The sympathetic portion of the autonomic system is activated. You activate what is called the Fight or Flight system. Your heart beat increases as well as your blood pressure.
Sympathetic stimulation of the eye will cause dilation of the pupil (mydriasis) and relaxation of the ciliary muscle for far vision.
Sympathetic stimulation causes vasoconstriction of most arterioles in the body, except for arterioles in skeletal muscle and the heart where it causes vasodilation.
Sympathetic stimulation results in renin secretion by the kidneys and causes a relaxation of the bladder. Accompanied by a constriction of the bladder sphincter, sympathetic stimulation tends to decrease urination and promote fluid retention.
Yes, coronary vessels have both parasympathetic and sympathetic innervation. Parasympathetic input leads to vasodilation of coronary vessels, while sympathetic input can cause vasoconstriction in response to stress or exercise. The balance between these two systems helps regulate blood flow to the heart.
Sympathetic postganglionic fibers end in effector organs such as smooth muscles, cardiac muscles, and glands. They innervate these structures to modulate their activity in response to stress or stimulation of the sympathetic nervous system.
Sympathetic stimulation of the eye will cause dilation of the pupil (mydriasis) and relaxation of the ciliary muscle for far vision.

Bronchodilation.

yes
Sympathetic stimulation (I'm guessing you mean your bodie's reaction in fight or flight) makes the blood vessles tighten, or constrict, hightening blood pressure. This is bad for you over long periods of time.
Sympathetic stimulations are signals to the body that imply stress. Sympathetic stimulation stimulates the sympathetic part of the peripheral nervous system and results in multiple response such as increased cardiac output, dilation of the pupil, inhibition of the smooth muscles of the gastrointestinal tract and urinary bladder, and erection of the penis.
increase its rate and force of contraction
with stimulation of the sympathetic nervous system there will be a. constriction of the pupils b. dilation of the coronary arteries c. constriction of selected blood vessels d. profuse sweating

false
Sympathetic stimulation causes relaxation of the rectum's smooth muscle, leading to decreased motility and tone. This can result in decreased urgency and the ability to retain feces.
