There are a pair of lungs in the thoracic cavity - the left lung and the right lung. The left lung is slightly smaller (because of the heart which is slightly to the left of the body) and has two lobes and the right lung is bigger with three lobes. They are spongy and elastic organs..

Closed Circulatory System in Humans - The closed circulatory system can be represented as follows. Diagram showing inter-relationship between artery, vein and capillary The closed blood vascular system is a very well developed system This is so because, a) The organisms have a thick ..
