02/21 Flashcards
What happens as blood pushes against the capillary walls?
Fluid is forced out of the capillaries
The fluid pushed out of capillaries contains
Water, ions, AA, glucose, and small proteins
What happens as water is being pushed out of the capillaries?
The solute concentration of capillaries at downstream end goes up
What brings water back into the capillary?
The increased solute concentration in the capillary
How are the cells in lymph capillaries?
Overlapping
What happens as pressure increases in interstitial space?
Fluid is forced into the capillary
Lymph capillaries have a
Blunt end
Fluid accumulates into
Lymph vessels
How much of water is in interstitial fluid?
3L
Cells that make up lymph capillaries are
Overlapping
What happens as tension increases in interstitial space?
Fluid is forced into capillary
Lymph is made of
Components of blood plasma
What dumps lymph back into the veins?
Lymph ducts
Lymph vessels have smooth muscle cells which
Contract and push fluid forward
What feed into the Vena Cava?
Subclavian veins
Where does lymph dump back?
In the subclavian veins
What facilitates lymph movement?
- Location of return
- Valves along lymph vessels
- Muscle contraction
What are the types of muscle contraction that assist in lymph movement?
- Smooth muscle found in the walls of the lymph vessels
- Skeletal muscle contraction putting pressure on vessels
Lymphedema is when there is
Blockage of lymph vessel
Lymphedema may be due to
- Vessel damage
- Tumor
- Parasite
Primary function of lymph vessels is
Returning fluid back to the heart
What is the function of Primary Structures?
They allow for the formation and maturation of lymphocytes like T cells and B cells
What examples of the Primary structures?
Thymus and Red Bone marrow
The Red Bone Marrow is the site of
Hematopoiesis and B-cell maturation
