Dr Matt & Dr Mike's A-Z of the Human Body is a concise, engaging podcast series that explores human anatomy and physiology one term at a time. Hosted by Dr Matt Barton (Griffith University) and Dr Mike Todorovic (Bond University), both experienced educators and science communicators, the series aims to make complex medical concepts accessible and enjoyable.
The action is to start with the target, not the drug name. This refresher is worth opening before the next fever, sore throat, cough, dysuria or red swollen skin lesion, because it rebuilds Gram status, cell wall logic and resistance from first principles.
Do not file persistent abdominal pain or vomiting on GLP-1 therapy under expected side effects. The teaching point is action: screen early for pancreatitis, gallstones, or delayed gastric emptying, and flag peri-operative aspiration risk before standard fasting falsely reassures the team.
Delayed onset muscle soreness reflects eccentric microdamage and inflammation rather than lactic acid. Clinically, timing matters: soreness peaking after one to three days fits DOMS, whereas marked weakness, fever, focal swelling or urine change after exertion should trigger assessment for alternative pathology.
Morphine review starts with one bedside rule: increasing opioid requirements are a reason to reassess, not just prescribe more. Check respiratory drive, sedation and pinpoint pupils, think about tolerance, dependence or opioid-induced hyperalgesia, and remember naloxone reversal still needs ongoing monitoring.
Frame new oedema through hydrostatic pressure, oncotic pressure and lymphatic drainage before reaching for diuretics. Capillary structure and glycocalyx injury help explain why heart failure, nephrotic syndrome and chronic liver disease produce different patterns of swelling and ascites.
Symptom pattern matters in everyday gastroenterology: ulcer-pattern dyspepsia should trigger Helicobacter pylori testing, recurrent reflux usually needs proton pump inhibition rather than repeated antacids, and right upper quadrant pain after fatty meals should move biliary colic up the differential.
