EXPERIMENT 13 DIGESTION IN THE SMALL INTESTINES ------------------------------------------------- ABSTRACT The small intestine serves as the site of major digestive and absorptive processes. In this experiment‚ the action of pancreatic enzymes on representative samples of each food group under different conditions‚ such as increased/decreased pH and presence of other substances‚ were observed. A pancreatin solution was first prepared from a hog pancreas and was completely neutralized using

Digestive system 6.1.1 explain why digestion of large food molecules is essential * Large food molecules are polymers‚ broken down into monomers in order to be absorbed into the blood * Humans eat substances by other organsims‚ many which are not suitable for human tissues therefore they must be broken down and reassembled in a form that is suitable * Many molecules in foods are too large to be absorbed by the villi in the small intestine‚ the large molecules have to be broken down

Excretory system Excretion is the removal of waste products of metabolism from our body system. Contents • 1 Excretory functions • 2 Component organs o 2.1 Lungs o 2.2 Kidneys o 2.3 Ureter o 2.4 Urinary bladder o 2.5 Urethra o 3 Urine formation4 Reasons For Excretion The excretory system removes metabolic and liquid toxic wastes as well as excess water from the organism‚ in the form of urine‚sweat‚urea or bile. This is important so as to help maintain balance within the organism

The endomembrane system is a system of organelles working together for the same goal. This system compartmentalizes the cell restricting certain metabolic reactions to certain areas of the cell. Phospholipids are a vital element of the endomembrane system it is these bilayers that cover structures like the nucleus‚ vacuoles‚ the endoplasmic reticulum (ER)‚ vesicles‚ and the cell itself. It is because of the unique properties of the phospholipid bilayer that vesicles are able to so easily fuse with

Human Digestion Activity The digestive process involves the mixing of food‚ the movement of food through the digestive tract‚ and a chemical breakdown of large molecules of food into smaller molecules. The digestive system is made up of the digestive tract and other organs that aid in digestion. The digestive tract is a series of hollow organs joined in a long‚ twisting tube from the mouth to the anus. Those twisted tubes include the mouth‚ esophagus‚ stomach‚ small and

Nervous System The nervous system is the part of an animal’s body that coordinates the voluntary and involuntary actions of the animal and transmits signals between different parts of its body. In most types of animals it consists of two main parts‚ the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS contains the brain and spinal cord. The PNS consists mainly of nerves‚ which are long fibers that connect the CNS to every other part of the body. The PNS includes motor

legislative‚ executive‚ and judicial branches of the government. Each branch has independent responsibilities and functions that are separate of the other branches. The legislative branch‚ which is headed by Congress‚ writes the law. The executive branch‚ headed by the President‚ carries out and enforces the law. And the judicial branch‚ headed by the Supreme Court interprets the law. 2. The system of checks and balances allows each branch of government to influence the activities of the other

of the fast food industry is due because of the social and technological advances that came during the early 19th century. Advances such as cars were a big contribution to the fast food industry. People could then drive to go and buy food. With cars‚ other advances in the industrial industry came along. Highways were built to travel from place to place. Much more advances have also contributed so that fast food was possible for everyone. Although there were many advances in the fast food industry that
