homeostasis
is a muscular sheet that divides the ventral body cavity into the thoracic and abdominal cavity
diaphragm
directly causes mechanical motion
Muscular
responds to environmental changes by transmitting electrical impulses
Nervous
provides support and levers for muscles to work on
skeletal
protects underlying organs form mechanical damage and synthesizes vitamin D
integumentary
controls the body with chemical molecules called hormones
endocrine
delivers oxygen and nutrients to the tissues
cardiovascular
produces antibodies that neutralize foreign substances
immune
removes filters excess fluid from tissues
lymphatic
contains the esophagus, pharynx, and liver
digestive system
contains the ureters and urethra
urinary system
contains arteries, capillaries, and veins
cardiovascular system
involves a receptor to detect stimulus and effector that responds to stimulus, by communicating with a control center whose activity has an effect on the initial stimulus
homeostatic regulation
detects a particular stimulus
receptor
responds to stimulus by communicating with a control center
effector
a structure that is composed of two or more tissues
organ
spaces within the joints
synovial cavities
serous membranes consist of two membranes:
- parietal serosa membrane
2. visceral serosa membrane
membrane that covers the surface of the organs
parietal membrane
membranes that line the walls of cavities that contain organs
visceral serosa
membrane surrounding the heart
pericardium (visceral serosa)
membrane surrounding the lungs
pleura (visceral serosa)
surrounds most digestive organs of the abdomen

responsiveness
back of the elbow
olecraneal
heel region
calcaneal
broad term for all chemical reactions that occur within body cells
metabolism
when body temperatures are too _____, chemical reactions can slow down
low
if body temperatures are too______, body proteins will lose characteristics and shape, and stop functioning.
high
help prevent sudden severe changes within the body
negative feedback mechanism
type of feedback loop which will enhance the initial step in the chain of events, i.e. hypertension leads to arteriosclerosis, which increases peripheral resistance to blood flow, which increases hypertension.
positive feedback loop
