Our nose is one of the few parts of our body that has a lot of nerves and blood vessels in it. It is often exposed to pollutants such as dirt and smoke. In response, the nose produces mucus to filter these pollutants before they reach the airways and the lungs. Aside from the mucus, the nasal passage also has tiny hairs (cilla) growing inside the lining of the passageway. […]
In every woman, there is a pair of gonads that lie nestled in their pelvic region. These are the ovaries, the makers of egg cells. Ovaries float so near the entrance to the falliopian tubes. Each time an egg cell matures, the surface of the ovary ruptures and releases the cell. It floats towards the tube and rolls towards the uterus. This process is called ovulation, which does not usually […]
Compared to the rest of our body, our scalp has the most number of hair strands growing on it.

Normally, touching our skin will not cause pain. There are cases, however, that a […]

These circumstances, however, are rare and the burning sensation on our tongue may pass harmlessly. When the […]

Blood is constantly moving inside the human body. It is distributed to all parts of the body so it can deliver oxygen to internal organs. This ability to move is due to the pressure exerted by the heart when pumping. The faster the heart pumps, the higher the blood pressure rises. Blood pressure is at its highest when the heart pumps the blood, which is what we call as heartbeat. […]

The right lung may be shorter, but it’s wider than the left. Why does our right lung have three lobes and is wider than the left lung? The answer is to make space for […]
