In humans, the gases oxygen and carbon dioxide must be exchanged between the environment and cells. During this exchange, oxygen is delivered to the red blood cells so that they can function properly in the blood stream. Which two body systems are working together to achieve this goal?
Endocrine and Reproductive
Skeletal and Muscular
Respiratory and Circulatory
Digestive and Excretory

Nervous, Skeletal
Nervous, Digestive
When you get cut, your skin cells release hormones that signal platelets to come and stop the bleeding. Platelets then release more hormones that signal even more platelets to help stop bleeding. The hormone signals continue growing until the cut is closed.
Positive Feedback Response
Negative Feedback Loop
What is an example of a positive feedback mechanism?
What is an example of a negative feedback mechanism?
