Thoracic cavity - correct answers-Contains the lungs and heart and is enclosed by the rib cage. The thoracic cavity is separated from the abdominal cavity by the diaphragm Abdominal cavity - correct answers-Contains most of the digestive organs - stomach, liver, pancreas, intestines - and some of the urinary structures - the kidney and the ureters. The upper boundary is the diaphragm and the lower boundary is the brim of the pelvis (landmark of the pelvis bones) Pelvic cavity - correct answers-Contains the bladder, anus and reproductive organs and is enclosed by the pelvis Abdominopelvic cavity - correct answers-Since there is no anatomical division between the 2 cavities they are occasionally referred to as 1 region Homeostasis - correct answers-The dynamic physiological process that helps people maintain an internal environment suitable for normal function Feedback loop - correct answers-A system used to control the level of a variable in which there is an identifiable receptor (sensor) control center (integrator or comparator) effectors, and methods of communication Variables - correct answers-Parameters that are monitored and controlled or affected by the feedback system Receptors or sensors - correct answers-Detect changes in the variable Control centers or integrators - correct answers-Compare the variable in relation to a set point and signal the effectors to generate a response. These centers sometimes consider info other than just the level of variable in decision making, such as time of day, age, external conditions, etc. Effectors - correct answers-Execute the necessary changes to adjust the variable Methods of communication - correct answers-Components of the feedback loop that are necessary in order for it to function. This often occurs through nerves or hormones. In some cases the receptors and control centers are the same structures so there is no need for these signaling modes in that part of the loop Feedback cycle - correct answers-Any situation in which a variable is regulated and the level of the variable impacts the direction in which the variable changes (i.e. increases or decreases) even if there is not clearly identified loop components Stimulus - correct answers-Change in the environment
