write down the structure of red blood cells
Answers
Answer:
The cell is flexible and assumes a bell shape as it passes through extremely small blood vessels. It is covered with a membrane composed of lipids and proteins, lacks a nucleus, and contains hemoglobin—a red iron-rich protein that binds oxygen.
Answer:
Erythrocytes have a consistent diameter of 7-8 µm, making them the perfect ‘histologic rulers’ during routine examinations. However, they have an atypical structure compared to the majority of human body cells. First of all, erythrocytes have a biconcave shape, which resembles a donut. This means that their periphery is thicker than their central part. This feature maximizes the total surface of the cell membrane, facilitating gas exchange and transport. In addition, erythrocytes do not have a nucleus (anuclear) or any other intracellular organelles, as they are all lost during erythropoiesis. The only two major structures left are the cytoplasm which is enclosed by a surrounding cell membrane.
