BULBUS ARTERIOSUS Meaning and
Definition
-
The Bulbus Arteriosus, also known as the Outflow Tract, is a structure found in the heart of various vertebrates, including fish, amphibians, and reptiles. It is a muscular chamber located between the ventricle and the initial portion of the main artery that carries blood away from the heart, called the aorta. In mammals, including humans, this structure is known as the Conus Arteriosus and is less prominent.
The main function of the Bulbus Arteriosus is to regulate blood flow and maintain consistent pressure within the circulatory system. It acts as a buffer or reservoir, allowing blood to flow smoothly into the aorta and preventing sharp pressure changes during cardiac contractions.
The Bulbus Arteriosus contains elastic fibers that enhance its ability to stretch and recoil, allowing it to efficiently handle the pulsatile nature of blood flow. In some animals, it also includes specialized cardiac muscle fibers that aid in the regulation of blood pressure and cardiac output.
The precise structure and function of the Bulbus Arteriosus may vary among different species, reflecting adaptations necessary for their specific physiological needs. For example, in fish, it may assist in maintaining blood pressure during gill ventilation, while in reptiles and amphibians, it helps partition oxygenated and deoxygenated blood, preventing them from mixing within the heart chambers.
Overall, the Bulbus Arteriosus serves as an important component of the vertebrate cardiovascular system, contributing to the efficient circulation of blood and the maintenance of stable blood pressure.

Etymology of BULBUS ARTERIOSUS
The term "Bulbus Arteriosus" comes from Latin. "Bulbus" means "bulb" or "round swelling", and "arteriosus" means "arterial". The word is commonly used in biology and anatomy to describe a structure in the heart of certain animals, which forms part of the outflow tract of the ventricles.
