Nursing ATI TEAS 7 Test – Complete
Study Notes & Answer Key
(Comprehensive Review Material)
Introduction:
This document provides a complete set of ATI TEAS 7 study
notes covering all major exam sections, including Anatomy &
Physiology, Reading, Math, Science, and English Language
Usage. It summarizes key concepts, definitions, systems,
processes, formulas, and terminology needed for the TEAS 7
exam. The material is structured with clear explanations and
answer-style definitions to support efficient studying.
It serves as a comprehensive review resource aligned with
topics commonly tested on the ATI TEAS 7 entrance exam.
Exam Questions and Answers:
Arteries -Answers:-thick-walled blood vessels that carry blood
away from the heart to deliver oxygenated blood to body
tissues
Atria -Answers:-the two upper chambers of the heart
,Lymph -Answers:-a watery, plasma-like fluid that contains
white blood cells. It flows through tissues and vessels,
eventually entering the large veins that return to the heart
Plasma -Answers:-contains nutrients, hormones, antibodies,
and other immune proteins
Platelets (thrombocytes) -Answers:-form blood clots to stop or
control bleeding
Red Blood Cells (erythrocytes) -Answers:-contain hemoglobin
and transport oxygen and carbon dioxide
Valves -Answers:-flaps of leaflets that prevent blood from
flowing backward. The four main heart valves are the tricuspid
(between right atrium and right ventricle), pulmonary
(between right ventricle and pulmonary artery), mitral
(between left atrium and left ventricle), aortic (between left
ventricle and aorta)
Veins -Answers:-blood vessels that carry deoxygenated blood
from the body back to the heart
,Ventricles -Answers:-the two lower chambers of the heart
White Blood Cells (leukocytes) -Answers:-part of the body's
immune system, the defend against infection. Divided into
granulocytes (basophils, eosinophils, neutrophils) and
agranulocytes (monocytes, lymphocytes)
Gastrointestinal/Digestive System -Answers:-breaks down
food and processes nutrients for absorption and distribution
Digestive System (main structures) -Answers:-oropharynx,
epiglottis, esophagus, stomach, duodenum, jejunum, ileum,
cecum,, vermiform appendix, colon (large intestine), rectum,
gallbladder, liver, pancreas
Mechanical Digestion -Answers:-starts at the mouth, where
food is physically broken down and mixed with saliva. The
process continues with chemical digestion: Enzymes further
break down the food, which moves through the system by
peristalsis. Water and many digested nutrients are absorbed
into the bloodstream in the small intestine. The large intestine
also absorbs water and vitamin k, and the waste products are
moved into the rectum for storage before evacuation.
, 3 Main Secretions of the Stomach -Answers:-pepsinogen (chief
cells), mucus (goblet cells), and hydrochloric acid (parietal
cells)
Duodenum -Answers:-the first part of the small intestine, uses
alkaline bile (a fluid produced in the liver and stored in the
gallbladder) to help neutralize chyme, an acidic substance
containing gastric juices and partially digested food
Enzymes -Answers:-proteins that act as catalyst to expedite
the chemical reactions that break down food into usable
substances
Hormones -Answers:-have key roles in many aspects of
digestion including regulating the sensations of hunger and
satiety, stimulating secretions and glucose uptake, modulating
digestive action and movement of food through the small
intestine, and including glycogen breakdown
Mouth -Answers:-Enzymes: salivary amylase, salivary lipase.
Major hormones: none
