Correct Answer is B
Explanation
A. Subclavian duct: There is no specific "subclavian duct" for lymph drainage; lymphatic fluid drains into the subclavian veins.
B. Thoracic duct: The thoracic duct drains lymph from the lower limbs and the left side of the body, returning it to the circulatory system at the junction of the left subclavian and internal jugular veins.
C. Left lymphatic duct: The thoracic duct is often referred to as the left lymphatic duct but is not limited to just left drainage.
D. Right lymphatic duct: The right lymphatic duct drains lymph from the right upper quadrant of the body but does not drain lymph from the lower limbs.
Correct Answer is C
Explanation
A. It increases blood pressure, leading to a heart attack or stroke: This is not the primary mechanism of carbon monoxide poisoning.
B. It causes an increase in carbon dioxide, which causes an increase in pH: This is incorrect. Carbon monoxide binds to hemoglobin more tightly than oxygen, not carbon dioxide.
C. It occupies oxygen-binding sites on hemoglobin and decreases the amount of oxygen that reaches the tissues: Carbon monoxide has a high affinity for hemoglobin, leading to reduced oxygen transport in the blood, which can cause tissue hypoxia and death.
D. It causes inflammation within the bronchioles and prevents air from reaching the alveoli: This is incorrect; carbon monoxide poisoning does not work by causing inflammation.
