World of Biology on Instagram: "Ever wondered "How Rotational Atherectomy is done?" It’s a minimally invasive procedure where doctors use a tiny diamond-tipped burr that spins at high speed to grind away hardened plaque inside blocked coronary arteries. This restores smooth blood flow, especially in cases where stents cannot pass due to heavy calcification. The burr is guided through a catheter, controlled precisely, and the debris is safely washed away by blood flow. A stent is often placed aft

World of Biology on Instagram: "Blood circulation is the continuous flow of blood throughout the heart and blood vessels.

Driven by the heart’s pumping action, arteries transport oxygen-rich blood from the heart, while veins carry oxygen-poor blood back for reoxygenation. This vital system keeps your organs functioning, your brain alert, and your body energized around the clock. #biol

World of Biology on Instagram: "The evolution of the human heart! - We created this video showing the development of the human heart, starting from day 20, when the first primitive tube begins to beat. Over the following weeks, the heart loops, partitions, and rapidly grows more complex.

This visualization highlights each stage leading to the final structure showing the aorta,

World of Biology on Instagram: "Most IVF labs won’t consider injecting these fragile eggs, however I believe in giving patients every chance possible. This egg is missing its shell (zona pellucida). The shell normally protects the egg and keeps the cells together while the embryo replicates and divides. Without a shell, I wasn’t even sure if this is a mature egg. I wasn’t sure if it will survive the injection. Even if it does fertilize, the chances of it developing into an embryo is lower compar
