Nutrition and Digestion

What is Monogastric Digestion?
The human body contains a monogastric digestive system. In a monogastric digestive system, the stomach only contains one chamber in which it digests…
Anatomy of the Intestines
Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients,…
Accessory Organs
Accessory organs are those that participate in the digestion of food but do not come into direct contact with it like the mouth, stomach, or…
Lipid Digestion
Lipids are large molecules that are generally not water-soluble. Since most of the digestive enzymes in the human body are water-based, there are…
Protein Digestion
Protein digestion begins in the stomach, where the highly acidic environment can easily disrupt protein structure by exposing the peptide bonds of…
Carbohydrate Digestion
Carbohydrate digestion and metabolism break down simple and complex carbohydrates from food into saccharides (i.e., sugars) for the body to use as…
Neural Regulation
Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information…
Hormonal Regulation
Hormones regulate a significant portion of digestion through activation of the neuroendocrine system. The neuroendocrine system of digestion contains…
Measuring Oral Fatty Acid Thresholds, Fat Perception, Fatty Food Liking, and Papillae Density in Humans
Emerging evidence from a number of laboratories indicates that humans have the ability to identify fatty acids in the oral cavity, presumably via…
Scanning Skeletal Remains for Bone Mineral Density in Forensic Contexts
The purpose of this paper is to introduce a promising, novel method to aid in the assessment of bone quality in forensically relevant skeletal…
Treatment of Ligament Constructs with Exercise-conditioned Serum: A Translational Tissue Engineering Model
In vitro experiments are essential to understand biological mechanisms; however, the gap between monolayer tissue culture and human physiology is…
