Which of the following functions is associated with the nose?
A
Regulation of blood glucose levels
B
Detection of odor molecules (olfaction)
C
Production of digestive enzymes
D
Transmission of visual signals
Verified step by step guidance
1
Step 1: Begin by identifying the primary function of the nose in the human body. The nose is part of the respiratory system and plays a role in detecting odor molecules, which is known as olfaction.
Step 2: Eliminate options that are unrelated to the nose's function. For example, 'Regulation of blood glucose levels' is a function of the endocrine system, specifically the pancreas, and not the nose.
Step 3: Similarly, 'Production of digestive enzymes' is a function of the digestive system, primarily carried out by organs like the pancreas and stomach, and is not associated with the nose.
Step 4: 'Transmission of visual signals' is a function of the eyes and the optic nerve, which are part of the visual system, and not related to the nose.
Step 5: Conclude that the correct function associated with the nose is 'Detection of odor molecules (olfaction),' as this is the process by which the nose detects and interprets smells through specialized sensory cells in the olfactory epithelium.
