hich type of cell adaptation occurs when normal columnar ciliated epithelial cells of the bronchial lining have been replaced by stratified squamous epithelial cells

The question is incomplete , as the options are not given. Here are the options.

A. Hyperplasia

b. Metaplasia

C. Dysplasia

D. Anaplasia

The correct option is b.

Metaplasia

Explanation:

This because metaplasia is the process where by one mature cell can be replaced by another cell in the body. This is a reversible replacement that take place in the cell of the body. In this kind of replacement, a less differentiated cell replaced the mature cell. It occur when normal columnar ciliated epithelial cells of the bronchial lining have been replaced by stratified squamous epithelial cells.

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.
