Sub Sections: — Anatomy and Physiology — Health and Diseases
The Human Body section focuses on the organization, functioning, and integration of the biological systems that make up the human organism. It is a systemic and physiological approach to understanding the complexity of the human body, analyzed at multiple levels: molecular, cellular, tissue, organic, and systemic.
Topics covered include:
The scientific study of the human body allows us to understand not only normal physiology, but also the biological basis of disease and therapeutic interventions, constituting an essential foundation for medical sciences, applied biology and the health professions.
The allantois is an essential structure in vertebrate development, playing a vital role in waste storage and gas exchange. It is a sac-like structure that forms as an outgrowth of the embryo’s digestive tract, and is a part of the…
Albinism is a genetic condition characterized by a reduced amount or complete absence of melanin pigment in the skin, hair, and eyes or in the eyes alone. This condition is associated with a number of vision abnormalities and is caused…
Introduction Aldosterone, a hormone produced by the adrenal glands, plays an essential role in maintaining sodium and potassium balance in the body. This steroid hormone is part of the renin-angiotensin-aldosterone system (RAAS), a vital hormonal cascade involved in blood pressure…
Introduction Alcohol dehydrogenase (ADH) is a group of dehydrogenase enzymes that facilitate the interconversion between alcohols and aldehydes or ketones, with the reduction of nicotinamide adenine dinucleotide (NAD+) to NADH. This enzyme family plays a critical role in the metabolism…
Adiponectin, an adipocyte-derived plasma protein, is gaining attention in the fields of endocrinology and cardiology due to its crucial role in several physiologic and pathologic processes. Herein, we will delve into what adiponectin is, its functions, its role in diseases,…
Introduction Adipocytes, also known as fat cells, play a crucial role in energy homeostasis and metabolic function in the human body. They are largely categorized into two types – white adipocytes and brown adipocytes, each with its unique functions and…
Introduction Adenylate Cyclase (AC) is a crucial enzyme that plays a significant role in the intricate network of cellular communication. It is responsible for converting adenosine triphosphate (ATP), the cell’s primary energy source, into cyclic adenosine monophosphate (cAMP). This transformation…
The field of biology is an ever-evolving one, opening up new vistas of understanding about the microcosmic world within us. One such microscopic structure that plays a crucial role in the process of reproduction is the acrosome. This article provides…
Introduction Omega-3 fatty acids are polyunsaturated fatty acids (PUFAs) that play essential roles in human health and biology. They are considered crucial dietary nutrients, as humans, like other mammals, cannot synthesize them independently (Simopoulos, 2002, The American Journal of Clinical…
Introduction Acetylcholine is a vital neurotransmitter, the chemical messenger responsible for transmitting signals between nerve cells within the nervous system. Its discovery by Otto Loewi in the early 20th century marked a significant breakthrough in neuroscience, enabling researchers to delve…
