The figure shows some of the main
endocrine glands in the body. Which endocrine organ (A), (B),
(C), (D), or (E) secretes growth hormone? Which endocrine organ (A), (B),
(C), (D), or (E) controls blood sugar levels?
To answer this question, we need to
be able to identify some of the endocrine glands that are shown in this image, the
hormones they release, and the functions of these hormones. So let’s get started. Organ (A) is the pituitary gland,
located at the base of the brain. The pituitary gland is sometimes
called the master gland as it releases hormones that can have an effect on many of
the other endocrine glands. One of the hormones it releases is
called growth hormone. The main function of growth hormone
is to control tissue growth and cell regeneration. Therefore it’s a really important
hormone in human development. So we’ve worked out the answer to
the first part of the question. Which endocrine organs secrete
growth hormone? It’s organ (A), the pituitary
gland.
Let’s have a go at the second part
of the question now. The organ labeled as (D) is called
the pancreas. The pancreas also releases several
hormones, one of which is called insulin. Insulin is partly responsible for
maintaining blood sugar level within a healthy range. In fact, if blood sugar levels
become too high, insulin functions to lower blood sugar levels back to a normal
level. So we’ve worked out the second part
of the question that the endocrine organ that controls blood sugar levels is (D),
the pancreas.
