ATI TEAS SCIENCE Questions And Answers
What are the two functions of epithelial tissue? Correct Ans - It can provide
covering or produce secretions.
What does epithelial tissue depend on in order to get food and oxygen? Why?
Correct Ans - Epithelial tissue depends on the diffusion from nearby capillaries
for food and oxygen because it does not have a blood supply.
Where is simple epithelium found in the body? Correct Ans - Simple epithelium
is found in places where absorption, secretion, and filtration occur.
What does stratified epithelium mean and what is its purpose? Correct Ans -
Stratified epithelium has more than one layer of cells. It serves as protection.
What are the three shapes of epithelial cells? Correct Ans - The three shapes
of epithelial tissue cells is squamos, cuboidal and columnar.
What is the function of connective tissue? Correct Ans - The function of
connective tissue is to connect different structures of the body.
Where does connective tissue get its blood supply from? What is the exception?
Correct Ans - It generally has it's own blood supply, but there are some
connective tissues, like ligaments, that do not get a blood supply.
What are the 4 types of connective tissues? Correct Ans - The 4 types of
connective tissues are bone, cartilage, adipose (fat), and blood vessel.
What are the three types of muscle tissue? Correct Ans - The 3 types of
muscle tissue are skeletal, cardiac and smooth
Out of the 3 types of muscle tissue, which one(s) supports voluntary control? Why?
Correct Ans - The only muscle tissue with voluntary control that is consciously
controlled by the brain is skeletal muscle. It has this process because it is connected
to the bones in the skeletal system.
Where are the voluntary movements of skeletal muscle, controlled from? Correct
Ans - Voluntary movements of skeletal muscle is controlled by the brain.
Is smooth muscle under voluntary or involuntary control? Correct Ans -
Smooth muscle does not have conscious, voluntary control.
Where is smooth muscle found? Correct Ans - Smooth muscle is found in the
walls of hollow organs, such as intestines, blood vessels, bladder and uterus.
What is the purpose of nervous tissue? Correct Ans - The purpose of nervous
tissue is that it provides the structure for the brain, spinal cord and nerves.
,What are nerves made up of? Correct Ans - Nerves are made up of neurons
that send electrical impulses throughout the body.
What cells help protect nervous tissue? Correct Ans - Support cells, such as
myelin, help protect nervous tissue.
What is an atom? Correct Ans - The smallest parts of elements that still retain
all the original properties of any element.
Atoms combine to form ___________. Correct Ans - Atoms combine to form a
molecule.
What is a molecule? Correct Ans - A molecule is a chemical bonding of atoms
that possesses its own characteristics independent of the atoms themselves.
What are cells made from and what are they? Correct Ans - Cells are made
from specific olecules that combine; they are the basic unit of all life
Cells combine in terms of function and type to form what? Correct Ans -
Tissues are made from cells of similar type and serve a similar function.
When two or more tissues work together to perform a specific function, what is
made? Correct Ans - An organ is made up of two or more tissue types working
together to perform a specific function.
At the organ level, what is possible? Correct Ans - At the organ level,
extremely complex functions are possible.
What is an organ system and how many do we have in our body? Correct Ans -
An organ system is where multiple organs work together to perform a task. We have
11 organ systems in our body
What is an organism? Correct Ans - It is the result of all organ systems working
together within the body. It is the highest level of organization.
What is another name for the circulatory system? Correct Ans - The circulatory
system is also called tthe cardiovascular system.
What does the circulatory system consist of? Correct Ans - The circulatory
system consists of the heart, blood vessels and blood.
What is the purpose of the circulatory system? Correct Ans - The circulatory
system supports the circulation and distribution of various substances throughout
the body.
How does the endocrine system affect the circulatory system? Correct Ans -
The endocrine system influences the blood pressure.
, How does the urinary system aid the circulatory system and how? Correct Ans -
The urinary system helps regulate blood volume and pressure by adjusting urine
volume.
What helps preserve vascular health in women? Correct Ans - Estrogen helps
preserve vascular health
How does the integumentary system interact with the cardiovascular/circulatory
system? Correct Ans - The IS allows heat to escape by dilating superficial
blood vessels
Where are blood cells formed? Correct Ans - Blood cells are formed in the
marrow of the bones in the skeletal system
What organs are in the digestive system? Correct Ans - The esophagus,
stomach, small and large intestinse, rectum and anus make up the digestive
system.
What does the digestive system manufacture and why? Correct Ans - The
digestive system manufactures enzmes that break down food so that the nutrients
can be easily passed into the blood for use throughout the body.
Where does absorption of nutrients take place? Correct Ans - In the digestive
system, the absorption of nutrients take place in the small intestine.
What is the colons job in the digestive system? Correct Ans - The colon
removes water from the waste remaining after the large intestine.
What does the liver do for the digestive system? Correct Ans - The liver
creates bile that helps break down fats.
What does the pancreas do for the digestive system? Correct Ans - The
pancreas delivers enzymes to the small intestine that aid digestion.
What is the function of glands in the endocrine system? Correct Ans - In the
endocrine system, glands secrete hormones that travel through the blood to organs
throughout the body.
What are a few glands that regulate processes such as growth and metabolism?
Correct Ans - Adrenal glands, thalamus, hypothalamus, thyroid, pituitary, and
pineal glands are glands that regulate process such as growth and metabolism
What are 3 organs that have endocrine functions, but are part of other body
systems? Correct Ans - The pancreas, testis, and ovaries have endocrine
functions but belong to other body systems.
What system provides a means of transportation for some hormones in the
endocrine system? Correct Ans - The lymphatic system provides a means of
transportation for some hormones
