Summary Introduction

To determine:

The function of digestive system.

Introduction:

Digestive system is responsible for ingesting and digesting the food, absorbing the nutrients and eliminating the waste. The main organs of digestive system are mouth, tongue, salivary gland, pharynx, esophagus, stomach, small intestine, rectum, pancreas, liver, gallbladder and anus

Expert Solution & Answer

Explanation of Solution

Digestive system involves the process of food breakdown with the help of digestive organ, so the nutrients present in food can be absorbed by the cells in body. The functions of digestive system are as follows;

Ingestion:

it occurs when the foods and liquids enter in the digestive tract via mouth.

Mechanical processing:

it involves crushing of food with tongue, tearing and crushing with the teeth. Grinding, churning and crushing and propulsive moments provides by the alimentary canal aids the mechanical processing after ingestion.

Digestion:

it is chemical and enzymatic breakdown of food into carbohydrates, lipids and proteins. Small organic molecules are absorbed by the digestive epithelium of stomach and intestines.

Excretion:

it involves removal of indigested waste product after digestion

Conclusion

Digestive system helps in food break down into small molecule like carbohydrate, fat and protein that provide nutrition to each cell in the body and undigested waste material is excrete out from the body.

A sample of blood was taken from the above individual and prepared for haemoglobin analysis. However, when water was added the cells did not lyse and looked normal in size and shape. The technician suspected that they had may have made an error in the protocol – what is the most likely explanation?   The cell membranes are more resistant than normal.   An isotonic solution had been added instead of water.   A solution of 0.1 M NaCl had been added instead of water.   Not enough water had been added to the red blood cell pellet.   The man had sickle-cell anaemia.

With reference to their absorption spectra of the oxy haemoglobin intact line) and deoxyhemoglobin (broken line) shown in Figure 2 below, how would you best explain the reason why there are differences in the major peaks of the spectra? Figure 2. SPECTRA OF OXYGENATED AND DEOXYGENATED HAEMOGLOBIN OBTAINED WITH THE RECORDING SPECTROPHOTOMETER 1.4 Abs < 0.8 06 0.4 400 420 440 460 480 500 520 540 560 580 600 nm 1. The difference in the spectra is due to a pH change in the deoxy-haemoglobin due to uptake of CO2- 2. There is more oxygen-carrying plasma in the oxy-haemoglobin sample. 3. The change in Mr due to oxygen binding causes the oxy haemoglobin to have a higher absorbance peak. 4. Oxy-haemoglobin is contaminated by carbaminohemoglobin, and therefore has a higher absorbance peak 5. Oxy-haemoglobin absorbs more light of blue wavelengths and less of red wavelengths than deoxy-haemoglobin
