The stomach is made up of ___ tissues - Answer 4; nervous, muscle, epithelial, and connective
What is involved with homeostasis - Answer temp, ph, blood sugar, osmotic pressure, blood
O2/CO2, and calcium
Homeostasis - Answer is continuously disturbed by external or internal stimuli, body systems
monitor this through positive and negative feedbacks
Homeostasis sensor - Answer detects changes and sends signals to the control center
Homeostasis control center - Answer sets the range of values which a variable should be
maintained, receives info from sensors and sends to effectors
Homestasis effector - Answer responds to signals from a control center to effect change in a
variable
Homeostatic imbalances - Answer disturbances in homeostasis can lead to disease or death if
uncorrected
, Negative feedback loop - Answer stimulus, sensor, control, effector
Negative feedback - Answer returns regulated variables to within normal range of values (body
temp)
Positive feedback - Answer increase/reinforce initial stimulus on regulated variable (blood
clot)
Childbirth is a - Answer positive feedback loop
Endocrine signaling - Answer Cells/glands release hormones that act on distant target cells in
the body via blood vessels.
Paracrine signaling - Answer a cell produces a signal to induce changes in nearby cells
Autocrine signaling - Answer the target cell is also the secreting cell
Juxtacrine - Answer signals act through direct stimulation of the adjacent cells
