- The second heaviest is liver which secretes bile.

What is the largest cell in the human body?
ovum
What is the largest cell in the female body?
Which is the longest cell?
Nerve cells
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.
Is egg a cell?
membrane and everything else inside is considered the cell, it can be said that it is a single cell. Then, the chicken egg deserves its reputation as the largest cell. If, however you consider the yolk and the albumen (the egg white), separate structures, then eggs are not a single cell.
Which bacteria has smallest cell?
Pelagibacter ubique. Pelagibacter ubique is one of the smallest known free-living bacteria, with a length of 370 to 890 nm and an average cell diameter of 120 to 200 nm. They also have the smallest free-living bacterium genome: 1.3 Mbp, 1354 protein genes, 35 RNA genes.
What is the smallest animal on earth today?
Kitti’s hog-nosed bat
What is the smallest virus?
MS2
Which is smallest bacteria or virus?
Viruses are tinier: the largest of them are smaller than the smallest bacteria. All they have is a protein coat and a core of genetic material, either RNA or DNA. Unlike bacteria, viruses can’t survive without a host.
Which is the biggest virus?
Comparison of largest known giant viruses
| Giant virus name | Genome Length | Capsid diameter (nm) |
|---|---|---|
| Megavirus chilensis | 1,259,197 | 440 |
| Mamavirus | 1,191,693 | 500 |
| Mimivirus | 1,181,549 | 500 |
| Tupanvirus | 1,500,000 | ≥450+550 |
Which is the biggest bacteria in the world?
Even visible to the naked eye, newly discovered bacteria named Thiomargarita namibiensis are the largest prokaryotic organisms yet known.
Is virus a germ?
A virus is the simplest of germs—it is nothing but genetic material encased in protein. Researchers debate whether a virus is even “alive.” By itself, a virus can accomplish nothing—it needs to enter a living thing to perform its only function, which is to replicate.
Does drinking alcohol kill viruses?
Consuming alcohol will not destroy the virus, and its consumption is likely to increase the health risks if a person becomes infected with the virus. Alcohol (at a concentration of at least 60% by volume) works as a disinfectant on your skin, but it has no such effect within your system when ingested.
How do viruses enter the human body?
In humans, viruses that cause disease like cold and flu are spread through bodily fluids, like spit or snot. The virus is so small that it leaves our bodies in these fluids, and can even float through the air in droplets from a sneeze or cough. The virus can enter the body through the eyes, nose, or mouth.
Do viruses have DNA?
Most viruses have either RNA or DNA as their genetic material. The nucleic acid may be single- or double-stranded. The entire infectious virus particle, called a virion, consists of the nucleic acid and an outer shell of protein. The simplest viruses contain only enough RNA or DNA to encode four proteins.
Are viruses considered living?
Viruses are not living things. Viruses are complicated assemblies of molecules, including proteins, nucleic acids, lipids, and carbohydrates, but on their own they can do nothing until they enter a living cell. Without cells, viruses would not be able to multiply. Therefore, viruses are not living things.
How much DNA is in a virus?
Eight percent of our DNA consists of remnants of ancient viruses, and another 40 percent is made up of repetitive strings of genetic letters that is also thought to have a viral origin.”
