Answer:

I) A decrease in vasomotor tone causes blood vessels to dilate and blood pressure to decrease.

II) Nervous control of blood vessels causes blood to be shunted from one large area of the body to another

III) In skeletal and cardiac muscle tissue, epinephrine and norepinephrine released by the sympathetic nervous system cause the blood vessels to dilate, increasing blood flow.

Explanation:

The Neurological regulation of blood pressure and flow depends on the cardiovascular centers located in the brain (medulla oblongata). This neurons in the brain tends to responds to changes in blood pressure as well as blood concentrations of oxygen, carbon dioxide, and other factors such as pH.

the cardiovascular center contains three distinct components: the cardioaccelerator center (stimulates cardiac function), the cardioinhibitor center (slows cardiac function), and the vasomotor center( which controls vessel tone or contraction of the smooth muscle in the tunica media).

The autonomic nervous system (ANS), plays a critical role in the regulation of vascular homeostasis. ANS comprised of two primary branches, sympathetic and parasympathetic nervous system,they both play an important role in the regulation of vascular wall contraction and tension which aid in the control of blood flow.

The statements that are correct about the nervous system control of blood flow include the following:

B. A decrease in vasomotor tone causes blood vessels to dilate and blood pressure to decrease.

C. Nervous control of blood vessels causes blood to be shunted from one large area of the body to another.

D. In skeletal and cardiac muscle tissue, epinephrine and norepinephrine released by the sympathetic nervous system cause the blood vessels to dilate, increasing blood flow.

A nervous system is a neural network that is made up of nerve cells and fibers, which are used for the transmission of neural impulses (signals) around the various body parts of a living organism.

Furthermore, the nervous system plays a significant role in controlling the transmission (flow) of blood around the various body parts of a living organism.

Hence, some of the ways the nervous system control blood flow in the body include:

  • Whenever there is a decrease in vasomotor tone, blood vessels become dilated and as such causing a decrease in blood pressure.
  • Blood are shunted from one large area of the body such as the stomach to another through the nervous system control of blood vessels.
  • The sympathetic nervous system secrete two hormones (epinephrine and norepinephrine) which cause the blood vessels to dilate, thereby, increasing blood flow in skeletal and cardiac muscle tissue.
