This webquest is created by Dyna Marie Falsado.My goal is to shared to my student's on how to circulate th blood. And also to let them to feel their pulse.
Introduction
What is Circulatory System?
The circulatory system, also called the cardiovascular system or the vascular system, is an organ system that permits blood to circulate and transport nutrients (such as amino acids and electrolytes), oxygen, carbon dioxide, hormones, and blood cells to and from the cells in the body to provide nourishment and help in fighting diseases, stabilize temperature and pH, and maintainhomeostasis. The study of the blood flow is called hemodynamics. The study of the properties of the blood flow is calledhemorheology.

Task
1.From what source do cells get their food?
2.Which type of blood vessels carries blood away from the heart?
3.Where does the oxygen rich blood enter first in the heart?
4.Why is blood that flows from the lungs to the heart bright red rather than dark red?
5.Why is oxygen important to blood and to the cells?

| Procedures: Student Information: |
Ask students to identify the strongest muscle of the body. Allow students to give their ideas and then explain that the correct answer is the heart. Show students diagram of the heart and share the background information with them.
Explain that as the blood is pumped through the arteries, you can feel the artery walls stretch and relax. Ask students what this is called. Entertain their ideas and clarify that this is their pulse. Ask how they could measure the pumping of their hearts using the pulse. Students work in groups to brainstorm the possibilities. Allow groups to share and clarify. Have students feel for pulse with their fingers. |
Conclusion
Congratulations! You have now a knowledge about the circulatory System.Many of us don't know how complex the workings of our body are and yet we walk around in it every day of our lives. The body is amazing and today you started to look at just why it is so amazing. In your inquiry you are going to look at the different systems of the body and how they work perfectly together to help you exist and operate. You started looking at the Circulatory System.You learned about how much blood you have in your body and how fast the heart pumps it around the body.
