Question

Is red blood cells(erythrocytes) considered true cells histologically? Why
why not? Explain it in long explanation​

Answer 1

Answer:

Although RBCs are considered cells, they lack a nucleus, nuclear DNA, and most organelles, including the endoplasmic reticulum and mitochondria. RBCs therefore cannot divide or replicate like other labile cells of the body. They also lack the components to express genes and synthesize proteins.

Explanation:

The Red blood cells are also called erythrocytes. RBCs store the haemoglobin, which is a respiratory pigment that binds to oxygen or carbon dioxide molecules. This helps in the transportation of the oxygen to different tissues and organs of the human body.

Answer 2

Answer:

Erythrocytes, or red blood cells (RBCs), have predictable dimensions which makes them a good “histologic ruler”.

Explanation:

Erythrocytes, or red blood cells (RBCs), have predictable dimensions which makes them a good “histologic ruler”. They are circular with a diameter of 7.8 micrometers. Erythrocytes are shaped like biconcave discs. At their perimeter they are 2.6 micrometers thick, at the center they are only 0.8 micrometers thick. This shape increases the cell's surface area to allow for more oxygen binding. Because these dimensions are typically consistent, leukocytes can be identified by comparing their size to that of the erythrocytes.

Hence we can conclude that RBC'S (erythrocytes) are considered true cells.
