Question

write the effects of sympathetic and parasympathetic of the following organs
I, heart, gastric secretion,bronchi​

Answer 1

Effects of sympathetic and parasympathetic of the following organs:

HEART

• Sympathetic nervous system increase the frequency of action potential thus increasing the heart rate whereas antagonistically

• parasympathetic nervous system decrease the frequency of action potential thus lowering the heart beat. Both of them act antagonistically to control the heart beat.

GASTRIC SECRETIONS

• Sympathetic stimulation causes inhibition of gastrointestinal secretion and motor activity, and contraction of gastrointestinal sphincters and blood vessels.

• Conversely, parasympathetic stimuli typically stimulate these digestive activities

BRONCHI

• The bronchioles in the lung are dilated by sympathetic nervous system to allow more air into the lungs, which will increase oxygenation of the blood and keep up with the increased flow of blood through the lungs due to the increased heart rate.

• These are constricted by parasympathetic nervous system.
