Photosynthesis and cellular respiration are related in that; photosynthesis is a process that is tasked in making glucose which is then used in cellular respiration to make ATP. The glucose is then converted to carbon dioxide during cellular respiration, which is used in photosynthesis. Water on the other hand is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
In respiratory system the lungs are two spongy, cone shaped organs in the thoracic cavity and are separated from each other by the heart and other structures found in the mediastinum.
Deep grooves called fissures divide each lung into lobes. Each lobe receives its own secondary bronchus. Each lung lobe is divided into smaller segments that are supplied by a tertiary bronchus.
<em><u>The segments, in turn are subdivided into small compartments called lobules, which contains, lymphatic vessel, arteriole, venules and also a branch from terminal bronchiole wrapped in elastic connective tissue.</u></em>
