Answer: Hypothalamus
The brain coordinates the physical changes that occur during puberty and the hypothalamus plays an especially important role in this process.
Explanation:
Since the hypothalamus controls the secretion of hormones from the pituitary gland, and the pituitary gland, also known as master gland, controls the activities of all other glands like the following:
- gonads (ovaries and testes), responsible for producing many of the sex hormones and hence, development of sexual characterictics
- thyroid, responsible for producing thyroxine, responsible for body metabolism and development.
Thus, hypothalamus plays important role in puberty
Transport of blood under high pressure is done through the concerted efforts of the heart and arteries.
<h2>The circulatory system is the network of the heart, arteries, veins, and capillaries responsible for the movement of blood around the body.</h2>
Transporting blood under high pressure can be explained in the following steps:
- Contraction of the heart ventricles creates blood under high pressure
- High pressured blood is removed from the heart through the arteries. In addition, the arteries are able to contract and expand, thus are elastic
- The lumen of the arteries is narrow thus helping in maintaining high pressure
As a result of the above, the high pressure of blood is maintained and transported to the extremities of the body.
