Maybe fibrinogen, prothrombin, and the lipoproteins?

I would think so too... At my states tehy asked about what controls the pH of the blood, and I believe the answer was bicarbonate.

yup that was it....that's wat that guy said

Can anyone explain what automated pacemakers and defibrillators do? And what is the role of aspirin in heart attacks?

well pacemakers and defibrillators would regulate the beating of the heart
i'm not sure of aspirin in heart attacks though

asprin thins the blood and this puts less tress on the blood

Artificial Pacemakers are used to simulate the "pacemaker" tissue of the SA node. It helps allow the heart (atria) contract correctly. Defibrillators provide an electrical shock to get the heart back into normal rhythm. Aspirin is used to thin the blood and prevent heart attacks/ strokes

Do artificial pacemakers make the ventricles contract?

Well, the pacemaker is what directly allows the atria to contract, but then the electrical impulse goes down to the AV node, and then passes to the Bundle of His, into the bundle branches, and then goes to the purkinje fibers, which makes the ventricles contract. So yes, it does technically make the ventricles contract.

Can we talk about the muscular system now? that and the skeletal system is going to be the topic for anatomy for next year. (it's on soinc)
