Whether the following statements are true or false. False statements are to be corrected. a. The crown of a tooth is surrounded by an outer layer of pulp, which is the hardest substance in the body. b. The filiform papillae of the tongue are keratinized, which make them rough and able to assist in mechanical digestion. c. The three pairs of salivary glands are the parotid, submandibular, and sublingual glands. d. The exocrine cells of the pancreas and the salivary glands are islet cells. Introduction: The digestive system plays an important role in the human body. The digestive system starts with the oral cavity, where the food enters into the alimentary canal. The oral cavity resides many structures, which help in the mechanical tearing and breaking of any type of food. The salivary glands are the accessory organs that help in the movement of food in the alimentary canal.

Definition Definition Organ system that helps in the digestion of food by mechanical and biochemical processes. The digestive system breaks down food into simpler components that enable the body to then absorb or transport nutrients. The human digestive system includes the gastrointestinal tract or alimentary canal and the associate glands. The organs of the gastrointestinal tract include the mouth, pharynx, esophagus, stomach, small intestine, and large intestine. The associated glands include salivary glands, liver, gallbladder, and pancreas.

After you feel comfortable with your counting method and identifying cells in the various stages of mitosis, use the four images below of whitefish blastula to count the cells in each stage until you reach 100 total cells, recording your data below in Data Table 1. (You may not need to use all four images. Stop counting when you reach 100 total cells.) After totaling the cells in each stage, calculate the percent of cells in each stage. (Divide total of stage by overall total of 100 and then multiply by 100 to obtain percentage.) Data Table 1Stage Totals PercentInterphase Mitosis: Prophase Metaphase Anaphase Telophase Cytokinesis Totals 100 100% To find the length of time whitefish blastula cells spend in each stage, multiply the percent (recorded as a decimal, in other words take the percent number and divide by 100) by 24 hours. (Example: If percent is 20%, then Time in Hours = .2 * 24 = 4.8) Record your data in Data…
