Science Test Respiration and Heart Flashcards
Define non-communicable disease
Disease which cannot be transmitted between organisms
State an example of a non-communicable disease
Cancer
State how to calculate cardiac output
heart rate (bpm) x stroke volume (cm2)
State the 4 components of blood
RBC, WBC, Platelets, Plasma
State 2 type of chamber in the heart
Atrium, Ventricle
State what separates chambers and state their function
Valves - prevent backflow of the blood
State the 4 blood vessels connected to the heart
Vena Cava, pulmonary artery, pulmonary vein, aorta
State a cause of cardiovascular disease
Poor diet
State the difference between breathing and respiration
Breathing is a muscular contraction
Respiration is a chemical reaction
State the word equation for aerobic respiration
Oxygen + Glucose > Carbon Dioxide + Water + Energy
State the balanced chemical equation for aerobic respiration
6O2 + C6H12O6 > 6CO2 + 6H2O + Energy
State the word equation for anaerobic respiration
Glucose > Lactic Acid + (little) energy
State which form of respiration is the best for a marathon and explain why
Aerobic - releases lots of energy slowly
State the equipment used to measure rate of respiration
Respirometer
Explain what causes a heart attack
Not enough respiration in the heart
Explain why heart rate increases during exercise
Provide cells with more oxygen and glucose for respiration and release of energy.
Explain why those suffering from arthritis do not need to be quarantined.
It is non-communicable
State a link between obesity and cardiovascular disease
Build up of fatty plaques/cholesterol in arteries increasing risk of CVD
Explain the term “double-circulatory system”
Left side of the heart pumps oxygenated blood around the body, right side of the heart pumps deoxygenated blood to the lungs.
State the definition of disease
Disorder of structure or function of an organism
