When muscle cells are very active during exercise, they use more ATP energy.Explain how this is related to increased breathing rate and depth (taking moreand deeper breaths) both during exercise and for some time after you finishexercising. Be specific about the cellular respiration processes, inputs, andoutputs occurring in the cells that cause your body to respond with a changein breathing.
Your alveoli are adapted to speed up the diffusion of gases. Of the following options, choose the ones that SPEED UP diffusions. O Small Surface Area O Small Concentration Gradient O Large Surface Area O Thick Walls O Thin Walls O Large Concentration Gradient
Watch this video (http://openstaxcollege.org/l/oxyblood) to see the transport of oxygen from the lungs tothe tissues. Why is oxygenated blood bright red, whereasdeoxygenated blood tends to be more of a purple color?
Oxygen and carbon dioxide diffuse across our respiratory surface into and out of the blood via simple diffusion. The respiratory membrane is thin so gases diffuse only a short distance through the liquid and into the blood. Fluid buildup in the lungs increases the distance through the liquid medium. How does this impact the concentration of oxygen in the blood? Explain.
Trace the pathway of oxygen using the “Bunch of Grapes “model. Notethat air moves from the nose (nasal cavity), and mouth (oral cavity) to thetrachea, bronchi, bronchioles, and then into the alveoli (air sacs). Theair we breathe carries the gas oxygen. When we breathe, the oxygengoes to the lungs
Cartilage has primary function to: keeps the windpipe open all the time increase the surface area connect to esophagus protects the trachea Which of the following best describes diastole?
The hemoglobin in mammalian blood is usually thought ofsimply as increasing the amount of O2 that can be carried by eachliter of blood. However, in a lecture on hemoglobin, a respiratoryphysiologist made the following statement: “The presence ofhemoglobin in the blood also makes possible the rapid uptakeof O2 by the blood as it flows through the lungs.” Explain thelecturer’s point.
In the trachea, mucus secreted by _____cells traps foreign particles which are then swept away by tiny _______ on the surface of epithelial cells.
As a scuba diver descends, the pressure of the water on the bodyprevents normal expansion of the lungs. To compensate, the diverbreathes pressurized air, which has a greater pressure than air at sealevel. What effect does the increased pressure have on the amount ofgas dissolved in the diver’s body fluids? A scuba diver who suddenlyascends to the surface from a great depth can develop decompressionsickness (the bends), in which bubbles of nitrogen gas form. Theexpanding bubbles damage tissues or block blood flow through smallblood vessels. Explain why the bubbles develop.
A small ridge of cartilage at the most inferior portion of the "windpipe" called the __________ now directs some air towards the left lung and some towards the right lung. The air will now travel through a series of tubes that become smaller and smaller as they repeatedly branch; these tubes, very similar in structure to the "windpipe", are called __________. Even tinier tubes continue branching; these tubes contain…
One technique for artificial respiration is mouth-to-mouth resuscitation. The rescuer takes a deep breath, blows air into the patient’smouth, and then lets air flow out. The process is repeated. Explain thefollowing: (1) Why do the patient’s lungs expand? (2) Why does airmove out of the patient’s lungs? (3) What effect do the Po2 and thePco2 of the rescuer’s air have on the victim?
