Adrenaline targets various organs,mainly - the Heart, Blood vessels, Smooth muscles(of bronchi, uterus, gastrointestinal tract,bladder etc.), the eye (radial muscles of iris), skeletal muscles (central nervous system also, but weak effect is seen there), metabolic actions (via liver)
It acts via various alpha and beta receptors present at these target organs.
Its main actions can be simplified as below:
Heart-via beta 1 receptors-Adrenaline increases the Heart rate, force of contraction, cardiac output and conduction velocity
Blood vessels-via alpha and beta2 receptors causes constriction mainly in vessels of skin, kidneys and dilatation in vessels of skeletal muscles, liver.
Bronchial smooth muscles - via beta2 receptors- causes broncho dilatation.
Blood pressure- overall rise in blood pressure
Eye- via alpha1 receptors- contraction of radial muscles if iris,therefore increases size of pupil (mydriasis)
CNS- restlessness, apprehension, tremors
Metabolic action- rise in blood glucose levels, lactic acid level, free fatty acid levels.

What is a target organ?
A target organ is an organ that is targeted by a drug or hormone. These drugs usually stimulate the organ to produce its own hormones or react positively and function in response to the drug, such as adrenaline to the heart.

Body cells that react to particular hormone are called?

What is the Ganglia called in or near target organ?
The ganglia in or near the target organ are called intramural ganglia. These ganglia are part of the autonomic nervous system and are responsible for regulating local functions within the target organ.
What best describes a target organ?
the target organ is the part of the body that is most adversely affected by exposure to a hazardous substance
Which cells does the hormone adrenaline specifically target and affect?
Adrenaline specifically targets and affects cells with adrenergic receptors, such as those in the heart, lungs, and blood vessels.
What is the target organ for progesterone?
The target organ for progesterone is the ovary and the embryo
Is adrenaline an active transport or an passive transport?
Actually adrenaline is a hormone that is secreted directly from the pancreas into the blood stream to the target organ, the liver and since there is no selectively permeable membrane it must be passive transport (diffusion).
