  2. Pulmonary circulation - Wikipedia

    en.wikipedia.org/wiki/Pulmonary_circulation

    The pulmonary circulation is a division of the circulatory system in all vertebrates. The circuit begins with deoxygenated blood returned from the body to the right atrium of the heart where it is pumped out from the right ventricle to the lungs.

  3. Pulmonary artery - Wikipedia

    en.wikipedia.org/wiki/Pulmonary_artery

    A pulmonary artery is an artery in the pulmonary circulation that carries deoxygenated blood from the right side of the heart to the lungs.The largest pulmonary artery is the main pulmonary artery or pulmonary trunk from the heart, and the smallest ones are the arterioles, which lead to the capillaries that surround the pulmonary alveoli.

  4. Lung - Wikipedia

    en.wikipedia.org/wiki/Lung

    The cross-current respiratory gas exchanger in the lungs of birds. Air is forced from the air sacs unidirectionally (from left to right in the diagram) through the parabronchi. The pulmonary capillaries surround the parabronchi in the manner shown (blood flowing from below the parabronchus to above it in the diagram).

  5. Zones of the lung - Wikipedia

    en.wikipedia.org/wiki/Zones_of_the_lung

    Pulmonary interstitial pressure (Pi) rises as lung volume decreases due to reduced radial tethering of the lung parenchyma. Pi is highest at the base of the lung due to the weight of the above lung tissue. Pi can also rise due to an increased volume of 'leaked' fluid from the pulmonary vasculature (pulmonary edema). An increase in Pi causes ...

    en.wikipedia.org/wiki/File:Respiratory_system...

    English: The respiratory system consists of the airways, the lungs, and the respiratory muscles that mediate the movement of air into and out of the body. Español : Diagrama esquemático del sistema respiratorio humano , mostrando los pulmones , los alvéolos , y los músculos que permiten al aire entrar y salir del cuerpo.

  7. Respiratory system - Wikipedia

    en.wikipedia.org/wiki/Respiratory_system

    The respiratory system (also respiratory apparatus, ventilatory system) is a biological system consisting of specific organs and structures used for gas exchange in animals and plants. The anatomy and physiology that make this happen varies greatly, depending on the size of the organism, the environment in which it lives and its evolutionary ...

  8. Blood–air barrier - Wikipedia

    en.wikipedia.org/wiki/Blood–air_barrier

    Failure of the barrier may occur in a pulmonary barotrauma.This can be a result of several possible causes, including blast injury, swimming-induced pulmonary edema, and breathing gas entrapment or retention in the lung during depressurization, which can occur during ascent from underwater diving or loss of pressure from a pressurized vehicle, habitat or pressure suit.

  9. Capillary - Wikipedia

    en.wikipedia.org/wiki/Capillary

    A capillary is a small blood vessel, from 5 to 10 micrometres in diameter, and is part of the microcirculation system. Capillaries are microvessels and the smallest blood vessels in the body. They are composed of only the tunica intima (the innermost layer of an artery or vein), consisting of a thin wall of simple squamous endothelial cells. [2]
