- For our assignment, research about the different types of the blood vessels and their function.
- You may now leave.
- The next day
- Where's Ben? Oh guys do you have the research about the blood vessels?
- Oh he's sick, and yes I did some research about that
- Me too!!
- So you all have 10 mins to brainstorm all your research
- CIRCULATORY SYSTEM
- -BLOOD VESSELS
- Mine is the capillary
- Capillaries connect the arteries to veins.
- I will talk about the artery and its main function
- So they continue to brainstorm, after 10 mins the teacher told them to comeback now
- Artery carry oxygenated blood away from the heart
- Veins carry the blood back to the heart.
- And mine will be the veins, right now we'll just share our thoughts about the type that we'll share
- Arteries carry oxygenated blood away from the heart. Smooth interior layer of epithelial cells that allows blood to flow easily.
- Arteries also contain a strong, muscular middle layer that helps pump blood through the body.
- Unlike arteries, veins contain valves that ensure blood flows in only one direction.
- Veins carry the blood back to the heart. They’re similar to arteries but not as strong or as thick.
- The capillaries then deliver the waste-rich blood to the veins for transport back to the lungs and heart.
- Capillaries connect the arteries to veins. The arteries deliver the oxygen-rich blood to the capillaries, where the actual exchange of oxygen and carbon dioxide occurs.
- These vessels transport blood cells, nutrients, and oxygen to the tissues of the body. They also take waste and carbon dioxide away from the tissues. The circulatory system does a very important job in your body. Your heart and blood vessels is essential to keeping your body functioning.
