the lungs and deliver it to cells • White blood cells – the body’s disease fighters (part of immune system) • Platelets – cell fragments used in forming blood clots (that make scabs) BrainPop Video - Blood
