Which function necessary for life does this describe? metabolism excretion
Stimulus: produces a change in variable Effector: provides the means for the control center's response to the stimulus Input: sensory information sent to the control center Control center: determines the level at which a variable is to be maintained and analyzes the input to determine the appropriate output Response: effector feeds back to reduce the effect of the stimulus and returns the variable to homeostatic level Hemostasis is the process by which bleeding is stopped by the body. This process involves clot formation. Which of the following statements describes feedback regulation during clot formation? Select the correct answer. During blood clotting, the original stimulus is increased by positive feedback. During blood clotting, the original stimulus is decreased by positive feedback.
During blood clotting, the original stimulus is decreased by negative feedback. During blood clotting, the original stimulus is increased by negative feedback. - Correct Ans:✔✔ During blood clotting, the original stimulus is increased by positive feedback. Which of these carries out the commands of a homeostatic control center? nerve stimulus receptor effector - Correct Ans:✔✔ effector Which of these describes the effect of a negative feedback mechanism? pushes the variable farther away from the set point reduces the intensity of the initial stimulus extends the duration of the initial stimulus
changes the set point of a variable increases the effect of the initial stimulus reduces or stops the initial stimulus initiates a stimulus - Correct Ans:✔✔ reduces or stops the initial stimulus Which of the following cavities is NOT associated with the urinary bladder? abdominal cavity pelvic cavity ventral body cavity abdominopelvic cavity - Correct Ans:✔✔ abdominal cavity Which of these body parts is distal to the crural region? carpal region gluteal region acromial region tarsal region - Correct Ans:✔✔ tarsal region
