Lymph vessel formation when new vessels emerge from the proliferation of pre-existing vessels.

The process whose specific outcome is the progression of a lymph vessel over time, from its formation to the mature structure.

Lymph vessel formation when new vessels emerge from the proliferation of pre-existing vessels.

The extension of new blood vessels from existing vessels into avascular tissues, this process includes the specialization of endothelial cells into leading tip and stalk cells, proliferation and migration of the endothelial cells and cell adhesion resulting in angiogenic sprout fusion or lumen formation.

The process in which the anatomical structures of venous blood vessels are generated and organized. Veins are blood vessels that transport blood from the body and its organs to the heart.

A process carried out by the organs or tissues of the respiratory system. The respiratory system is an organ system responsible for respiratory gaseous exchange.

The process of gaseous exchange between an organism and its environment. In plants, microorganisms, and many small animals, air or water makes direct contact with the organism's cells or tissue fluids, and the processes of diffusion supply the organism with dioxygen (O2) and remove carbon dioxide (CO2). In larger animals the efficiency of gaseous exchange is improved by specialized respiratory organs, such as lungs and gills, which are ventilated by breathing mechanisms.

Any process that increases or activates the frequency, rate, or extent of production of vascular endothelial growth factor.

Any process that increases or activates the frequency, rate, or extent of production of vascular endothelial growth factor.

Any process that increases the rate, frequency, or extent of the orderly movement of an endothelial cell into the extracellular matrix to form an endothelium.

Any process that increases the rate, frequency or extent of protein maturation by peptide bond cleavage.

Any process that increases the rate, frequency or extent of protein maturation by peptide bond cleavage.

The process whose specific outcome is the progression of the lung over time, from its formation to the mature structure. In all air-breathing vertebrates the lungs are developed from the ventral wall of the oesophagus as a pouch which divides into two sacs. In amphibians and many reptiles the lungs retain very nearly this primitive sac-like character, but in the higher forms the connection with the esophagus becomes elongated into the windpipe and the inner walls of the sacs become more and more divided, until, in the mammals, the air spaces become minutely divided into tubes ending in small air cells, in the walls of which the blood circulates in a fine network of capillaries. In mammals the lungs are more or less divided into lobes, and each lung occupies a separate cavity in the thorax.

A series of molecular signals initiated by the binding of a vascular endothelial growth factor (VEGF) to a receptor on the surface of the target cell, and ending with regulation of a downstream cellular process, e.g. transcription.

Any process that activates or increases angiogenesis.

The process in which the anatomical structures of blood vessels are generated and organized. The blood vessel is the vasculature carrying blood.

The process in which the anatomical structures of venous blood vessels are generated and organized. Veins are blood vessels that transport blood from the body and its organs to the heart.

The orderly movement of venous endothelial cells out of the veins giving rise to the precursors of lymphatic endothelial cells.

The orderly movement of venous endothelial cells out of the veins giving rise to the precursors of lymphatic endothelial cells.

Any process that activates or increases the frequency, rate or extent of vascular endothelial growth factor signaling pathway.

Any process that activates or increases the frequency, rate or extent of vascular endothelial growth factor signaling pathway.

Any process that activates or increases the frequency, rate or extent of lymphangiogenesis.

That part of a multicellular organism outside the cells proper, usually taken to be outside the plasma membranes, and occupied by fluid.
