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.

- The respiratory system_______. a. provides body tissues with oxygen b. provides body tissues with oxygen and carbon dioxide c. establishes how many breaths are taken per minute d. provides the body with carbon dioxidearrow_forwardWhat 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_forward
- 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_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_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_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_forwardDoes breathing rate affect lifespan in terms of oxidizing cells, metabolism etc. Or does a really low breathing rate just detriment brain development?arrow_forward
- When 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_forwardThe sequence of events that occurs as the breathing rate is increased is A) 5,3,1,2 and 4 B) 3,5,2,1 and 4 C) 3,2,4,1 and 5 D) 4,3,5,2 and 1arrow_forwardWhich of the following control breathing? select all that apply Centers in the Pons and Medulla control breathing Respiratory centers respond to changes in acid base Chemoreceptors respond to a decrease in oxygen Chemoreceptors are located in the heart and lungsarrow_forward
