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
