Ostwald process. The Ostwald process is chemical process for producing nitric acid, which was developed by Wilhelm Ostwald (patented 1902). It is a mainstay of the modern chemical industry. Historically and practically it is closely associated with the Haber process, which provides the requisite raw material, ammonia. Description.
The heart consists of three tissue layers: endocardium, myocardium, and pericardium. The endocardium, the innermost layer, lines the hearts chambers and is bathed in blood. Thâ¦e myocardium is the thick middle layer of the heart. Its cells are unique in that they physically resemble skeletal muscle but have electrical properties similar to smooth muscle.
Despite differences in thickness, the structural organization of the wall is basically the same throughout the heart. The outer walls of the heart chambers consists of three tissue layers: a relatively thick myocardium is sandwiched between an outer epicardium, that covers the wall, and an inner endocardium, that lines the chamber.
