basic functions of all living things - ANS--responsiveness
-growth
-reproduction
-movement
-metabolism
anatomy - ANS-structure
-cutting open
study of the structure of the human body
-external and internal
-physical relationships between body parts
physiology - ANS-study of function of anatomical structure
-how organs work separate and together
gross anatomy - ANS-include:
-surface anatomy: what you can see on surface, study of general form and superficial
markings
-regional anatomy: study of all superficial and internal features of a specific region of the
body
systemic anatomy: study of the structure of major organ systems
microscopic anatomy - ANS-includes:
-cytology: study of cells
-histology: study of tissues and organs under a microscope
levels of organization ** - ANS--molecule-cell-tissue-organ-organ system- organism
levels of organization : chemical level - ANS--Atoms are the smallest stable units of
matter
-Atoms combine to form molecules
-Molecular shape defines function
levels of organization : cellular level - ANS--Cells are the smallest living units
-Cellular structures have specific functions
-Different cell types have different functions
levels of organization:
tissue level - ANS--A collection of cells working together to perform a specific function
-4 basic tissue types
Epithelial, connective, muscle, and nervous tissues
levels of organization:
organ level - ANS-Organ: Two or more tissues working together to perform specific
functions
levels of organization:
organ system level - ANS-Two or more organs working together to perform specific
functions
levels of organization:
organism level - ANS-all organ systems working together to maintain health
the integumentary system - ANS--skin
-Protects against
environmental hazards
-Helps control body temperature
-Sensory information
the skeletal system - ANS--bones
-Provides support
-Protects tissues
-Stores minerals
-Forms blood cells
-calcium is important for muscle function
-body regulate Ca+ if not enough it will take from bones
-axial skeleton: skull and ribs
-appendicular skeleton: limbs
the muscular system - ANS--Allows for movement
-Provides protection and support
-Produces heat when burning energy
-skeletal voluntary muscle
-muscle contract when cold
"shivering"
include: axial muscle, appendicular muscle, tendons
the nervous system - ANS--Directs immediate responses to
stimuli, usually by coordinating the
activities of other organ systems
-Provides and interprets sensory
information
-Cognitive functions
-central nervous system: brain and spinal cord
-peripheral nervous system:
peripheral nerves
the endocrine system - ANS--PRODUCE HORMONES
-Directs long-term changes in activities of other organ systems
-all endocrine glands
pituitary gland - ANS-tell adrenal gland what to do,
produce critical hormones
paranthyroid gland - ANS-regulate calcium levels
adrenal gland - ANS-produce hormones
pineal gland - ANS-produce melatonin
thyroid gland - ANS-metabolism , growth
thymus - ANS-produce WBC
pancreas - ANS-insulin and glucagon is reproduced
regulate blood sugar helps in digestion
the cardiovascular system - ANS-Transports cells and dissolved
materials, including nutrients,
wastes, and
gases
-carry blood: carry oxygen to tissues
-heart, capillaries, artery , vein
the lymphatic system - ANS--immune system
-Defends against
infection and disease;
returns tissue fluid to the bloodstream
lymph nodes - ANS-processing center for immune cells
spleen - ANS-recycle RBC, fight bacteria
the respiratory system - ANS--Delivers air to sites where gas exchange can occur
-Produces sound
-deliver air with oxygen
-produce sound and sense of smell
larynx - ANS-house vocal cords
trachea - ANS-provide air flow
bronchi - ANS-passageway to lungs
the digestive system - ANS-Processes food and absorbs nutrients
