The ATI TEAS Version 7 Science Practice Test 2026/2027 is an 8-page exam-preparation resource containing 40+ practice questions and answers covering major science concepts relevant to TEAS preparation. The material combines human anatomy and physiology, biology, genetics, chemistry, cell biology, and scientific reasoning, giving students a focused question-and-answer review of frequently tested scientific principles.
The human anatomy and physiology questions address blood groups and circulation, oxygenation, intracellular signaling, digestion and nutrient absorption, skeletal muscle, nervous-system responses, connective tissue, homeostasis, reproduction, respiratory anatomy, hematopoiesis, and urinary-system function. The document also reviews the digestive pathway from the oral cavity through the pharynx, esophagus, stomach region, small intestine, large intestine, and colon, alongside kidney functions involving water balance, electrolyte regulation, and metabolic-waste elimination.
The biology and genetics portion examines cell theory, biological organization, plant-cell structures, autotrophs, nucleotides, the G1, S, G2 and M stages of the cell cycle, chromosomes, Mendelian genetics, heredity, phenotype, alleles, and the relationship between amino-acid sequences and protein structure. Questions also reinforce scientific reasoning through experimental controls, correlation, inductive reasoning, research observations, and applications of the scientific method.
The chemistry and physical science content reviews acids and bases, pH, neutralization reactions, covalent bonding, cations, protons, neutrons and electrons, isotopes, homogeneous and unsaturated solutions, single-replacement reactions, evaporation, vaporization, states of matter, intermolecular forces, and particle cohesion. Together, these sections provide concentrated practice across several science disciplines rather than limiting preparation to anatomy alone.
Academic and Exam Relevance
This document is especially relevant for pre-nursing and allied-health students preparing for the ATI TEAS 7 Science section, including applicants to registered nursing, practical nursing, vocational nursing and other health-science programs that use TEAS performance during admissions. It can also support students who need additional practice with anatomy and physiology, general biology, genetics, chemistry, and scientific reasoning before taking a nursing-school entrance examination.
The subject coverage is consistent with the broad science domains associated with the ATI TEAS Version 7, particularly human anatomy and physiology, biology, chemistry, and scientific reasoning. Students can use the document for targeted revision, question-and-answer practice, concept recall, and identification of science topics that may require further study.
Relevant students: ATI TEAS 7 candidates, pre-nursing students, nursing school applicants, ADN applicants, BSN applicants, PN students, LPN/LVN program applicants, allied-health applicants, pre-health students, and students reviewing anatomy and physiology, biology, chemistry, genetics, cell biology, and scientific reasoning.
Recommended academic reference: OpenStax, Anatomy and Physiology 2e, which provides foundational coverage of human body organization and major physiological systems relevant to many of the anatomy and physiology concepts represented in the document.
Exam reference: ATI Testing, ATI TEAS Study Manual 2024–2025, a dedicated ATI resource for reviewing the Reading, Mathematics, Science, and English and Language Usage content assessed by the TEAS.
