ELIMINATION / EXCRETION / DEFECATION

A type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell. A type of nuclear division that produce 2 diploid daughter cells. Digestive enzymes essential for the digestion of carbohydrates and break down starches into sugar. Digestive enzymes that break down proteins into small peptides and amino acids. Digestive enzymes that break down the sugar, lactose found in dairy products. Mendel’s Law of Heredity that states that dominant trait is a trait whose appearance will always be seen in offspring. Organ of the digestive system that serves as entrance of food. The digestive system organ that has 3 parts which are namely the doudenum, jejunum and ileum. The digestive system organ that has 3 parts which are namely the ascending, transverse and descending colon. The digestive system’s food-churning organ. The first and upper part of small intestine that has a wider diameter. The long moist muscular tube that connects the oropharynx to the stomach. The part of the digestive system that comes next after the food is passed from the stomach. The part of the digestive system that holds the waste until elimination. The part of the digestive system where re-absorption and of water and salt occurs. The process of digestion when the undigested parts of food not absorbed by the body are eliminated as feces. The process when food is taken into the mouth. These are large biological molecules that speed up or catalyze chemical reactions in living organisms. This is defined as a group of similar organisms that are capable of reproducing their own kind. Type of digestive disorder which is prevented through oral rehydration.

Why do we need to initially chew our food before swallowing it? 64. Justify how enzymes affect digestion? 65. What is the reason of practicing proper nutrition and healthy lifestyle as the 2 bases in maintaining a healthy digestive system? *******

Commented [PJACC45]: Due to the Crossing-over in Meiosis cell division that results to variation or differences among siblings. Commented [PJACC46]: TO avoid choking / being choked To mechanically breaks down the food into smaller pieces that would prevent us from choking thus facilitate chemical digestion in the alimentary canal.
