This sensory information is used primarily in autonomic reflexes that in turn influence the heart cardiac output and vascular smooth muscle to influence vascular resistance. [1] Baroreceptors act immediately as part of a negative feedback system called the baroreflex , [ 2 ] as soon as there is a change from the usual mean arterial blood ...
Gastrointestinal physiology is the branch of human physiology that addresses the physical function of the gastrointestinal (GI) tract.The function of the GI tract is to process ingested food by mechanical and chemical means, extract nutrients and excrete waste products.
Cardiac physiology or heart function is the study of healthy, unimpaired function of the heart: involving blood flow; myocardium structure; the electrical conduction system of the heart; the cardiac cycle and cardiac output and how these interact and depend on one another.
Many participants found the idea of living in a bunker without time cues daunting, but most ended up enjoying the experiment. [1] Aschoff was the first test subject, with Rütger Wever observing. [2] The experiment began in 1966 and continued until the early 1980s. [1] As of 2013, the bunker was still in existence, although quite dilapidated. [9]
Troponin, or the troponin complex, is a complex of three regulatory proteins (troponin C, troponin I, and troponin T) that are integral to muscle contraction [2] in skeletal muscle and cardiac muscle, but not smooth muscle.
In fluid dynamics, the Hagen–Poiseuille equation is a physical law that gives the pressure drop in a fluid flowing through a long cylindrical pipe. The assumptions of the equation are that the flow is laminar viscous and incompressible and the flow is through a constant circular cross-section that is substantially longer than its diameter.
Neurophysiology is a branch of physiology and neuroscience concerned with the functions of the nervous system and their mechanisms. The term neurophysiology originates from the Greek word νεῦρον ("nerve") and physiology (which is, in turn, derived from the Greek φύσις, meaning "nature", and -λογία, meaning "knowledge"). [1]
Cell culture is one of the major tools used in cellular and molecular biology, providing excellent model systems for studying the normal physiology and biochemistry of cells (e.g., metabolic studies, aging), the effects of drugs and toxic compounds on the cells, and mutagenesis and carcinogenesis.
