  • The main method of cognition of the performance of biological systems is their mathematical modeling. The essence of this method should reflect the principle of optimization in biology[9]. Any biosystem cannot function if its energy consumption is inadequately high. The same is applicable to the blood circulatory system. Its main function is to transport blood throughout the body in order to maintain the proper gaseous exchange, deliver important substances to viscera and tissues in living body and remove decay products.

  • This chapter addresses two systems commonly not considered as ‘dramatic’ as the cardiovascular or nervous systems, and which to the uninformed may appear more complex. Both are vital in not only maintaining health and well-being, but also life, as illnesses affecting the functioning of these systems can be fatal.

  • Physiology plays a major role in the scientific foundation of medicine and other subjects related to human health and physical performance. Pharmacology is the science which deals with the effects of drugs on living systems and their use in the treatment of disease. This book is designed to enhance students’ understanding of physiology and pharmacology via a series of case studies involving human disease and its treatment. Traditional university teaching methods focus on informing students in terms of physiological and pharmacological theory.

  • Diabetes mellitus is a complex, progressive disease, which is accompanied by multiple complications. It is a metabolic disorder of the endocrine system and listed among the most common disorders in both developed and developing countries. It has a global metabolic epidemic and it is estimated that the number of people affected by the disease will rise from the current 150 to 230 million by 2025. Hyperglycaemia is a characteristic feature of diabetes mellitus and chronic hyperglycaemia could lead to long-term complications in the eyes, kidneys, nerves, heart and blood vessels.

  • The aim of the Handbook of Diagnostic Endocrinology is to provide a comprehensive overview of current approaches to the diagnosis of endocrine disorders. Our ability to diagnose patients with diseases of the endocrine systems is expanding exponentially with the development of new and more reliable assay methods and the incorporation of both molecular and genetic approaches into our understanding of the pathophysiology of these diseases.

  • Accurate statistics on cancer occurrence and outcome are essential both for the purposes of research and for planning and evaluation programmes for cancer control (Parkin, 2006). Although tumours of thyroid account for only 1% of the overall human cancer burden, they represent the most common malignancies of the endocrine system and pose a significant challenge to pathologists, surgeons and endocrinologists. Among epithelial tumors, carcinomas of follicular cell origin far outnumber those of C-cell origin.

  • Variation in the morphology of the adult male reproductive system among different groups of Hymenoptera offer characteristics that help studies of behavior and the evolutionary history of this group. The objective of this study was to describe the adult male reproductive system of the wasp Polistes versicolor versicolor Olivier (Vespidae: Polistini). The reproductive systems were dissected, fixed and embedded for light microscopy. In P. v. versicolor, the reproductive system includes a pair of testes, each one with three fusiform follicles.

  • Thermoregulation Heat loss occurs through five mechanisms: radiation (55–65% of heat loss), conduction (10–15% of heat loss, but much greater in cold water), convection (increased in the wind), respiration, and evaporation (which are affected by the ambient temperature and the relative humidity). The preoptic anterior hypothalamus normally orchestrates thermoregulation (Chap. 17). The immediate defense of thermoneutrality is via the autonomic nervous system, whereas delayed control is mediated by the endocrine system.

  • Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) are rare and heterogeneous neoplasms with overall increasing incidence, but not an associated increase in survival rate over the past few decades. Tumors originate from at least 16 different cells of diffuse endocrine system (DES), scattered through mucosa of gastrointestinal tract. They are mainly sporadic, but sometimes exhibit familial inheritance.

  • Synthetic chemicals known as endocrine disruptors are an excellent example of emerging contaminants where the threats and consequences for water quality, human health, and the environment are still not fully understood. Endocrine disruptors – chemicals that can interfere with hormone action – have been identified among chemicals used in agriculture, industry, and households, and for personal care, including pesticides, disinfectants, plastic additives, and pharmaceuticals like birth control pills.

  • This lab uses freshwater sponges as model organisms to examine the biological effects of water pollution. Specifically, the focus of this laboratory module is on the effects that chemicals of environmental concern (e.g., endocrine disrupters) have on sponge growth and development. Contamination of aquatic ecosystems is a serious issue in environmental science. Identifying which chemicals we should be concerned with, and determining the consequences of contamination by specific compounds, is a major area of current research.

  • Common household products –detergents, disinfectants, plastics, and pesticides– contain chemical ingredients that enter the body, disrupt hormones and cause adverse developmental, disease, and reproductive problems. Known as endocrine disruptors, these chemicals, which interact with the endocrine system, wreak havoc in humans and wildlife.
