what does it mean to physiologically ineffective in terms of dead space and shunted blood

The specialty of analytical chemistry applied to assays of physiologically important substances found in blood, urine, tissues, and other biological fluids for the purpose of aiding the physician in making a diagnosis or following therapy. Respiratory dead-space is often increased in lung disease. Anatomic dead space is the total volume of the conducting airways from the nose or mouth down to the level of the terminal bronchioles, and is about 150 ml on the.

There are two different ways to define dead space- anatomic and physiologic. Physiologically, this agent causes relaxation of bronchial smooth muscle, produces vasodilation (except in cerebral vessels), stimulates cardiac muscle, as well as induces diuresis and gastric acid secretion. Dead space is the portion of each tidal volume that does not take part in gas exchange. It also may be a physiologically relevant docking site for calcineurin. (Scientists identify how the exosomes of the parasite responsible for Chagas disease affect heart cells, University of Granada) Production by a cell or aggregation of cells (a gland) of a physiologically active substance and its movement out of the cell or organ in which it is formed.Įxosomes are nanovesicles released by cells that play an important role in transmitting biological components, both physiologically and pathologically. (For species that mate for life, bonding behaviors provide advantages, National Science Foundation) Why are physiologically costly behaviors retained in long-term reproductive partnerships? (Genetic Information Processing Pathway, NCI Thesaurus)Ī therapeutic formulation of the primary physiologically active form of endogenous thyroid hormone. Dietary phospholipids also include molecules derived physiologically from this basic structure.Ī sequence of biological or biochemical events that are involved in the conversion of genetic information into physiologically active molecules, such as functional RNA and proteins.
