- A patient is hyperventilating, and suddenlyfeels ill. Which of the following are ways thebody will attempt to maintain homeostasis? (check all that apply) A. Activity will increase at thepneumotaxic center to increase the rateof breathing. B. The person will vomit to removeexcess acid in their system. C. The peripheral chemoreceptors willdetect the level of oxyhemoglobinpresent in the blood .D. The kidneys will secrete more bicarbonate ionsWhich of the following carries oxygento various parts of human body?A. Red blood cellsB. White blood cellsC. PlasmaD. NervesEven though the body's organ systems are grouped separately, they are not independent of each other. Explain how a bad cold, which affects your respiratory system, can keep you from studying well for a major examination.
- Opiates, alcohol, barbiturates, and other depressants are potentially dangerous since there is the risk ofinhibiting __________.A.digestionB.respirationC.the vomiting reflexD.blood pressueThese microscopic air sacs in your lungs are where the blood picks up oxygen to return it to the heart: A) AlveoliB) Bronchial TubesC) CapillariesD) VentriclesWhich of the following structures separates the lunginto lobes?a. mediastinumb. fissurec. rootd. pleura
- Gas exchange that occurs at the level of the tissues iscalled ________.a. external respirationb. interpulmonary respirationc. internal respirationd. pulmonary ventilationThe nature of the sounds produced by percussion (tapping) of a patient’s chest can tell a physician a great deal about the condition of the organs within the thoracic cavity. Healthy, air-filled lungsresonate, or sound hollow. How do you think the lungs of a person with emphysema would sound in comparison to healthy lungs? What kind of sounds would be produced by a collapsed lung, or one thatwas partially filled with fluid?Although the body’s organ systems are grouped separately, they are not independent of each other.

- The “bends” or decompression sickness is a formof air embolism. When scuba or deep sea diversare under higher pressure, more nitrogen gasdissolves in the blood and tissue fluids. Usually aslow ascent to the surface (lower pressure) allowsthe gas to be gradually dissipated and exhaled. Ifa diver rises to the surface too rapidly, the gascomes out of solution, forming bubbles or gasemboli in the circulation. Explain why ischemiaand pain may occur in various tissues such asmuscle, joints, or the heart.The structures in the passageways of the lung which become paralyzed in the early stages of chronic bronchitis so they cannot sweep out contaminants are the: A. Cilia B. Helper T's C. capillaries D. alveoliblood ph varies between 7.35 and 7.45, with a target value of 7.4. if someone's blood ph begins to decrease, chemoreceptors detect this change and send the information to the brain the brain analyzes the input and sends out a command to the respiratory muscles causing breathing rate to increases, which reduces carbon dioxide levels and thereby increases the ph of ther blood. name the body part, values, or actions in this specific scenario involving ph Normal range Set point Stimulus Sensor integrsting center Effector Response
