Answer:
The interaction between the nervous and cardiovascular systems is that the brain controls the functions of the heart and circulatory system through the autonomic nervous system and hormones, while the hearth and circulatory system provides blood with oxygen and nutrients to nervous system.
Explanation:
The nervous system (NS) is responsible for controlling and coordinating all organic activity in the body, including the function of the cardiovascular system (CVS). The interaction between the nervous and cardiovascular systems is due to their specific functions.
- <em>The </em><em>brain</em><em> is the main organ of the NS, receiving all the information from the internal environment and regulating the functions of the organs to maintain homeostasis. Although the activity of the heart is automatic, NS is in charge of </em><em>regulating the activity of this organ and the circulatory system, through the sympathetic and parasympathetic innervation</em><em> of the autonomic nervous system. Additionally, the brain can order the release of hormones, such as adrenaline, which influences cardiovascular activity.
</em>
- <em>CVS is in charge of conducting the blood to all the organs of the body. The relationship of this system with NS is clear: </em><em>providing blood with nutrients and oxygen to all its organs and tissues</em><em>, removing carbon dioxide and waste products from metabolic activity.
</em>
The interaction between NS and CVS is fundamental for the maintenance of life, and they are interdependent systems, since the functions of one allow the normal functioning of the other.
