What happens during Heart Attack | Symptoms Precautions | Heart attack

Approximately 7 million people around the world die from heart attacks every year, and cardiovascular disease, which causes heart attacks and other problems like strokes, is the world's leading killer. So what causes a heart attack? Source: Internet Like all muscles, the heart needs oxygen, and during a heart attack, it can't get enough. Fatty deposits, or plaques , develop on the walls of our coronary arteries. Those are the vessels that supply oxygenated blood to the heart. These plaques grow as we age, sometimes getting chunky, hardened, or enflamed. Eventually, the plaques can turn into blockages. If one of the plaques ruptures or cracks, a blood clot will form around it in minutes, and a partially closed artery can become completely blocked. Blood flow is cut off to the cardiac muscle and the oxygen-starved cells start to die within several minutes. This is a myocardial infarction , or heart attack . Things can rapidly deteriorate in the absence of ...

Earthquake | Why earthquake happens | Why are earthquakes so hard to predict? | TCS - The CBSE Solver

Early Story:- In 132 CE, Chinese polymath Zhang Heng presented the Han court with his latest invention. This large vase, he claimed, could tell them whenever an earthquake occurred in their kingdom– including the direction they should send aid. The court was somewhat skeptical, especially when the device triggered on a seemingly quiet afternoon. But when messengers came for help days later, their doubts turned to gratitude. Today, we no longer rely on pots to identify seismic events, but earthquakes still offer a unique challenge to those trying to track them. So why are earthquakes so hard to anticipate, and how could we get better at predicting them? Earth’s structure: To answer that, we need to understand some theories behind how earthquakes occur. Earth’s crust is made from several vast, jagged slabs of rock called tectonic plates , each riding on a hot, partially molten layer of Earth’s mantle . This causes the plates to spread very slowly, at anywhere from ...
