1. DO NOW: 1. Draw a flow chart showing how blood travels from the body systems to the lungs (start at vena cava & end at vena cava). Include the four chambers of the heart, and as many blood vessels as you know. Do this without your notes--see how much you remember! 2. What are the components of blood? Respiration Vocabulary: lungs, trachea, bronchi, bronchioles, pharynx, larynx, alveoli, diaphragm, epiglottis Hand in New York Times Article Summary HW due tomorrow as it is on the syllabus pg 955 and 963 HW due Thursday pg 967 ques 1-10 and 19-22 Results and Discussion section due via turnitin.com on 12/23 Aim: What are the structures and functions of the respiratory system?

2. What are the functions of each structure in the heart?

3. Superior and Inferior Vena Cava Right Atrium Lungs Pulmonary Vein Right Ventricle Left Atrium Pulmonary Artery Left Ventricle Aorta END To the Body START Activity: Work with a partner to complete the flow chart. Use the table of structures to help you. What structures present carry oxygenated blood? Which carry deoxygenated blood? HOW IS BLOOD PUMPED THROUGH THE HEART?

7. Questions for Review Answer the following questions in your notebooks. You may work with a partner. List the structures of the circulatory system. Compare the functions of the three types of blood vessels in the circulatory system. Describe the path of blood circulation through the body. List in order the structures of the respiratory system through which air passes from the outside of the alveoli. Explain the process of gas exchange in the lungs. Describe how breathing is controlled.
