Low mean corpuscular value can shift the curve to the left side.
Explanation:
RBC histogram may be defined as the process of plotting the number of blood cells on Y- axis and their relative size on X- axis. Modern automated haematology is used for the construction of RBC histogram.
The cell population of RBCs is similar in size but not equal to the size of RBC the curve can shift to either direction. The low MCV (mean corpuscular value) value can shift the the curve to the left side while considering an RBC histogram.
Our body contains miles of arteries and arterioles, yet these structures are nothing more than the vascular highways that provide a pathway for the blood. It's only when our blood reaches the tiny capillaries that nutrients and wastes can be exchanged. Capillaries are microscopic blood vessels that connect the arterioles with the venules. We'll discuss venules later in the lesson.
Capillaries are grouped together in capillary beds, which are simply a network of capillaries. Capillary beds are too small to see, but if you could see them, they would look like endless alleyways leading to virtually every tissue in our body. The rate of blood flow within a capillary bed is slow because there are so many different alleyways through which blood can travel. This slow speed limit, along with the very thin walls of the capillaries, means that capillary beds are an ideal place for the exchange of gases, nutrients, hormones, and wastes between the blood and tissue cells.
Hence, the right answer is option b "two capillary beds".
