Human Body Parts And Functions In Tamil Pdf 18 WORK


When performing pulmonary function tests, body position plays a role in its influence over test results. As seen in this review, a change in body position may have varying implications depending on the patient populations. American Thoracic Society (ATS) guidelines [2] recommend performing PFTs in the sitting or standing position, but the sitting position is usually preferred. The norms of those functions according to gender and age were established from tests performed in this position. This review suggests that for most of the subjects this is the preferred position for the test; however, clinicians should consider performing PFTs in other positions in selected patients. In patients with SCI, testing also in the supine position may provide important information. In patients with neuromuscular disorders, performing PFTs in the supine position may help to assess diaphragmatic function.

Mobile phones communicate by transmitting radio waves through a network of fixed antennas called base stations. Radiofrequency waves are electromagnetic fields, and unlike ionizing radiation such as X-rays or gamma rays, can neither break chemical bonds nor cause ionization in the human body.


Tissue heating is the principal mechanism of interaction between radiofrequency energy and the human body. At the frequencies used by mobile phones, most of the energy is absorbed by the skin and other superficial tissues, resulting in negligible temperature rise in the brain or any other organs of the body.


Organomegaly can be a sign of disease and pathologic abnormality, although standard tables defining organomegaly have yet to be established and universally accepted. This study was designed to address the issue and to determine a normal weight for the major organs in adult human males. A prospective study of healthy men aged 18 to 35 years who died of sudden, traumatic deaths was undertaken. Cases were excluded if there was a history of medical illness including illicit drug use, if prolonged medical treatment was performed, if there was a prolonged period between the time of injury and death, if body length and weight could not be accurately assessed, or if any illness or intoxication was identified after gross and microscopic analysis including evidence of systemic disease. Individual organs were excluded if there was significant injury to the organ, which could have affected the weight. A total of 232 cases met criteria for inclusion in the study during the approximately 6-year period of data collection from 2005 to 2011. The decedents had a mean age of 23.9 years and ranged in length from 146 to 193 cm, with a mean length of 173 cm. The weight ranged from 48.5 to 153 kg, with a mean weight of 76.4 kg. Most decedents (87%) died of either ballistic or blunt force (including craniocerebral) injuries. The mean weight of the brain was 1407 g (range, 1070-1767 g), that of the liver was 1561 g (range, 838-2584 g), that of the spleen was 139 g (range, 43-344 g), that of the right lung was 445 g (range, 185-967 g), that of the left lung was 395 g (range, 186-885 g), that of the right kidney was 129 g (range, 79-223 g), and that of the left kidney was 137 g (range, 74-235 g). Regression analysis was performed and showed that there were insufficient associations between organ weight and body length, body weight, and body mass index to allow for predictability. The authors, therefore, propose establishing a reference range for organ weights in men, much like those in use for other laboratory tests including hemoglobin, hematocrit, or glucose. The following reference ranges (95% inclusion) are proposed: brain, 1179-1621 g; liver, 968-1860 g; spleen, 28-226 g; right lung, 155-720 g; left lung, 112-675 g; right kidney, 81-160 g; and left kidney, 83-176 g.


When you hear of plastic surgery, what do you think of? A Hollywood star trying to delay the effects of aging? People who want to change the size of their stomachs, breasts, or other body parts because they see it done so easily on TV?


You need vitamin C for the growth and repair of tissues in all parts of your body. It helps the body make collagen, an important protein used to make skin, cartilage, tendons, ligaments, and blood vessels. Vitamin C is needed for healing wounds, and for repairing and maintaining bones and teeth. It also helps the body absorb iron from nonheme sources.


Mechanical engineering is one of the broadest engineering disciplines. Mechanical engineers design, develop, build, and test. They deal with anything that moves, from components to machines to the human body.


The prostate is in front of the rectum and just below the bladder. The gland surrounds the urethra at the neck of the bladder. The bladder neck is the area where the urethra joins the bladder. The urethra is the tube that carries urine from the bladder to the outside of the body. In men, the urethra also carries semen out through the penis during sexual climax, or ejaculation. The bladder and urethra are parts of the lower urinary tract.
