The English clergyman Stephen Hales made the first published measurement of blood pressure in 1733. [ 1][ 2] Descriptions of what would come to be called hypertension came from, among others, Thomas Young in 1808 and especially Richard Bright in 1836. [ 1] Bright noted a link between cardiac hypertrophy and kidney disease, and subsequently ...
Triiodothyronine, also known as T3, is a thyroid hormone. It affects almost every physiological process in the body, including growth and development, metabolism, body temperature, and heart rate. [ 1]
35094-2. Blood pressure ( BP) is the pressure of circulating blood against the walls of blood vessels. Most of this pressure results from the heart pumping blood through the circulatory system. When used without qualification, the term "blood pressure" refers to the pressure in a brachial artery, where it is most commonly measured.
Normal human body temperature ( normothermia, euthermia) is the typical temperature range found in humans. The normal human body temperature range is typically stated as 36.5–37.5 °C (97.7–99.5 °F). [ 8][ 9] Human body temperature varies. It depends on sex, age, time of day, exertion level, health status (such as illness and menstruation ...
Regarding ideal numbers, the famous M.D. says: "Your blood pressure is supposed to be under 140 over 90, optimally closer to 120 over 80." He went on to call the test "life-saving" and "the single ...
The first fully automated oscillometric blood pressure cuff called the Dinamap 825, an acronym for "Device for Indirect Non-invasive Mean Arterial Pressure", was made available in 1976. [18] It was replaced in 1978 by the Dinamap 845 which could also measure systolic and diastolic blood pressure, as well as heart rate.
In humans, hyperthermia is defined as a temperature greater than 37.5–38.3 °C (99.5–100.9 °F), depending on the reference used, that occurs without a change in the body's temperature set point. [ 3][ 10] The normal human body temperature can be as high as 37.7 °C (99.9 °F) in the late afternoon. [ 2] Hyperthermia requires an elevation ...
The hypothalamic–pituitary–thyroid axis ( HPT axis for short, a.k.a. thyroid homeostasis or thyrotropic feedback control) is part of the neuroendocrine system responsible for the regulation of metabolism and also responds to stress. As its name suggests, it depends upon the hypothalamus, the pituitary gland, and the thyroid gland .
