what is chemical digestion?
when your body breaks down food into nutrients
Smooth muscles

arteries
Carry blood that has oxygen and nutrients to all the parts of the body.
Lungs
The organ which allows oxygen to get to the blood and helps remove waste gasses such as carbon dioxide.
ligaments
connect bone to bone
what is mechanical digestion?

skeletal muscle
Muscle tissue that is attached to the bones. This muscle is striated and under voluntary control.
blood
Composed of red blood cells, white blood cells, platelets and plasma that have different functions.

cartilage

Saliva
The liquid produced in the mouth that aids Chemical Digestion.
tendon
Connects muscle to bone
circulatory
Its function is to pump blood through the body.
Alveoli
Clusters of thin-walled sacs surrounded by capillaries allow for a quick exchange of oxygen and carbon dioxide.
hinge
type of joint; ex: knee, elbow
Esophagus
The tube connecting the mouth to the stomach. Food is moved through a process called Peristalsis.
Involuntary Muscle
