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. [1]
Both circuits transport blood but they can also be seen in terms of the gases they carry. The pulmonary circulation collects oxygen from the lungs and delivers carbon dioxide for exhalation. The systemic circuit transports oxygen to the body and returns relatively de-oxygenated blood and carbon dioxide to the pulmonary circuit. [1]
The circulatory system is further divided into two major circuits – a pulmonary circulation, and a systemic circulation. [8] [1] [3] The pulmonary circulation is a circuit loop from the right heart taking deoxygenated blood to the lungs where it is oxygenated and returned to the left heart.
Pulmocutaneous circulation is part of the amphibian circulatory system.It is responsible for directing blood to the skin and lungs. Blood flows from the ventricle into an artery called the conus arteriosus and from there into either the left or right truncus arteriosus.
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 .
In cardiology, a cardiac shunt is a pattern of blood flow in the heart that deviates from the normal circuit of the circulatory system.It may be described as right-left, left-right or bidirectional, or as systemic-to-pulmonary or pulmonary-to-systemic.
Because of the dual blood supply to the lungs from both the bronchial and the pulmonary circulation, this tissue is more resistant to infarction. An occlusion of the bronchial circulation does not cause infarction, but it can still occur in pulmonary embolism when the pulmonary circulation is blocked and the bronchial circulation cannot fully ...
Pulmonology (/ ˌ p ʌ l m ə ˈ n ɒ l ə dʒ i /, / ˌ p ʊ l m ə ˈ n ɒ l ə dʒ i /, from Latin pulmō, -ōnis "lung" and the Greek suffix -λογία-logía "study of"), pneumology (/ n ʊ ˈ m ɒ l ə dʒ i, n j ʊ-/, built on Greek πνεύμων pneúmōn "lung") or pneumonology [1] (/ n ʊ m ə n ˈ ɒ l ə dʒ i, n j ʊ-/) is a medical specialty that deals with diseases involving ...
