Investigation 3, Part 2 Circulatory System Model Materials: the left and right ventricles of the heart used to help secure hoses blood in body blood in lungs 4 heart valves veins and arteries the "left ventricle" and "right ventricle" bottles and "lung blood“ • Label and "body blood" containers using the self-stick notes. veins and arteries • Fill all four containers halfway with water. insert securely in the ends of the rigid pipes. Flexible hoses Time • Valves fit over the ends of the pipes. IG pg. 233– 234, Steps 12– 13

Investigation 3, Part 2 Vocabulary Review circulatory system the system of blood vessels and organs that transports blood to all the cells in the body artery a blood vessel that carries blood from the heart to the body vein a blood vessel that carries blood from the body to the heart capillary the smallest blood vessel. Gases, nutrients, and wastes are exchanged between capillaries and cells. heart a muscular organ that pumps blood IG pg. 235, Step 15

Investigation 3, Part 2 Vocabulary Review right atrium the upper chamber on the right side of the heart right ventricle the lower chamber on the right side of the heart lung the organ in animals where gases, such as oxygen and carbon dioxide, pass between the atmosphere and the blood left atrium the upper chamber on the left side of the heart left ventricle the lower chamber on the left side of the heart valve a structure in the heart that acts like a one-way gate, ensuring that blood flows in one direction through the circulatory system IG pg. 235, Step 15
