I was immediately interested, because I've been steeped in height and weight numbers for years now, trying to complete my photographic height weight chart. 2003 May;34(3):273-8. doi: 10.1016/S0003-6870(03)00007-3. A very tall thin man can have the same BSA as a short round woman. [Assume a height of 5'8" (170 cm) and a mass of 150 lb (68 kg).] Based on the data, which type of cell would be best suited for lining the alveoli of the lungs, where diffusion of carbon dioxide and oxygen must occur very rapidly? According to InnerBody, the inner surface area of the human lungs measures between 80 and 100 square meters, which is comparable in size to half of a tennis court. Epub 2015 Aug 24. 2003 Jan;58(1):50-5. doi: 10.1046/j.1365-2044.2003.02788_1.x. In the following formulae, BSA is expressed in m , weight (or, more properly, mass) W in kg, and height H in cm. J. Appl. to 3 square meters (6'3" and 370 lbs. Eight normal human lungs obtained from patients dying from causes not related to the lung were subjected to morphometric analysis to determine the number of cells in the alveolar region and their mean volume and surface characteristics. Jane and I tried to calculate the surface area of Dave Grohl. COVID-19 is an emerging, rapidly evolving situation. Scientists have used refined microscopic techniques that … The surface area of the mouth was measured to calculate the average thickness of the salivary film which separates the opposing layers of the oral mucosa and which also overlies the dental plaque.. A representative subset of the entire sample population involving 12 men and 12 women (G24) was selected for detailed measurements of hand surface area (SAhand) and ratios of surface area to volume (SA/VOL) of various body segments. We wrapped him in a tight skin of aluminum foil, then unwrapped it and measured the area of the flat foil. The SA/VOL ratios of the various body segments were higher for the women compared to the men of G24, significantly for the head plus neck (by 7%), torso (19%), upper arms (15%), forearms (20%), hands (18%), and feet (11%). Would you make any changes to the calculation? Int J Numer Methods Heat Fluid Flow. Body surface area of Africans: a study based on direct measurements of Nigerian males. Such resolutions yield a contact area of approximately 500 sensors (for a typical adult human foot with surface area of approximately 100 cm 2). Physiological and Psychological Responses during Exercise and Recovery in a Cold Environment Is Gender-Related Rather Than Fabric-Related. The development of three dimensional laser scanning technology and sophisticated graphics editing software have allowed an alternative and potentially more accurate determination of body surface area (BSA). The human foot takes an incredible amount of abuse; I sometimes wonder at how such a complicated system of bones, joints, and tendons can do such a complicated task thousands of times per day, while a toaster only cooks bread, on a level surface, but lasts a fraction as long as the average foot! References Clauser, C., McConville, J., Young, J. The purpose of this study is to establish a foot surface area (FSA) database and estimation formula based on 3-D foot scan data. A student calculated the average surface area-to-volume ratio of four different types of human epithelial cells. In simple terms, body surface area is the area covered by one's skin - the largest organ of the body. 2018. Background and aim:This study was aimed to determine the total body surface area and percents of both palmar surface of the whole hand (hand surface area) and palm without fingers (palm surface area) in our population. Nucl Med Commun. Dete- surface area, derived from known weight and height by iniion of human body volume from height and weight. Evaluate the constants and b, and predict what the surface … For a stance phase duration of approximately 0.6 seconds during normal walking, [11] approximately 150,000 pressure values, depending on the hardware specifications, are recorded for each step. High-Resolution Three-Dimensional Photonic Scan-Derived Equations Improve Body Surface Area Prediction in Diverse Populations. Scand J Gastroenterol. Ali is a nurse, and she actually has to do this calculation when she is preparing doses for cancer patients undergoing chemotherapy. About ten years ago, in the New York City studios of MTV, my sister Jane and I tried to calculate the surface area of Dave Grohl, guitarist for the Foo Fighters. September 2012; Pharmacotherapy 32(9):856 … To determine the growth rate of the human heart in relation to body surface area, normal data obtained by echocardiography and angiocardiography were analyzed with respect to changes in body size occurring between infancy and adulthood.
