Human physiology

The breasts are two prominences located on the upper ventral region of the torso in humans and other primates. Both sexes develop breasts from the same embryological tissues. The relative size and development of the breasts is a major secondary sex distinction between females and males. There is also considerable variation in size between individuals. Permanent breast growth during puberty is caused by estrogens in conjunction with the growth hormone. Female humans are the only mammals that permanently develop breasts at puberty; all other mammals develop their mammary tissue during the latter

thumb|upright=1.15|Human tears Tears (tear film) are a transparent fluid secreted primarily by the lacrimal glands (tear gland) found in the eyes of all land mammals. According to the mode of production, tears are classified into four types: basal, closed eye, emotional, and reflex. The basal rate of tear secretion is ~0.5–2.2 μL/min, and irritation can increase secretion by up to ~100-fold, reaching ~300 μL/min. Tears are made up of water, electrolytes, proteins, lipids, and mucins that form layers on the surface of eyes. The four types of tears differ significantly in their composition. upr

Inflammation (from ) is part of the biological defence response of body tissues. Inflammatory immunovascular responses can be triggered by a broad range of stimuli, including physical trauma, "dead, damaged, malfunctioning or stressed tissues", pathogens, irritants, toxins, overuse, autoimmunity, allergens, and foreign bodies (e.g. silica and asbestos). The five cardinal signs are heat, pain, redness, swelling, and loss of function (Latin calor, dolor, rubor, tumor, and functio laesa).

Auxology (from Greek , auxō, or , auxanō 'grow'; and , -logia) is a meta-term covering the study of all aspects of human physical growth. (Although, it is also fundamental of biology.) Auxology is a multi-disciplinary science involving health sciences/medicine (pediatrics, general practice, endocrinology, neuroendocrinology, physiology, epidemiology), and to a lesser extent: nutrition science, genetics, anthropology, anthropometry, ergonomics, history, economic history, economics, socio-economics, sociology, public health, and psychology, among others.

Hyperchlorhydria, sometimes called chlorhydria, sour stomach or acid stomach, refers to the state in the stomach where gastric acid levels are higher than the reference range. The combining forms of the name (chlor- + hydr-), referring to chlorine and hydrogen, are the same as those in the name of hydrochloric acid, which is the active constituent of gastric acid.

Hepoxilins (Hx) are a set of epoxyalcohol metabolites of polyunsaturated fatty acids (PUFA), i.e. they possess both an epoxide and an alcohol (i.e. hydroxyl) residue. HxA3, HxB3, and their non-enzymatically formed isomers are nonclassic eicosanoid derived from acid the (PUFA), arachidonic acid. A second group of less well studied hepoxilins, HxA4, HxB4, and their non-enzymatically formed isomers are nonclassical eicosanoids derived from the PUFA, eicosapentaenoic acid. Recently, 14,15-HxA3 and 14,15-HxB3 have been defined as arachidonic acid derivatives that are produced by a different metabol
