Answer:
The correct answer will be option C- endothelial cells of the endocardium.
Explanation:
The pulmonary capillary bed is the network of capillaries in the lungs- alveolar region mainly where gaseous exchange takes place.
This bed receives blood from the pulmonary arteriole which arises from the pulmonary artery. The blood is pumped to this artery through the right ventricle of the heart. The right ventricle- especially the valves is lined from with the endocardium which lines it and prevents the blood from sticking to the inside of the chamber.
Therefore, the blood pumped from the right ventricle is in contact with the endothelial cells of the endocardium and option C is the correct answer.
Four bones of the skull contain paired air spaces called the paranasal sinuses that help to lighten the heavy load of the head.
<h3>What is Paranasal Sinus?</h3>
The paranasal sinuses are air-filled, bony spaces located next to the nasal passages in the face bones of the skull. They grow via slowly expanding pneumatized cells that erupt from the nasal cavity. The term is typically used in everyday speech to refer to the hollow, air-filled spaces in front of the human skull. There are four pairs of sinuses in humans. There are now eight sinuses in all. These four pairs of sinuses are together referred to as paranasal sinuses since they are all joined to the nasal cavity.
