The Heart and respiration Flashcards
what is the function of the heart
pumps blood around the body
what are the 8 structures in the heart
pulmonary artery
aorta
vena cava
pulmonary vein
right atrium
left atrium
right ventricle
left ventricle
what is the purpose of the pulmonary artery
carries deoxygenated blood from heart to lungs
what is the purpose of the vena cava
brings deoxygenated blood from the body to the heart
what is the purpose of the aorta?
carries oxygenated blood from heart to body
what is the purpose of the pulmonary vein
brins oxygenated blood from the lungs to the heart
what is the purpose of valves in the heart
prevents blood backflow
which side of the heart deals with oxygenated blood
LEFT
give a timeline of how blood is pumped around the body
blood enters the right atrium
the atria contract, forcing blood into the ventricle
the ventricles contract forcing blood into the arteries
blood flows to organs and returns to the heart
what is the formula for respiration
glucose + oxygen –> carbon dioxide + water
where does aerobic respiration occur
in the mitochondria
what type of reaction is aerobic respiration
exothermic
give 3 reasons that aerobic respiration is used in animals
for metabolic processes to build larger molecules such as proteins
to enable muscle contractions
to maintain body temperature
give 1 reason that aerobic respiration is used in animals
to build larger molecules such as sugars and nitrates
why is anaerobic respiration used
when there is not enough oxygen for aerobic respiration
