GENERAL HISTOLOGY

Detailed explanation-1: -Cells make up tissues, tissues make up organs, and organs make up organ systems. The function of an organ system depends on the integrated activity of its organs. For instance, digestive system organs cooperate to process food.

Detailed explanation-2: -Just as cells join together to form tissues, different tissues join together to form organs. An organ is a structure made up of two or more tissues that work together to carry out a specific job. Ex: Your heart, is an organ made up of muscle tissue, blood tissue, and nerve tissue.

Detailed explanation-3: -Tissues come together to form organs. For example, lungs, trachea, etc. Several organs in the body come together to perform a common body function and it is known as organ system.

Detailed explanation-4: -A cluster of cells similar in structure, performing the same particular function forms a tissue. Tissues in turn group together and form the organs. In turn, the organ system is formed when a group of organs is dedicated to performing a function.

Detailed explanation-5: -Loose connective tissue works to hold organs in place and is made up of extracellular matrix and collagenous, elastic and reticular fibers. Dense connective tissue is what makes up tendons and ligaments and consist of a higher density of collagen fibers.
