Oxytocin is released by posterior pitutory.It is produced by hypothalamus.
The target organ of hepatitis B virus (HBV) is the liver.
Since DNA is present in the nucleus of all cells, it is actually present in all organs.
The liver itself is not a target organ in the conventional sense, as it plays a central role in metabolism, detoxification, and various biochemical processes. However, it can be affected by various conditions that target liver cells, such as hepatitis or fatty liver disease. In this context, the liver can be considered a target organ for toxins, drugs, and certain diseases that impair its function. Overall, its health is vital for the proper functioning of many other organs and systems in the body.
parenchymal: essential, distinctive cells of an organ.
the hierarchy of cells from cells onward is :cells, tissues(this is the ensemble of cells), organ, organ system, organism.

The liverliver
The pituitary glad belongs to the endocrine system. The endocrine system contributes to the homeostasis, or balance, or the body by distributing hormones which regulate the activity and growth of target cells in the body.
Oxytocin causes the uterus to contract. Oxytocin is released by the posterior pituitary gland.
Once a hormone reaches it's target organ or cell, it increases or decreases the action in the organ or cell. This occurs with the metabolism of the hormones and cells.
spiral organ of Corti
An organ that contains receptor cells is called a sensory organ. These organs perceive external stimuli such as light, sound, touch, taste, and smell and transmit this information to the brain for processing.
Parietal cells in the stomach, which secrete HCl
The pituitary glad belongs to the endocrine system. The endocrine system contributes to the homeostasis, or balance, or the body by distributing hormones which regulate the activity and growth of target cells in the body.
Lymph nodes
The human body is composed of billions of cells. Each organ in the body is comprised of thousands of tissues, each of which are formed by thousands of cells.
uterus is the organ and reproductive/endocrine system cause the contraction (hormone-oxytocin is released in the body that causes the contractions to occur. If a woman is induced for labor pitocin is given which is the "man made" form of oxytocin
