HESI A2 Anatomy and Physiology Review
The Anatomy and Physiology test is one of the main components of the HESI A2. Because these subjects are so foundational when it comes to understanding the human body and human health, they’re very important to a nursing education, and most nursing schools require their applicants to take this part of the HESI. There are 30 questions on this part of the HESI exam, and the recommended time limit is 25 minutes. Colleges and universities don’t have to adhere to the recommended time limit, but most do. Like every other section of the HESI A2, there are five moot questions on this test. They’re moot because they will have no effect on your score. That’s because Elsevier, the test developer, is trying them out to see if they’ll be added to future versions of the exam. It would be nice if you knew which questions counted and which don’t, but that would defeat the whole purpose of putting them on the exam, so you should treat every question as if it counts.
What’s on the HESI A2 Anatomy and Physiology Test?
The study of the different parts of the body, what they do, and where they’re located, constitutes anatomy. Think of it as a kind of geography of the human body. Physiology is the study of how all the different organs, muscles, bones, and every other part of the human anatomy work together to sustain life and health. These are wide ranging and deep subjects, and there’s no way a test with only 30 questions can come close to covering everything you’ll need to know, but you’ll still need to prep and review for this exam thoroughly. While there are only a few questions, relatively speaking, they can be about any subject in physiology or anatomy, so you’ll need to be very knowledgeable to do well on this HESI A2 Anatomy and Physiology Test. To become more familiar with these types of questions, we offer free HESI A2 Anatomy and Physiology practice questions.
Here are some topics you should be very familiar with before taking the exam:
Major organs – you can probably locate the brain and the heart on a drawing of the human body, but you should also be able to do the same with the liver, the kidneys, the bladder, the stomach, the lungs, the large and small intestines, etc.
Cells and tissues – these are the basic building blocks of the human body, and you’ll need to know the main parts of a cell, what they do, the four main types of tissues, and the characteristics and functions of each type, etc.
Skeletal system – it’s important to know how many bones the human body has, how they work with the other systems of the body, such as muscle and nerves, the names and locations of different bones, what bones are made of, common injuries and illnesses that affect the skeletal system, etc.
Muscular system – you’ll need to be able to identify and name the major muscles of the human body, and describe their functions, the two types of muscle fibers and their characteristics, and common injuries and illnesses that affect the muscular system, etc.
Integumentary system – you’ll need to understand the different parts of the skin and their various functions, and common injuries and illnesses that affect the skin, etc.
Nervous system – you’ll need a solid understanding of the functions and components of the body’s central nervous system, the peripheral nervous system, what neurons are and what they do, spinal nerves and cranial nerves, ganglia, the functions of and differences between the voluntary and involuntary nervous systems, neuroglial cells, and common injuries and illnesses that affect the nervous system, etc.
Reproductive system – you’ll want to know the names and functions of the different parts of both male and female reproductive systems, what happens in puberty, differences between adult males and adult females, what testosterone and estrogen are and what they do, the ovarian and menstrual cycles, and common injuries and illnesses that affect the reproductive system, etc.
Respiratory system – important items include: the organs and structure of the respiratory system, the functions of each part and how the whole system works together, Boyle’s law, inspiration and expiration, the respiratory membrane, how blood carries oxygen throughout the body, and common injuries and illnesses that affect the respiratory system, etc.
Cardiovascular system – important items include: the organs and structure of the cardiovascular system, the functions of each part and how the whole system works together, the various parts of the heart and lungs and what each does, the three layers of blood vessels, heart rate and pulse, the path of blood through the heart and through the entire body, veins, arteries, capillaries, and common injuries and illnesses that affect the cardiovascular, etc.
Endocrine system – you’ll need to know what the endocrine system is and what it does, the organs of the endocrine system, hormones and hormone receptors, the structure and functions of the pituitary gland and the hypothalamus and how they work together, the major hormones and what they do, and common injuries and illnesses that affect the endocrine, etc.
Digestive system – important items include: saliva and digestive fluids and how they break down foods, the structure and function of the major organs of the system including the stomach, the esophagus, the livers, the gall bladder, the large and small intestines, and the pancreas, and common injuries and illnesses that affect the digestive system, etc.
Renal system – you’ll need to understand the critical role the kidneys play in human health, how urine is formed, acidity and alkalinity, how the kidneys filter the blood, the path of blood to and from the kidneys, and common injuries and illnesses that affect the renal system, etc.
Frankly, that’s a lot of material to cover when you’re reviewing for the HESI A2 Anatomy and Physiology exam. It’s vital to start prepping for the HESI well before you take the test, and to use a systematic and thorough review system.
