Test 1 Flashcards
Anatomy
Study of body structure
Physiology
Study of body functions
6 levels of organization
Chemicals > cells> tissues> organs> organ systems > organism
4 tissue groups
Epithelial, connective, muscle and nerve
Epithelial tissue
Skin
Connective tissue
Supports and connects parts of the body (blood, bone, cartialige)
Muscle tissue
Smooth - internal organs
Cardiac - heart
Striated - skeletal muscles
Nerve tissue
Generates electrochemical impulses that regulate body function
What are the 11 organ systems?
Integumentary, skeletal, muscular, nervous, endocrine, cardiovascular, lymphatic, respiratory, digestive, urinary, and reproductive.
Integumentary system
Barrier to prevent pathogens and prevent excessive water loss (skin, hair)
Skeletal system
Supports body, protects internal organs, provides framework for muscles (bones, ligaments)
Muscular system
Moves the skeleton, produces heat (muscles and tendons)
Nervous system
Regulates body functions through electrochemical processes (brain, eyes, ears, nerves)
Endocrine system
Regulates body through hormones ( thyroid gland, pituitary )
Cardiovascular system
Transports O2 to tissue and removes waste products ( hearts, blood, arteries)
Lymphatic system
Returns tissue fluid to the blood, destroys pathogens ( spleen, lymph nodes)
Respiratory system
Breathing, - exchanges oxygen and carbon dioxide between air and blood
Digestive system
Turns food into simple chemicals that can be absorbed and used (stomach, colon, liver)
Urinary system
Removes waste and regulates pH balance of blood (kidneys, bladder, urethra)
Reproductive system
Produces egg or sperm and in women provides site for developing the embryo. (Ovaries, uterus) (testes, prostate gland)
Negative feedback
Outside source out of range triggers automatic response to correct situation
Positive feedback
Stimulus produces response that exaggerates change in original conditions rather than opposing it (labor and delivery)
Abdomen
External stomach
Axillary
Underarm
Buccal
Mouth
Oris
