Quiz 13: Your Body and How It Functions

Medicine

A tissue is made up of group of cells. These cells are similar in shape and function. Histology is the branch of biological sciences that deals with the study of tissue. Tissues may be hard, soft or liquid. For example, bones are hard tissues, muscles have soft tissues and blood is a form of liquid connective tissue. The four different types of tissues occurring in an individual have been discussed below: 1. Nerve tissue is present throughout the body. The function of nerve tissue is to send impulses to and from body organs through neurons. 2. Epithelial tissue forms the outer skin of the body. It forms a protective barrier as they are closely attached to each other. They are classified according to their shape and cell arrangement. By shape there are three types of tissue squamous, cuboidal and columnar and by cell arrangement- simple epithelium and stratified epithelium. 3. Connective tissue binds the cells and organs of the body together. Connective tissue is of 4 types namely; loose connective tissue, dense connective tissue, cartilage tissue and bone tissue. Functions of the connective tissue include binding, supporting, and connecting body tissues. It also functions in storing nutrients. Provide internal support to organs, protect organs, provide strength, and provide framework and strength for body. 4. Muscle tissue makes up the muscles of the body. There are three types of muscle tissues skeletal (throughout the body), cardiac (heart muscle) and smooth muscle tissues (internal organs).

In the given case study, a patient named Ms. Wilson looks confused when the doctor has confirmed that she is diagnosed with diabetes. After talking to her family, the physician got to know that her family usually calls diabetes as sugar. That is the reason behind the confusion of the patient. In the given situation, it is important to inform her about diabetes in detail. Diabetes is a disease, which occurs when the blood sugar or the blood glucose becomes too high. Blood sugar is regarded as the main source of energy, which comes from the diet consumed by the people. Insulin is classified as a hormone, which is produced by the pancreas. This hormone helps the glucose from the food to get into the cells as a source of energy. In the absence of the insulin, the glucose stays in the blood and does not reach to the cells of the body. This further results in the rise in the blood glucose level. Due to the inability of the body to produce or respond to the insulin results in the abnormally elevated level of glucose in the blood. Sugar is basically referred as the glucose in the body. That is the reason this disease also known as the sugar. In order to control the blood sugar level, the diabetes patients are required to follow a strict diet plan. It is also important to involve daily exercise in the routine as this will also aid in maintaining the levels of the blood glucose. The pancreas produces insulin, which lowers the blood glucose level. Hence, absence or insufficient amount of insulin in the body causes diabetes.

Communication is the best way to explain anything. The understanding of body system helps in many ways. If someone knows all the scientific terms, function, and diseases related to the body system, then those terms can be converted in an easy language. People will take interest automatically if they understand these terms. For example, there are people of different age group like child under 6, teenager and adult over 80. An individual wants to make them understand about how the muscles in the upper arm cause the forearm to move. First of all, make them understand the concept of the muscular system. Muscular system is comprised of muscles. In the body muscles helps in every possible movement of the body. They serve as the engine of the body. They turn energy into motion, which helps in body function and movement. Muscles are made up of elastic fibers. Elastic is a rubber like substance that can be stretched easily. These fibers contain filaments myosin and actin. Muscle contraction occurs when these fibers moves, like in a criss-cross pattern.
