CARDIOVASCULAR SYSTEM KEY TERMS

Learn about the key terms and functions related to the cardiovascular system, including the heart, arteries, veins, capillaries, blood cells, and more. Explore how oxygen and carbon dioxide are transported, and the role of circulation within the body.

  1. CARDIOVASCULARSYSTEMKEY TERMS

  2. Cardiovascular System Key Terms FRONT BACK Having to do with the Heart • Cardio/Cardiac

  3. Cardiovascular System Key Terms FRONT BACK Muscular organ responsible for pumping blood throughout the body Size of your fist • HEART

  4. Cardiovascular System Key Terms FRONT BACK Upper chambers of the heart (2) • ATRIUM

  5. Cardiovascular System Key Terms FRONT BACK Lower chambers of the heart (2) • VENTRICLES

  6. Cardiovascular System Key Terms FRONT BACK Flap-like structures found between the atrium and the ventricle They are responsible for the “Lub-dub” sound of your heartbeat when they close • VALVES

  7. Cardiovascular System Key Terms FRONT BACK Tissue separating the chambers of the heart (also between your nostrils) • SEPTUM • (See yellow part of your model)

  8. Cardiovascular System Key Terms FRONT BACK Carry blood AWAY from the heart In the BODY, they carry oxygen –RICH blood • ARTERIES

  9. Cardiovascular System Key Terms FRONT BACK Carry blood TOWARD the heart In the BODY, they carry oxygen –POOR blood, carbon dioxide, and waste products. • VEINS

  10. Cardiovascular System Key Terms FRONT BACK Tiny blood vessels that allow the exchange of gases and waste products between the blood and the body cells Connect the arteries and the veins A  C  V  C  A • CAPILLARIES

  11. Cardiovascular System Key Terms FRONT BACK Responsible for transporting oxygen, carbon dioxide, and other waste products • RED BLOOD CELLS

  12. Cardiovascular System Key Terms FRONT BACK Responsible for fighting disease • WHITE BLOOD CELLS

  13. Cardiovascular System Key Terms FRONT BACK Clot together to stop bleeding (scabs) • PLATELETS

  14. Cardiovascular System Key Terms FRONT BACK Liquid portion of the blood, in which the RBC, WBC, and platelets are suspended Like the liquid in a snowglobe • PLASMA

  15. Cardiovascular System Key Terms FRONT BACK The system of specialized tubes that transport material (blood) from one part of the body to another Veins, arteries, & capillaries • VASCULAR

  16. Cardiovascular System Key Terms FRONT BACK Organs where oxygen (O2) is inhaled and carbon dioxide (CO2) is exhaled in/out of the body • LUNGS (pulmonary)

  17. Cardiovascular System Key Terms FRONT BACK Does not occur in the lungs!!! Occurs at the cell level Capillaries exchange oxygen and carbon dioxide with individual cells in the body. • RESPIRATION

  18. Cardiovascular System Key Terms FRONT BACK The main source of energy for cells The necessary product for respiration Inhale Lungs Blood  Cell • OXYGEN

  19. Cardiovascular System Key Terms FRONT BACK The main WASTE product of respiration Cell Blood HeartLungs  Exhaled • CARBON DIOXIDE

  20. Cardiovascular System Key Terms FRONT BACK Left/Right Lung Artery Brings Oxygen-POOR blood AWAY from the Heart TO the Lungs • PULMONARY ARTERY

  21. Cardiovascular System Key Terms FRONT BACK Right/Left Lung Vein Brings Oxygen-RICH blood TOWARDS the Heart from the Lungs • PULMONARY VEIN

  22. Cardiovascular System Key Terms FRONT BACK The LARGEST artery Transports Oxygen-RICH blood from the lungs  heart  out to the body • AORTA

  23. Cardiovascular System Key Terms FRONT BACK Transports Oxygen-POOR blood from the body back to the heart Superior/Upper Vena Cava – transports blood from the upper body Inferior/Lower Vena Cava – transports blood from the lower body • VENA CAVA

  24. Cardiovascular System Key Terms FRONT BACK The circulation of blood between your heart and your lungs O2 POOR blood goes from the heart  to the lungs  Drops off CO2 and waste products/Picks up O2  goes back to the Heart • PULMONARY CIRCULATION

  25. Cardiovascular System Key Terms FRONT BACK The circulation of blood between your heart and your BODY O2 RICH blood goes from the heart  out to the BODY  Drops off O2 and Picks up CO2 and waste products goes back to the Heart • SYSTEMIC CIRCULATION
