Aveolar macrophages work to break up surfactanct in the aveoli which exists to decrease surface tension in the lungs. If there is a disorder where the macrophage does not function correctly, such as in PAP, the surfactant will not be broken up and decreased ventilation will occur resulting in less oxygen delivery.
What else can I help you with?
Function of alveolar ducts?
Trap air in lungs (act as air pockets 4 gaseous exchange).
What is pulmonary alveolar proteinosis?
Pulmonary alveolar proteinosis (PAP) is a rare disease of the lungs.
What is an alveolar dead space?
An alveolar dead space is the volume of air in the alveoli of the lungs which does not partake in gas exchange.
What are the most numerous cells in the lungs?
The most numerous cells in the lungs are the alveolar epithelial cells, specifically the type I alveolar cells which make up about 95% of the alveolar surface area. These cells are responsible for gas exchange and maintaining the structural integrity of the alveoli.
Site of alveolar-capillary oxygen exchange?
Within the lungs.
What is function of ventilation?
The main function of the pulmonary vein is to carry oxygenated blood from the lungs to the left atrium. Then it is transferred to the aorta, which takes the blood to the head and arms.
What might cause damage to the alveolar sacs?
Damage to the alveolar sacs can be caused by smoking, air pollution, respiratory infections, or long-term exposure to harmful fumes and chemicals. These factors can lead to conditions like emphysema, fibrosis, or bronchiectasis, all of which can impair the function of the alveolar sacs in the lungs.
What is alveolar connective tissue?
Alveolar connective tissue is a type of loose connective tissue found in the alveoli of the lungs. It provides support and structure to the alveoli, which are responsible for gas exchange in the lungs. Additionally, alveolar connective tissue contains capillaries that facilitate the exchange of oxygen and carbon dioxide between the lungs and the bloodstream.
What is the total alveolar surface area in the lungs of human beings?
100m2
What kind of epithelial tissue is in the alveolar sacs of the lungs?
Simple Squamous
Where do blood cells pick up oxygen?
In the lungs, in the alveolar capillaries
What is a conducting structure in the Lungs?
Respiratory bronchioles, alveolar ducts, and alveoli.
