What's the function of the digestive system?
to alter the chemical and physical composition of food so that it can be absorbed and utilized by the body cells
Lymph Ducts - Thoracic
Principle lymph duct of all areas except right side of head, neck and thorax and largest lymphatic vessel in the body
Lymph Ducts - Right Lymphatic Duct
Short duct, recieves lymph from the right side of the head, right upper extremity and right side of thorax
How is Lymph moved?
* Contraction of skeletal muscles and smooth muscles in the digestive tract
* Respiratory movement
Function of the Lymphatic System
return the fluid filtered out of the blood capillaries to the bloodstream
Metobolic Rate
the amount of head produced by the body in a given time and under certain circumstances
Metabolism
*Catabolism
*Anabolism
Catabolism: burning of absorbed foods to supply heat and chemical energy
Anabolism: use of food building body tissues, cell growth, repair and reproduction (depenedent on catabolism)
2 types of Digestion
Mechanical: actioin of teeth movements of the msucular walls or various portions of the alimentary canal
Chemical: Changes induced by enzymes produced by digestive glands
Where does the major part of absorption of nutrients occur?
Small Intestines
5 important functions of the liver
1) formation of blood constituents such as plasma proteins necessary for blood clotting
2) metabolism of carbs, fats, proteins, vitamins, and hormones
3) detoxification of harmful substances
4) Primary source of body head due to the chemical reactions occuring within cells
5) acts as a reservoir for blood
Intestinal Vili
In the small Intestines, finger like projetions that assist with digestion
Organs of the Alimentary Canal
Mouth-accessory digestive organs and taste sensation
Pharynx-passageways for food and air
Esophagus-connects from the thorat (pharynx) to the stomach
Stomach-there are specific glands in each section of the stomach that produce various gatric juices necessary for digestion of food
Small Intestine-The first twenty feet or so of the intestinal tract, where digestion of food and absorption of nutrients
Large Intestine-also called the colon; absorbs water from stool and changes it from a liquid to a solid form
Where does the digestive process begin?
The brain - salivary glands secretion is under the nervous control, occurring reflex when mechanical, chemical, or thermal stimuli act on sensory receptors int he mouth and other digestive organs
Lymphoma
A cancer of the lymph nodes
Thymus Gland
A lymphoid organ situated towards the front of the chest area, the thymus produces T-cells for the immune response
Spleen
An abdominal organ that produces cells involved in immune response
Tonsils
The infection-fighting lymph tissue located on either side of the back of the mouth
Lymph Nodules
small bundles of lymphatic tissue that remove cell waste and fight infections in the body
Adenitis
inflammation of a gland or lymph node
