Question

when calcium levels in the blood are too low, the body releases a hormone that removes calcium from the bones. a person who suffers from a certain type of thyroid disease will often have low blood calcium and brittle bones because the body is taking the calcium from the bones. the afflicted person will typically see an endocrinologist, who studies hormones, and an orthopedist, who studies bones. what do these two doctors have in common? they both focus on hormone levels. they both focus on bone density. they both focus on calcium levels. they both focus on the thyroid.

Explanation:

El endocrinólogo estudia las hormonas que controlan los niveles de calcio en la sangre. El ortopedista estudia los huesos, donde el calcio se almacena y se libera cuando los niveles en la sangre son bajos. Ambos médicos se centran en el calcio: el endocrinólogo en su regulación hormonal y el ortopedista en su papel en la salud ósea.

Answer:

They both focus on calcium levels.
