Systems of the Body Flashcards
which system acts as a protective barrier and is responsible for excretions, absorption, temperature regulation, and vitamin D production?
the integumentary system (skin)
which system is responsible for structure, framework, protection, and mineral storage?
the skeletal system (bones)
which system is responsible for movement (by pulling on the skeleton) and generating heat?
the muscular system
which system is responsible for FAST communication and coordination? (ex. reacting to injury)
the nervous system
which system is responsible for SLOW communication and body regulation (ex. puberty)
the endocrine system
which system is responsible for the transport of nutrients, oxygen, and waste?
the cardiovascular system
which system is responsible for transport and protection?
the immune system
which system is responsible for gas exchange (oxygen in, CO2 out) and waste removal?
the respiratory system
which system is responsible for obtaining building materials for energy, storage, and repair?
the digestive/gastrointestinal system
which system is responsible for the filtration of blood and the excretion of waste?
the urinary system
which system is responsible for reproducing new life forms?
the reproductive system
what is the first term that defines life processes?
metabolism
what is the second term that defines life processes?
responsiveness to change
what is the third term that defines life processes?
movement
what is the fourth term that defines life processes?
growth
what is the fifth term that defines life processes?
differentiation/specialization of cells
what is the sixth term that defines life processes?
reproduction
what is homeostasis?
maintaining a consistent environment
what are feedback loops/systems responsible for?
regulation and response of the system
what are receptors responsible for?
detecting changes in the environment
what is the control center responsible for?
processing information and determining the body’s response
what is the effector responsible for?
carrying out changes determined by the control center
what are negative feedback loops?
the most common feedback loop; attempts to reverse changes in the body (ex. a message is sent to the anterior pituitary to send less TSH to the thyroid - in order to produce less hormones if thyroid hormones are too high)
what are positive feedback loops?
reinforcing changes being made in the body (ex. contractions during labor and delivery)
