All connective tissue apart from blood and lymph consists of three main components: fibers (elastic and collagenous fibers), ground substance and cells. (Not all authorities include blood or lymph as connective tissue.) Blood and lymph lack the fiber component.All are immersed in the body water.onnective tissue (CT) is one of the four types of biological tissue that support, connect, or separate different types of tissues and organs in the body.
Degradation of the metal substrate by oxidation. That is the formation of an oxide layer on the metal surface. This process requires that the metal surface be exposed to oxygen, and is favoured in the presence of water.
The oxidation of a metal occurs when the metal loses one or more electrons, so that the atoms of the metal go from the neutral state and become a positively charge ion. This commonly results in the formation of a metal oxide (in the case of iron, that is known as rust). It occurs in the presence of oxygen. For example, 1  Iron> (water +oxygen)= iron oxide. 2  mercury>(heat above 350 Â°C + oxygen)= Mercury oxide.  sodium>(water, even slight vapor in air+ oxygen) = sodium oxide.
