One prominent African crop exported during the triangular trade was tobacco. Grown in various regions, particularly in West Africa, tobacco was highly sought after in Europe and the Americas. The triangular trade facilitated the exchange of tobacco for manufactured goods and enslaved people, significantly impacting the economies of the involved regions.
The triangular passage, also known as the triangular trade route, refers to a historical trade network that connected Europe, Africa, and the Americas during the 16th to 19th centuries.

History
Triangular composition was most popular during the Renaissance.
During gestation the ductus venosus shunts most of the blood from the umbilical vein directly into the inferior vena cava. Shortly after birth the ductus venosus closes to allow normal circulation. It usually closes completely within the first week after birth, but can take longer in pre-term infants. After it is closes a small remnant remains and is called the ligamentum venosum.
