sickle cell disease
sickle-cell disease
It is biconcave in shape , mature red blood cell do not have nucleus,
The center of a red blood cell appears paler than the outer part because of how the cell is shaped. The red blood cell has a biconcave shape that is fat at the edges and flattened in the center, giving it a cross section that resembles a dumbbell.
Spectrin
Poikilocytosis is the medical term meaning any disorder of red blood cell morphology (shape). Examples include sickle-cell anemia and spherocytosis, among many others. Normal red blood cells are disk-shaped with two dents, one on each side. A poililocyte is any blood cell that doesn't have that shape.
Red blood cell count
It is a donut shape.
The red blood cell's biconcave shape increases its surface area for diffusion. The lack of a nucleus makes this shape possible.
A red blood cell when placed in salty solution shrinks and becomes wrinkled.
A red blood cell has no nucleus and a biconcave shape. This structure allows it to carry oxygen more efficiently.
A red blood cell contains a red pigment known as HAEMOGLOBIN.We know that haemoglobin is a protein.Its structure is quertenary which means its made up of coiled polypeptides.2 beta and 2 alpho.This therefore means the shape of a red blood cell is determined by quertenary structure of its red pigment.
