# Define this human body system Respiratory
collects oxygen and releases carbon dioxide
46
# Define this human body system Male Reproductive
makes and gives the sperm to the female reproductive system
47

uses sperm to fertilize the egg then develops and makes it grow into a human
48
# Define this human body system Endocrine
Makes chemical messages
49
# Define this human body system Nervous
collects information and responds with electrical messages
