Lymphatic System and Lymphedema Test
Lymph arises from plasma that leaves the blood arteries and gathers in the
interstitium.
**As blood flows from the high pressure arteries and moves into the veins, water
and solutes enter the lymph system.
What is in lymph? - Answer: proteins.
water
Fatty Acids
Cellular components
Microcirculation - ANSWER Starling's law determines the net flow into and out of
the capillaries.
(plasma colloidal osmotic, interstitial fluid hydrostatic, and interstitial colloidal
osmotic)
10-10% of plasma enters the lymphatic system!
purpose of the lymphatic system - ANSWER one-way system designed to convey
lymph distal to proximal through a series of superficial-->deep-->nodes-->venous
-Waste removal
Fluid homeostasis
- Immune defence
,-transport and drain surplus fluids.
The lymphatic system is also known as the ANSWER sanitation system.
What makes lymph abundant in protein? ANSWER: albumin.
Direction of lymph - 1) lymph capillaries
2) Pre-collectors
3) Collectors.
4) trunks.
5. Ducts
6) Heart (circulation)
lymphatic tissue - ANSWER macrophages
lymphocytes
plasma
antibodies
lymphatic organs - ANSWER bone marrow
Lymph nodes
spleen
tonsils
thymus
, Peyer patches
The thymus is an organ located above the heart in which T-cells grow and become
specialized.
The spleen processes blood and eliminates faulty RBCs.
Keep them reserved in case of hemorrhage.
ANSWER: Lymph capillaries create a plexus throughout the body.
- situated superficially (epidermis).
flap-like apertures linked to tissue
Flows in any direction.
collectors - ANSWER connect superficial capillaries with deeper veins
ANSWER: Transport to nodes and trunks.
-like veins, but with thinner walls
-valves
-smooth muscles
Lymphangion is a functional unit that gathers between the distal and proximal
valves and conveys through peristaltic contractions.
**also helped with muscular pumps.
