دعونا ننظر داخل القلب؟
في هذه الرحلة الافتراضية عبر القلب، نرى الصمام التاجي (الصمام التاجي)، والخيوط الوترية، والعضلات الحليمية ، والصمام الأبهري (شبه القمري).
يمكنك أيضًا ملاحظة جيوب فالسالفا - فهي تقع خلف الجيوب الأبهري، خلف الصمامات الهلالية مباشرة، والتي يبدأ منها سرير الشرايين التاجية اليمنى واليسرى (إمداد الدم إلى القلب).

The S&P 500 slumped 1.8% on Monday and Tuesday, thanks to China Evergrande, the Chinese property company that looks like it is ready to default on its more-than $300 billion in debt. Cries of the next Lehman Brothers—or maybe the next Silverado?—echoed through the canyons of Wall Street as investors prepared for the worst.
The SSE was the first modern stock exchange to open in China, with trading commencing in 1990. It has now grown to become the largest stock exchange in Asia and the third-largest in the world by market capitalization, which stood at RMB 50.6 trillion (US$7.8 trillion) as of September 2021. Stocks (both A-shares and B-shares), bonds, funds, and derivatives are traded on the exchange. The SEE has two trading boards, the Main Board and the Science and Technology Innovation Board, the latter more commonly known as the STAR Market. The Main Board mainly hosts large, well-established Chinese companies and lists both A-shares and B-shares.
