Choice A rationale: While ‘A’ is a vowel, it is not the most commonly used vowel when combining word parts in medical terminology.

Choice B rationale: ‘E’ is also a vowel, but it is not the most commonly used vowel when combining word parts in medical terminology.

Choice C rationale: ‘I’ is occasionally used as a combining vowel in medical terminology, but it is not the most commonly used.

Choice D rationale: ‘O’ is the most commonly used vowel when combining word parts in medical terminology. It helps with pronunciation and is placed to connect two word roots or to connect a word root and a suffix.

Choice E rationale: ‘U’ is a vowel, but it is not the most commonly used vowel when combining word parts in medical terminology

Choice A rationale:

A suffix is a word part that is added to the end of a root word to modify its meaning. For example, in the medical term "cardiologist," the suffix '-ologist' means a specialist or expert. A suffix is placed at the end of a root word or a combining form to create a specific medical term.

Choice B rationale:

A word root is the foundational part of a medical term. It contains the core meaning of the term and is not usually modified by prefixes or suffixes. For instance, in the term "cardiology," 'cardi-' is the word root, representing the heart. Word roots provide the essential meaning of the medical term.

Choice C rationale:

A prefix is a word part that is added to the beginning of a root word or a combining form to modify its meaning. Prefixes are important in medical terminology as they indicate locations, numbers, or time. For example, in the term "prehypertension," the prefix 'pre-' means before. Prefixes are added at the beginning of a word.

Choice D rationale:

A combining form is a word root combined with a vowel (usually 'o') that can be joined with other word parts to create a medical term. Combining forms are used as a connector to join a root word and a suffix or another root word. For example, in the term "gastritis," 'gastr-' is the combining form, representing the stomach. Combining forms facilitate the construction of complex medical terms.
