Lesson Worksheet: Cardiovascular Disease Biology

In this worksheet, we will practice recalling the risk factors for cardiovascular disease, and evaluating the treatments.

Q1:

Body mass index (BMI) compares the height and weight of an adult to predict the proportion of fat in their body. Why is BMI not a good predictor of body fat for professional weight lifters?

  • AProfessional weight lifters are often shorter than the average person.
  • BBMI does not differentiate between body fat and body muscle.
  • CProfessional weight lifters are often heavy.
  • DBMI is not scientifically recognized.

Q2:

Which of the following would not be an example of a treatment for cardiovascular disease?

  • AStatins
  • BHeart bypass
  • CAntibiotics
  • DRegular exercise
  • EStents

Q3:

Body mass index compares the height and weight of an adult to predict the proportion of fat in their body. What does a BMI of >30/kgm indicate?

  • AMalnutrition
  • BHigh cholesterol
  • CStandard weight
  • DObesity
  • EUnderweight

Q4:

Body mass index (BMI) compares the height and weight of an adult to predict the proportion of fat in their body.

The equation is as follows: BMIkgmbodymasskgheightm/=()÷().

Calculate the BMI of a man who is 1.70 m tall and has a mass of 70 kg to one decimal place.

Calculate the BMI of a woman who has a mass of 59 kg and is 1.65 m tall to one decimal place.

Q5:

Which of the following best explains how statins work?

  • AThey are mesh tubes that widen arteries and allow better blood flow.
  • BThey replace damaged blood vessels with artificial ones.
  • CThey reduce blood cholesterol to prevent fatty deposits forming in blood vessels.
  • DThey reduce high blood pressure to lessen the risk of a heart attack.

Q6:

Which of the following best describes obesity?

  • ALarge amounts of fat form under the skin and organs.
  • BThere is more muscle on the body than fat.
  • CFat is deposited on the hips.
  • DSmall amounts of fat collect around the organs.
  • EThe mass of someone is above 60 kg.

Q7:

Which organ is mainly affected by cardiovascular disease?

  • AThe lungs
  • BThe heart
  • CThe brain
  • DThe liver
  • EThe stomach

Q8:

Which of the following is not a risk factor for cardiovascular disease?

  • ASmoking
  • BRegular exercise
  • CA diet high in fatty foods
  • DObesity
  • ELack of exercise

Q9:

Eating too much food that is high in saturated fat and cholesterol can increase a person’s risk of developing cardiovascular disease. Why?

  • ASaturated fat and cholesterol increase heart rate, which can tire the heart more quickly.
  • BFat deposited in the arteries can clog them, preventing the flow of blood.
  • CCholesterol reduces the oxygen-carrying capacity in the blood.
  • DCholesterol is a carcinogen and can increase the risk of mutations in the cells of the heart.
  • ESaturated fat damages the platelets in the blood leading to problems with blood clotting.

Q10:

How can a buildup of fat in the blood cause a heart attack?

  • AFat widens the blood vessels and allows a higher volume of blood to pass through.
  • BMore fat in the blood decreases blood pressure, which leads to heart failure.
  • CMore fat increases the number of platelets in the blood, so blood clots more easily.
  • DFat blocks blood vessels and prevents oxygen from reaching the heart.
  • EFat interacts with hemoglobin and reduces the blood’s oxygen-carrying capacity.
