Insensible perspiration, also known as transepidermal water loss, is the passive vapour diffusion of water through the epidermis. Insensible perspiration takes place at an almost constant rate and reflects evaporative loss from the epithelial cells of the skin. [1] Unlike sweating, the lost fluid is pure without additional solutes. For this ...
These are termed "insensible fluid losses" as they cannot be easily measured. Some sources say insensible losses account for 500 to 650 ml/day (0.5 to 0.6 qt.) of water in adults, [12] [14] while other sources put the minimum value at 800 ml (0.8 qt.). [15] In children, one calculation used for insensible fluid loss is 400 ml/m 2 body surface area.
Web corpus searches show that the acronym TEWL is about 40 times more common than TWL in reference to transepidermal water loss. A large advantage of TEWL is that it has higher specificity to that sense than does TWL, which has more alternative senses, including, most importantly, two other senses having to do with evaporation of body water: thermal work limit (TWL), which is the highest ...
Excess free water or hypotonic water can leave the body in two ways – sensible loss such as osmotic diuresis, sweating, vomiting and diarrhea, and insensible water loss, occurring mainly through the skin and respiratory tract. In humans, dehydration can be caused by a wide range of diseases and states that impair water homeostasis in the body ...
A death certificate is either a legal document issued by a medical practitioner which states when a person died, or a document issued by a government civil registration office, that declares the date, location and cause of a person's death, as entered in an official register of deaths.

By weight, the average adult human is approximately 60% water, and the average child is approximately 65% water. [2] [3] There can be considerable variation in body water percentage based on a number of factors like age, health, water intake, weight, and sex. In a large study of adults of all ages and both sexes, the adult human body averaged ...
The definition of legal death, and its formal documentation in a death certificate, vary according to the jurisdiction. The certification applies to somatic death , corresponding to death of the person, which has varying definitions but most commonly describes a lack of vital signs and brain function. [ 9 ]
