What is anatomy?
the study of the form, or structure of body parts
What is physiology?
the study of the function of these parts and how they work together to sustain life
What are the characteristics of life?
What is movement?
the change in an organism position or traveling from one place to the next or the motion of internal parts

ex. walking, propelling of fluids
What is responsiveness?
an organism's ability to sense changes taking place inside or outside its body and to react to these changes
What is growth?
an increase in body size, usually without any important change in shape
What is reproduction?
the process of making a new individual, as when parents produce an offspring, repairing body cells and tissues
What is respiration?
the process of obtaining oxygen, using oxygen to release energy from food substances, and removing the resultant gaseous wastes
What is digestion?
chemically and mechanically breaks down food substances into simpler forms that cells can absorb and use
What is absorption?
the passage of substances through certain membranes, as when digestive products pass through the membrane that lines the intestine and enter body fluids
What is circulation?
the movement of substances within the body in body fluids
What is assimilation?
the changing of absorbed substances into forms that are chemically different from those that entered body fluids
What is excretion?
the removal of wastes that body parts produce as a result of their activities
What are the maintenances of life?




What is water?
most abundant, needed for metabolism, transporting substances and regulating body temperature
What are foods?
substances that provide the body with necessary chemicals (nutrients) in addition to water

What is pressure?
an application of force to something
What is homeostasis? and give an example
the maintenance of a stable internal envirionment. this environment is amintained by the homeostatic mechanism a series of events that regulates body temperature.

ex. if a person is cold the brain senses this and triggers heat generating and heat conserving activities
What happens if a person gets too hot? what is the negative feedback?
you sweat and your breathing rate increases

you're sweating to cool the body down
What are the major body cavities?
dorsal cavity

ventral cavity (thoracic cavity and abdominopelvic cavity)
Where is the dorsal cavity and what does it do?
towards the back cranial cavity (houses the brain) vertebral canal (contains the spinal cord)
What are the parts of the ventral cavity?
thoracic cavity

abdominopelvic cavity
What makes up the thoracic cavity?


parietal and visceral pleura

parietal and visceral pericardium

periocordial cavity
What is the diaphragm? What is it's function?
a sheet like structure composed largely of skeletal muscles and collective tissues

it separates the thoracic and the abdominopelvic cavity
What is the mediastinum? give examples.
a membrane that splits the cavity into two compartments

ex. heart and lungs
What are the parietal and visceral pleuras?
membranes that line and cover the lungs
What are the parietal and visceral pericardium?
membranes that surround and cover the surface of the heart
What is the pericordial cavity?
a fluid filled space between the parietal and visceral pericardium
What is the abdominopelvic cavity?
membranes that include the parietal and visceral peritoneum
What is the peritoneal cavity?
a space between the two membranes
What are the organs of the abdominal cavity?
stomach, liver, spleen, gallbladder, kidneys, small intestine and portion of the large intestine
What are the viscera of the pelvic cavity?
portion of the large intestine, urinary bladder and internal reproductive organs
What are the levels of organization?
organ systems
