Lesson Worksheet: Cardiovascular Disease Biology
In this worksheet, we will practice recalling the risk factors for cardiovascular disease, and evaluating the treatments.
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.
Which of the following would not be an example of a treatment for cardiovascular disease?
- BHeart bypass
- DRegular exercise
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 indicate?
- BHigh cholesterol
- CStandard weight
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: .
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.
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.
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.
Which organ is mainly affected by cardiovascular disease?
- AThe lungs
- BThe heart
- CThe brain
- DThe liver
- EThe stomach
Which of the following is not a risk factor for cardiovascular disease?
- BRegular exercise
- CA diet high in fatty foods
- ELack of exercise
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.
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.
