TAKE TIME TO WRITE AN INTRODUCTION AND SUMMARY. The introduction will consist of the main point to be made; the summary is simply a paraphrasing of the introduction. A neat bundle with a beginning and ending is very satisfying to the reader. Be sure that your answer is direct and really answers the question.
The spleen is located in the upper left abdominal cavity, just beneath the diaphragm, and posterior to the stomach. It is similar to a lymph node in shape and structure but it is much larger. The spleen is the largest lymphatic organ in the body. Surrounded by a connective tissue capsule, which extends inward to divide the organ into lobules, the spleen consists of two types of tissue called white pulp and red pulp. The white pulp is lymphatic tissue consisting mainly of lymphocytes around arteries.
A sample of tissue removed for examination under a microscope (biopsy) contains many types of cells, even though a doctor may be interested in only one specific type. Connective tissue is the tough, often fibrous tissue that binds the body's structures together and provides support and elasticity. It is present in almost every organ, forming a large part of skin, tendons, joints, ligaments, blood vessels, and muscles.
