Mechanical digestions starts from the intake of food into the mouth and when the food is chewed and while the food is broken down until it becomes small to be swallowed. Then the food goes down as a food bolus into the esophagus after the food is broken down. The food bolus passes through the alimentary canal through peristaltic movements. Peristaltic movements is a systematic series of muscle contractions and relaxation which involves the passage of food bolus through the esophagus‚ stomach‚ small

Unit 9 M1 Describe how the components of a balanced diet contribute to an individuals health at different stages. A balanced diet is food intake that includes all of the dietary needs of the organism in the correct proportions. In order to live a healthy lifestyle all individuals must have a balanced diet. A balanced diet is not about just eating fruit and vegetables‚ it is all based on eating the right adequate amount from the 5 food groups. Each food group has a purpose to the human body which

Introduction Sodium Hydroxide (NaOH) is a strong base and when it is titrated with a strong acid the equivalence point will be expected to be a pH of 7 (wyzant.com‚ Feb. 12). NaOH is also known as caustic soda‚ it is soluble in water‚ ethanol‚ and glycerol but is insoluble in acetone and ether (nap.edu‚ Feb. 12). When Phenolphthalein a weak acid and when hydroxide ions (NaOH) is added the indicator is turned pink (Chemguide.co.uk‚ Feb.12). The objective was to titrate a solution of Citric acid and

Reproductive System 1. How is a vasectomy performed? Be sure to cite the specific anatomical structures involved. How does this prevent pregnancy? Vasectomy refers to the surgical procedure that involves male fertilization that helps to perform lasting birth control. During this procedure‚ surgeon cut off part of the male anatomy called vas deferens that transports sperm from the epididymis to the ejaculatory ducts. It prevents further sperm entering into the seminal stream. After this procedure

melting point and the boiling point. Also you are able to measure the purity of a mixture using melting point tests. • In order to determine the melting point of a substance whose melting point was higher than 100 degrees Celsius you would use oil or glycerol just to achieve a higher temperature so you can run measurements at those high temperatures. Melting point can be measured very precisely at least for pure compounds. • Adding more crystals in the capillary tube would cause there to be errors in

ANATOMY AND PHYSIOLOGY OF THE DIGESTIVE SYSTEM The digestive system is basically a tube running through the body from the mouth to the anus. The organs of the digestive system include the oral cavity (mouth)‚ esophagus‚ stomach‚ small and large intestine and rectum. Their role is to break down food and deliver the products to the blood for dispersal to the body cells. The undigested food that remains in the tract leaves the body through the anus as feces. The break down activities that
