Formation of tissue fluid and lymph Flashcards
What does the lymph system consist of?
- Lymph
- Lymph Vessels
- Lymph Nodes
- Lymph Organs (spleen and thymus)
- Bone Marrow
What are two lymph organs?
The spleen and the thymus
Identify three roles of the lymphatic system?
- it’s a drainage and filtrations system
- it removes excess fluid from body tissues
- it absorbs fatty acids and transports fat into the bloodstream to be absorbed into the small intestine
- It produces white blood cells which in turn can produce antibodies
What is hydrostatic pressure?
the pressure from heart contractions that forces water and dissolved substances through capillary walls into surrounding tissues
What forms as a result of hydrostatic pressure forcing water and dissolved substances in blood plasma out through capillary walls into surrounding tissues?
Tissue fluid
What is tissue fluid?
fluid between body cells
What is the role of tissue fluid?
Carries nutrients and oxygen to tissue cells
What is lymph?
fluid drained by the lymphatic system
What is lymph involved in?
removal of waste and infectious organisms from tissues
What are the most abundant plasma proteins?
albumins
Which proteins are the main contributors to the thickness of plasma and to osmotic pressure?
Albumins
What is Osmotic Regulation and what component of blood is involved with it?
The control of water content of the body, avoiding too much water entering or leaving cells
Plasma
What is Oedema?
A build up of fluid in the body causing fluid to leak from the bloodstream
What does Oedema cause?
causes the affected tissue to become swollen
Globulins are also a plasma protein. What is their role?
They are essential for the body’s immune response, they are a protective protein
What are globulins made by?
Lymphocytes (white blood cells)
What is a type of plasma protein other than albumins and globulins?
Fibrinogen
What is the role of Fibrinogen?
It assists in blood clotting to heal wounds
What plasma protein helps with blood clotting?
Fibrinogen
Which plasma protein is a protective protein and is essential for the body’s immune response?
Globulins
If plasma protein levels fall what happens?
The osmotic pressure also falls causing fluid to leak from the bloodstream
What is the difference between lymph and tissue fluid?
Tissue fluid is fluid between body cells whereas lymph is filtered watery fluid drained by the lymphatic system.
Tissue fluid carries nutrients and oxygen to tissue cells and lymph is involved in the removal of waste and infectious organisms from tissues
