the primary function of the lungs : Host Defense&Gas exchange Optimal gas exchange requires: : Intact nervous system, .Compliant lungs, Work of breathing, Hemodynamic/Cardiac Function Respiratory process has three distinct concepts: : VENTILATION, RESPIRATION, PERFUSION Inspiration: : Thorax enlarges and the intrapulmonary pressure decreases below atmospheric pressure. If the intrapulmonary pressure drops below that of the atmosphere, air enters the lung Expiration: 2 | P a g e ...

Bio 106 WSU Carloye Exam #4 What is the difference between blood and hemolymph? - Blood: In a Closed circulatory system and is confined to vessels. Hemolymph (AKA interstitial fluid): In an Open circulatory system and bathes the body cells. What are the major types of blood cells? - red and white cells What adaptations allow an animal to use diffusion across its skin as the only mechanism for gas exchange? - The animal must be thin and have a large surface area.

AMI AMI (Heart attack): Death of heart muscle following obstruction of blood flow to it; in this context the attack is "new" or "happening right now." A heart attack is a medical emergency. A heart attack usually occurs when a blood clot blocks blood flow to the heart. Without blood, tissue loses oxygen and dies. Symptoms include tightness or pain in the chest, neck, back, or arms, as well as fatigue, lightheadedness, abnormal heartbeat, and anxiety. Women are more likely to have atypi...

Define the terms hypoxemia and hypercapnia and compare the manifestations of each. hypoxemia: when arterial PaO2 is <95. hypercapnia: increased CO2 in blood. PaCO2 is greater than 45. Differentiate between the mechanisms causing disorders of ventilation and diffusion. Disorders of ventilation affect how air move in and out of the lung. Disorders of diffusion affect how gasses move between the alveoli and pulmonary capillaries. Characterize the pathogenesis and manifestations of transudative...
