Flow of lymph through body
Need help with the sequence (s) of the flow
right foot
Right arm
Intestines ( with fat )
& where to put the little clusters of lymph nodes through which the lymph passes as it travels .
Tracing the Flow of Lymph through the Body In this procedure you will trace the pathway of lymph flow from the delivered to the cardiovascular system. You will trace the flow through th ducts, and highlight clusters of lymph nodes rom the starting point to the point at wessels, t g vessels, t through which the lymph passes as it travels. e major lymph-collecting 1 Write the sequence of the flow. 2 Then use differently colored water-soluble markers to draw the pathway on a laminated ourlin o cmnioint to the point at which the lymph is an bo If no outline is available, use colored pencils and Figure 12.6 Trace the flow from the following locations: and Figure 12.6 pathway on a laminated outline of the human bo Start: Right foot Start: Right arm .2 Start: Intestines (with fat) E12.6 Outline of hum FIGURE anterior view

Explanation / Answer

The lymphatic system is a closed system that is built up of the lymphatic capillaries, the lymphatic vessels as well as the lymph nodes. This system plays a major role in the toxin clearance as well as waste clean up from the various organs and the tissues. The lymph vessels have valves that prevent the back flow of the liquids. With this basic information about the lymphatic system, the flow of the lymph can be traced as follows:

1) Right foot :

--> The flow of lymph starts from the right foot and continues into the lymphatic capillaries

--> From the lymph capillaries, it moves into the collecting vessels of the right leg

--> The movement continues from the right collecting vessels to the inguinal lymph nodes at the right side itself followed by movement into the inguinal trunk

--> This is followed by movement into the chili cisterna and the thoracic duct

--> The final movement of the lymph occurs towards the junction between the left jugular veins and the left subclavian vein.

2) Right arm

--> The flow of lymph starts from the right arm, head and neck and continues into the lymphatic capillaries

--> From the lymph capillaries, it moves into the collecting vessels

--> The movement continues from the right collecting vessels to the inguinal lymph nodes at the right side itself followed by movement into the inguinal trunk

--> This is followed by movement into the chili cisterna and the thoracic duct

--> The final movement of the lymph occurs towards the junction between the right jugular veins and the right subclavian vein.

3) Intestine with fat

In order to absorb fat, there are special bodies present in the intestine known as lacteals. These lacteals absorb the fat globules. The lacteals will be present in the villi of the small intestine and absorb the dietary fats. The triglycerides are finally formed into chylomicrons, by the hydrolysis of lipase and bile emulsification, followed by re esterification to form triacylglycerols. This combines with cholesterol ester, B48 apolipoprotein and phospholipids to form chylomicrons. Chylomicrons move through the lacteals in the form of a milky substance called chyle. These lacteals merge and transport the milky chyle into the thoracic duct.

When there is no fat :

--> The flow of lymph starts from the intestine and the lower body and continues into the lymphatic capillaries

--> From the lymph capillaries, it moves into the collecting vessels.

--> The movement continues from the right collecting vessels to the inguinal lymph nodes at the right side itself followed by movement into the inguinal trunk

--> This is followed by movement into the chili cisterna and the thoracic duct

--> The final movement of the lymph occurs towards the junction between the left jugular veins and the left subclavian vein.
