Define primary prevention and give an example: Your Answer:
Primary prevention is prevention that is making someone aware of the disease and how to prevent it. For example, DARE is a program to help enlighten the effects of drugs if you were to take them. The goal of primary prevention is to remove risk factors to prevent disease from occurring. Examples include taking folic acid while pregnant to prevent neural tube defects, vaccinating children to prevent communicable disease, eating healthy and exercising to prevent heart disease, and wearing seatbelts or helmets. Apoptosis is programmed cell death. This process eliminates cells that are worn out, have been produced in excess, have developed improperly, or have genetic damage. Apoptosis is also responsible for several normal physiologic processes, like replacing cell in the intestinal villi and removing aging red blood cells. Your Answer: Explain apoptosis and why it is necessary:
Explain what necrosis is and give an example and description of one type of necrosis.
Correct! Radiation treatment Correct! Lead toxicity a. Physical agents b. Radiation injury c. Chemical injury
Epithelial tissue covers the body’s outer surface, lines the inner surfaces, and forms glandular tissue. Epithelial tissue has three distinct surfaces and the basal surface is attached to an underlying basement membrane. It is avascular, meaning without blood vessels. It receives oxygen and nutrients from the capillaries of the connective tissue on which it rests. Connective or supportive tissue is the most abundant tissue in the body. It connects and binds or supports the various tissues. Its cells produce the extracellular matrix that support and hold tissues together. Connective tissue is divided into two types: connective tissue proper and specialized connective tissue (cartilage, bone, and blood cells). The four types of connective tissue proper are loose (areolar), adipose, reticular, and dense connective tissue. The function of muscle tissue is to move the skeletal structures, pump blood through the heart, and contract the blood vessels and visceral organs. Muscle tissue can accomplish this by contraction. The two types of fibers that contract are called thin and thick filaments. Thin filaments are called actin, and the thick filaments are myosin. The three types of muscles tissue are skeletal, cardiac, and smooth. Nervous tissue is distributed throughout the body for communication. It provides the means for controlling body function and for sensing and moving about the environment. The two types of cells are neuron and glial cells. Neurons function is communication. Glial (meaning glue) cells support the neurons.
