Welcome to Mr PradMurthy

1. The best air filter in this world is human nose. Human nostrils are lined up with hair responsible for blocking germs and dust. Grooves in nasal cavity make air swirl like stream currents. This is when the inhaled hair is moistened and warmed so that the sensitive tissues of the lungs can be protected. It is during this filtration process that the mucus lining of the nasal cavity captures cold viruses and pollen which cannot be stopped by hair in nostrils.
2. Mucus is produced by human sinuses and nose and it contains white blood cells and enzymes responsible for fighting infections.
3. When someone inhales dry air, the air picks up moisture content from mucus. This makes the mucus pasty, which is known as snot or boogers.
4. Humans are capable of detecting 10,000+ scents. Humans can detect smell with special types of cells known as olfactory nerve cells. There are nearly 12 million olfactory cells present in a normal human. However, this number gradually decreases with age.
5. Olfactory nerves from nose have direct connection with brain. It is because of this that several types of smells can bring memories back.
6. Sense of smell is the only one of the 5 senses in humans which has direct connection with hippocampus – the part of the brain responsible for formation of memory.
7. Humans release pheromones – a type of chemical released only in response to sexual attraction. Nasal grooves in nostrils are sites rich in pheromones. Human nose is capable of detecting pheromones of opposite sex. According to experts, it is the pheromones in nose that led to the birth of smooching or romantic kissing.

1. Because air and food pass through, the throat is considered to be part of the respiratory system and digestive system.
2. Your throat is comprised of a variety of pharyngeal muscles and blood vessels.
3. Located at the back and sides of the mouth, your tonsils and adenoids are lymph nodes that help protect against infection. However, both generally serve little purpose beyond childhood.
4. The larynx houses the vocal cords and helps protect the trachea from food aspiration.
5. The larynx is crucial to breathing and having the ability to speak.
6. The epiglottis works with the larynx to prevent food from entering the windpipe. Instead, together both push food into the esophagus.
7. Located in your throat, the hyoid bone is the only bone in the human body that is not attached to any other.
8. The hyoid bone is only found in Neanderthals and humans.
9. The hyoid bone is considered to be the “foundation of speech” for humans.
10. Parts of the trachea and esophagus that are located beneath the breastbone are not deemed to be parts of the throat.
11. Your throat branches off into two at the bottom. On branch takes air to your lungs, while the other branch takes food to your stomach. .

1. Sinusitis may be acute or chronic.
2. A cold or allergy attack that won’t go away may actually be sinusitis.
3. Irritating environmental pollutants may precipitate a sinus infection.
4. Bacteria can cause an acute bacterial sinus infection.
5. Antibiotics are often effective in treating acute sinusitis.
6. Recurrent or untreated acute sinusitis can lead to chronic sinusitis.
7. Frequent bouts of sinusitis or sinus infections that last three months or more may be chronic sinusitis.
8. Symptoms of chronic sinusitis are facial pain or fullness, nose congestion, persistent inability to smell, post-nasal discharge and headache.
9. Chronic sinusitis is a mechanical problem. Relief of obstruction requires long-term therapy with prescribed oral and/or nasal medication.
10. Endoscopic sinus surgery may also relieve obstruction.

1. The thyroid gland is located in the middle of the lower neck.
2. Although the thyroid gland is relatively small, it produces a hormone that influences every cell, tissue and organ in the body.
3. Hypothyroidism is a condition where the thyroid gland does not produce enough thyroid hormone. Symptoms include extreme fatigue, depression, forgetfulness, and some weight gain.
4. Hyperthyroidism, another form of thyroid disease, is a condition causing the gland to produce too much thyroid hormone. Symptoms include irritability, nervousness, muscle weakness, unexplained weight loss, sleep disturbances, vision problems and eye irritation.
5. Graves’ disease is a type of hyperthyroidism; it is an autoimmune disorder that is genetic and estimated to affect one percent of the population.
6. Up to 60 percent of those with thyroid disease are unaware of their condition.
7. Women are five to eight times more likely than men to have thyroid problems.
8. One woman in eight will develop a thyroid disorder during her lifetime.
9. Most thyroid cancers respond to treatment, although a small percentage can be very aggressive.
10. The causes of thyroid problems are largely unknown.
11. Undiagnosed thyroid disease may put patients at risk for certain serious conditions, such as cardiovascular diseases, osteoporosis and infertility.
12. Pregnant women with undiagnosed or inadequately treated hypothyroidism have an increased risk of miscarriage, preterm delivery, and severe developmental problems in their children.
13. Most thyroid diseases are life-long conditions that can be managed with medical attention.
