<span>The
correct answer is orthoptics.</span>
<span>Orthoptics is a profession of eye care that do things such as
diagnosis and non-surgical management of strabismus (wandering eye), amblyopia
(lazy eye) and eye movement disorders. Orthoptists are trained professionals
who are uniquely skilled in diagnostic techniques.</span>
Explanation:
- One of the main differences between adult and fetal circulation is <em>the direction and where the non-oxygenated and oxygenated blood circulates</em>. In adults arteries carry oxygenated blood away from the heart and veins carry non-oxygenated blood towards the heart; in fetuses, arteries carry non-oxygenated blood away from the heart and veins carry oxygenated blood back to the heart.
- Another difference is <em>where does the exchange of gases takes place</em>, in fetuses blood is oxygenated in the placenta, in adults in the lungs.
- The circulation between adults and fetuses differs in <em>where does the pressure increases</em>, in adults is on the left side of the heart, in fetuses on the right side.
- Finally,<em> another important difference between adults and fetuses is the presence of shunts</em>, in fetuses these shunts allow both sides of the heart to work parallelly letting mix blood from both ventricles. This shunt gets closed after birth, so adults do not have them.

<span>Blood supplies oxygen to cells to perform cellular respiration. Haemoglobin carries oxygen in the blood.Any change in the structure of hemoglobin will affect its oxygen carrying capacity. Mutation of genes coding for hemoglobin will result in a different hemoglobin which will fail to supply oxygen properly. Hence patients needs blood transfusion to maintain oxygen supply.</span>
