Adrenaline specifically targets and affects cells with adrenergic receptors, such as those in the heart, lungs, and blood vessels.
receptors on their surface that specifically bind to the hormone, triggering a signaling cascade within the cell. This cascade leads to specific cellular responses and effects in response to the hormone's presence.
The target receptor proteins of cells will cause them to affected by a specific protein. These cells are also called "target" cells. Hormones flow via the bloodstream throughout the entire body, but they only affect their specific "target" cells.
Hormones affect target cells because target cells have receptors that bind with certain hormones (they're specific). If a cell does not have a receptor then it is not affected by hormones. Target cells (which do have the receptor for a particular hormone) would be affected by the hormone.
Because they only activate target cells that have special receptors that only work when that specific hormone attaches to it.
Target cells are cells that have specific receptors for a hormone or external signal, allowing them to respond to the signal. Non-target cells do not have receptors for the hormone or signal, so they do not respond to it. Target cells are the primary sites of action for hormones, while non-target cells are unaffected by the hormone.
An example of a chemical messenger is a hormone, such as insulin or adrenaline, which is produced by glands in the body and travels through the bloodstream to target cells to regulate various physiological processes.
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.
the target organ for adrenaline is the epiglodis found in the mouth
Adrenaline is a hormone. Hormones are chemicals which travel via the blood stream to reach their targets. A hormone may have one or more than one targets. Since they are carried by the blood, the response (in this case the increased heart rate) is initiated when the blood carrying the hormone gets to the target cells, hence the delay.
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).

ACTH means adrenocorticotrophic hormone. The target for this hormone is adrenal gland. It stimulate the gland to produce the corticosteroid hormone.
Hormone receptor
The previous answer was wrong, adrenaline does not travel in the blood stream as it is an excepion to the usual hormones secreted from the endocrine system.
The main primary target tissue of the Parathyroid hormone is the bone, but the kidneys are a target as well.
