Module 4 Report

Unit 4 Report
Distributing Metabolites through the body
Food that we consume is composed of very complex molecules. During the digestive process these compounds are broken down into smaller and smaller subunits in preparation for use by the body as building blocks needed for the many components of the human body. In Module 3 we followed the food through the digestive system and considered the process that takes place in the digestive system.
The pizza that was eaten by Matt and Maria contained ingredients composed of fats, proteins, carbohydrates, and other components such as minerals, water and vitamins.
In this Report your focus is to research:
1) Based on your finding in the Module 3 Report, begin the Module 4 Report by identifying which metabolites are being absorbed and specifically which vessels of the cardiovascular or lymphatic system are the initial vessel of transport from the digestive system.
The nutrients obtained from food are absorbed in the intestines and
Calcium is the most abundant mineral in the human body, but needs other nutrients in order for it to be absorbed better and use properly. To metabolize calcium the hormones that help in that process are the parathyroid hormone and the modified steroid calcitriol a form of vitamin D, which promote better absorption of the calcium ion into the body’s circulation system and the counter balance protein hormone calcitonin promotes a decrease in circulating calcium. Calcium homeostasis is achieved by three central tissues, the kidney, intestines and bones. The hormonal target for calcium balance in bones is the osteoclast which can mobilize calcium to the body and phalanges by secreting proteolytic enzymes and acid onto the bone matrix in response to stimulation of the parathyroid hormone and
