What is the main organ of the nervous system?
The brain
What is the main organ of the integumentary system?
The skin
The bodies chemical messengers:
Hormones
Name the two kinds of heart chambers
Atria and ventricles
Function: To coordinate the body's systems by receiving and sending information while maintaining homeostasis.
This chemical moves through the synapse to transfer a signal from one neuron to another.
Neurotransmitter
What organ connects the mouth to the stomach?
The esophagus
T/F: Immune cells only respond to cells that are not from our body. Explain
False: immune cells can also fight cancer cells which ARE from our own bodies.

Function: To break down and absorb nutrients for the body's cells
Digestive system
What organ filters waste from blood in the excretory system?
The kidneys
How does perspiration (sweating) by the integumentary system help the body maintain homeostasis?
It helps the body regulate temperature, salt balance, or remove excess water.
Mystery Q: List the three body systems that work together to cause movement in the body!

List two things the liver helps to break down.
Medicines, nitrogenous molecules, alcohol, and fat (using bile)
Where is bile: produced? stored? used?
Liver - gallbladder - small intestine
Most organs in the endocrine system are called this
Glands
What is the name of the loop that sends deoxygenated blood to the lungs and then back to the heart?
Pulmonary circulation
What system works with the nervous system to coordinate the body's functions and maintain homeostasis? (It helps regulate processes such as growth, metabolism, and blood sugar levels.)
Endocrine System
