ADVICE

Apply The Rule Of Fives

For short-answer exams, use the rule of fives: list five points and give brief reasons for each to score higher.
Keep answers brief, structured, and easy for examiners to mark quickly.

INSIGHT

Why Blood Volume And Hypertension Rise

Increased intravascular volume in obesity arises from extra adipose tissue and neurohormonal activation, not adipocytes producing angiotensin II.
Sympathetic activation and renin–angiotensin system activation drive hypertension alongside expanded blood volume.
