  2. 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 ...

  3. Ventilation–perfusion coupling - Wikipedia

    en.wikipedia.org/wiki/Ventilation–perfusion...

    The increased lung pressure pushes the air out of the lungs. [2] The primary function of ventilation is the replacement of the stale gases in the lungs with oxygen-rich air through the removal of carbon dioxide for oxygenation of the blood. [5] The oxygen is then supplied to the entire body through the circulatory system.

The radius of the knuckle is ( ). Also other sizes are , rest of height ( ) . This shape [6] finds its origin in architecture; see Korbbogen, architectural information.

  5. Hemispherical combustion chamber - Wikipedia

    en.wikipedia.org/wiki/Hemispherical_combustion...

    A hemispherical combustion chamber is a combustion chamber in the cylinder head of an internal combustion engine with a domed "hemispheric" shape. An engine featuring this type of hemispherical chamber is known as a hemi engine. In practice, shapes less than a full hemisphere are typically employed, as are variations (or faceting in parts) of a ...

  6. Pulmonary circulation - Wikipedia

    en.wikipedia.org/wiki/Pulmonary_circulation

    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. In the lungs the blood is oxygenated and returned to the left atrium to ...

  7. Respiratory tract - Wikipedia

    en.wikipedia.org/wiki/Respiratory_tract

    The lungs are the largest organs in the lower respiratory tract. The lungs are suspended within the pleural cavity of the thorax. The pleurae are two thin membranes, one cell layer thick, which surround the lungs. The inner (visceral pleura) covers the lungs and the outer (parietal pleura) lines the inner surface of the chest wall. This ...

    76495. Anatomical terminology. [edit on Wikidata] A bronchopulmonary segment is a portion of lung supplied by a specific segmental bronchus and its vessels. [1][2] These arteries branch from the pulmonary and bronchial arteries, and run together through the center of the segment. Veins and lymphatic vessels drain along the edges of the segment.

  9. Head and neck anatomy - Wikipedia

    en.wikipedia.org/wiki/Head_and_neck_anatomy

    The respiratory system begins in the head and neck, with air entering and leaving the body through the mouth and nose. The respiratory system involving the head and neck includes: the nasal cavity for filtering, moistening, and warming the air; the pharynx or throat which is the combining point for respiratory and digestive system
