The colon receives blood from both the superior and inferior mesenteric arteries. The blood supply from these two major arteries overlaps, with abundant collateral circulation via the marginal artery of the colon. However, there are weak points, or "watershed" areas, at the borders of the territory supplied by each of these arteries, such as ...
The level of ethanol consumption that minimizes the risk of disease, injury, and death is subject to some controversy. [16] Several studies have found a J-shaped relationship between alcohol consumption and health, [17] [18] [2] [19] meaning that risk is minimized at a certain (non-zero) consumption level, and drinking below or above this level increases risk, with the risk level of drinking a ...
Alcohol use disorder (AUD) is defined as a medical condition characterized by an impaired ability to stop or control alcohol use despite adverse social, occupational, or health consequences. [123] Excessive alcohol use can lead to health-related illness and continuous alcohol engagement can ultimately lead to death.
These organisms use lactic acid fermentation or mixed acid fermentation pathways to produce an ethanol end product. [3] The ethanol generated from these pathways is absorbed in the small intestine, causing an increase in blood alcohol concentrations that produce the effects of intoxication without the consumption of alcohol.

Alcohol use is a major contributing factor for head injuries, motor vehicle injuries (27%), interpersonal violence (18%), suicides (18%), and epilepsy (13%). [197] Beyond the financial costs that alcohol consumption imposes, there are also significant social costs to both the alcoholic and their family and friends. [67]
Risk factors known as of 2010 are: Quantity of alcohol taken: Consumption of 60–80 g per day (14 g is considered one standard drink in the US, e.g. 1 + 1 ⁄ 2 US fl oz or 44 mL hard liquor, 5 US fl oz or 150 mL wine, 12 US fl oz or 350 mL beer; drinking a six-pack of 5% ABV beer daily would be 84 g and just over the upper limit) for 20 years or more in men, or 20 g/day for women ...
The ascending colon is smaller in calibre than the cecum from where it starts. It passes upward, opposite the colic valve, to the under surface of the right lobe of the liver, on the right of the gall-bladder, where it is lodged in a shallow depression, the colic impression; here it bends abruptly forward and to the left, forming the right colic flexure (hepatic) where it becomes the ...
Diverticulitis is a common cause of abdominal pain resulting from outpouchings that particularly affect the colon. Functional colonic diseases refer to disorders without a known cause, including irritable bowel syndrome and intestinal pseudoobstruction.
