what is the teological approach
why
what is the mechanistic approach
how
physiology
is the study of functions of the body
anatomy
study of body parts
levels of physiology
atomic
cellular
tissue
organ
body system
what is the atomic level
simple atoms forms molecules
what is the cell level
smallest structure within the body
what is the tissue level
when cells weave together and form tissues
what are the types of tissue level
Muscle, nervous, epithelial and connective tissue
what does muscle tissue consist of
skeletal, cardiac, and smooth muscle
what does skeletal muscle do
works with tendons and ligaments
work with weight of the body as well as ensure movement
what does cardiac muscle do
found in the heart helps contract and pump blood throughout body
what does smooth muscle do
internal movement
who invented physiology
hehe got yah
what is nervous tissue divided into
CNS and PNS
CNS what is it composed of
the brain and spinal cord
what is the function of epithelial tissue
forms epithelial sheets
cover and line the organ
what is lumen
hollow Centre
what is lumen formed from
lining of the epithelial sheets
how are glands formed
by epithelial cells
what are the two different routes epithelial glands can take to become
exocrine and endocrine
an example of exocrine gland
sweat gland
example of endocrine gland
pituitary gland
where does the endocrine gland secrete
to the blood
where does the exocrine gland secrete
outside the body
what does connective tissue do
supports and anchors our body parts
what are the two types of connective tissue
loose connective tissue and dense connective tissue
what is loose connective tissue
attaches body parts so they are not hanging loose example fat adipose
what is dense connective tissue
anchoring our body and giving us shape,
rigid connective bone tissue
what is an organ
formed after these levels is tool to survive
how many organ systems
11 organ systems
what forms with all the levels of physiology
an independent organism a human being
what is homeostasis
makes sure we have a stable environment
minimizes and responds to change
what governs homeostasis
bodyfluids (ICF ECF)
Controls
feedback mechanisms
what does ecf consist of
interstistital fluid and plasma
what are the controls
intrinsic : innate self serving
extrinsic : outside , governed and helped by nervous system and endocrine system
what are the types of feedback
positive feedback and negative feedback
what is positive feedback
reinforces or amplifies the change
what is negative feedback
reverses and completely opposes the change
what is feedforward
anticipation of change
what can the disruption of home stasis cause
death illness and pathophysiology
