Cardiovascular system

    Cards (99)

    • Types of blood vessels

      • Artery
      • Vein
      • Capillary
    • Artery
      • Carries oxygenated blood
    • Vein
      • Carries deoxygenated blood
    • Capillary
      • Allows diffusion into muscles
    • Valve
      • Prevents backflow
    • Arteriole
      • Carries oxygenated blood
    • Venule

      • Carries deoxygenated blood
    • Pathway of blood through the heart

      1. Left side of heart receives deoxygenated blood
      2. Right side of heart pumps oxygenated blood
      3. Oxygenated blood enters through pulmonary vein and exits through aorta
      4. Deoxygenated blood enters through pulmonary artery and exits through lungs
    • Main blood vessels in the heart

      • Vena cava
      • Aorta
      • Pulmonary vein
      • Pulmonary artery
    • Double circulatory system

      • Pulmonary system (heart to lungs)
      • Systemic system (heart to working muscles)
    • Heart rate
      Amount of times our heart beats per minute
    • Stroke volume
      Volume of blood pumped per contraction
    • Cardiac output
      Amount of blood pumped per minute
    • Red blood cell
      Carries oxygen around the body to different parts
    • Haemoglobin
      Chemical on red blood cell that binds oxygen
    • Red blood cell
      Carries carbon dioxide to the lungs to be breathed out
    • Pathway of blood to working muscles

      1. Blood exits aorta
      2. Enters artery
      3. Travels to part of body
      4. Enters arteriole
      5. Enters capillary
      6. Diffusion of oxygen into muscles
    • Pathway of blood from muscles to lungs

      1. Blood becomes deoxygenated
      2. Enters venule
      3. Enters vein
      4. Travels back to heart
      5. Enters pulmonary vein
      6. Exits heart through pulmonary artery
      7. Gets reoxygenated in lungs
    • Vein
      • Low pressure
      • Have valves
      • Have elastic walls to allow high volumes
    • Artery
      • High pressure
      • Have thick walls
    • Capillary
      • One cell thick to facilitate diffusion
    • Cardiovascular endurance
    • Cardio
      Relating to the heart
    • Vascular
      Relating to blood vessels
    • Vessel
      A tube that carries blood
    • Oxygen
      A gas carried in the blood
    • Carbon Dioxide
      A waste product of respiration
    • Respiration
      The process of making energy
    • Haemoglobin
      A small protein inside red blood cells that enables them to carry oxygen
    • Antigen
      A substance that causes the body to make an immune response against it
    • Myoclonus
      Sudden, brief involuntary jerking of a muscle; muscle twitching
    • Something that carries something
      Carried or transported in red blood cells to organs and muscles
    • What waste product?
      Carbon dioxide from respiration
    • Components of CV System

      • Blood
      • Blood vessels
      • Heart
    • Blood
      Made up of 4 different components: red blood cells, white blood cells, plasma, platelets
    • Red Blood Cells

      They contain haemoglobin, transport oxygen to working muscles, transport carbon dioxide to the lungs
    • Red Blood Cells
      • Their disc shape allows for better oxygen carrying capacity
    • White Blood Cells

      Fight infection
    • Platelets
      Help clot blood, create a mesh to prevent blood from leaking out
    • Plasma
      A transport medium, mostly water
