Describe the mechanics of inspiration. • The rate of inspiration and expiration is controlled by the respiratory center in the medulla oblongata. • Inspiration occurs due to ↑ firing of inspiratory nerves and so the ↑ recruitment of motor units within the intercostals and diaphragm. • Inspiration is the process of inhaling oxygen. When we breathe in, the diaphragm contracts and moves downward. This ↑ the space in the chest cavity into which our lungs expand. Thus, the intercos...

What kind of shock is associated with SIRS? Septic shock What is cardiac output like with septic shock? Normal/high What happens with SIRS? Insult --> Huge outpouring of INFLAMMATORY mediators --> VASODILATION/ vascular leakage / venous blood pooling --> HYPOperfusion / cell hypoxia / metabolic derangements --> Organ dysfunction --> Organ failure or DEATH

Which node has the highest intrinsic (automatic) rate? SA node pacemaker cells Groups of cardiac muscle cells with ability to spontaneously create action potential (automaticity) and comprise intrinsic conduction system SA node primary pacemaker cells located in wall of right atrium

Chromasia (meaning) color, the ratio of weight of hemoglobin to the volume of the red blood cell. Can be hypochromic: iron deficiency anemia, thalassemia normochromic (aplastic anemia, anemia of chronic renal failure) hyperchromic

Hyperkalemia an elevation of potassium ion concentration in the extracellular fluid Hyperkalemia - Etiology caused by factors that increase potassium intake, shift potassium from the cells into the extracellular fluid, and decrease potassium excretion. Hyperkalemia - Clinical Manifestations Intestinal cramping and diarrhea Skeletal muscle weakness Flaccid paralysis Cardiac dysrhythmias

frameshift mutation - ANSWER one or more bases are deleted or inserted, resulting in all downstream codons changing deletion - ANSWER loss of chromosomal material missense - ANSWER point mutation resulting in a codon for a different amino acid

cell injury caused by stress severe enough to impair function and ability of cell to adapt; may be reversible or irreversible depending on severity of stress and baseline condition of the cell; occurs prior to any biochemical and morphological signs of injury cellular adaptation vs cell injury cellular function is maintained during cellular adaption whereas cell injury results in impaired cellular function (reversible or irreversible)
