The pharynx assists in moistening and humidifying inhaled air? Answer; FALSE What is true of the intercalated discs? Answer: they allow cardiac muscle cells to share nutrients and electrica... l impulses The exposure rete of a pathogen determines the effectiveness of innate defenses? Answer: false What type of humoral immunity is generated when an individual receives an infection from another person? Answer: active natural humoral immunity What is NOT a benefit to the inflammatory process? Answer: initiates the production of T-cytotoxic cells What is true of polycythemia? Answer: it can be caused by cancer of the red bone marrow Cardiac output is measured by multiplying heart rate (per minute) by breathing rate (per minute)? Answer: false The right atrium and right ventricle will contract first then the left atrium and ventricle contract? Answer: false What is the secretion by the type II alveolar cells that prevent the lungs from collapsing between each breath by reducing surface tension? Answer; surfactant The nasal conchae assist in the filtering and moistening incoming air within the nasal cavity? Answer: true The thoracic and pulmonary volumes can both increase? Answer: true An abnormal clot formation within a blood vessel is referred to as: Answer: thrombus Type O blood is the universal recipient blood type? Answer: false What is true of gas exchange within the lungs? Answer: occurs through and with the type I alveolar cells Humoral immunity involves the production of antibodies that will attack any and all bacteria or viruses? Answer: false As the inspiratory muscles contract, the thoracic volume increases leading to an increase of pulmonary volume, which decreases the intrapulmonary pressure Answer: true What is NOT true of erythrocytes? Answer: their life span is about 3-4 weeks What is true of cellular immunity? Answer: Cytotoxic T cells are produced For expiration to occur, the intrapulmonary pressure has to: Answer: increase compared to atmospheric pressure What is true of thrombocytopenia? Answer: it can lead to abnormal long bleeding times What is NOT true about the breathing process? Answer: for air to enter into the lungs, the atmospheric pressure has to be lower than intrapulmonary pressure What is NOT true of the hemostasis process? Answer: only the intrinsic pathway will convert prothrombin to the active form of thrombin What is the most numerous type of leukocyte? Answer: neutrophil What type of plasma protein plays a role within maintaining plasma osmotic pressure, blood pressure and is the most numerous? Answer: albumin Cardiac output is the amount of blood ejected from both ventricles with each contraction? Answer: false Antibodies are specific to one type of epitope? Answer: true What factor will not directly affect stroke volume? Answer: respiration rate What is NOT true regarding the heart valves? Answer: the right AV valve has only two cusps What is NOT true regarding the larynx? Answer: the larynx is located posterior to the laryngopharynx and trachea What statement is NOT true of veins? Answer: they typically carry oxygenated blood What portion of the EKG wave pertains to the atria undergoing depolarization? Answer: P wave What is NOT true of the trachea? Answer: The respiratory cilia within the lumen move the mucus downward, toward the lungs This portion of the cardiac conduction system controls the rate at which the heart contracts? Answer: SA node The trachealis muscle is located on the posterior aspect of the trachea, facing the esophagus? Answer: true The right lung has two lobes? Answer: false Stroke volume is the measurement of Answer: the amount of blood that is ejected from a ventricle with each contraction The bronchial tree allows the passage of inspired air to reach the alveolar sacs for gas exchange to occur? Answer: true What anatomical structure ensures the heart valves only open and close in one direction? Answer: chordae tendinae What term best describes the amount of air expelled from the lungs after a maximum inspiratory effort? Answer: vital capacity Coagulation is the final step in the hemostasis process? Answer: true T Helper cells are involved in cellular and humoral immunity activity? Answer: true The primary role of the smooth muscle surrounding the bronchi is to provide structural support? Answer: false Increased heart rate will increase the overall cardiac output? Answer: true What portion of the EKG wave pertains ventricles contracting during the cardiac cycle? Answer: QRS complex What is NOT a role of the nasal cavity? Answer: concentrate the oxygen of incoming air Only arteries undergo vasoconstriction and vasodilation? Answer: true Oxygen and carbon dioxide gas exchange in the lungs occurs due to Answer: diffusion The right atrium Answer: receives blood from the body circuit Arterioles are the smallest form of an artery and is where gas exchange occurs? Answer: false What is the correct pathway of the cardiac conduction system? Answer: SA node-AV bundle of His-Right/Left bundle branches- purkinje fibers What statement is true of capillaries? Answer: they allow for nutrient and gas exchange within the body What is NOT true of the pleura of the lungs? Answer: the pleura covers the internal surfaces of the alveolar sacs What is NOT true regarding inflammation? Answer: it stimulates a fever to develop Anemia is classified and defined as the body being iron deficient? Answer: false The left ventricle Answer: pumps blood to the body circuit What term best describes the normal amount of air that I brought into and out of the lungs during quiet or resting breathing? Answer: tidal volume The visceral pleura is found attached to the inner surface of the ribs? Answer: false What muscle is NOT considered a respiratory muscle? Answer: pectoralis major muscle The pulmonary arteries contain deoxygenated blood? Answer: true For inspiration to occur, intrapulmonary pressure must be higher than atmospheric pressure? Answer: false [Show More]
