The four important characteristics of respiratory surface are:
1. Thin walls
2. Moisture
3. Large surface area
4. Blood supply
Respiratory system or respiratory tract is divided into upper and lower tract. Upper respiratory tract includes nose and its cavities, sinuses, pharynx and the part of the larynx. Lower respiratory tract consists of the trachea, bronchi, bronchioles and the alveoli.
Alveoli are the ends of the respiratory tract the smallest units in it. Alveoli are small folded air sacs that are branching off from alveolar ducts and providing an extremely large surface area for the gas exchange. Gas exchange occurs thanks to small blood vessels – capillaries that surround alveoli and it occurs via the process of diffusion.
So, respiratory surface is thin membrane also known as the blood–air barrier that consists of the alveolar epithelial cells, their basement membranes and the endothelial cells of the alveolar capillaries.

The correct answer is option (A) Chlamydia.
A typical sexually transmitted illness is chlamydia. Both men and women are susceptible. However, compared to men, women are typically more negatively impacted by its consequences.
Symptoms and reasons for Chlamydia

- Some signs, such vaginal ulcers, are difficult to see, making the infected unaware that they have the disease.
- If addressed, this can result in even more serious issues including pelvic inflammatory disease, which then might have an impact on fertility.
- It may harm a woman's reproductive system permanently. Later it becomes challenging for women to get pregnant as a result. Additionally, chlamydia can result in an ectopic pregnancy that may be fatal.
