QUESTIONS
1. If a person has a deficiency in calcium, how might this affect the skeletal
system's functions?
It will improve the framework for muscle movement.
It will have no effect on the skeletal system.
It will enhance the bones' ability to store minerals.
It may weaken the bones and impair their ability to support and
protect organs.
2. Describe the functions of simple cuboidal epithelium and where it is typically
located in the body.
Simple cuboidal epithelium is involved in gas exchange and is found in
the lungs.
Simple cuboidal epithelium functions in secretion and absorption
and is typically located in kidney tubules.
Simple cuboidal epithelium is primarily for protection and is found in
the skin.
Simple cuboidal epithelium is responsible for sensory reception and is
found in the brain.
3. Also known as fat tissue/ fatty tissue. They are composed of fat cells, or we
call them the adipocytes. The adipocytes' main function, since they are fats
and lipids in nature, is that they are energy-containing cells, so they have ATP.
Aside from being a source of energy, this type of tissue is also responsible for
cushioning your body and insulating the body, especially in winter or cold.
Areolar/loose connective tissue
, Dense connective tissue
Adipose tissue-connective tissue
4. What is the primary role of nervous tissue in the human body?
Stores nutrients
Produces hormones
Supports body structures
Transmits electrical impulses
5. Describe the main difference between exocrine and endocrine glands in
terms of their secretion methods.
Exocrine glands secrete products onto surfaces or cavities, while
endocrine glands release hormones into the bloodstream.
Exocrine glands produce hormones, while endocrine glands secrete
enzymes.
Exocrine glands are found only in the digestive system, while
endocrine glands are found throughout the body.
Exocrine glands are larger than endocrine glands.
6. What is the primary role of the nervous system in the human body?
Hormonal regulation
Respiratory function
Digestive process
Control system
7. Reticular connective tissue fibers:
, Are primarily elastin
Form tendon tendons and most ligaments
Form the soft internal skeleton that supports other fibers in
lymphoid organs
Are found in the skin
8. If a researcher is studying the nervous system, which levels of organization
would they primarily focus on?
Tissue, Organ, and Organ System
Organ System and Organismal
Chemical, Cellular, and Tissue
Chemical and Cellular
9. Describe how the cardiovascular system contributes to homeostasis in the
body.
The cardiovascular system stores energy in the form of fat.
The cardiovascular system protects the body from infections by
producing antibodies.
The cardiovascular system helps in digestion by breaking down food
into nutrients.
The cardiovascular system maintains homeostasis by regulating
blood flow, delivering oxygen and nutrients, and removing waste
products.
10. The primary function of the nervous system is:
To protect deep organs
, To detect changes in the internal and external environment and
respond appropriately
To provide body support and levers for muscle action
To cleanse the blood of pathogens
11. Which of the following would be the key feature for bone tissue?
Lining by connective tissue by both outer and inner surfaces
High presence of blood vasculatures
Mineralized ECM
High content of collagen type I
Bone cells are housing in lacunae
12. The body, at all times, attempts to maintain homeostasis. The best definition
of homeostasis is:
a process that maintains the stability of the human body's internal
environment in response to changes in internal and external
conditions.
a process that maintains the immune system's defenses.
a process in which the body resists change to its genetic structure.
a function via which the body breaks down glucose to use as energy.
13. Describe the significance of anatomical orientation terms such as 'ventral'
and 'dorsal' in the study of human anatomy.
These terms are only relevant in the context of animal anatomy, not
human anatomy.
Anatomical orientation terms like 'ventral' and 'dorsal' provide a
standardized way to describe the locations of structures in the
