Which statement about the regulation of respiration is FALSE? Group of answer choices Respiratory centers in the medulla control the transition from inspiration to expiration. Carbon dioxide concentration is the most important chemical stimulus for regulating respiratory rate. Chemoreceptors in the walls of various arteries are sensitive to carbon dioxide levels in the blood. A group of neurons in the ventral medulla only become active when we need to breathe forcefully. Chemoreceptors may be sensitive to oxygen, carbon dioxide, and/or hydrogen ion concentration.
As the diaphragm contracts, the rib cage expands and the lungs fill with air. This is an inhalation true or false
during mouth to mouth resuscitation, air is forced into the victims trachea. Exhaled air contains a high level of CO2 than the atmospheric air. Would the higher level of CO2 create problems for the victim or would the exhaled air be beneficial?
The human respiratory system functions in the following ways. Explain each: gas exchange sense of smell voice production body defenses acid-base balance temperature regulation
Match the description below with the proper function. Forced breathing [ Choose ] [Choose ] requires only diaphragm and intercostal muscles how gas exchange occurs Space on right lung to provide room for the heart space on left lung to provide room for the heart requires multiple muscle contractions controls breathing by contraction and relaxation Diaphragm Cardiac notch Diffusion [ Choose ]
Which structure is involved in gas exchange? Multiple Choice Trachea Bronchus Alveolus Terminal bronchiole
What prevents overinflation of the lungs? partial pressure of oxygen in alveoli baroreceptors in aortic arch stretch receptors in the lungs the hypothalamus
Put the following in order by numbering from 1 to 5 - Diaphragm contracts and flattens and ribs elevate - The diaphragm returns to its dome shape resting position - The thoracic cavity increases in volume - Air inters the lungs due to a lower pressure gradient than atmospheric pressure - A subatmospheric pressure is created in the lungs
Air flow into and out of a blind cavity is which type of ventilation? Group of answer choices Unidirectional Flow Tidal Flow Concurrent Flow Cross Current Flow
Which of the following is an example of the respiratory and circulatory systems working together? The blood flows through the kidneys, and waste products are removed. The lungs take in air, and the blood carries oxygen to the body's cells. O The diaphragm flexes, and the lungs take in air. OThese two systems do not work together.
Which of the following explain the effect on the body if a patient has a low level of oxygen in their arterial blood? 1 cardiac output increases 2 The patient will breathe in a larger volume of air each minute 3 The pulmonary artery will dilate 4 The patient will experience feelings of restlessness and headaches 1, 2, 3 and 4 are correct 1, 2, and 4 are correct
Which of the following would you expect to find in the pulmonary system? An overall higher concentration of oxygen in the pulmonary arteries A similar concentration of oxygen and carbon dioxide as in the rest of the body An overall higher concentration of oxygen in the pulmonary veins An overall higher concentration of carbon dioxide in the veins
