Within the lymphatic system you will find a lymphatic vessels which are in a form of a network. These lymphatic vessels return the fluid that comes from tissues and proceeds by returning it to the bloodstream. Within the lymphatic vessels you will also find lymph fluid which travels towards the heart.
Trunks, ducts, and capillaries are the variations of the type of lymphatic vessels.
This type of lymphatic vessel is the smallest in terms of size and have thin walls. The main function of these capillaries are to obtain fluid from tissue that came from blood capillaries which however not returned. The walls are formed through one layer of endothelial cells which overlay each other which allows the fluid to pass through them. The consisting cells …show more content…
The capillary network forms thick walled vessels which then join in order to create lymphatic trunks then what we call lymphatic ducts. The lymphatic ducts contain several layers (three in total). In comparison to vein walls the layers are thinner than the vein walls. Their function is to deliver the lymph fluid into the subclavian veins which applies to the thoracic area
In order to provide the movement of the fluids skeletal muscles contract although the pressure of movement is low. The prevention of backflow is provided by valves that are found within the lymph vessels. Another factor that assists movement of fluid along the thoracic ducts comes from the process of inhaling. When we breath, it decreases pressure within the thoracic cavity which results in movement of the fluids.
The movement is also provided by the contraction of smooth muscles to assist fluids to travel through lymph trunks and ducts. Since the movement is slow in terms of the speed it travels it also means the rate of the returned lymph fluid will be equal to the rate of the fluid lost (from the bloodstream), however the speed can rise when the physical activity of your body rises which as a result causes production of tissue at faster rates from the
