The orca's body, like that of other living creatures, is made up of cells. Eukaryotic cells are seen in orca whales. Cells of this sort can be found in all mammals. A nucleus is found in eukaryotic cells. The nucleus is the cell's brain. The nucleus directs the activity of the cell in the same way as the human brain directs the movements of the body. DNA is found in the nucleus. The blueprint for an animal's body is DNA. The genetic code is carried by DNA. The messenger RNA transports the DNA information to the ribosome, which is where proteins are produced. Organelles, which serve as miniature organs with various functions, are found in every cell. Killer whales have 44 chromosomes, and an outstanding banding investigation on six killer whales revealed significant C-band variation. Because they have complex cells, killer whales are classified as Eukaryotes. Membrane-bound organelles, including a nucleus, are found in their cells.
Humans are complex organisms made up of trillions of cells, each with their own structure and function. Scientists have come a long way in estimating the number of cells in the average human body. Most recent estimates put the number of cells at around 30 trillion.
An Orcas largest cells can be the size of a Honda to the size of a school bus, depending on genetics. Orcas have 3 times as many cells as humans, and the cells are much larger. Orca cells are the largest cells in the Ocean, including Whale Sharks and Great White Sharks. Orca cells are much stronger than any other cell to any animal.
Protein digestion would be more difficult because of that buffering action of sodium bicarbonate on the stomach acid, which alters the optimum pH for the action of pepsin, a major protein-digester
