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.
This low efficiency is the result of about 40% efficiency of generating ATP from the respiration of food, losses in converting energy from ATP into mechanical work inside the muscle, and mechanical losses inside the body. The latter two losses are dependent on the type of exercise and the type of muscle fibers being used (fast-twitch or slow ...
Meat production and trade substantially increase risks for infectious diseases , including of pandemics, whether though contact with wild and farmed animals, or via husbandry's environmental impact. [97] [98] For example, avian influenza from poultry meat production is a threat to human health. [99]

It argues the hypothesis that cooking food was an essential element in the physiological evolution of human beings. It was shortlisted for the 2010 Samuel Johnson Prize.
The Human Cell Atlas project, which started in 2016, had as one of its goals to "catalog all cell types (for example, immune cells or brain cells) and sub-types in the human body". [13] By 2018, the Human Cell Atlas description based the project on the assumption that "our characterization of the hundreds of types and subtypes of cells in the ...
Spoiled meat changes color and exudes a foul odor. Ingestion can cause serious food poisoning. Salt-curing processes were developed in antiquity [9] in order to ensure food safety without relying on then unknown anti-bacterial agents. The short shelf life of fresh meat does not pose significant problems when access to it is easy and supply is ...
It is both the heaviest internal organ and the largest gland in the human body. It is located in the right upper quadrant of the abdominal cavity, resting just below the diaphragm, to the right of the stomach, and overlying the gallbladder. [5] The liver is connected to two large blood vessels: the hepatic artery and the portal vein.
