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
|
