d. ORGAN SYSTEMS
Match the Organ System with its function
coordinates the body's responses to changes in its internal and external environments
f. eliminates wastes and maintains homeostasis
a. stores mineral reserves and provides a site for blood cell formation
g. serves as a barrier against infection and injury
e. controls growth, development, metabolism, and reproduction
i. helps protect the body from disease
d. helps produces voluntary movement, circulate blood, and move food
h. coverts food so it can be used by cells
k. brings materials to cells, fights infection, and helps to regulate body temperature
b. provides oxygen and removes carbon dioxide

Thermostat senses temperature change and switches off heating system
Thermostat senses temperature change and switches on heating system
Room Temperature Decreases
Room Temperature Increases
True or False
The part of the brain that monitors and controls body temperature is the hypothalamus.
What happens if nerve cells sense that the core body temperature has dropped below 37 degrees C?
The hypothalamus produces chemicals that signal cells throughout the body to speed up their activities.
What happens if the body temperature rises too far above 37 degrees C?
The hypothalamus slows down cellular activities, minimizing the production of heat.
