Transcript The Circulatory System

The Circulatory System
Lesson 2: Standard 9a. Students know how
the complementary activity of major body
systems provides cells with oxygen and
nutrients and removes toxic waste products
such as carbon dioxide
What have we learned so far?
• The definitions of specialized
cells, tissues, organs, and
organ systems
• The body is kept in
homeostasis (balance) by the
actions of different organ
systems working together
• Feedback inhibition is the
mechanism for maintaining
homeostasis in the body

Using your iPads, go to www.awwapp.com to get to the online
whiteboard
Write in the answer to question 1 and hold your iPads so I can see
them.
1.
What are the three main parts of the circulatory system?
Now tap the menu button and tap clear to clear your whiteboard and
answer question 2. Hold up your iPads when you are finished so I can
see them.
2. What are the three types of blood vessels in the human circulatory
system?
Blood Vessels
• ______________
– carry oxygen-rich blood
away from the heart and to
the body
– have thicker walls to
withstand higher blood
pressure
• ______________
– carry oxygen-poor blood to
the heart
– have valves to prevent
blood from flowing back in
the wrong direction
• ______________
– are the smallest blood
vessels
– so narrow that blood cells
pass through in a single file
– deliver oxygen and nutrients
to all cells of the body
Blood Vessels
• arteries
