12) ALVEOLI: In the lungs, clusters of 9ny, thin-­‐
walled air sacs at the end of each bronchiole, where oxygen and carbon dioxide are exchanged. ARTERY A thick, elas2c-­‐walled vessel that moves 13a) ___________: blood away form the heart. VEIN 13b) ___________: a blood vessel with one-­‐way valves that moves blood toward the heart, carrying wastes (including CO2) 14): CAPILLARY a microscopic blood vessel that connects arteries and veins; nutrients, oxygen, and wastes are exchanged through their one-­‐cell-­‐thick walls. 17) PULMONARY CIRCULATION: The path of blood from the heart, to the lungs, and back to the heart. 19) SYSTEMIC CIRCULATION: The flow of blood from the heart to all the body 2ssues (except lungs and heart) and back to the heart.

Carbon dioxide is released during cellular respira2on EQ: What is the purpose of the Respiratory System and what are the func9ons of the organs that are involved? II) Respiratory System A) Func2ons of the respiratory system: 1) Breathing – movement of the chest to bring air into the lungs and remove waste gasses 2) Cellular respira2on – the oxida2on of food (e.g. glucose/sugar) to release energy and store energy in ATP molecules 3 or more a) Reactants ! Products; Ques2ons Sugar + Oxygen ! Carbon Dioxide + Water + Energy B) Organs of the respiratory system 1) The pharynx – tubelike passageway used for food, liquid and air; 2) Air passes through the larynx, which contains the vocal cords used to speak. 3) Trachea – tube held open by rings of car2lage; lined with cilia and mucous membranes a) There is a flaplike 2ssue called the epiglods that blocks food from entering the trachea 4) At the lower end of trachea, two short tubes called bronchi branch into smaller tubes 5) Smallest tubes are bronchioles, which end in clusters of alveoli. 6) The alveoli are surrounded by capillaries. This is where oxygen enters the blood and waste products exit the blood. Compare human circulatory and highway systems – both move goods and remove wastes. Pulmonary circula9on moves blood between the heart and lungs. The caro9d artery moves oxygenated blood from the heart to the brain. Capillaries are microscopic blood vessels 1 2 3 1) In your body, a __ system distributes materials. Cardio-­‐ means __ and vascular means __. 2) What does your cardiovascular system consist of? 3) What is diffusion? (Movement of materials in and out of your cells happens by diffusion.) 1) Cardiovascular, heart, vessel. 2) The cardiovascular system includes your heart, blood, and kilometers of vessels that carry blood to every part of your body. 3) Diffusion is when a material moves from a place of high concentra9on to an area of lower concentra9on.
