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.
The endocardium underlies the much more voluminous myocardium, the muscular tissue responsible for the contraction of the heart. The outer layer of the heart is termed epicardium and the heart is surrounded by a small amount of fluid enclosed by a fibrous sac called the pericardium. 1 Function.
