[15] [16] The right cerebral hemisphere is typically larger than the left, whereas the cerebellar hemispheres are typically of more similar size. Size of the human stomach varies significantly in adults, with one study showing volumes ranging from 520 cm 3 (32 cu in) to 1,536 cm 3 (93.7 cu in) and weights ranging from 77 grams (2.7 oz) to 453 ...
[1] [2] Thomas visualized the human body shape as an egg or ellipse rather than as the cylinder model that is envisioned in the concept of the BMI. [1] [2] The degree of circularity of an ellipse is quantified by eccentricity, with values between 0 to 1, where 0 is a perfect circle (waist circumference same as height) and 1 is a vertical line.

It has been suggested that the ideal human figure has its navel at the golden ratio (, about 1.618), dividing the body in the ratio of 0.618 to 0.382 (soles of feet to navel:navel to top of head) (1 ⁄ is -1, about 0.618) and Leonardo da Vinci's Vitruvian Man is cited as evidence. [23]
This is a list of units of measurement based on human body parts or the attributes and abilities of humans (anthropometric units). It does not include derived units further unless they are also themselves human-based. These units are thus considered to be human scale and anthropocentric.
Males are, on average, taller, but body shape may be analyzed after normalizing with respect to height. The length of each bone is constant, but the joint angle will change as the bone moves. [ 7 ] The dynamics of biomechanical movement will be different depending on the pelvic morphology for the same principle.

A wide variety of body composition measurement methods exist. The gold standard measurement technique for the 4-compartment model consists of a weight measurement, body density measurement using hydrostatic weighing or air displacement plethysmography, total body water calculation using isotope dilution analysis, and mineral content measurement by dual-energy X-ray absorptiometry (DEXA).

The human gastrointestinal tract consists of the esophagus, stomach, and intestines, and is divided into the upper and lower gastrointestinal tracts. [3] The GI tract includes all structures between the mouth and the anus , [ 4 ] forming a continuous passageway that includes the main organs of digestion, namely, the stomach , small intestine ...
