functions of the integumentary organ system
protects against environmental hazards
regulates body temperature
provides sensory info
major organs of the integumentary organ system
skin
hair
sweat glands
nails
functions of the skeletal system
provides support and protection for other tissues
stores calcium and other minerals
forms blood cells
major organs of the skeletal system
bones
cartilages
assosiated ligaments
bone marrow
major functions of the muscular system
provides movement
provides protection and support for other tissues
generates heat that maintains body temp
major organs of muscular system
skeletal muscles
and assosated tendons
funvtions of the nervous system
directs immediate response to stimuli
coordinates or moderates activites of other organ systems
provides and interprets sensort information about external conditions
major organs of the nervous system
brain
spinal cord
peripheral nerves
sense organs
functions of the endocrine system
directs long-term changes in the activities of other organ systems
adjusts metabolic activity and energy use by the body
controls may structural and functional changes during development
major organs of the endocrine system
pituatary gland
thyroid gland
pancreas
adrenal gland
gonads
endocrine tissues in other systems
functions of the cardiovascular system
distrutes blood cells, water and dissolving materials including nutrients, waste products, O2 and CO2
distributes heat and assists in control of body temp
functions of the lymphatic system
defends against infection and disease
returns tissue fluids to the bloodstream
major organs in lymphatic system
spleen
thymus
lymphatic vessels
lymph nodes
tonsils
functions of respiratory system
delivers air to alveoli
provides oxygen to bloodstream
removes CO2 from bloodstream
proudeces sounds for communication
major organs in respiratory system
nasal cavities
sinuses
larynx
trachea
bronchi
lungs
alveoli
major functions of the digestive system
processes and digest food
absorbs and conserves water
absorbs nuntrients
stores energy reserves
major organs in digestive system
teeth
tongue
pharynx
esophagus
stomach
small intestine
large intestine
liver
gallbladder
pancreas
functions of urinary system
excretes waste products from the blood
controls water balance by regulating volume of urine produces
stores urine prior to voluntary elimination
regulates blood ion concentrations and pH
major organs of the urinary system
kidneys
ureters
urinary bladder
urethra
major organs of male reproductive system
testes
epididymides
ductus deferentia
seminal vesicles
prostate gland
penis
scrotum
major functions of the male reproductive system
produces male sex cells (sperm), seminal fluids and hormones
sexual intercourse
functions of the female reproductive system
produces female sex cells (oocytes) and hormones
supports developing embroyo from conception toe delivery
provides mil to nourish newborn infant
sexual intercourse
major organs of the female reproductive system
ovaries
uterine tubes
uterus
vaguna
labia
clitoris
mammary glands
collection of tissues makes up
organs
four types of tissues
nervous
muscle
epithelial
connective
epithelial tissues
found where alot of absorption and excretion taking place
tend to form barrier of which solutes and water can pass across
lining of GI tract organs and other organs
skin surface
connective tissue
provide structure and support to body
energy storage
space filler
fat and other soft padding tissue
bone
tendon
muscle tissue
cardiac muscle- heart
smooth muscle
skeletal muscle
muscle: movement and contractility
nervous tissue
excitable cells- process incoming info and cause responses via variety of signals
brain
spinal cord
nerves
total body water
60% body weight
70kg body mass
42L total body water
total body water :
intracellular fluid 1/3 28L
extracellular fluid 2/3 14L
extracellular fluid
extravascular fluid 3/4
plasma 1/4
extravascular fluid
interstitial fluid- outside blood system and cells
interstitial fluid (outside cell) and plasma
Na+, Cl-
HCO3- (bicarbonate) buffer
intercellular fluid
much less Na+ and much more k+
much less Cl- and much more phosphate
intracellular fluid ICF
system that includes all fluid enclosed in cells by their plasma membranes
extracellular fluid ECF
surrounds all cells in the body
extracellular fluid’s two primary constituents
plasma: fluid component of blood
interstitial fluid: (IF) that surrounds all cells not in blood
