Know Your Body: ANSWERS

  1. B.Red Blood Cells — Red blood cells are the chief carriers of oxygen in the body. White blood cells play an important role in fighting infections. Epidermal cells are found in the top layer of the skin.
  2. A.Retina — You are able to see things because a highly specialized tissue in your eye called the retina forms an image of the object and transmits the information to your brain. Diaphragm is a large muscular structure separating your chest from your abdomen. Tympanum or the ear drum helps in hearing.
  3. C.Larynx — The larynx or the voice box is made of several cartilages and folds whose vibration produces voice. The pharynx is the upper broad structure between the mouth and food pipe. Trachea or wind pipe is the tube that carries oxygen to the lungs.
  4. C.Pancreas — Insulin is produced by the Pancreas. It also produces a lot of enzymes that help in digestion. Pituitary or the master gland is located at the base of your brain. It produces many hormones that regulate the production of other hormones. The thyroid gland is located in your neck. Thyroid hormones have important role in growth and metabolism.
  5. A.SA Node — It’s a small structure that works as the hearts’ primary pacemaker. If the SA node fails, the heart has a backup in the form of AV node. Left ventricle is a hollow chamber from which blood is eventually pumped out of the heart. Valves in the heart, including the mitral valve prevent backward flow of blood within the heart.
