What is the function of the lymphatic system?
tranport fluid back to blood, proteins back to blood, protect from antigens, absorb lipids from the GI tract.
What is lymph?
a clear yellow fluid formed from the exchange of materials in capillaries.
What does lymph contain?
Water, protein, lipids, and electrolytes.
What do the lymphatic vessels do?
They carry lymph from the periphery back to blood.
What pathways are used to carry lymph to the blood?
Lymph capillary, lymph vessel, lymph trunk, and lymph ducts.
What are lymph capillaries?
Blunt end sacs that contain valves, are one cell thick, they allow lymph to enter only, and absorb lymph from interstitial fluid and GI tract.
What are lymph vessels?
they're formed by the joining of several lymph capillaries they contain valves(to stop backflow of lymph) they also contain lymph nodes(which contain white blood cels, and help fight antigens.) Lastly they move the lymph superiorly.
What is the lymph trunk?
they are formed by several lymph vessels and move the lymph superiorly.
What are lymph ducts?
they are formed by several lymph trunks.
What are the two types of lymph ducts?
The thoracic duct and the Right lymphatic duct.
What does the thoracic duct do?
It collects lymph from the body below the diaphragm and from the left half of the body above the diaphragm.
What does the right lymphatic duct do?
It collects lymph from the right part of the body above the diaphragm.
Where is lymph dumped?
it's dumped into the blood at a junction between the sublclavian and jugular veins.
How is lymph kept from flowing backward?
Valves.
How is lymph moved uphill?
By skeletal muscle contraction.
How is lymph pulled upward?
By pressure changes when you breathe.
What do lymphatic organs do?
They are involved in antigen protection.
What are some examples of lymphatic organs?
Tonsils, lymph nodes, spleen and the thymus.
What is the function of blood?
Transportation, regulation of ph, and protection of body and blood.
What does blood transport?
Oxygen, carbon dioxide, nutrients, waste, hormones, water, and proteins.
How does blood protect the body?
Involved in hemostasis(blood clotting), helps to fight infection, and fights antigens.
What type of tissue is the blood?
connective tissue.
What are Erythrocytes and what do they do?
they are red blood cells and they transport oxygen and carbon dioxide to and from the tissue. They also contain hemoglobin.
