OLIVIA GRACE STUDY NOTES

The HESI A2 entrance exam is a critical step on your journey into nursing or healthcare, and the anatomy & physiology section can be a real trip if you’re not up to speed on organ functions. It’s not just about knowing where the organs are; you need to understand what they do and why they matter. In this guide, I’ll break down key organ functions you need to know for the HESI A2 anatomy section, with examples and tips to help you ace this part of the test. Toward the end, I’ll also recommend a solid study guide and a free practice test to make sure you’re on point. Ready to dive in? Let’s do this.

What Does the HESI A2 Anatomy Section Test?

The HESI A2 anatomy & physiology section assesses your understanding of the human body’s structure and function. This includes knowing what the organs are and what they do. Here’s the breakdown:

• Number of Questions: The anatomy section typically has about 25 questions, though this can vary depending on your test setup. So you’d better know your stuff.

Organ Functions to Know for the HESI A2 Anatomy Section

Let’s talk about the organ functions you need to understand to ace the HESI A2 anatomy section. If you’re not familiar with these, you’re going to be in for a world of hurt. Here’s what you should focus on:

Heart

The heart is the engine that keeps the cardiovascular system running. You need to know its basic structure—four chambers (left and right atria, left and right ventricles), valves, and major blood vessels. Understand that the heart pumps blood through the body, delivering oxygen and nutrients to tissues and removing waste products. If you’re asked about the cardiac cycle, make sure you know about systole (contraction) and diastole (relaxation).

Lungs

The lungs are part of the respiratory system, responsible for gas exchange. They take in oxygen and expel carbon dioxide. Know the major structures like the bronchi, bronchioles, and alveoli, where gas exchange happens. If the question is about lung capacity, make sure you understand terms like tidal volume and vital capacity.

Liver

The liver is a multitasking organ in the digestive system. It produces bile, which helps digest fats, and it detoxifies harmful substances. The liver also plays a role in storing nutrients and regulating metabolism. If you’re asked about liver functions, remember that it processes nutrients from the blood and is involved in protein synthesis.

Kidneys

The kidneys are part of the urinary system, responsible for filtering waste from the blood and producing urine. You need to know about nephrons, the functional units of the kidneys, and how they filter blood to create urine. The kidneys also play a role in regulating blood pressure and electrolyte balance.

Stomach

The stomach is a muscular organ in the digestive system that breaks down food using gastric juices. It has different regions, like the fundus, body, and pylorus, each with specific roles. If you’re asked about stomach functions, remember that it mixes food with digestive enzymes and helps with the initial breakdown of proteins.

Brain

The brain is the control center of the nervous system. You need to know the major parts like the cerebrum, cerebellum, and brainstem, and their functions. The cerebrum is responsible for higher cognitive functions, the cerebellum for coordination, and the brainstem for basic life functions like breathing and heart rate.

Tips for Acing the HESI A2 Anatomy Section on Organ Functions

Now that you know the key organ functions, let’s talk about how to nail this part of the HESI A2 exam. Here are some tips to help you out:

Review the Major Organs and Their Functions

Start by reviewing the major organs and their functions. If you don’t know what the kidneys do or how the liver works, you’re going to have a tough time. Our HESI A2 anatomy & physiology study guide covers all the key organs in detail and provides clear explanations.

Practice with Sample Questions

The best way to get good at anatomy & physiology is to practice with sample questions. This helps you understand how these topics are tested on the HESI A2 exam and gives you a chance to identify weak spots. Try our free HESI A2 anatomy & physiology practice test to see where you stand.

Use Visual Aids

Anatomy & physiology can be complex, so use visual aids to help you understand the organs. Diagrams, charts, and models can make it easier to grasp the big picture. If you’re a visual learner, these tools can be a game-changer.

Stay Calm and Manage Your Time

With 25 questions in 25 minutes, time management is crucial. Keep an eye on the clock and don’t get stuck on a single question. If you’re unsure, make an educated guess and move on. And remember, you can’t skip questions and come back later, so answer each one and keep the momentum going.

Get the Right Study Tools

If you’re looking for a comprehensive resource to help you prepare for the HESI A2 anatomy & physiology section, our study guide has you covered. It provides detailed explanations of organ functions and plenty of practice questions to help you build confidence.

With these tips and the right preparation, you’ll be ready to ace the HESI A2 anatomy & physiology section. Grab our study guide, take the free practice test, and let’s get you ready to crush this exam. Good luck!
