CABT Anatomy, Physiology & Medical Terminology — Questions and Answers
Question 1: What organ is responsible for pumping blood throughout the body?
- Liver
- Lung
- Heart (Correct answer)
- Kidney
Correct answer: Heart
The heart is the central organ of the circulatory system, responsible for pumping blood throughout the entire body. It circulates oxygen-rich blood to tissues and organs, and returns deoxygenated blood to the lungs. This continuous pumping action is vital for delivering nutrients and removing waste products, sustaining life.
Question 2: Which body system is primarily involved in oxygen exchange?
- Digestive system
- Nervous system
- Respiratory system (Correct answer)
- Skeletal system
Correct answer: Respiratory system
The respiratory system is primarily responsible for the exchange of gases, specifically taking in oxygen and expelling carbon dioxide. This vital process occurs mainly in the lungs, where oxygen from inhaled air diffuses into the bloodstream and carbon dioxide from the blood diffuses into the air to be exhaled. It is essential for cellular respiration and maintaining the body's pH balance.
Question 3: What does the term 'anterior' refer to in anatomy?
- Back
- Top
- Front (Correct answer)
- Side
Correct answer: Front
In anatomical terminology, 'anterior' refers to the front of the body or a body part. It is used to describe the position of structures relative to others. For example, the sternum (breastbone) is anterior to the spine.
Question 4: Which type of tissue connects muscles to bones?
- Ligaments
- Cartilage
- Tendons (Correct answer)
- Fat
Correct answer: Tendons
Tendons are strong, fibrous connective tissues that attach muscles to bones. They are crucial for transmitting the force generated by muscle contractions to the bones, enabling movement. Ligaments, in contrast, connect bones to other bones, providing joint stability.
Question 5: What is the medical term for high blood pressure?
- Hypotension
- Hyperglycemia
- Hypertension (Correct answer)
- Hypoglycemia
Correct answer: Hypertension
Hypertension is the medical term for high blood pressure, a condition where the force of blood against the artery walls is consistently too high. It is a significant risk factor for heart disease, stroke, and kidney disease. Regular monitoring and management are crucial for individuals diagnosed with hypertension.
Question 6: What does the prefix 'brady-' mean in medical terminology?
- Fast
- Low
- Slow (Correct answer)
- High
Correct answer: Slow
The prefix 'brady-' in medical terminology means slow. It is commonly used in terms like 'bradycardia' (slow heart rate) or 'bradypnea' (slow breathing). Understanding such prefixes is fundamental for interpreting medical terms.
Question 7: Which part of the brain controls balance and coordination?
- Cerebrum
- Brainstem
- Cerebellum (Correct answer)
- Thalamus
Correct answer: Cerebellum
The cerebellum, located at the back of the brain below the cerebrum, plays a critical role in motor control, coordination, and balance. It helps refine movements, maintain posture, and learn new motor skills. Damage to the cerebellum can result in problems with coordination and equilibrium.
Question 8: What is the function of the kidneys?
- Pump blood
- Digest food
- Filter blood (Correct answer)
- Control breathing
Correct answer: Filter blood
The kidneys are vital organs that primarily function to filter waste products and excess water from the blood to produce urine. They also play crucial roles in regulating blood pressure, electrolyte balance, and red blood cell production. This filtration process is essential for maintaining the body's internal chemical balance.
Question 9: What does the abbreviation 'BP' stand for in medicine?
- Body Pulse
- Blood Profile
- Blood Pressure (Correct answer)
- Brain Potential
Correct answer: Blood Pressure
In medicine, 'BP' is a widely recognized abbreviation for Blood Pressure. It refers to the force exerted by circulating blood against the walls of the body's arteries. Monitoring BP is a routine part of medical examinations and is crucial for diagnosing and managing conditions like hypertension or hypotension.
