Question

at is true about the hormone that is released from the organ at the tip of the ck arrow? it decreases body temperature (to a normal body temperature) it increases bmr (basal metabolic rate)

Explanation:

The organ at the tip of the black arrow (pointing to the thyroid) has the blue organ (parathyroid or maybe pituitary? Wait, the tip of the black arrow's organ—wait, the black arrow is on the thyroid, the tip arrow (small black arrow) is on the structure above thyroid, likely the pituitary? No, the structure above thyroid is the larynx? Wait, no, the blue structure is the thyroid's upper part? Wait, actually, the organ at the tip of the small black arrow (the blue one, maybe the pituitary? No, the pituitary is in the brain. Wait, maybe the blue organ is the parathyroid? No, the thyroid is the pink one. Wait, the question is about the hormone from the organ at the tip of the small black arrow (the blue structure, maybe the pituitary? No, the pituitary is not there. Wait, maybe the blue structure is the thyroid's isthmus? No, the thyroid is the pink gland. Wait, the small black arrow is pointing to the structure above the thyroid, maybe the larynx? No, the hormone from the thyroid: wait, the black arrow is on the thyroid, the small arrow is on the structure above (maybe the pituitary? No, the pituitary is in the brain. Wait, perhaps the organ at the tip of the small black arrow is the pituitary, but no, the pituitary is in the skull. Wait, maybe the blue organ is the thyroid's upper lobe? No, the thyroid is the pink gland. Wait, the hormone from the thyroid (the organ the black arrow points to) or the organ at the tip of the small arrow. Wait, the small arrow is on the blue structure, which is above the thyroid. Wait, maybe the blue structure is the parathyroid? No, parathyroid is on the thyroid. Wait, perhaps the organ at the tip of the small black arrow is the pituitary, but that's not there. Wait, maybe the question is about the thyroid hormone. Wait, the options: "It increases BMR (basal metabolic rate)" is a function of thyroid hormone (T3/T4). The other option: "It decreases body temperature"—thyroid hormone increases metabolic rate, which increases body temperature, so that's wrong. Wait, maybe the organ at the tip of the small arrow is the pituitary, but no. Wait, the black arrow is on the thyroid (pink gland), the small arrow is on the blue structure (maybe the pituitary? No, the pituitary is in the brain. Wait, maybe the blue structure is the thyroid's upper part, and the hormone from the thyroid (the organ the black arrow points to) has the function of increasing BMR. So the correct option is "It increases BMR (basal metabolic rate)". Wait, the options: one is "It decreases body temperature" (wrong, thyroid hormone increases metabolic rate, which increases heat production, so to normalize temperature? No, if body temperature is high, but thyroid hormone increases BMR, which increases temperature. Wait, maybe the organ at the tip of the small arrow is the pituitary, which releases TSH (thyroid - stimulating hormone) to stimulate thyroid. But the hormone from the thyroid (TSH - stimulated) increases BMR. So the correct option is the one about increasing BMR.

Answer:

It increases BMR (basal metabolic rate)
