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.
Answer:
Small intestine
Explanation:
Around eighty percent of usable nutrients are absorbed in the small intestine.
The main area of gastrointestinal tract responsible for absorption is small intestine. It consists of three sections, i.e. the duodenum, jejunum and ileum. In duodenum, jejunum majority of nutrients are absorbed.
The duodenum absorbs carbohydrates, proteins, and starches that are in the form of glucose or proteins are absorbed in the jejunum.
