CET Anatomy, Physiology & Medical Terminology

Question 1

Which organ is primarily examined during a colonoscopy?

Accepted Answer

Colon

Answer

A colonoscopy is a medical procedure specifically designed to visualize the entire length of the large intestine, also known as the colon. This examination helps detect abnormalities such as polyps, inflammation, or cancer, making the colon the primary organ of focus.

Question 2

What does the medical term 'esophagogastroduodenoscopy' refer to?

Accepted Answer

Upper gastrointestinal endoscopy

Answer

The term 'esophagogastroduodenoscopy' (EGD) breaks down into its anatomical components: 'esophago-' referring to the esophagus, 'gastro-' to the stomach, and 'duodeno-' to the duodenum (the first part of the small intestine). Therefore, an EGD is a procedure that visually examines these upper parts of the gastrointestinal tract.

Question 3

What is the role of the epiglottis during swallowing?

Accepted Answer

Covers the trachea to prevent aspiration

Answer

The epiglottis is a leaf-shaped flap of cartilage located at the base of the tongue. During swallowing, it folds down to cover the opening of the trachea (windpipe), effectively preventing food or liquid from entering the respiratory tract and causing aspiration into the lungs.

Question 4

Which body system includes the esophagus, stomach, and intestines?

Accepted Answer

Digestive system

Answer

The esophagus, stomach, and intestines are all integral components of the digestive system. This system is responsible for the ingestion, digestion, absorption of nutrients, and elimination of waste from the body.

Question 5

What does the prefix 'gastro-' refer to in medical terminology?

Accepted Answer

Stomach

Answer

In medical terminology, the prefix 'gastro-' consistently refers to the stomach. This is evident in terms like 'gastritis' (inflammation of the stomach) or 'gastroscopy' (visual examination of the stomach).
