Cardiovascular system

    Cards (33)

    • What is the main function of the circulatory system mentioned in the video?
      To transport glucose and gases around the body
    • What color is human blood?
      Red
    • Why do veins and arteries appear blue or red in diagrams?
      To indicate lower or higher concentrations of oxygen
    • What is the reason veins may appear blue or green under the skin?
      It involves the way they appear under the skin
    • What are some functions of human blood?
      Maintains pH, temperature, osmotic pressure, and transports hormones, nutrients, and gases
    • What is plasma in blood?
      The liquid portion of blood containing water, proteins, salts, and lipids
    • What are the cellular components of blood?
      Red blood cells, white blood cells, and platelets
    • What is the role of red blood cells?
      To transport gases
    • What do white blood cells do?
      They fight infections
    • What are platelets?
      Cellular fragments involved in blood clotting
    • What protein gives red blood cells their color?
      Hemoglobin
    • How is the human heart anatomically divided?
      Into a deoxygenated partition and an oxygenated partition
    • What do arteries generally do?
      Carry blood away from the heart
    • What do veins generally do?
      Carry blood to the heart
    • Where does oxygen delivery occur in the circulatory system?
      At the capillary level
    • What are the four chambers of the heart?
      Right atrium, right ventricle, left atrium, left ventricle
    • How can you remember the position of the atria and ventricles in the heart?
      A comes before V in the alphabet, so atria are at the top
    • What is the function of heart valves?
      To separate chambers and prevent backflow of blood
    • What is the pathway of deoxygenated blood starting from a human toe?
      It travels through the inferior vena cava to the right atrium
    • What happens to deoxygenated blood in the lungs?
      It takes on oxygen and releases carbon dioxide
    • What is the major artery that carries oxygenated blood throughout the body?
      The aorta
    • How does the heart receive its own blood supply?
      Through coronary arteries
    • What do coronary veins do?
      They take deoxygenated blood to the right atrium
    • Can you trace the pathway of blood through the heart?
      Right atrium, tricuspid valve, right ventricle, pulmonary valve, pulmonary artery, lungs, pulmonary vein, left atrium, mitral valve, left ventricle, aortic valve, aorta
    • How many times does a human heart beat in a day?
      Over 100,000 times
    • What is the cardiac cycle?
      The coordinated sequence of the heart’s contractions and relaxations
    • What are some treatment options for heart conditions?
      Medications or surgery
    • What are the components of blood and their functions?
      • Plasma: Liquid portion containing water, proteins, salts, lipids
      • Red blood cells: Transport gases
      • White blood cells: Fight infections
      • Platelets: Help with blood clotting
    • What is the pathway of blood through the heart?
      1. Right atrium
      2. Tricuspid valve
      3. Right ventricle
      4. Pulmonary valve
      5. Pulmonary artery
      6. Lungs
      7. Pulmonary vein
      8. Left atrium
      9. Mitral valve (bicuspid valve)
      10. Left ventricle
      11. Aortic valve
      12. Aorta
    • What are the major functions of the circulatory system?
      • Transport of nutrients and gases
      • Regulation of body temperature
      • Maintenance of pH and osmotic pressure
    • What are the types of blood vessels and their functions?
      • Arteries: Carry blood away from the heart
      • Veins: Carry blood to the heart
      • Capillaries: Exchange of gases and nutrients at the tissue level
    • What are the heart's chambers and their roles?
      • Right atrium: Receives deoxygenated blood
      • Right ventricle: Pumps deoxygenated blood to lungs
      • Left atrium: Receives oxygenated blood
      • Left ventricle: Pumps oxygenated blood to the body
    • What are coronary arteries and veins?

      • Coronary arteries: Supply oxygenated blood to the heart
      • Coronary veins: Return deoxygenated blood to the right atrium
