The human body is classified broadly based on the region of location or its function. Medical terminology is basically used to understand the problem in the region, the study and functioning and also the connection between them.

A medical term is made up of a root, prefix and suffix. By breaking them down individually you can easily tell what the term means.

A prefix typically consists of a few letters and comes before the word. In the word cardiology the prefix is cardio. So, any problem related to the heart or its functioning is referred to with the prefix cardio. Cardiology means the study of the heart. So, any term relating to cardiology like cardiovascular, cardiogram all refer to the condition of the heart.  

A suffix tells or explains the condition the main word or the root is referring to. For example, in the term cardiology the suffix is "ogy". It usually refers to a study or related to a particular organ of the body. There are several such suffixes used to describe a condition or a study or an illness.  The suffixes are not specific to cardiology or any other part of the  body and they can be used in combination with any word depending on the meaning to specify.
