Glossopharyngeal breathing (GPB, glossopharyngeal insufflation, buccal pumping, or frog breathing) is a means of pistoning air into the lungs to volumes greater than can be achieved by the person's breathing muscles (greater than maximum inspiratory capacity).
He wrote his thesis on the respiration through the skin and lungs in frogs: Respiratory Exchange of Animals, 1915. Later Krogh took on studies of water and electrolyte homeostasis of aquatic animals and he published the books: Osmotic Regulation (1939) and Comparative Physiology of Respiratory Mechanisms (1941). He contributed more than 200 ...
By redirecting blood flow from poorly-ventilated lung regions to well-ventilated lung regions, HPV is thought to be the primary mechanism underlying ventilation/perfusion matching. [ 1 ] [ 2 ] The process might initially seem counterintuitive, as low oxygen levels might theoretically stimulate increased blood flow to the lungs to increase gas ...
Ben Carson discovered 3 completely natural ingredients, and as a result, blood pressure disappeared forever,” one Facebook post reads. “Headaches go away, blood cholesterol levels decrease ...
Malpighi's frog dissection in 1661, proved to be a suitable size that could be magnified to display the capillary network not seen in the larger animals. [16] In discovering and observing the capillaries in the frog's lungs, Malpighi studied the movement of the blood in a contained system. [15]
The blood flow through the bird lung is at right angles to the flow of air through the parabronchi, forming a cross-current flow exchange system (Fig. 19). [ 44 ] [ 46 ] [ 49 ] The partial pressure of oxygen in the parabronchi declines along their lengths as O 2 diffuses into the blood.
William Harvey (1 April 1578 – 3 June 1657) [1] was an English physician who made influential contributions to anatomy and physiology. [2] He was the first known physician to describe completely, and in detail, pulmonary and systemic circulation as well as the specific process of blood being pumped to the brain and the rest of the body by the heart (though earlier writers, such as Realdo ...
Pulmonary embolism is blood clots occurring in the lungs. Restricted blood flow in the pulmonary circulation results in alveoli ventilated but not perfused, thus, increasing the V/Q ratio and decreasing gas exchange. It can cause hypoxemia(low oxygen level) and damage part of the lung, which may be treated with anticoagulants.
