Cardiovascular System: Heart

Delay in impulse conduction occurs at:

Go with B — AV node. Within Cardiovascular System: Heart, that statement lines up with the standard definition and the usual exam wording you’ll see. In plain terms, AV node is the option that correctly names the structure, process, or principle asked for in Cardiovascular System: Heart. Holding that picture in mind makes AV node feel natural rather than something you only memorise. Link the term to a real body example (organ, tissue, or ion flow) so the idea stays concrete under exam pressure. A short mental diagram helps — start from stimulus or structure, follow the pathway, and stop at the functional result described by AV node.

Cardiovascular System: Heart

The pacemaker of heart is:

Answer: C) SA node. For Cardiovascular System: Heart, once you lock onto the key mechanism or definition, SA node is the clear fit. If you restate the concept in your own words, SA node is the option that correctly names the structure, process, or principle asked for in Cardiovascular System: Heart. So SA node is the clean, accurate selection. If a similar stem appears later, start from the same core fact and you will land on the same kind of answer. In class notes, highlight this same phrase next to the related diagram so the wording and the picture reinforce each other.
