Thus, there remains lingering doubt about the mechanisms of ethanol listed here, even for the GABA A receptor, the most-studied mechanism. [24] In the past, alcohol was believed to be a non-specific pharmacological agent affecting many neurotransmitter systems in the brain, [25] but progress has been made over the last few decades.
Bone tissue is a dynamic system with active metabolism. [24] Bone tissue remodelling or bone remodeling is a successive chain of old bone matrix removal and its replacement with a new one. [25] These processes make a child’s skeleton grow and extend, while childhood is characterized by bone tissue growth rather than its resorption.
The human digestive system consists of the gastrointestinal tract plus the accessory organs of digestion (the tongue, salivary glands, pancreas, liver, and gallbladder). Digestion involves the breakdown of food into smaller and smaller components, until they can be absorbed and assimilated into the body.
Alcohol levels within the body are usually detected through blood or breath. The best way to identify endogenous ethanol in the bloodstream is through gas chromatography. In gas chromatography the breath or blood is heated so that the different components of the vapor or blood separate. The volatile compounds then pass through a chromatograph ...
Direct alcohol tolerance is largely dependent on body size. Large-bodied people will require more alcohol to reach insobriety than lightly built people. [4] The alcohol tolerance is also connected with activity of alcohol dehydrogenases (a group of enzymes responsible for the breakdown of alcohol) in the liver, and in the bloodstream.
In others, once potential nutrients or food is inside the organism, digestion can be conducted to a vesicle or a sac-like structure, through a tube, or through several specialized organs aimed at making the absorption of nutrients more efficient.

Extracting bone marrow from larger bones is easier than smaller bones. [14] Forensic toxicologists often use bone marrow to find what type poisons used, which can include cocaine or ethanol. [15] Ethanol specifically is one of the most abused drugs worldwide, be it through alcohol consumption and abuse being a leading cause in death.
Control of the digestive system is also maintained by ENS, which can be thought of as a digestive brain that can help to regulate motility, secretion and growth. Sensory information from the digestive system can be received, integrated and acted upon by the enteric system alone. When this occurs, the reflex is called a short reflex. [4]
