Which of the following sequences is correct regarding feedback mechanisms?
Effectors send information to receptors, which alert the control center.
Receptors send information directly to effectors, which alert the control center.
The control center sends information to receptors, which alert effectors.
Receptors send information to the control center, which regulates effectors
Which of the following descriptions defines homeostasis?
Maintaining a stable internal environment
The sum of all the body’s reactions
The goal of positive feedback mechanisms
Creating energy in the form of ATP
In general, what is the consequences if the body does not closely regulate negative feedback mechanisms?
New energy cannot be created.
Homeostasis is not maintained.
Effectors do not receive input.
Blood will not coagulate
What is a physiological example of a positive feedback loop?
(Where you want more of it...)
Blood glucose levels decrease to normal range with the help of insulin.
Evaporation cools the body temperature down to a normal set point.
Oxytocin causes enhanced uterine contractions.
Calcitonin is released to decrease calcium.
When we refer to the body as being in a state of homeostasis, we are saying that —
the physiological ranges of the body (like body temperature) never change
both the anatomy and physiology of the body are unchanged
the body stays in a healthy state, despite having to adapt to constant changes
the body is in a state of static equilibrium

Torsion
This place receives and analyzes information from sensory receptors, then sends a command stimulus to an effector to maintain homeostasis.
effector
receptor
control center
The unit that receives a command stimulus from the control center and causes an action to help maintain homeostasis is called this.
effector
receptor
control center
Organ systems cooperate to maintain homeostasis through a process called
homeostatic mechanisms
metabolic rate
positive feedback
effector
The speed at which the body consumes energy is called the -
homeostasis
positive feedback
metabolic rate
receptors
This relates to all chemical reactions that occur within an organism to maintain life.
metabolism
homeostasis
negative feedback
positive feedback
The mechanism that reverses a condition that has exceeded the normal homeostatic range.
negative feedback
positive feedback
