An example of adrenaline action in the nervous system is increased alertness and improved focus during a fight-or-flight response. Adrenaline activates the sympathetic nervous system, leading to enhanced sensory perception and rapid decision-making to help the body respond to a perceived threat.
adrenaline
A response to adapt to a situation...for example fear could create an adaptive response to "fight or flee", or could paralyze the person into inaction.
In biology, an effector is an organ that reacts to the external stimuli on receiving signals from the central nervous system. An example is when the adrenal gland secretes adrenaline in response to stress or danger.
An example of a nonspecific internal response to harmful bacteria is inflammation. Inflammation is a general response triggered by the immune system to protect the body from foreign invaders. It involves increasing blood flow to the area, causing redness, swelling, and pain.
Inotropic agents example are positive inotrops- digoxin, adrenaline, nor adrenaline,dopamine,dobutamine, amrinone, etc.
An example of alarm reaction is the body's immediate "fight or flight" response when faced with a threat or stressor. This can include increased heart rate, heightened senses, and the release of stress hormones like adrenaline to help the body prepare to respond to the perceived danger.
An example of an external stimulus for a plant is light, which influences growth direction through phototropism, causing plants to bend toward the light source. An internal stimulus could be the plant's hormonal response to stress, such as the production of abscisic acid in response to drought, which triggers stomatal closure to conserve water. Both types of stimuli play crucial roles in a plant's survival and adaptation.
An example of a non-antagonistic interaction of the sympathetic nervous system is when it triggers the "fight or flight" response in response to a perceived threat. This response involves simultaneous activation of multiple physiological processes such as increased heart rate, dilated pupils, and release of adrenaline to help the individual respond to the threat effectively.
Plants respond to stimuli through growth movements. For example, phototropism is their response to light, causing them to grow towards it. Thigmotropism is their response to touch, triggering growth in response to physical contact. These responses help plants adapt and survive in their environment.

The endocrine system can affect the respiratory system. Example: Adrenaline or endorphins produced by the endocrine system can cause the heart to beat faster then causing the body to breathe more heavily. Also the inability to breathe - caused by varying conditions- can cause the body's endocrine system to produce such adrenaline or negative panic hormones.
