None of these. You want to limit stress.
In medical sciences, the movement of solid particles (solute) from an area of greater to lesser concentration is called by DIFFUSION.
A random passage of particles always occurs from a place of higher concentration to another of lower concentration. This happens until the distribution of the particles is uniform. From the moment the equilibrium is reached, as exchanges of substances between two media become proportional.
The passage of substances through cell membranes involves several mechanisms, among which we can mention:
✴ Passive transport (no loss of energy)
➡ Osmosis;
➡ Simple diffusion;
➡ Facilitated diffusion.
✴ Active transport (with loss of energy)
➡ Sodium and potassium pump
✴ Endocytosis and exocytosis
➡ Pinocytosis
➡ Phagocytosis

Answer:

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.
