Hello Students, Here we are provided Labelled diagram of Schematic representation of transport and exchange of oxygen and carbon dioxide with pencil in a simple way. Drawing of Schematic representation of transport and exchange of oxygen and carbon dioxide can be huge struggle for beginners. CBSE / ICSE students who are always avoid drawing, this post is just for you!
Students of Class 6, Class 7, Class 8, Class 9 & Class 10 CBSE / ICSE board Students can follow this post. Here we have also added a Video by our Teacher, in where our Mam has indicated each Part as well as function of each part.
The schematic representation of transport and exchange of oxygen and carbon dioxide contains the pulmonary artery, lung capillaries, pulmonary veins, vena cava, aorta, artery and veins for the exchange of oxygen.
Oxygen-rich blood from the lungs enters the thin-walled upper chamber of the heart, the left atrium. It relaxes the left atrium while collecting blood. It then contracts, while the next chamber, the left ventricle relaxes allowing blood to transfer into it. Blood is ejected into the body when the muscular left ventricle contracts. Deoxygenated blood flows from the body to the right, upper chamber of the right atrium, as it relaxes. As the right atrium contracts the respective lower chamber of the right ventricle dilates. It transfers blood to the right ventricle, which pumps it to the lungs for oxygenation. Because the ventricles have to pump blood to various organs, their muscular walls are thicker than the atria. Valves ensure that blood does not flow backwards when the atria or ventricles contract. It is helpful to separate the right side and left side of the heart to prevent mixing of oxygenated and deoxygenated blood. Such separation allows for a highly efficient supply of oxygen to the body
