Chapter 23, Problem 20RAC
Summary Introduction
Introduction:
The respiratory system keeps blood oxygen and carbon dioxide concentration and blood pH within normal values. If any variation occurs in these levels beyond their normal range, there will be a significant effect on the relationship between hemoglobin, O2, and CO2.

Which of the following statements best describes the sensory inputs to the respiratory centres? Central chemoreceptors located on the carotid bodies in the neck monitor arterial blood chemistry. Peripheral chemoreceptors detect an increase in the partial carbon dioxide pressure resulting in stimulation of the respiratory centres. Stretch receptors in the brainstem are activated when the lungs expand. Peripheral chemoreceptors monitor the chemistry of the cerebrospinal fluid to detect changes in pH.arrow_forward

- 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.arrow_forwardcan you explain this question in terms of chemoreceptors?arrow_forwardChoose from the following to fill: Medulla oblongata, CO2 and H +, diaphragm, intercostal muscles, contract, up and out, down, increase, negative, into, stretch receptor in the alveoli, down and in, up, decrease, positive, out of, hypothalamus, CO2 and O2, O2 and H+, abdominal muscles, stretch receptor in the medulla oblongata.arrow_forward
