  • Blood that is high on carbon dioxide enters the right atrium and passes through the
    the pulmonary artery
    gas exchange
    the pulmonary circuit
    right ventricle
  • Allows for the exchange of nutrients, gases, and waste products in the body´s cells
    the left ventricle
    the systemic circulation
    the aorta
    the right atrium
  • There are two chambers on the left of the heart:
    the left atrium and the left ventricle
    the right atrium and the right ventricle
  • Arteries and veins become smaller and smaller until they become:
    red blood cells
    arteries
    capillaries
    veins
  • When cells carry out their functions, they produce ______ that pass into the blood.
    right atrium
    waste products
    systemic circulation
    left ventricle
  • the heart, sending blood around the body through the blood vessels acts as a:
    veins
    red blood cells
    pump
    arteries
  • The relaxation of the heart is called:
    pump
    systole
    diastole
    red blood cells
  • Blood that is high in oxygen enters the left atrium via the
    pulmonary artery
    pulmonary circuit
    pulmonary veins
    right ventricle
  • They continuously filter the blood. They retain waste products and water from the urine.
    The kidneys
    The bladder
    The Urethra
    The Ureters
  • These protect the body from germs and disease
    white blood cells
    red blood cells
    blood
    platalets
  • The contraction of the heart is called:
    systole
    pump
    red blood cells
    diastole
  • These carry blood from the heart towards all the body´s organs.
    arteries
    veins
    red blood cells
    capillaries
  • They are very small openings in our skin, which allow the sweat to leave our body.
    The kidneys
    The pores
    The ureters
    The bladder
  • What are these?
    ureters
  • It takes the blood around the rest of the body (not heart and lungs)
    the pulmonary artery
    the pulmonary circuit
    the systemic circuit
    the right atrium and the right ventricle
  • Carbon dioxide is eliminated through respiration in the
    left ventricle
    right atrium
    lungs
    waste products
  • This takes place in the air sacs in the lungs: blood releases carbon dioxide and obtains oxygen
    gas exchange
    the pulmonary artery
    right ventricle
    the pulmonary circuit
  • Blood that is high on carbon dioxide leaves through the
    gas exchange
    right ventricle
    the pulmonary artery
    the pulmonary circuit
  • They produce sweat
    The sweat glands
    The excretory system
    the waste products
    the lungs
  • We should drink ___ liters of water a day
    1.5
  • These are fragments of old cells. They help to stop bleeding from wounds.
    white blood cells
    blood
    red blood cells
    platalets
  • They are two channels that carry urine from the kidneys to the bladder.
    The kidneys
    The bladder
    The Urethra
    The ureters
  • A clear fluid liquid that transports nutrients and waste around the body.
    plasma
    blood
    red blood cells
    white blood cells
  • It takes the blood around the heart and the lungs
    the right atrium and the right ventricle
    the systemic circuit
    the pulmonary artery
    the pulmonary circuit
  • After the blood reaches the vena cava, it then enters the heart through the
    systemic circulation
    right atrium
    left ventricle
    right atrium
  • It produces and expels urine
    the left ventricle
    the excretory system
    the lungs
    the waste products
  • What are these?
    kidneys
  • It is the organ where urine is stored.
    The bladder
    The kidneys
    The ureters
    The Urethra
  • It contracts, pushing blood that is high in oxygen out of the heart, via the aorta.
    the right atrium
    the systemic circulation
    the left ventricle
    the aorta
  • These carry blood back to the heart from all the body´s organs.
    veins
    capillaries
    arteries
    red blood cells
  • Blood that is high on carbon dioxide enters the
    the pulmonary artery
    right atrium
    the pulmonary circuit
    right ventricle
  • The blood reaches all the body´s arteries from the
    left ventricle
    aorta
    systemic circulation
    right atrium
  • Blood releases oxygen and nutrients to the cells and obtains carbon dioxide.
    In the capillaries
    In the left ventricle
    In the right atrium
    In the systemic circulation
  • Gas exchange takes place in the
    the pulmonary artery
    air sacs
    right ventricle
    the pulmonary circuit
  • These carry oxygen from the lungs to all the body´s cells.
    blood
    white blood cells
    platalets
    red blood cells
  • To look after our circulatory system we should:
    Exercise regularly and eat a healthy diet
  • There are two chambers on the right of the heart:
    the left atrium and the left ventricle
    the right atrium and the right ventricle
  • Urine leaves the body through the
    The bladder

    The urethra
  • Blood that is high in oxygen enters the
    left atrium
    right ventricle
