Lesson Worksheet: The Heart Biology
In this worksheet, we will practice describing the basic structure of the heart and explaining how the heart is adapted for its function.
Q1:
Which of the following best defines the term heart rate (bpm)?
- AThe number of times the heart stops per minute
- BThe volume of blood the heart releases per second
- CThe volume of blood the heart releases per minute
- DThe number of times the heart beats per hour
- EThe number of times the heart beats per minute
Q2:
Why is the blood transported to the lungs?
- ATo absorb water
- BTo absorb carbon dioxide
- CTo become deoxygenated
- DTo become oxygenated
Q3:

- ARight ventricle
- BRight atrium
- CLeft atrium
- DLeft ventricle
Q4:
From what chamber does the oxygenated blood leave the heart to be transported around the body?
- ARight atrium
- BLeft atrium
- CRight ventricle

- BLeft atrium
- CRight ventricle
- DLeft ventricle
Q6:
Through what chamber does the deoxygenated blood from the body enter the heart?
