Human Anatomy and Physiology
This topic covers body systems, homeostasis, tissues, organs, cardiovascular, respiratory, digestive, endocrine, nervous, immune, reproductive, urinary, and musculoskeletal function.
How to study for the ATI TEAS
Build every answer around evidence, units, data, anatomy and physiology, scientific reasoning, grammar rules, and efficient timed elimination.
Core concepts
Concept 1
Human Anatomy and Physiology questions test whether a TEAS candidate can apply core academic skills to nursing and allied-health readiness scenarios.
Exam cue: Identify whether the item is reading, math, science, or English and language usage.
Concept 2
The best answer usually follows the passage, data, rule, equation, scientific relationship, or grammar convention that is directly supported.
Exam cue: Find the controlling evidence: passage detail, equation, table, graph, anatomy relationship, experiment design, or sentence rule.
Concept 3
Eliminate answers that overinfer, ignore units, skip passage evidence, confuse scientific terms, or choose what sounds right without checking the rule.
Exam cue: Use process of elimination for extreme, unsupported, unit-inconsistent, or grammatically mismatched choices.
Risk pitfalls and guardrails
Choosing an answer that is true in general but not supported by the passage or data.
Guardrail: Avoid outside assumptions, unit mistakes, graph-scale misses, science term swaps, and sentences that sound polished but break grammar rules.
Losing points to unit conversion, graph scale, sign, decimal, or rounding errors.
Guardrail: Avoid outside assumptions, unit mistakes, graph-scale misses, science term swaps, and sentences that sound polished but break grammar rules.
Treating similar science or grammar terms as interchangeable.
Guardrail: Avoid outside assumptions, unit mistakes, graph-scale misses, science term swaps, and sentences that sound polished but break grammar rules.
Memory anchors
Homeostasis
Homeostasis is maintenance of stable internal conditions.
Tissue
Tissues are groups of similar cells performing related functions.
Organ
Organs are structures made of tissues working together.
Cardiovascular
The cardiovascular system transports blood, oxygen, nutrients, hormones, and waste.
Respiratory
The respiratory system exchanges oxygen and carbon dioxide.
Digestive
The digestive system breaks down food, absorbs nutrients, and eliminates waste.
Nervous
The nervous system coordinates rapid communication and control.
Endocrine
The endocrine system uses hormones for slower regulation.
Immune
The immune system defends against pathogens and abnormal cells.
Urinary
The urinary system filters blood, regulates fluid balance, and removes wastes.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
