PATHO 370 MIDTERM EXAM REVIEW 2023 COMPLETE. PATHO 370 Pathophysiology Homeostasis and Adaptive Responses to Stressors Homeostasis- state of equilibrium Allostasis- Ability to successfully adapt to changes Stress: a state manifested by a specific syndrome of the body developed in response to any stimuli that made an intense demand on it. Influenced by genetics, socioeconomic status, prior susceptibilities, pre-existing health status, allostatic state and ability to manage stress General A...

1. Ischemia and other toxic injuries increase the accumulation of intracellular calcium as a result of: A) release of stored calcium from the mitochondria. B) improved intracellular volume regulation. C) decreased influx across the cell membrane. D) attraction of calcium to fatty infiltrates. 2. The patient is found to have liver disease, resulting in the removal of a lobe of his liver. Adaptation to the reduced size of the liver leads to _ of the remaining liver cells. A) metaplasia B)...

Applied Pathophysiology A Conceptual Approach to the Mechanisms of Disease 3rd Edition Braun Test Bank Chapter 1Introduction to Pathophysiology 1. The nucleus , which is essential for function and survival of the cell. A) is the site of protein synthesis B) contains the genetic code C) transforms cellular energy D) initiates aerobic metabolism 2. Although energy is not made in mitochondria, they are known as the power plants of the cell because they: A) contain RNA for protein syn...

Week Topics 1 • Developmental changes Review Kennedy and Dunphy readings for age related changes Replicative senescence is theory states that cells can replicate or divide a specific number of ti mes. This ability tends to decrease with age. Oxidative damage is the cumulative result of the aerobic metabolism, which generates chemicals called free radicals. Free radicals may interact with other chemicals in the body and cause damage to cells. Telomere shortening is a theory that links aging to ...

PATHO 370 MIDTERM EXAM REVIEW 2023 COMPLETE. Pathophysiology. Acute versus Chronic Stress: • Acute stress: associated with the ANS, the fight or flight response; persons with preexisting heart disease can have complications with acute stress response that can lead to arrhythmias; in healthy individuals acute stress response can redirect attention from behaviors that promote health and interrupt compliance with medication regiments & exercise programs • Chronic stress: it has been linke...
