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. Your Answer: Necrosis is the cell death of an organ or tissue that is part of a living person. coagulative necrosis is an example. It happens due to a sudden cutoff of blood supply to an organ, such as the heart. Question 17 10 / 10 pts Match the type of cell injury to the cause. Some answers may be used more than once. (1 point each) Necrosis refers to cell death in an organ or tissues that is still part of a living person. It often interferes with cell replacement and tissue regeneration. Coagulative necrosis results most often from a sudden cutoff of blood supply to an organ (ischemia), particularly the heart and kidney. Liquefactive necrosis occurs when some of the cells die but their catalytic enzymes are not destroyed. It is commonly seen with brain infarcts or abscesses. Caseous necrosis occurs as part of granulomatous inflammation and is most often associated with tuberculosis. Gangrenous necrosis most often affects the lower extremities or bowel and is secondary to vascular occlusion. The term gangrene is applied when a considerable mass of tissue undergoes necrosis. In dry gangrene the affected tissue becomes dry and shrinks, the skin wrinkles, and its color changes to dark brown or black. The spread of dry gangrene is slow. It results from a cut off in arterial blood supply and is a form of coagulation necrosis. In wet gangrene, the affected area is cold, swollen, and pulseless. The skin is moist, black, and under tension. Blebs form on the surface, liquefaction occurs, and a foul odor is caused by bacterial action. The spread of tissue damage is rapid. Correct!Correct! Bacteria Question 18 Not yet graded / 10 pts List the 4 types of tissue found in the body. Pick 2 and give a description and example of each. Your Answer: Epithelial, connective, muscle, nervous Epithelial tissue covers the entire body's outer layer as well as the inner surface. An example would be our skin. Muscle tissue's function is to move our bones and to pump blood supply through our heart. An example would be cardiac muscle tissue. 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. UnansweredUnanswered Question 19 Not yet graded / 2.5 pts What term means “cell eating” and engulfs and then kills microorganisms or other particulate matter? 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. Question 20 Not yet graded / 2.5 pts What is the term to describe when cells use energy to move ions against an electrical or chemical gradient? Your Answer: Active Transport Question 21 Not yet graded / 2.5 pts Give one function of a membrane potential: Your Answer: Generate nerve impulse Question 22 Not yet graded / 2.5 pts What is the diffusion of water called? Your Answer: facilitated diffusion Quiz Score: 37.5 out of 100
