Also known as erythrocytes, RBCs are the most common type of cell found in the blood, with each cubic millimeter of blood containing 4-6 million cells. With a diameter of only 6 µm, RBCs are small enough to squeeze through the smallest blood vessels.
Is RBC the smallest cell in human body?
Features. The Cerebellum’s Granule Cell is the smallest cell in the human body that is between 4 micrometres to 4.5 micrometres long. The RBC’s size also found roughly 5 micrometres. Most scientists suggest that sperm is the smallest cell in terms of volume.
Which cell type is the smallest?
Prokaryotes are the smallest types of cells, averaging 2-5μm in diameter. Despite their small size, inside each cell there is chemical and biochemical machinery necessary for growth, reproduction, and the acquisition and utilization of energy. The common features of prokaryotic cells are: cell wall.
Why is the RBC the smallest cell?
The RBC ‘s size also found roughly 5 micrometers. The largest cell is ovum in the human body.

Which blood cell is largest in size?
Monocytes are the largest cells of the blood (averaging 15–18 μm in diameter), and they make up about 7 percent of the leukocytes.
Which cell is the largest cell in human body?
The human egg (ovum) is the largest cell in the body and a nerve cell is the longest cell in the human body. The sperm is the smallest cell in human biology, but also one of the most complex.
Which is the longest cell?
– In the human body, the nerve cell is the longest cell. Nerve cells are also called neurons that are found in the nervous system. They can be up to 3 feet long.
Is the sperm the smallest cell?
The sperm is the smallest cell in human biology, but also one of the most complex. The egg meanwhile is the largest cell and similarly intricate.
What are the 2 types of cell?
Cell types. Cells are of two types: eukaryotic, which contain a nucleus, and prokaryotic, which do not. Prokaryotes are single-celled organisms, while eukaryotes can be either single-celled or multicellular.
What is the largest cell in the female body?
The ovum is one of the largest cells in the human body, typically visible to the naked eye without the aid of a microscope or other magnification device. The human ovum measures approximately 0.1 mm (0.0039 in) in diameter.
What is the smallest cell in the female body?
The ovum also called egg cell is the reproductive cell in the female body. Granule Cellof the Cerebellum is the smallest cell of the human body which is approximately 4 micrometer to 4.5 micrometer in size.
What is the shape of RBC?
The shape of the human red blood cell is known to be a biconcave disk. It is evident from a variety of theoretical work that known physical properties of the membrane, such as its bending energy and elasticity, can explain the red-blood-cell biconcave shape as well as other shapes that red blood cells assume.
What is the life span of RBC?
Human red blood cells are formed mainly in the bone marrow and are believed to have an average life span of approximately 120 days.
Which is the smallest WBC?
Monocytes are the largest type of WBCs while lymphocytes are smallest.
Which is the largest and smallest cell?
The longest cell is the nerve cell. The largest cell in the human body is female ovum. Smallest cell in the human body is male gametes, that is, sperm.
How do you identify blood cells?
The identification of blood cells is based primarily on observations of the presence or absence of a nucleus and cytoplasmic granules. Other helpful features are cell size, nuclear size and shape, chromatin appearance, and cytoplasmic staining.
