Final answer:
Cardiology can be divided into 'cardio-' meaning heart and '-logy' meaning the study of. Cardiologists specialize in heart health. The term's roots trace back to Latin, helping to understand terminology like 'interatrial septum'.
Step-by-step explanation:
To divide the term cardiology into parts, we break it down as follows: 'cardio' refers to the heart, stemming from the Latin term kardia, and '-logy' is a suffix that means 'the study of.' Cardiology is thus the study of the heart, and cardiologists are physicians specializing in heart health. Breaking down medical terms can help decipher their meanings; for instance, 'interatrial septum' involves 'inter-' meaning 'between,' 'atrial' referring to the atria of the heart, and 'septum' meaning a dividing wall or partition.
