HESI A2 Anatomy and Physiology practice test
Body systems, structures, and what each one is for.
The HESI A2 has no fixed length. Elsevier publishes eight academic components and each nursing program picks which ones its applicants sit, so the question count and time limit for this component depend on your program — here is what to ask them.
Which is the correct order of the small intestine’s segments?
What this section asks
The component most programs add on top of the core four, and the one most worth the study hours, because it is also half of the TEAS science section. Systems, the major structures inside each, directional and positional terms, and the basic physiology that connects them.
Frequently asked
- How many questions are in the HESI A2 Anatomy and Physiology component?
