In medical terminology, prefixes are often used to modify the meaning of a root word, indicating quantity, position, or other characteristics. The prefix 'brady-' specifically means slow or decreased. For example, 'bradycardia' refers to a slow heart rate, and 'bradypnea' indicates slow breathing.
Question 2: Which of the following terms refers to inflammation of the liver?
- Nephritis

- Dermatitis
- Arthritis
Correct answer: Hepatitis
Medical terms are frequently constructed from root words and suffixes. The root 'hepat-' refers to the liver, and the suffix '-itis' denotes inflammation. Therefore, 'hepatitis' literally means inflammation of the liver, a condition that can be caused by various factors, including viral infections or toxins.
Question 3: Which body system is primarily responsible for transporting oxygen and nutrients?
- Respiratory System
- Digestive System
- Circulatory System (Correct answer)
- Nervous System
Correct answer: Circulatory System
The circulatory system, also known as the cardiovascular system, is primarily responsible for the vital transport of substances throughout the body. It pumps blood, which carries oxygen from the lungs and nutrients from the digestive system to all cells and tissues. Simultaneously, it transports waste products, such as carbon dioxide, away from the cells for excretion.
Question 4: Which medical root word refers to the stomach?
- Hepato
- Gastro (Correct answer)

Correct answer: Gastro
Understanding medical root words is fundamental to deciphering medical terminology. The root word 'gastro-' is derived from the Greek word for stomach. It is commonly found in terms related to the stomach and digestive system, such as 'gastritis' (inflammation of the stomach) or 'gastroscopy' (visual examination of the stomach).
Question 5: What is the largest organ in the human body?
- Liver
- Skin (Correct answer)
- Heart
- Brain
Correct answer: Skin
The skin is indeed the largest organ of the human body, both in terms of surface area and weight. It forms a protective barrier against the external environment, regulates body temperature, senses touch and pain, and plays a role in vitamin D synthesis. Its extensive coverage and multiple functions make it a vital organ.
