<p>Hi guys,
Do I need to be familiar with the respiratory system for the ap exam? Which other body systems do I need to know about and how in depth should I look it over?</p>
<p>According to what my teacher told me, all of the body systems are taken out of the new AP Bio exam and the only chapter she teaches from animal function/form is the first chapter and the one on developmental biology which has info on asexual reproduction and stuff</p>
<p>Immune, endocrine and nervous systems. (3 cell-communication topics) Don’t just memorize the parts, but UNDERSTAND the processes, especially the steps that chemical A could lead to response X. For example, learn how a antibody attacking postsynaptic receptor leads to what responses.</p>
<p>Immune system is very important, and you need to know the endocrine and nervous systems in the context of cell communication. So understand how hormones work, the two classes of hormones (steroid/protein), an example of a response (epinephrine is the most common), how they’re regulated (negative, occasionally positive, feedback), etc. For nervous system, how neurons and action potentials work, what a neurotransmitter is, how neurons can bring about responses in other cells (like muscle cells), etc. </p>
<p>As for the others - probably not. However, I don’t think it could hurt to familiarize yourself briefly with the major processes in each system (circulatory: path of blood; respiratory: gas exchange; muscular: muscle contraction; etc.) because they could help on an essay or appear as a choice on an MC question.</p>
