Homeostasis- Feedback loops

What is the point of a feedback loop?

• To provide the body with more energy

• To provide the body with more food

• To make sure the conditions in the body are always changing

• To make sure the conditions in the body remain stable

According to the feedback loop, what does high blood sugar promote?

• Insulin Release

• Glucagon Release

• Insulin Uptake

• Glycogen Uptake

In this body temperature feedback loop, which of the following is the afferent pathway?

• Sweat glands releasing sweat

• Running outside in warm temperatures getting overly hot.

• The brain sending a signal to the sweat gland

• Your body would release lots of heat.

What happens if stretch receptors are activated in the uterus?

• Oxytocin will cause uterine muscles to relax

• Contractions will get weaker

• The baby will be born later than normal

• The brain will signal for the release of oxytocin

The two types of feedback systems that help organisms maintain homeostasis are:

• positive and negative 
• receptor and effector
• static and dynamic
• minor and major

Maintaining body temperature is an example of a:

• negative feedback loop
• positive feedback loop

The process of childbirth is an example of:

• negative feedback loop
• positive feedback loop

The "cause" for something to happen is the

• response
• effect
• stimulus
• homeostasis

The "effect" of a given stimulus is the...

• response
• stimulus
• cause
• result

When glucose levels in the blood rise, your brain sends a signal to your pancreas. The pancreas releases insulin, which opens channels in cell membranes to allow glucose to enter the cell, lowering blood sugar levels. 

• Positive Feedback Response
• Negative Feedback Loop
