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 complete the circuit.
Correction of refractive errors by glasses; Prism therapy (if tolerated, to manage diplopia) Vision Therapy; Patching (mainly to manage amblyopia in children and diplopia in adults) Botulinum toxin injection; Surgical correction; Surgical correction of the hypertropia is desired to achieve binocularity, manage diplopia and/or correct the ...
The blood–air barrier or air–blood barrier, (alveolar–capillary barrier or membrane) exists in the gas exchanging region of the lungs. It exists to prevent air bubbles from forming in the blood , and from blood entering the alveoli .
Diagram of the lungs showing regional variations in V/Q ratio Regional variations. While the ideal V/Q ratio is 1, the ratio in the normal lungs of the healthy individual is approximately 0.8, meaning that the ventilation and perfusion do not equal perfectly. Due to gravity, lower lungs have a relatively greater amount of blood, and upper lungs ...
Lung compliance. Lung compliance, or pulmonary compliance, is a measure of the lung 's ability to stretch and expand (distensibility of elastic tissue). In clinical practice it is separated into two different measurements, static compliance and dynamic compliance. Static lung compliance is the change in volume for any given applied pressure. [1]
FMA. 7158. Anatomical terminology. [ edit on Wikidata] 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 ...
Emphysema. Collateral ventilation is a back-up system of alveolar ventilation that can bypass the normal route of airflow when airways are restricted or obstructed. The pathways involved include those between adjacent alveoli ( pores of Kohn ), between bronchioles and alveoli (canals of Lambert), and those between bronchioles (channels of Martin).
The Intrapulmonary nodes or Lymphatic Vessels of the Lungs originate in two plexuses, a superficial and a deep. The superficial plexus is placed beneath the pulmonary pleura. The deep accompanies the branches of the pulmonary vessels and the ramifications of the bronchi. In the case of the larger bronchi the deep plexus consists of two networks ...
The helium dilution technique is the way of measuring the functional residual capacity of the lungs (the volume left in the lungs after normal expiration ). This technique is a closed-circuit system where a spirometer is filled with a mixture of helium (He) and oxygen.
The pulmonary pleurae ( sg.: pleura) [1] are the two flattened sacs ensheathing each lung, locally appearing as two opposing layers of serous membrane separating the lungs from the mediastinum and the inside surfaces of the surrounding chest walls . The portion of the pleura that covers the surface of each lung is often called the visceral ...
