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 ions
Evolution Connection Lizards and snakes cannotbreathe while chewing food because the connection betweentheir external nostrils and their esophagus is in the mouth.In contrast, mammals can continue breathing throughthe nostrils while chewing food in the mouth. However,choking sometimes occurs when the paths of air and foodcross each other. Thinking about the high oxygen demandof active endotherms, explain how the concept of descentwith modification explains this “imperfect” anatomy of someamniotes (see Figure 34.2 to review vertebrate phylogeny).
Alveoli is related to which of thefollowing system of human body?A. Circulatory systemB. Excretory systemC. Reproductive systemD. Respiratory system
*Respiratory SystemThe respiratory system functions in the exchange of gases between the external and internalenvironments. Major parts of the system include the nasal cavity, larynx, trachea, bronchi, and pulmonaryalveoli. Some regions of the respiratory system are specialized for the conduction of gases and other areasfunction primarily in the exchange of gases. Filtration mechanisms exist in both regions. The function ofeach part of the respiratory system is reflected in the structure of its wall: the type of epithelium and itsapical modifications, intraepithelial and subepithelial glands, cartilaginous rings and plates, smoothmuscle and elastic tissue, and the relationship of capillary endothelium to alveolar epithelium.Study the Respiratory system in Slide Box and Respiratory system under EM. QUESTION: What is the distinctive structural component of the wall of the trachea?

QUESTION: What does the EM demonstrate regarding the air-blood barrier?
Air is pulled into the human respiratory tract mainly because ofvolume changes in thea. nose. c. chest cavity.b. pharynx. d. trachea.
The 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?
A broken rib can sometimes puncture a lung, causing it to collapse. Acollapsed lung leaks air into the chest cavity. Why might it be difficultfor a person to fully expand a collapsed lung?
Daniel, the swimmer with the fastest time on the college swim team, routinely hyperventilates before a meet, as he says "to sock some more oxygen into my lungs so I can swim longer without having to breathe." "Furthermore, my heart won't have to adjust it's output". Which organ(s) would actually require more oxygen that Daniel may not be realizing? Why so?
Death by drowning can occur in either of two ways, by theairways filling with water (more common), or a reflexlaryngospasm (strong muscle contraction of the larynxclosing it). Explain how each mechanism causes death.
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.
A section of the lung that receives its own tertiary bronchus is called the ________. bronchopulmonary segment pulmonary lob tile interpulmonary segment respiratory segment
