Organization of the Human Body Flashcards
science of body structures and the relationships among them
anatomy
the science of body functions–
how body parts work
physiology
The first 8 weeks of
development following
fertilization of an egg
embryology
what are the selected subspecialties of anatomy?
embryology
developmental biology
cell biology
surface anatomy
gross anatomy
systemic anatomy
neurophysiology
endocrinology
cardiovascular physiology
immunology
renal physiology
pathophysiology
The complete
development of an
individual from
fertilization of an egg to
death
developmental biology
Cellular structure and
functions
cell biology
Surface markings of the
body to understand
internal anatomy
through visualization and
palpation
surface anatomy
Structures that can be
examined without using
a microscope
gross anatomy
Structure of specific
systems of the body such
as the nervous
systemic anatomy
Functional properties of
nerve cells
neurophysiology
Hormones and how they
control body functions
endocrinology
Functions of the heart
and blood vessels
cardiovascular physiology
How the body defends
itself against disease causing agents
immunology
functions of the kidney
renal physiology
Functional changes
associated with disease
and aging
pathophysiology
what are the levels of structural organization?
- Chemical Level
- Cellular Level
- Tissue Level
- Organ Level
- System Level
- Organismal Level
What are the organ systems of the human body?
Integumentary
skeletal
muscular
nervous
endocrine
cardiovascular
lymphatic
respiratory
digestive
urinary
reproductive
Functions: protects the body; helps regulate body temperature; eliminates some wastes; helps make Vit D; and detects sensations such as touch, pain, warmth, and
cold.
integumentary system
Functions: supports and protects the body; provides a surface area for muscle attachments; aids body movements; houses cells that produce blood cells; stores
mineral and lipids
skeletal system
Functions: Produces body movements such as walking; stabilizes body position; generates heat
muscular system
Functions: Generates action potentials (nerve impulses) to regulate body activities; detects changes in the body’s internal and external environments, interprets changes,
and responds by causing muscular contractions or glandular secretions.
nervous system
Functions: Regulates body activities by releasing hormones which are chemical messengers transported in blood from an endocrine gland or tissue to a target
organ
endocrine system
Functions: Heart pumps blood through blood vessels; blood carries oxygen and nutrients to cells and CO2 and wastes away from cells and helps regulate acid-base balance, temperature, water content; blood
components help defend against disease
cardiovascular system
Functions: Returns proteins and fluid to blood; carries lipids from GI tract to blood; include structures where lymphocytes that protect against disease-causing
microbes mature and proliferate
lymphatic system
Functions: Transfers oxygen from inhaled air to blood and CO2 from blood to exhaled air; helps regulate acid-base balance of body fluids; air flowing out of lungs
through vocal cords produces sounds
respiratory system
Functions: Achieves physical and chemical breakdown of food; absorbs nutrients; eliminates solid wastes
digestive system
