Q

Within our Efferent Division, there are 2 systems

A

Somatic – voluntary & starts with brain (you tell yourself to do it)

Automatic – involuntary (you do not have to tell your digestive system to digest your food, it just does )

Q

circulation through the chambers

A

deoxygenated blood enters the right atrium, then leaves into the right ventricle, leading into the lungs, oxygenated blood enters the left atrium which then goes into the left ventricle which distributes to the rest of the body
