Toppr Admin · Accepted Answer

Alveoli of the lungs is lined by a single layer of closely spaced cells known as simple squamous epithilial cells- Unlike cells found in the respiratory tract- they lack cilia and they help in diffusion of gases-Hence the correct option is B-

	I		II
(a)	Simple squamous epithelium	(i)	Ureters
(b)	Simple cuboidal epithelium	(ii)	Epididymis
(c)	Nonciliated simple columnar epithelium	(iii)	Lining of alveoli of lungs
(d)	Transitional epithelium	(iv)	Lining of thyroid vesicles
(e)	Pseudostratified nonciliated columnar epithelium	(v)	Mucosa of stomach and intestine

	Column I		Column II
A	Squamous epithelium	1	Fallopian tubes
B	Cuboidal epithelium	2	Lining of stomach
C	Columnar epithelium	3	Ducts of glands
D	Ciliated epithelium	4	Air sacs of lungs
