General information
When we speak of vascular supply (vascular supply of coronary arteries), we must first distinguish between arteries, veins and lymph vessels. While arteries carry the oxygen-rich blood to the respective target organ, the oxygen-poor blood is transported back to the heart via veins after the organ has been perfused. Lymph vessels begin blindly at each organ and carry intracellular fluid through larger lymph vessels to the superior vena cava. Many vascular supply systems can be derived from knowledge of human embryonic development, since, to put it simply, there are different zones that are later supplied by the same vessels. Thus, if the embryonic development is known, many vascular supplies can be derived.
Systematics of the lymph vessels
In all parts of the body the smallest lymph capillaries begin blind. This means that there intracellular fluid flows into the smallest capillaries. Part of the lymphatic system are also the lymphatic organs (e.g. spleen and tonsils), where the differentiation of T-lymphocytes takes place.
These lymph capillaries then converge to local lymph nodes, where lymph fluid collects and then continues in larger lymph vessels until it reaches the thoracic duct, the largest lymph vessel in the body. Manual therapy (targeted massage) can increase the outflow of lymph and thus eliminate lymphedema (accumulation of water). Lymphedema can also be treated with compresses or medication.
Another interesting aspect of the lymphatic system are the lymph nodes associated with cancer (metastasis). An example of this is the lymph drainage of the breast, which runs through the lymph nodes of the armpits. Since in breast cancer cancer cells enter these lymph nodes via the lymph, metastases often form here, so that the lymph nodes must also be removed (vascular supply heart).
The heart is the central organ of the blood supply (vascular supply heart). It pumps oxygen-poor blood into the lungs to enrich oxygen and then into the body’s circulation. The largest artery in the body is the main artery (aorta).
All the vessels that ensure the arterial supply of the various tissues in the body come out of it. Depending on the location of the tissues, the venous return of the blood takes place via the upper or lower vena cava (superior/inferior vena cava). There is also a kind of detour system that runs parallel to the vena cava in the thoracic and abdominal cavity.
On one side this is the vena azygos, on the other side the vena hemiazygos. Both are connected to each other at the level of the heart and finally lead into the superior vena cava. Another special feature of the blood supply is the portal vein system of the liver.
The venous blood of all unpaired abdominal organs (everything except the genitals and kidneys) flows via the portal vein (vena portae) into the liver. There the nutrients contained in the blood are metabolized in the liver. The blood then passes through the liver veins (Venae hepaticae) into the inferior vena cava (Vena cava inferior) (vascular supply heart).
