Lang of Anatomy and Organ Systems Flashcards
anterior
ventral, towards the front
posterior
dorsal, towards the back
parietal
wall of cavity
transverse plane
horizontal into top and bottom, produces cross section
sagittal plane
vertically into left and right
frontal
vertically into front and back
abdominopelvic regions
right hypochondriac, epigastric, left hypochondriac
right lateral lumbar, umbilical, left lateral lumbar
right inguinal, pubic, left inguinal
integumentary system function
protects deeper organs from injury and drying out, excrete salts and urea, help regulate body temp and produce vitamin D
skeletal system function
protects and supports body organs and is a framework for muscles, blood cell formation, stores minerals
muscular system function
contract/shorten which generate movement of the body and heat
nervous system function
body detects change in environment and respond to information via activation of muscles/glands. use electrical signals to maintain homeostasis
endocrine system function
helps to maintain homeostasis in the body, produces chemical messengers that travel via blood to target organs, promotes growth and development in target regions of the body
cardiovascular system function
heart pumps blood and blood vessels transport it through body
lymphatic system function
returns fluid back to blood that was leaked from blood vessels. cleans blood from pathogens and other debris
respiratory system function
blood is supplied with oxygen and removes carbon dioxide
digestive system function
breaks down material that has been ingested that is then absorbed into blood and delivered to cells in other parts of the body. undigested material is removed from the body as fecal matter
urinary system function
eliminated nitrogenous wastes, maintains water, electrolyte, and acid/base balance of blood
reproductive system function
male: testes produces sperm and sex hormones
female: ovaries produce eggs and sex hormones, site of fertilizations
thymus function
body defenses, where T cells mature and become specializes, produces hormones that regulate development of T cells
thymus location
endocrine, lymphatic, mediastinum in thoracic cavity
heart function
pump blood through the body
heart location
cardiovascular, thoracic cavity, pericardial cavity
lung function
site of gas exchange, brings oxygen into bloodstream
lung location
respiratory, pleural cavity
trachea function
major airway of lower respiratory syst, exchanges air with outside environment
trachea location
respiratory, thoracic cavity, mediastinum
bronchi function
major airways of the lower respiratory syst, delivers oxygen rich air to the lungs and in reverse passes our oxygen poor air
bronchi location
respiratory, thoracic cavity
esophagus function
where food passes thru from pharynx to the stomach
esophagus location
digestive, thoracic cavity
diaphragm function
muscle used for breathing and separates the thoracic and abdominopelvic cavity
diaphragm location
respiratory syst, inferior portion of the thoracic cavity
