|
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?
|
movement
responsiveness growth reproduction respiration digestion absorption circulation assimilation excretion |
|
|
|
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?
|
water
foods oxygen heat pressure |
wfohp
|
|
|
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 oxygen?
|
a gas that makes up about 1/5 of ordinary air; it drives metabolic process
|
|
|
|
What is heat?
|
a form of energy
|
|
|
|
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) |
dv
|
|
|
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 |
ta
|
|
|
What makes up the thoracic cavity?
|
diaphragm
mediastinum parietal and visceral pleura parietal and visceral pericardium periocordial cavity |
dmppp
|
|
|
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
|
slsgksl
