ATI TEAS 7 Science Practice Test and Review
The science section of the ATI TEAS is arguably the most difficult section. There’s probably not a person out there who has taken the TEAS that will tell you that science wasn’t the hardest most in-depth area.Â
For this reason we’re going to do a deep dive into all the topics you might see on the test. We’ll go over all the topics but also some of the more anecdotal things like tips, strategies and the types of questions that you might see.
The science section of the TEASÂ is going to have 50 questions in 60 minutes.Â
The test does have unscored questions, for this section 44 questions are scored and 6 questions are unscored, but you won’t know which ones.Â
A&P is by far the area you need to know the most about, and roughly 18 of the 50 questions will be on A&P.Â
So this is your high value topic that you should be spending the most time studying.
The Smart Edition Academy online course covers every topic covered on this page in a very detailed way so that you can really learn and understand each topic, and you have the option to learn it with lesson modules, video lessons, test banks, flashcards, and practice tests.
A&P Organization of systems: TEAS Science Practice Test
Organization of the the human body​
The 7 levels are:Â
- chemicalÂ
- organelles
- cellÂ
- tissueÂ
- organ
- organ system
- organism
Make sure you know the body cavity and the terminology, a few or them to know are:
- Posterior
- anterior
- lateralÂ
- distal
- medial
Know the body planes:Â Â Â
- upper limbsÂ
- lower limbs
- central region
- head region
The four types of human tissue:
- connectiveÂ
- epithelialÂ
- muscleÂ
- neural
Know homeostasis and feedback mechanisms and understand the differences between them:
- negative feedback
- positive feedback
Organization of the the human body​
You will see lots of questions on the cardiovascular system on the TEAS.Â
You need to know the flow of the heart like the back of your hand. You will likely have 3-4 questions on the cardiovascular system.
One great tip that can help you is to draw or label diagrams of the heart with your book or online course closed, if you can do this then that’s how you know that you’re really starting to understand how these systems work.Â
In the Smart Edition Academy online course, we have a lot of diagrams and illustrations that go into detail on this topic with interactive questions.
An example would be where you have to drag and drop the labeling of the heart or an EKG chart which really helps you to know this system by working with interactive questions and activities like this.
You need to know the functions of blood in homeostasis as well as the blood groupings:
- A
- B
- AB
- O
You should work towards having a solid understanding of cardiovascular anatomy which include things like:
- Atria
- Ventricles Â
- SeptumÂ
- The three layers of the heart wall
- The four valves that regulate blood flow in and outÂ
The four heart valves are:
- Aortic
- Mitral
- Tricuspid
- Pulmonary

Respiratory System
This lesson in the Smart Edition TEAS course introduces the anatomy of the respiratory system and how each organ within this system functions.Â
It also discusses the mechanics of breathing and respiration.
As with all systems you’ll need to know the anatomy of the respiratory system which includes things like:
- upper and lower tracksÂ
- nasal cavity
- larynxÂ
- pharynxÂ
- trachea
Amongst other things to be familiar with the respiratory functions and the breathing mechanics.
Gastrointestinal System
This lesson introduces the structures and functions of the digestive system.Â
You’ll need to know the anatomy of the digestive system as well knowing the path of food into the system.
Digestion is a big part of this system so you will be expected to know how digestion works.Â
There are some accessory organs to the gastrointestinal system to like:
- liverÂ
- pancreas
- gallbladderÂ
- tongue
In addition to the above you’ll want to know disorders of the digestive system:
- Stomach:Â vomiting and ulcers
- Liver:Â cirrhosis and hepatitisÂ
- Intestines: IBS (irritable bowel syndrome), Crohn’s disease, colitis, and appendicitis
