Human skin pigmentation varies substantially between populations; this has led to the classification of people(s) on the basis of skin colour. [3] In terms of surface area, the skin is the second largest organ in the human body (the inside of the small intestine is 15 to 20 times larger).
In physiology and medicine, the body surface area (BSA) is the measured or calculated surface area of a human body.For many clinical purposes, BSA is a better indicator of metabolic mass than body weight because it is less affected by abnormal adipose mass.
These models use whole body surface area rather than the surface area of specific parts for the mathematical input. c. The third scenario is splash, or droplet exposure. This model takes into account that not all water carrying a chemical that comes into contact with skin stays on the skin long enough to allow absorption.
The skin is one of the largest organs of the body. In humans, it accounts for about 12 to 15 percent of total body weight and covers 1.5 to 2 m 2 of surface area. [1] 3D still showing human integumentary system. The skin (integument) is a composite organ, made up of at least two major layers of tissue: the epidermis and the dermis. [2]
Total body surface area (TBSA) is an assessment of injury to or disease of the skin, such as burns or psoriasis. In adults, the Wallace rule of nines can be used to determine the total percentage of area burned for each major section of the body.
Surface projections of the major organs of the trunk, using the vertebral column and rib cage as main reference points of surface anatomy. Surface anatomy (also called superficial anatomy and visual anatomy) is the study of the external features of the body of an animal. [1] In birds, this is termed topography.
The skin weighs an average of four kilograms, covers an area of two square metres, and is made of three distinct layers: the epidermis, dermis, and subcutaneous tissue. [1] The two main types of human skin are: glabrous skin, the hairless skin on the palms and soles (also referred to as the "palmoplantar" surfaces), and hair-bearing skin. [3]
Additionally, the increase in the surface area prevents the dermal and epidermal layers from separating by strengthening the junction between them. With age, the papillae tend to flatten and sometimes increase in number. [7] The skin of the hands and fingers and the feet and toes is known by forensic scientists as friction ridge skin.
