Unit 3- Basic Body Systems
The Body Systems- A group of cells, tissues and organs,
coordinated to maintain life
To help us observe the effects of medications on our residents,
we need to understand the effects of medications on the
body systems. Use the "Body System Guide" from the email
and be sure to review the Unit 3 curriculum. Also focus
on the diseases of the cardiovascular system and respiratory system,
as meds are often prescribed for these common conditions.
The body system study guide from the email attachment clarifies
all you need to know for the actual Unit 3 quiz
