TEAS EXAM 7 QUESTIONS WITH VERIFIED
ANSWERS 100% LATEST 2026
what do red blood cells contain? CORRECT ANSWER hemoglobin
bicarbonate buffer system CORRECT ANSWER most important buffer system that
keeps blood pH from changing drastically
What do white blood cells do? CORRECT ANSWER -They can change shape to
ingest microbes - this process is phagocytosis
-Others produce antibodies to fight microbes
-Some produce antitoxins to neutralise any toxins produced by the microbes
-They have a nucleus
How does blood flow through the cardiovascular system? CORRECT ANSWER
starting in the left ventricle, oxygenated blood is pumped through the body.
As it flows through the arteries to capillaries, it transports oxygen to the tissues and
picks up carbon dioxide.
Then, the deoxygenated blood returns to the heart through veins. It enters the hearts
right atrium and then flows into the right ventricle. Then it pumps the blood towards the
lungs through arteries where it picks up oxygen and drops off co2.
It finally returns to the heart through the left atrium using veins and starts the cycle over
again.
What is the purpose of the digestive system? CORRECT ANSWER Is to aid the body
in digestion and absorbtion
where does the digestive system begin at? CORRECT ANSWER mouth
mechanical digestion CORRECT ANSWER Physical breakdown of large pieces of
food into smaller pieces
Bolus CORRECT ANSWER A term used to describe food after it has been chewed
and mixed with saliva
deglutition CORRECT ANSWER swallowing
Peristalsis CORRECT ANSWER contractions of smooth muscles that provide the force
that moves food through the esophagus toward the stomach
,What is the stomach made of? CORRECT ANSWER smooth muscle
Chyme CORRECT ANSWER mixture of enzymes and partially-digested food
What are the three main secretions of the stomach? CORRECT ANSWER mucous,
hydrochloric acid , and pepsinogen
what does the mucous in the stomach do? CORRECT ANSWER lines the stomach
What is pepsin? CORRECT ANSWER an enzyme that breaks down proteins
small intestine function CORRECT ANSWER Absorbs most nutrients; Main absorption
organ of the digestive tract
duodenum CORRECT ANSWER first part of the small intestine
where does bile come from? CORRECT ANSWER gallbladder
What does microvilli do? CORRECT ANSWER increases surface area for absorption
what hormones are involved in digestion ? CORRECT ANSWER Gherlin - induces
hunger
leptin - sensation of satiety
what enzymes are involved in digestion? CORRECT ANSWER Amylase: produced in
the mouth in saliva. helps to break down large starch molecules into smaller sugar
monomers.
Pepsin: produced in the stomach. pepsin helps break down proteins into amino acids
Trypsin: produced in the pancreas. trypsin breaks down proteins.
Pancreatic lipase: produced in the pancreas. Used to break apart fats/lipids/
Deoxyribonuclease and ribonuclease: produced in pancreas. break bonds in nucleic
acids like DNA and RNA.
Bile is not necessarily an enzyme but bile acids help to break down fat. Made in the liver
and stored in the gallbladder. Secreted into intestine during digestion to emulsify fats
where does the breakdown of proteins begin? CORRECT ANSWER stomach
What is the nervous system? CORRECT ANSWER The master controlling and
communicating system of the body
, CNS (central nervous system) CORRECT ANSWER brain and spinal cord
PNS (peripheral nervous system) CORRECT ANSWER the sensory and motor
neurons that connect the CNS to the rest of the body
Axon CORRECT ANSWER A threadlike extension of a neuron that carries nerve
impulses away from the cell body.
Dendrites CORRECT ANSWER Branchlike parts of a neuron that are specialized to
receive information.
Synapse CORRECT ANSWER A junction where information is transmitted from one
neuron to the next.
autonomic nervous system CORRECT ANSWER A subdivision of the peripheral
nervous system. Controls involuntary activity of visceral muscles and internal organs
and glands.
somatic nervous system CORRECT ANSWER A subdivision of the peripheral nervous
system. Enables voluntary actions to be undertaken due to its control of skeletal
muscles
which of the following types of nerves sends messages to the brain? CORRECT
ANSWER sensory
What do motor neurons do? CORRECT ANSWER carry impulses from the brain and
spinal cord to muscles and glands
what is the muscular system? CORRECT ANSWER Consists of skeletal muscles,
tendons that connect muscles to bones, and ligaments that attach bones together to
form joint
Three types of muscle tissue CORRECT ANSWER skeletal, cardiac, smooth
skeletal muscle CORRECT ANSWER often attaches to the bone and is involved in the
movement of bones
striated and very strong
the only voluntary muscle in the whole body
cardiac muscle CORRECT ANSWER Involuntary muscle tissue found only in the
heart.
intercalated discs
