Once the genes in an endocrine organ have been transcribed to RNA and then the RNA has been translated, the new hormones are then secreted from the cell into
Once the genes in an endocrine organ have been transcribed to RNA and then the RNA has been translated, the new hormones are then secreted from the cell into the bloodstream, where they can then travel to target cells and tissues to carry out their functions.
What informs the secretion of hormones?The secretion of hormones is controlled by various mechanisms, including the action of other hormones, changes in blood levels of ions and nutrients, and nervous system signals.
Hormones play a critical role in regulating various physiological processes, such as growth and development, metabolism, and reproduction. The secretion of hormones from endocrine cells into the bloodstream is a tightly regulated process that ensures that the right amount of hormone is released at the right time, allowing the hormone to effectively regulate its target cells and tissues.
Once the hormone reaches its target cells, it can bind to specific receptors on the cell membrane, triggering a series of events that lead to the desired physiological response. The responsiveness of target cells to a particular hormone can also be regulated by various factors, including the number of receptors present on the cell surface, the affinity of the receptor for the hormone, and the ability of the target cell to respond to the hormone.

correctly order the following components, from the smallest to the largest.
organ system
cell
organ
tissue
Answer:
Cells → Tissues → Organs → Organ Systems.
Explanation:
The human body is made of trillions of cells. Cells are the basic unit of life. There are many different types of cells in the human body that have varying structures and serve different, specific functions.
These cells are organized into tissues. A tissue is a group of cells that work together to serve a specific function. A tissue’s function is determined by the types of cells it is made of.
Several types of tissue work together as an organ. Different organs in the body carry out different functions. For example, the heart pumps blood throughout the body, the stomach breaks down food, and the brain controls and coordinates the activities of the body.
A group of organs will work together in organ systems that perform our life functions. For example, the stomach and small intestine work together within the digestive system to break down food and then absorb the nutrients, releasing them into the bloodstream. The heart and blood vessels work together in the circulatory system to move the blood and the nutrients it carries around the body.
Therefore, we can conclude that the order of these structures, from smallest to largest, is cells → tissues → organs → organ systems.
