उत्तर
Wearing a helmet helps to protect your life and protect your head from danger. The head and brain are the most vulnerable to injury in a motorcycle accident. Drivers and passengers wearing helmets increase their chances of survival over non-helmet wearers. Riders who do not wear helmets are at risk of suffering a traumatic brain injury if they are in an accident. Brain trauma often results in spinal cord injuries and disability that requires extended care and physical therapy. The damaged brain may deteriorate after hospitalization and die days to weeks after the injury due to secondary injury.

| Bile juice is stored in a sac called, gall bladder, located near its organ of secretion, liver. The gall bladder releases the bile juice into the small intestine whenever food reaches there. Though bile juice is devoid of any digestive enzymes, it is required for the digestion of fats. The fats cannot be digested easily because they are insoluble in water and are present as large globules. Bile juice breaks down big fat droplets into smaller droplets. These are then easily digested by the enzymes released from the pancreas. |
