AL-MED is a place to study medicine from the molecule to the patient: short lessons, practice questions that explain themselves, flashcards and a notebook, with your teachers a message away.

Hemoglobin about 6 nm

Four protein chains, each holding a heme with one iron atom. Oxygen binding at one heme makes the next one bind more easily, which is why the dissociation curve is S-shaped.

A short reading and three questions from Adrenergic receptors, the way they appear in the course. No account needed.

From Autonomic Pharmacology · Adrenergic receptors

Adrenaline and noradrenaline do different things in different tissues because the receptors differ. α₁ receptors on blood vessels constrict them. β₁ receptors on the heart raise its rate and the force of each beat. β₂ receptors in the airways relax the smooth muscle and open them up.

Pick a drug, find its receptor, and you can usually predict what it will do, and what it might do that you didn't want.

  1. 1A patient's blood pressure is falling and phenylephrine is started. Which receptor does it act on to raise the pressure?

  2. 2Why can propranolol, a non-selective β-blocker, be dangerous for someone with asthma?

  3. 3In cardiogenic shock, dobutamine is chosen mainly for which effect?

  4. Answer to see why. No account needed.

How a study session goes

Most sessions follow the same four steps. Each one is a real part of AL-MED, not a promise.

  1. Read

    Short readings and video lessons, one idea at a time, in the order your module sets.

  2. Practise

    Quizzes at the end of each block, then a review of every answer you gave.

  3. Recall

    Flashcards for the facts worth carrying, and a notebook for your own summaries.

  4. Connect

    Ask a teacher, join a study group, and watch your accuracy and weekly hours on Progress.
