Histology is the study of tissues. There are only four primary tissue types: epithelial, connective, muscular and neural. For now we will only concentrate on epithelial and connective tissues. Epithelial tissue covers exposed surfaces or lines internal cavities or passageways and forms glands.
The Cathedral of Learning in Bangkokâs Assumption University soars to a towering 522 feet (159 meters) in height. Built in 2002, the 39-story structure mimics the design of the University of Pittsburghâs Cathedral of Learning â albeit in a more postmodern style.
But the Washington Monument never factored into the height limit. That being said, at 555 feet, it is still the tallest structure in Washingtonâ but not the highest point. That title goes to the National Cathedral, which is 676 feet above sea level (even though itâs only 301 feet tall) because it sits on a hill.
