  HEART , the mesodermally derived organ, is situated in the thoracic cavity, in between the two lungs, slightly tilted to the left. It has the size of a clenched fist. It is protected by a double walled membranous bag, pericardium, enclosing the pericardial fluid. Our heart has four chambers, two relatively small upper chambers called atria and two larger lower chambers called ventricles. A thin, muscular wall called the inter- atrial septum separates the right and the left atria, whereas a thick-walled, the inter-ventricular septum, separates the left and the right ventricle The atrium and the ventricle of the same side are also separated by a thick fibrous tissue called the atrio-ventricular septum. However, each of these septa are provided with an opening through which the two chambers of the same side are connected. The opening between the right atrium and the right ventricle is guarded by a valve formed of three muscular flaps or cusps, the tricuspid valve, whereas

  Recently, Waqar Younis also gave his take on the issue. Speaking on   A Sports ,  he criticised the Langer’s praise for Warner in this matter. The Australia coach had earlier said: “Oh my gosh, it’s one of the best things I’ve ever seen in the game of cricket,” Langer had said while talking about Warner’s six. I can’t believe anyone would have the instincts to do that — it was unbelievable. In fact, most people probably would’ve been not sure what to do … it was a no-ball, and to have the talent and ability to hit it for six — unbelievable.” “It’s fine, It is legal. He was within his right to hit it, and he went for it that’s all good. But to promote it is wrong. The way it’s being praised by Justin Langer, that is ridiculous. What are you teaching the little kids? You can do the same if that’s your mindset, but don’t teach the youngsters that it’s fine to go for it if you get the opportunity.” <script async src="https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js?
