#3. I spray painted the ceiling (floor joists and subfloor) of the unfinished basement of our 1925 house about six months ago. I used white Zinnnser 123 primer and did not even bother to put anything over it. The point was to lighten it and brighten it up and it worked very well for that.
Pulmonary atresia. Pulmonary atresia is a congenital malformation of the pulmonary valve in which the valve orifice fails to develop. The valve is completely closed thereby obstructing the outflow of blood from the heart to the lungs. The pulmonary valve is located on the right side of the heart between the right ventricle and pulmonary artery.
From Wikipedia, the free encyclopedia. A pulmonary sequestration (bronchopulmonary sequestration or cystic lung lesion), is a medical condition wherein a piece of tissue that ultimately develops into lung tissue is not attached to the pulmonary arterial blood supply, as is the case in normally developing lung. Contrast-enhanced MRA or even conventional T1-weighted spin-echo (SE) images may help in the diagnosis of pulmonary sequestration by demonstrating a systemic blood supply, particularly from the aorta, to a basal lung mass.
