Capillarity, also known as capillary action, is a physical phenomenon where liquid flows in narrow spaces without the assistance of, or even in opposition to, external forces like gravity. This movement occurs due to the cohesive and adhesive forces between the liquid and the surface of the tube. The process is responsible for various natural and biological processes including the movement of water within the stems of plants and the circulation of blood in tiny blood vessels in humans.

The green algae are the large group of algae from which the embryophytes emerged. As such, they form a paraphyletic group, although the group including both green algae and embryophytes is monophyletic. The green algae include unicellular and colonial flagellates, most with two flagella per cell, as well as various colonial, coccoid and filamentous forms, and macroscopic seaweeds. In the Charales, the closest relatives of higher plants, full differentiation of tissues occurs. There are about 8,000 species of green algae. Many species live most of their lives as single cells, while other species form colonies, coenobia, long filaments, or highly differentiated macroscopic seaweeds.
A few other organisms rely on green algae to conduct photosynthesis for them. The chloroplasts in euglenids and chlorarachniophytes were acquired from ingested green algae, and in the latter retain a vestigial nucleus. Green algae are also found symbiotically in the ciliate Paramecium, and in Hydra viridis and flatworms. Some species of green algae, particularly of genera Trebouxia and Pseudotrebouxia, can be found in symbiotic associations with fungi to form lichens. In general the fungal species that partner in lichens cannot live on their own, while the algal species is often found living in nature without the fungus. Trentepohlia is a green filamentous alga that can live freely on humid soil, rocks or tree bark or form the photosymbiont in lichens of the family Graphidaceae.

A pericardial vein is any vein that drains blood from the area around the heart, specifically the pericardium, and typically empties into the azygos or brachiocephalic veins. It helps in the circulation of blood around the heart tissues. The pericardium is the double-walled sac containing the heart and the roots of the great vessels.

Pinus cembroides, commonly known as Mexican pinyon, Mexican nut pine or Mexican stone pine, is a species of pine tree native to Mexico and the southwest of the United States. Its notable for producing large seeds, known as pine nuts, which are often used in cooking. It is a small to medium-sized tree that prefers semi-arid climates and grows well on rocky soils.

Nourishing refers to providing nutrients needed for growth, health, and optimal functioning. It often pertains to food, but can also imply providing mental, emotional, or spiritual sustenance that promotes overall well-being.
