Dental formula of human being |
|
Answer» The dental formula expresses the arrangement of teeth in each half of the upper jaw and the lower jaw. The entire formula is multiplied by two to express the total number of teeth. The dental formula for milk teeth in humans is: `(2102)/(2102)xx2=20` Each half of the upper jaw and the lower jaw has 2 incisors, 1 canine, and 2 molars. Premolars are absent in milk teeth. The dental formula for permanent teeth in humans is: `(2123)/(2123)xx2=32` Each half of the upper jaw and the lower jaw has 2 incisors, 1 canine, 2 premolars, and 3 molars. An adult human has 32 permanent teeth. |

Answer briefly: (a) Why are villi present in the intestine and not in the stomach? (b) How does pepsinogen change into its active form? (c) What are the basic layers of the wall of alimentary canal? (d) How does bile help in the digestion of fats? |
|
Answer» Correct Answer - (a) Villi are present in the intestine to increase the area of intestine so that absorption of digsted food occurs efficiently. (b) Pepsingen (inactive form) is first changed by HCI into an active enzyme pepsin. Then, through autocatalysis, more of pepsinogen gets activated to pepsin. Thereafter, pepsin hydrolyses the proteins partially to proteoses and peptones. Pepsinogen + `HCI to` pepsin Proteins `overset("Pepsin")(to)` proteoses and peptones (peptides) (c) The wall of alimentary canal consists of four main concentric coats. Beginning from outside, these coats are -- (iv) Visceral peritoneum (ii) Muscular coat (iii) sub-mucosa, and (iv) mucosa |

If the inner surface of the ileum in the human small intestine was smooth, rather than being folded and subdivided into villi, which of the following statements would be true?A. The rate of absorption of digested food molecules would be higher, because the digested food would pass more easily thorugh the digestive tract.B. Digestion would not be as effective, because there would be fewer cells scretting trypsin (a protein-digesting enzyme).C. Humans would have needed to evolve a much longer small intesntine to absorb sufficient nutrients from their food.D. Humans would not be able to survive, because the digestive tract would be more susceptible to damage. |
|
Answer» Correct Answer - C The absorptive surface of small intestinal mucosa have folds, which increase its surface area Also located on epithelial surface of small intestine are millions of small villi. Intestinal epithelial cell on each villus is characterised by a brush border which further increaes the surface area. Thus, to compensate for this and to have effective absorption of nutreints. intestine would need to be much-much longer in length |
