Question
There are two similar glands P which are located on top of two similar organs Q in the human body. P are often called the emergency glands and they secrete a hormone R into the blood stream. R is secreted in large amounts when a person is frightened. It brings about temporary changes in the body which allow a lot of substance S from the liver to go into the blood to provide a lot of energy in a very short time. This helps a person to fight back or run away from the frightening situation.
What are P, Q, R and S?

Solution
P is adrenal glands.
Q is kidneys.
R is adrenaline hormone.
S is glucose.
Humans have two adrenal glands, which are located on top of the kidneys. They are often called emergency glands. They secrete adrenaline into the bloodstream. It is secreted in large amounts when a person is frightened.
Adrenal gland brings about temporary changes in the body which allow glucose from the liver to go into the bloodstream. This provides a lot of energy in a very short time.
