The right lymphatic duct drains certain body area. Name some
|
(R) upper quadrant
(R) Arm |
|
Why is the intestinal lymph milky-white at times?
|
Fatty acids
|
|
What is the name of intestinal lymph?
|
Chyle
|
|
Where does the thoracic duct enter into the venous system?
|
Subclavian vein
|
|
What is the region of the inquinal lymph nodes?
|
(R) lower quadrant
(R) leg |
|
What is the name of the two veins that build the "venous angle"
|
Subclavian
Jugular |
|
What is the location of the thoracic duct? Cicterna Chyli
|
L2 up spine to (L) subclavian venous angle
|
|
What does lymph fluid consist of?
|
1. Proteins
2. Water 3. Cells (RBC,WBC) 4. Waste 5. Fat (intestinal lymph,Chyle) |
|
How many lymph nodes are in the human body?
|
600-700
|
|
What are the functions of lymph nodes?
|
1. filteration
2. absorb water 3. breaks down bacteria 4. production of WBC 5. regulates protein |
|
Occipital nodes are where?
|
Occipital region and upper part of the skin of the neck.
|
|
Retroauricular nodes are where?
|
Parietal area (EAR)
|
|
Preauricular nodes are where?
|
FOREHEAD, upper eyelid, lateral part of lower eyelid
|
|
Submandibular nodes are where?
|
Nose , upper and lower lip
Medial part of lower lid, CHEEK |
|
Submental nodes are where?
|
CHIN, medial part of lower lip
|
|
Describe the Structure of a blood capillary?
|
2 layers
Function: Diffusion,ultrafilteration and reabsorbtion takes place |
|
Describe the structure of Lymph Capillaries?
|
**similar to leach (septic) field, when one fills it goes on to the next.
REABSORBTION OF PROTEINS AND FLUID FROM THE INTERSTITIUM. ANCHORING FILIMENTS |
|
Define interstitium and interstitial fluid?
|
Interstitium: **like jello**
holds things together about 1/6 of the bod consists of this. Interstitial: **like pineapple in jello free fluid that the interstitium picks up. |
|
The most important process to nourish the tissue cells is called?
|
Diffusion
|
|
What causes ultrafilteration in the blood capillary?
|
BCP-Blood Capillary PRESSURE forces fluid OUT of the capillaries.
|
|
What causes reabsorbtion in the blood capillary?
|
COP- Plasma colloid osmotic pressure
Protein in the capillary |
|
Define Starling's Law.
|
The amount of fluid filtering outward from the arterial ends of capillaries EQUALS almost exactly the fluid returned to the circulation by absorption.
|
|
Where in the body dies filteration and reabsorbsion occur?
|
Venous side of the body.
|
|
What is "active hyperemia"?
|
DIALATION- blood flow increases-ultrafilteration increases-lymphatic flow increases!!
(Heat, Inflammation, Exercise) |
|
What is "passive hyperemia"?
|
OBSTRUCTION- blood backs up, blood pressure increase-lymphatic flow increases!
(Blood Clot, Cardiac edema) |
|
What is Hypoproteinemia?
|
DECREASED PLASMA- reduced reabsorbsion-increased lymphatic flow
|
|
Define "Lymphatic Load"
|
The amount of substances that have to be removed from the interstitium by the lymphatic system.
|
|
What does lymphatic load consist of:
|
1. Protein
2. Water 3. Cells 4. Fat |
|
Where in the body does the lymphatic system absorb fat?
|
Intestinal tract
|
|
LTV-Lymph time volume
High output failure Low output failure |
approx. 1-2 liters per day
Exceeds capacity-Edema drops below normal capacity-Lymphedema |
