Complete question: find the structure in the attached file below.
The correct options that are NOT the function of the highlighted structure of the eye are A, C and D.
The eye is a sensitive organ of the body used for visual purposes. It is made up of different parts and structures which includes:.

-Internal structures:Lens,Retina,Optic nerve
Aqueous Humour and Vitreous Humour.
The highlighted structure from the diaphragm is the external structure called the IRIS. The iris is the pigmented part if the eye that allows a certain amount of light to enter the eye through the iris dilator muscles.When the iris dilator muscle cells are stimulated, the cells contract, widening the pupil and allowing more light to enter the eye. I hope this helps, thanks.

The correct answer will be the right chamber of the heart especially right ventricle.
Pulmonary hypertension is the elevated blood pressure in the arteries of the lungs known as pulmonary arterioles. This happens due to the narrowing of the pulmonary arterioles in the lungs and capillaries which could lead to the blockage of arterioles.
This increases pressure in the arterioles and alveolar part of the lungs which is passed down to the right part of the heart especially "right ventricle" which pump deoxygenated blood to the lungs through the pulmonary artery. The right ventricle has to work harder to pump blood to lungs which causes the heart muscle to weaken and fail.
Thus, the right chamber of the heart especially right ventricle is the correct answer.
