Introduction: The process of gas exchange that occurs between an organism and its environment is known as respiration. For cellular respiration, most of the animal cells need a continuous oxygen supply. During respiration, oxygen is inhaled from the environment by animals and transported to individual cells of the body. As well as carbon dioxide produced by the cell during cellular respiration is exhaled from the body to the environment.

- What reactions enhance the transport of carbon dioxide throughout the body? How is carbon dioxide moved out of the body?arrow_forwardBreathing _______. a. ventilates the lungs b. draws air into airways c. expels air from airways d. causes reversals in pressure gradients e. all of the abovearrow_forwardConsider the following situation: You try to hold your breath for as long as you can, but you can do so only for about a minute voluntarily. Eventually, you can hold your breath no longer, and you start breathing involuntarily. Which parts of the brain are involved in the two actions? What is the physiologic process involved in the regulation of respiration?arrow_forward
- a)Some competitive swimmers hyperventilate before a race, thinking they can "load up extra oxygen" and hold their breaths longer underwater. While they can indeed hold their breaths longer, it is not for the reason they think. Furthermore, some have lost consciousness and drowned because of this practice. What is wrong with this thinking, and what accounts for the loss of consciousness? b) You cannot affect the oxygen delivery to your tissues by drinking "oxygenated water". However, breathing oxygen at hyperbaric pressures increases oxygen delivery to tissues. Explain why these two statements are true.arrow_forwardA premature baby delivered 48 hours ago, develops respiratory distress. The baby shows cyanosis and is breathing rapidly. What is the cause of respiratory distress in this baby? Why is surfactant needed? Consider the following situation: You try to hold your breath for as long as you can, but you can do so only for about a minute voluntarily. Eventually, you can hold your breath no longer, and you start breathing involuntarily. Which parts of the brain are involved in the two actions? What is the physiologic process involved in the regulation of respiration? . A client complains of severe pain during inspiration. His x-ray shows inflammation of the left lung pleura. What is the cause of the inflammation in the lung? A 40-year-old client visits the clinic for respiratory difficulty. He tells you that he has been a chain-smoker for the last 20 years. What information would you provide to such a client? Give reasons for your answer.arrow_forwardSome patients with severe emphysema have constant high levels of carbon dioxide because of inadequate ventilation. The central nervous system breathing center in these patients becomes insensitive to carbon dioxide and more dependent on the level of oxygen, which is low. These patients are said to have “oxygen-dependent respiratory drive". What might happen if you give such a person high levels of supplemental oxygen?

- Heart rate is controlled by the SA node, a patch of cells on the heart. Respiratory rate, on the other hand, is controlled by the respiratory center of the medulla oblongata. Why isn’t control of respiratory rate housed in the lungs themselves? (hint: think of muscles involved in each process.arrow_forwardWhich of the following is true of the regulation of breathing in humans? Select all that apply. Check All That Apply The concentration of oxygen in the blood is the primary regulator of breathing rate. Breathing can be controlled consciously but is usually subconsciously controlled by the brain. A compound that lowers blood pH would increase respiration rate. Increased levels of blood carbon dioxide lead to an increase in bicarbonate production, which buffers the blood, making it harde oxygen to enter tissues. Respiration increases with the increased production of carbon dioxide during exercise.arrow_forward1.) What was your recorded resting breathing rate (sitting position)? 2.) What was your breathing rate after exercise? 3.) How would you differentiate your breathing rates before and after exercising? 4.) When do you breath faster? Why do you think you breath faster during more vigorous activities? 5.) Other than exercise, what other factors do you think influence breath/ minute? Why?arrow_forward
- Which of the following statements regarding control of respiration is TRUE? At high altitude, a decrease in PC02 of the blood stimulates an increase in ventilation. An increase in the HCO3- concentration in blood stimulates ventilation. A slight decrease in arterial PO2 is a stronger stimulus for increased ventilation than is a comparable decrease in arterial PCO2. The most important signal for regulating ventilation is the H+ concentration of arterial blood. Increased concentrations of lactic acid stimulate ventilation primarily by acting on peripheral chemoreceptors.arrow_forwardDescribe the overall goal(s) of the respiratory and circulatory systems. Why are they considered to be linked to one another? a) Goal(s) of respiratory system: b) Goal(s) of circulatory system: Interdependence upon each other:arrow_forwardWhen a woman is very close to delivering a baby, she may hyperventilate. Breathing into a paper bag regulates her breathing. How does this action return her breathing to normal?arrow_forward
