the thoracic cavity contains "what" that is located within the pleural cavity...
lung
the thoracic cavity contains "what" that is located overlying the heart....
thymus
which organ is commonly known as the windpipe?
trachea
which organ stores urine?
urinary bladder
how does the nervous organ system contribute to the patellar reflex?
uses nerves to help carry stimuli
how does the skeletal organ system contribute to the patellar reflex?
uses the spinal cord to help carry out the action
the abdominopelvic cavity has what that is located in the hypogastric region?
uterus
which organ transports blood to the heart?
veins
which of the following organ systems is correctly matched with one of its functions?
respiratory system-- transports oxygen and carbon dioxide
which abdominopelvic region is the liver found in?
right hypochondriac region
which abdominopelvic region is the right kidney found in?
right hypochondriac region
in the patellar reflex which component serves as the control center?
spinal cord
the abdominopelvic cavity has what located in the hypochondriac region?
spleen
which organ produces sperm?
testes
which of the following organs belong to more than one organ system?
Kidney
the sternum is _________ to the heart
anterior
the pituitary gland is _________ to the brain
deep
list three organ systems involved in the maintenance of blood calcium levels, and state the role of each organ system in the process
digestive system- absorbs nutrients into bloodstream skeletal system- blood cell production & stores calcium urinary system- filters waste products from the blood
what organ system does the gallbladder belong to? cavities?
digestive system; ventral cavity-> abdominal cavity
which of the following pairs of organ systems functions primarily to regulate body functions?
endocrine and nervous system
which abdominopelvic region is the stomach found in?
epigastric region
which organ transports food from the pharynx to the stomach?
esophagus
what organ system does the urinary bladder belong to? cavities?
excretory system; ventral cavity-> pelvic cavity
briefly describe one example of how the circulatory, respiratory, and digestive systems work together to maintain homeostasis
food/nutrients (digestive system)-> iron-> hemoglobin-> circulatory carries hemoglobin which oxygenate cells-> respiratory
which abdominopelvic region is the urinary bladder found in?
hypogastric region
the thymus is ________ to the thyroid gland
inferior
in the patellar reflex which component serves as the effector?
motor neurons
in the patellar reflex which component serves as the receptor?
muscle spindles
how does the muscular organ system contribute to the patellar reflex?
muscles help carry out action
is blood calcium regulation an example of negative feedback control or positive feedback control? Explain.
negative. if blood calcium increases too much, the parathyroid glands reduce parathyroid hormone production
distinguish between negative feedback mechanism and a positive feedback mechanism
negative: stimulus elicits a physiological response that opposes or counteracts the stimulus positive: output enhances the original stimulus
does the patellar reflex involve a negative feedback mechanism or a positive feedback mechanism?
negative; because this reflex results in restoration of natural position of the knee. (can be seen as homeostasis)
briefly describe one example of how the nervous, endocrine, and circulatory systems work together to maintain homeostasis
nervous system helps out with the brain and the brain helps keep everything working
what organ system does the brain belong to? cavities?
nervous system; dorsal cavity-> cranial cavity
the esophagus is ___________ to the trachea
posterior
the liver is ________ to the gallbladder
proximal
