When you are suddenly frightened, the sympathetic nervous system is activated, triggering the "fight or flight" response. This system rapidly prepares the body for quick action by increasing heart rate, dilating airways, and redirecting blood flow to muscles, enhancing physical performance. Hormones like adrenaline are released, further boosting energy and alertness, allowing for a swift escape from danger.

The sympathetic division of the autonomic nervous system is MOST likely to be activated when you are?

The sympathetic division of the autonomic nervous system is most likely to be activated during "fight or flight" situations when the body needs to respond quickly to a perceived threat or stressor. This can lead to a variety of physiological responses such as increased heart rate, dilated pupils, and the release of adrenaline to prepare the body for action.


What is a group of more than 20 plasma proteins that circulate in the blood until activated?

A group of more than 20 plasma proteins that circulate in the blood until activated is known as the complement system. This system plays a crucial role in the immune response, helping to enhance the ability of antibodies and phagocytic cells to clear pathogens from an organism. When activated, these proteins work together in a cascade to promote inflammation, opsonization, and the lysis of pathogens. The complement system is essential for both innate and adaptive immunity.


What division prepares the body to respond to a threat?

The division of the autonomic nervous system that prepares the body to respond to a threat is the sympathetic nervous system. When activated, it triggers the "fight or flight" response, increasing heart rate, dilating airways, and redirecting blood flow to essential muscles. This physiological response enhances the body's ability to react quickly to danger.
