Functions/processes that distinguish living from nonliving - correct answer Maintaining
boundaries, movement, responsiveness, digestion, metabolism, excretion, reproduction,
growth & development
Needs to maintain life - correct answer Nutrients, oxygen, water, appropriate
temperature, appropriate atmospheric pressure
Homeostasis;what two systems are most important for this - correct answer the ability to
maintain a stable internal environment; nervous & endocrine
Negative feedback; ex - correct answer physiological response in the opposite direction
of the initial stimulus; ex. Thermostat
Positive feedback; ex - correct answer output exaggerates the responses; graphs goes
up; ex. Bold clotting
Anatomical position - correct answer erect spine, arms supinated, knees together, feet
laterally rotated
Sagittal plane - correct answer divided down the middle of the body, two symmetrically
halves, closer to middle of body = medial, further away from to middle of body = lateral,
in the middle of body = intermediate
Frontal plane - correct answer divides body into front and back halves, front of body =
anterior, back of body = posterior, (in animals) back side = dorsal, stomach side =
ventral
Transverse plane - correct answer divides body at the waist, above the waist = superior,
below the waist = inferior, (in animals) closer to head = cranial, closer to tail = caudal
Superior - correct answer above
Inferior - correct answer below
Anterior - correct answer front
,Posterior - correct answer back
Proximal - correct answer closer to origin
Distal - correct answer closer to end
Superficial - correct answer closer to surface of body
Deep - correct answer further from surface of body
Medial - correct answer closer to middle of body
Lateral - correct answer further from middle of body
Two main body cavities - correct answer dorsal & ventral
Dorsal cavity contains - correct answer cranial-->skull encases brain
Vertebral-->vertebral column encases spinal cord
Ventral cavity contains which two sub cavities; what separates them - correct answer
thoracic-->heart and lungs
Abdominopelvic-->separated from thoracic by diaphragm
Thoracic cavity contains - correct answer pleural-->each hold a lung
Mediastinum (pericardial)-->encloses hearts and surrounds esophagus, trachea, & other
thoracic organs
Abdominopelvic cavity contains - correct answer abdominal-->stomach, intestines,
spleen, and liver
Pelvic-->urinary bladder, reproductive organs, and rectum
Serosa membrane; lines what kind of body cavities - correct answer parietal-->lines
