Functions Of Carbohydrates

The main function of Carbohydrates is to provide energy but they also play an important role in:

The construction of the body organs and Nerve cells

The definition of persons physiological identity such as their blood group

1. Energy source and storage

Starch and sugars are the main energy-providing carbohydrate sources and supply 4 kilocalories per gram.

Simple sugars are absorbed directly by the small intestine into the bloodstream, where they are, then, transport to their place of use. Disaccharides are broken down by the digestive enzyme into simple sugars. The body also needs the help of digestive enzymes to break down the long chains of starches into their constituent sugars, which are then absorbed into the bloodstream.

The human body uses carbohydrates in the form of glucose. Glucose can also be converted to glycogen, a polysaccharide similar to starch, which is stored in the liver and the muscles and is a readily available source of energy for the body. The brain needs to use glucose as an energy source since it can't use fat for this purpose. It is for this reason that the level of glucose in the blood must be constantly maintained above the minimum level. Glucose may come directly from dietary carbohydrates or from glycogen stores. Several hormones, including glucagon and insulin, work rapidly to regulate the flow of glucose to and from the blood respectively, to keep it at a steady level.

2.Protein sparing action

Maintaining a regular intake of carbohydrates will prevent the protein from being used as an energy source, thus sparing protein to perform its own function, which is bodybuilding. Furthermore, an adequate amount of carbohydrates will prevent the degradation of skeletal muscles and other tissues such as heart, liver, and Kidneys.

Digestive System

The digestive system is made up of the digestive tract- a series of hollow organs joined in a long, twisting tube from the mouth to the anus and other organs that help the body break down and absorb food. Organs that make up the digestive tract are the mouth, esophagus, stomach, small intestine, large intestine also called the colon-rectum and anus. Inside these hollow organs is a lining called the mucosa. In the mouth, stomach, and small intestine, the mucosa contains tiny glands that produce juices to help digest food. The digestive tract also contains a layer of smooth muscle that helps break down food and move it along the tract. Two "solid" digestive organs, the liver and the pancreas, produce digestive juices that reach the intestine through small tubes called ducts. The gallbladder stores the liver's digestive juices until they are needed in the intestine. Parts of the nervous and circulatory systems also play major roles in the digestive system.

PNF Stretching

PNF is an acronym for Proprioceptive Neuromuscular Facilitation . PNF is not really a type of stretching but is a technique of combining passive stretching and isometric stretching in order to achieve maximum flexibility. PNF was originally developed by a physical therapist as a method of rehabilitating stroke victims. PNF consists of a muscle being passively stretched, then contracted isometrically against resistance while in the stretched position and then being passively stretched again through the resulting increased range of motion. PNF usually employs the use of a partner to provide resistance against the isometric contraction and to then take the muscles through its increased range of motion.

What is Anatomy?

WHAT IS ANATOMY? Anatomy is the branch of biology, concerned with the study of the structure of living organisms and their parts. It is the structural study of the organism including their systems, organs, and tissues. In simples words, anatomy is the GPS of our body. This picture represents the STANDARD ANATOMICAL POSITION which one must remember in order to learn about anatomy. source: google WHAT IS STANDARD ANATOMICAL POSITION? Standard anatomical position is what will help us to have reference points. We need to know that standard anatomical position because the human body is dynamic and keeps changing position. Anatomical position is like a body-map, it is the reference position where: Body is standing upright feet shoulder width apart and parallel Toes forward Arms to the sides Palms facing forward face in the front Eyes are wide open This is the starting position for all muscle actions. The body is standing upright with the arms at t...
