|
What percentage of lymph vessels are underneath the skin? |
70% |
|
|
What are the two major places we can find lymph nodes? |
1. Joints 2. Abdomen |
|
|
Name the two common divisions of the lymphatic system |
1. Superficial body 2. Deep Lymph pathways of Abdomen head, and neck |
|
|
Where do the lymph vessels in the legs drain to? |
The inguinal nodes |
|
|
The achilles tendon, posterior calf, and ball of foot all drain to what lymph node? |
Popliteal nodes |
|
|
What does "superficial belly" mean? |
From the waist down |
|
|
What does the circulatory system do? |
It distributes blood and fluid throughout the body |
|
|
What are Arteries? |
The largest blood vessels that transport oxygenated blood to the tissues of the body. |
|
|
What are Arterioles |
Smaller blood vessels that transport oxygenated blood from the arteries to the capillaries |
|
|
What are capillaries? |
The last stop for oxygenated blood moving through the blood vessels. The exchange of all fluid nutrients and wastes between the blood and tissues occurs here |
|
|
What are venules? |
Blood vessels larger than capillaries but smaller than veins that transport deoxygenated blood back to the heart |
|
|
What are veins? |
The largest blood vessels that transport deoxygenated blood back to the heart. |
|
|
What is interstitial fluid? |
Plasma that has entered the surrounding tissues |
|
|
What is plasma? |
A yellowish liquid component of blood that holds the blood cells, proteins and other parts of whole blood within it. |
|
|
What is the approximate percentage of interstitial fluid that is left behind and is transported through the lymph system? |
Between two and ten percent |
|
|
What key function do lymph vessels play? |
They remove proteins that are too big to get through the capillary walls |
|
|
Why do we need to remove excess protein from body tissue? |
Proteins draw water to themselves potentially causing edema |
|
|
What kinds of substances do lymph vessels transport? |
Proteins dead cells waste products bacteria viruses inorganic substances water Fats |
|
|
What is the initial lymphatic? |
The vessels of the lymphatic system that serve as the starting point for the removal of waste from body tissue. Analogous to capillaries. |
|
|
What does lymphatic drainage massage do to lymph flow? |
It increases the volume of lymph flow by as much as 20 times the regular amount. |
|
|
Why do we use a light pressure for lymphatic massage? |
1. It collapses the initial lymphatic, diminishing lymph flow 2. Potentially breaks the filaments that hold the lymphatic in place |
|
|
How long does it take for broken filaments of the lymph system to reform? |
24hours |
|
|
What is a precollector? |
Vessels that move lymph from the initial lymphatic to collectors. Larger than the IL but smaller than collectors |
|
|
What are collectors? |
The largest lymph vessels that have one way bicuspid valves. These valves prevent lymph from flowing in the wrong direction. |
|
|
What is a cusp? |
A pointed end where to curves meet |
|
|
What is a lymphagion? |
The functional unit of a lymph vessel that lies between two semilunar valves |
|
|
What kind of muscle are lymphagions made of? |
Smooth muscle |
|
|
What does "Angion" mean? |
Heart |
|
|
What are lymph trunks?1 |
A collection of lymph vessels that exit from the lymph nodes in specific areas of the body and service specific organ or limbs. |
|
|
Whats the range of lymph nodes in the body? |
Between 400 and 700 |
|
|
Whats the range of lymph nodes in the neck? |
Between 170 to 200 |
|
|
About how many lymph modes are located in the abdomen? |
Half of all lymph nodes in the body |
|
|
What do lymph nodes do? |
They filter and purify lymph using lymphocytes that destroy harmful substances in the body. |
|
|
What are afferent vessels? |
Lymph vessels that carry lymph towards lymph nodes |
|
|
What are efferent vessels? |
Lymph vessels that carry lymph away from lymph nodes |
