How does an increase in the sympathetic nervous system affect stroke volume?
An increase in the sympathetic nervous system can lead to an increase in stroke volume. This is because the sympathetic nervous system stimulates the heart to beat faster and with more force, resulting in more blood being pumped out with each heartbeat.

Almost fifty percent of the volume of neural tissue in the central nervous system is made up of what?
Almost fifty percent of the volume of neural tissue in the central nervous system is made up of glial cells. Glial cells provide support and insulation to neurons, help maintain homeostasis, and play a role in immune response in the brain and spinal cord.

muscular, endocrine, nervous I believe... I do know that it's not circulatory, respiratory, nervous
Name three reasons why the nervous system is one of the most important system in the body?
First of all, the nervous system is like the central commanding centre of the body. Your breathing rate, homeostasis, your muscle movement - almost all systemic activities are regualted by the nervous system. When the nervous system gets disconnected from the rest of the body as in the case of a break in the spinal cord (for example), paralysis can occur. This is because the body as a whole needs instructions and these instructions have to be given by some organ/organ system. Take for example, a simple problem like dehydration. Your blood volume can decrease, which means your blood pressure can fall. When such an event occurs, hormones are secreted via a cascade to allow retention of more quantity of water from the kidney while filtration, allowing your blood volume to come back to some semblance of normalcy. So, each little environmental or internal event that can hamper the normal functioning of the body is counteracted by the decisions of the nervous system. Even muscular movement, especially involuntary, could not occur without the guidance of the nervous system. As such, the nervous system is the most important system in the body.
What accounts for 95 percent of volume of urine?
Water.
Is adh stimulated by another hormone the nervous system or humoral factors?
ADH (antidiuretic hormone) is primarily stimulated by humoral factors, such as changes in blood osmolality and blood volume. However, it can also be influenced by the nervous system, specifically through signals from the hypothalamus in response to stress or pain.
What planet has 1319 times volume to earth?
Jupiter. Its volume is roughly 1320 times that of Earth.
What is Key Accounts?
Key accounts also knows as major accounts, are the customers who buy high volume of the company's products or services that are profitable.
