Superficial set: cephalic veins
|
(lateral, thumb side)
Start at bend of wrist and go up to open into the axillary vein. |
|
|
Superficial set: basillac vein
|
become axillary at armpit (medial).
Basilac starts at bend of wrist and becomes axillary, receives the cephalic. |
|
|
deep set:
|
two companion veins coiled around arteries,
pick up name of artery. are distal to axillary and politeal fossa. |
|
|
Brachiocephalic veins
|
formed by union of subclavian and internal jugular veins.
|
|
|
Superior Vena Cava
|
drains blood from upper extremeties into right atrium
|
|
|
Superior Vena cava in order
|
a. Right brachiocephalic vein
b. Left brachiocephalic vein c. Azygos system |
|
|
Azygos system
|
drains groups of veins that match arteries
same name as groups. empty into each other into superior vena cava then right atrium. |
|
|
Veins of the lower extremeties
a. superficial set |
in the skin
|
|
|
Veins of the lower extremeties:
Greater cephanous vein |
used in bypass.
longest vein in body located on medial side of lower extremity |
|
|
Lesser cephanous vein
|
on lateral side of lower extremity,
dumps into popliteal at bend in knee. |
|
|
Veins of the lower extremeties:
deep set |
same name as arteries.
deep veins are companions to and coil around arteries around lower extremities. |
|
|
Common iliac veins
|
formed by union of external and internal iliac veins.
|
|
|
Inferior Vena Cava
|
formed by union of external and internal iliac veins.
come together at L4. |
|
|
Inferior Vena Cava:
portal system |
in abdomen in front of paired veins (by intestines) clinical correalation- 25% of total blood volumes is in portal system. The system begins in capillaries and ends in capillaries. Capillaries are barriers for blood to leave the system. Blood thickens after death, viscosity increases. 25% total blood volume may never get out the drain tube. Need for thorough aspiration of abdominal cavity.

|
Inferior Vena Cava:
lumbar veins |
5 pairs,
tributaries into inf. vena cava |
|
|
Inferior Vena Cava:
gonadal veins |
reproductive organs, 2 pairs
|
|
|
Inferior Vena Cava:
renal veins |
2 pairs, kidneys
|
|
|
Inferior Vena Cava:
suprarenal veins |
adrenal glands, 2 pair
|
|
|
Inferior Vena Cava:
inferior phrenic veins |
bottom of diaphragm, 2 pairs
|
|
|
Inferior Vena Cava:
hepatic veins |
liver, 3 veins
come out of liver to Inferior vena cava. |
|
|
Inferior Vena Cava:
hepatic portal vein |
1.
enters liver. comes from intestine |
|
|
Lymph vascular system
|
between blood and cell system.
|
|
|
Structure of Lymph V.S.
|
3 tunics like veins, thin.
difference lymphatics have lymph nodes. Veins get bigger as get closer to heart, lymphs do not. |
|
|
Cisterna chili
|
sac contain mile like lymph, forms the lacteals.
drain the gut |
|
|
Thoracic duct: (left lymph duct)
|
18" long
goes behind heart, empties into left subclavian veins. drains 3/4 of anatomy. |
|
|
Right lymphatic duct
|
drains upper right quadrant.
short, 1/2" long. opens into right subclavian vein, joins blood stream as plasma. |
|
|
lymph nodes
|
lymph nodes have two major functions:
filter blood produce lymphocytes (lymph cells) lymphocytes are valuable in creating antibodies for immunity against disease. |
|
|
tonsils
|
pharyngeal (adnoids),
paletines (two) occasionally lymph nodes on tongue called lingual tonsils All 3 are aggregations of lymph nodes |
|
|
spleen
|
upper left quadrant of abdomen.
spleen is largest mass of lymphoid tissue in anatomy. |
|
|
Thymus
|
aggregation of lymph nodes
grows to age 12 then atrophies as we grow older. Process of thymus is for T-cells, (lymphocyte production) |
|
|
Function: lympatic
|
Two major functions: filter the blood and to produce lymphocytes
|
