Lymphatic Flashcards
our body’s ‘sewerage system’.
Lymphatic system
Considered as part of both circulatory and immune systems.
Lymphatic system
Plays a role in maintaining homeostasis whether by regulating fluid balance and protecting the body against diseases.
Lymphatic system
Functions of lymphatic system
Maintenance fluid
Lipid absoption
Defense
About ____ of fluid pass from the blood capillaries into the interstitial spaces each day whereas only ____
pass from the interstitial spaces
back to the capillaries
30 liters
27 L
The extra ____ of interstitial fluid
remained in the interstitial spaces.
3 L
The 3L of fluid enters the lymphatic capillaries. Once inside the lymphatic capillaries. This fluid is called as
Lymph
The lymphatic vessels that in the lining of small intestines
is called ___ that absorbs lipids and other substances
lacteals
The lymph passing through this lymphatic vessel
appears white because of its lipid content an is
called
Chyle
are filtered from lymph by the lymph nodes and from blood by the spleen.
Pathogens
capable of destroying pathogens
Lymphocytes
the fluid that flows through the lymphatic
system
Lymph
The average adult produces between ____ each day.
3-4 liters of lymphatic fluid
Carries fluid in one direction from tissues to circulatory system.
Lymphatic capillaries
Tiny closed ended vessel consisting of simple squamous
epithelium.
Lymphatic capillaries
It is more permeable to blood capillaries because it lacks
basement membrane
Lymphatic capillaries
Lymphatic capillaries joins to forms larger
lymphatic
vessels
have a beaded appearance because of one-way valves that are similar to the valves of the veins.
Small lymphatic vessel
Lymphatic vessel empty into the blood at two locations in the body:
- Lymphatic vessels from the upper right limb and right
half of the head, neck and chest form the right lymphatic duct which empties into the right subclavian vein. - Lymphatic vessel from the rest of the body enter the thoracic duct, which empties into the left subclavian vein.
Lymphatic organs
Tonsils
Spleen
Lymph nodes
Thymus
form a protective ring of lymphatic the nasal and oral cavities and the pharynx.
Tonsil
There are three paired of tonsils:
Pharyngeal tonsil
Palatine tonsil
Lingual tonsil
located near the internal opening of the nasal cavity.
Pharyngeal tonsil
located on each side of the posterior opening of the oral cavity
Palatine tonsil
