. 8 grams of protein for every kilogram of weight. Delivers oxygen to our blood and returns carbon dioxide back to the air. Works with the cardiovascular system to deliver oxygen throughout the body. Strong helps to move the lungs to bring in oxygen and expel carbon dioxide. Age related changes to the respiratory system. Decreases ability to warm and humidify air. Decreases rate of airflow to the lungs. This happens because trachea flattens in your sleep and you stop breathing. Alveoli lose shape and walls may become damaged. Limits the exchange of oxygen and carbon dioxide between the blood and lungs. Decrease ability to breathe in and out. Bones become brittle which can constrict the lungs. See how hard/the amount you can exhale and inhale. Left side: pumps blood to the rest of the body. Age related changes to the cardiovascular system. Thickening of the walls and valves of the heart.
