Introduction: Hemorrhage refers to the loss of blood from the circulatory system caused by the damage in the blood vessels. Various homeostasis mechanisms of the body help in the restoration of blood pressure following a hemorrhage.
Answer to Problem 1TY
Correct answer: The respiratory system helps to increase the return of the blood from veins to the heart. Hence, the correct answer is option b.
Explanation of Solution
Reason for correct answer:
The respiratory system helps in increasing the alveolar volume. It results in the faster oxygenation of blood. The increase in the breathing rate also helps in the faster exchange of oxygen and increase the return of oxygenated blood by pulmonary vein to the heart by pulmonary vein. Hence, the respiratory system manages homeostasis by increasing the flow of oxygenated blood to the heart.
Option b is given as “by helping to increase the return of blood from veins to the heart”.
The respiratory system helps in maintaining blood pressure after a hemorrhage by increasing the amount of blood transfer through veins towards the heart. Hence, the correct answer is option b.
Reasons for the incorrect answer:
Option a. is given as, “by increasing the saturation of hemoglobin with oxygen”.
The oxygen saturation does not increase by the respiratory system, but it is dependent on the external factors like temperature or pressure change. Hence, option a. is incorrect.
Option c. is given as, “by increasing the heart rate”.
The increase in the heart rate is independent of the respiratory system. The heart rate depends upon various factors, like blood pressure, for increase or decrease of heart rate. Hence, option c. is incorrect.
Option d is given as, “by activating the baroreceptor reflex”.
The baroreceptor reflex is activated due to change in the blood pressure. This reflex is not affected by the respiratory system. Hence, option d. is incorrect.
Option e. is given as, “through the Bohr effect”.
Bohr Effect is the effect of the presence of carbon dioxide and hydrogen ion on the value of the oxygen dissociation curve. However, the respiratory system does not influence the oxygen dissociation curve. The oxygen dissociation curve depends upon the temperature, pressure, and other factors. Hence, option e. is incorrect.
Hence, the options a., c., d., and e. are incorrect.
The respiratory system helps to increase the amount of blood to the heart by increasing pulmonary respiration.

Is the phenotype going to be that there is a disruption of the formation of the neural tube for both of these because bottle cell formation is necessary for the neural plate to fold in forming the neural tube and Shroom3 is further needed to close the neural plate? So since both Plekhg5 and Shroom3 are used in forming the neural tube, injecting the mRNA will just lead to neural tube deformity?arrow_forward
