Pulmonary respiration-also called ventilation-is composed of two components: alveolar ventilation and dead space ventilation. Dead space ventilation is the portion of the respiratory volume that is not involved in the exchange of carbon dioxide (CO2) for oxygen (O2). Dead space ventilation occurs because the volume of air that is in the upstream system of the … Dead Space Ventilation: Function, Tasks, Role & Diseases
The erythrocyte deformability or flexibility of red blood cells enables the cells to pass through vessels with different lumens. In addition, erythrocytes change shape depending on the temperature and flow rate of the blood, with concomitant changes in blood viscosity. Abnormal shape is assumed by erythrocytes in the context of spherical or sickle cell anemia, … Erythrocyte Deformability: Function, Role & Diseases
During erythrocyte aggregation, red blood cells cluster together and clump together. The phenomenon is physiologic to some degree, especially in the smaller capillaries. In immune complex diseases, for example, this physiologic degree is exceeded. What is erythrocyte aggregation? In erythrocyte aggregation, red blood cells cluster together and clump together. Red blood cells are also called … Erythrocyte Aggregation: Function, Role & Diseases
Vital capacity is a parameter of spirometry. It provides information about lung function during inhalation and exhalation. If expiratory vital capacity is significantly different from inspiratory vital capacity, lung disease is probably present. What is vital capacity Vital capacity is a parameter of spirometry. It provides information about lung function during inhalation and exhalation. Spirometry … Vital Capacity: Function, Tasks, Role & Diseases
Semipermeability refers to biomembranes that are selectively permeable to certain substances and cannot be passed by other substances. Semipermeability is the basis of osmosis and characterizes the cells of all living things. Disturbances in semipermeability have devastating consequences for electrolyte and water balance in cellular compartments. What is semipermeability? Semipermeability refers to biomembranes that are … Semipermeability: Function, Role & Diseases
Without respiration there is no metabolism and without metabolism there is no life. Thus, humans and all vertebrates depend on gas exchange via pulmonary respiration. What is gas exchange? Without respiration no metabolism and without metabolism no life. Thus, humans and all vertebrates depend on gas exchange via pulmonary respiration. Oxygen, which is so vital … Gas Exchange: Function, Tasks, Role & Diseases
During respiration, O2 is taken into the blood and CO is released through the blood. The oxygen tension or oxygen partial pressure is the proportion of oxygen in the blood gas mixture. The physician usually determines all blood gases for clinical diagnosis and thus gathers evidence of respiratory insufficiency, for example. What is oxygen tension? … Oxygen Tension: Function, Tasks, Role & Diseases
Distribution is the uneven distribution of ventilation (aeration of the lungs), perfusion (blood flow to the lungs), and diffusion (gas exchange). This reduces arterialization of the blood even in healthy individuals. Arterialization describes the setting of arterial respiratory gas partial pressures. What is distribution? Distribution is the uneven distribution of ventilation (aeration of the lungs), … Distribution: Function, Tasks, Role & Diseases
Respiratory rate refers to the number of breaths taken by a living being within a given time. It is usually measured and specified for a period of one minute. An adult human takes about twelve to 18 breaths in one minute. Proper respiratory rate is critical for optimal oxygen saturation of the blood. What is … Respiratory Rate: Function, Tasks, Role & Diseases
Permeability is the permeability of inorganic or organic solids to a so-called permeate. This permeate can correspond to gases, liquids, or other molecules and is relevant in the body, for example, to cell membranes and blood vessels. In psychology, on the other hand, permeability is receptivity to subconscious impulses. What is permeability? Biological membranes are … Permeability: Function, Role & Diseases
Decompression sickness type II In DCS II, the brain, spinal cord and inner ear are affected. Here, it is not so much the direct formation of gas bubbles in the tissue itself that causes the damage, but rather the gas embolisms that lead to blockages in the small vessels. The damage to the brain can … Decompression sickness type II | Diving Disease
History The connection between pressure and the solubility of gases in liquids was established as early as 1670 by Robert Boyle.However, it was not until 1857 that Felix Hoppe-Seyler established the theory of gas embolism as the cause of decompression sickness. There were then further investigations on diving depth and diving time. However, it was … History | Diving Disease
