Hering-Breuer
The reflex associated with the sensory stimulation of the pulmonary stretch receptors is known as the Hering-Breuer reflex. It is responsible for inhibiting inspiration to prevent overinflation of the lungs, promoting expiration and maintaining normal breathing patterns.
Your right side of the heart pumps blood in the pulmonary circulation. The pulmonary circulation should start from the origin of the pulmonary aorta.
Pulmonary is a term relating to the respiratory system; pulmonary diseases include empyhsema, bronchitis & asthma.
Pulmonary stenosis is almost entirely congenital.
fibrosis
They damage the alveolar-capillary membrane
Pulmonary Ventilation consists of inspiration/inhaling, and expiration/exhaling
Lung hyperinflation stimulates pulmonary stretch receptors. A person who experience lung hyperinflation can end up having COPD or chronic obstructive pulmonary disease.
Decreased pulmonary blood flow alone does not cause cyanosis. It is when decreased pulmonary blood flow is associated with right to left shunting (ie Tetralogy of fallot) that it is associated with cyanosis.
narrowing of the pulmonary vessels due to decreased oxygen and increased carbon dioxide
vasoconstriction of the pulmonary blood vessels
The Pulmonary Blood Circuit
Pulmonary circulation through the blood vessels and capillaries.
There are two parts. Inhalation and exhalation also known as inspiration and expiration. Inspiration is the process of breathing air into the lungs it helps in oxygenation. Expiration is breathing out and it does not require any specific muscle activity. Expiration occurs due to elastic recoiling of the lungs after inspiration
A Pulmonary Infarction is the death of a small area of lung resulting from pulmonary embolism. It occurs in a small, dead-end pulmonary artery and often causes pain in the back or chest.PI is an an infrequent consequence of Pulmonary Edema(< 10% of cases). It is sometimes due to thrombosis in situ of the pulmonary arteries as might occur in congenital heart disease associated with severe pulmonary hypertension or in hematologic disorders (eg, sickle cell anemia).
A pulmonary infiltrate is a substance denser than air, such as pus, blood, or protein, which lingers within the parenchyma of the lungs. Pulmonary infiltrates are associated with pneumonia, tuberculosis and sarcoidosis.
The right side is the pulmonary circuit. (The left side is the systemic circuit.)
