Blood vessels. These bring blood to the lungs, where oxygen enters the bloodstream, and then to the body: The inferior and superior vena cava bring oxygen-poor blood from the body into the right atrium.The pulmonary artery channels oxygen-poor blood from the right ventricle into the lungs, where oxygen enters the bloodstream.The pulmonary veins bring oxygen-rich blood to the left atrium. The aorta channels oxygen-rich blood to the body.hese bring blood to the lungs, where oxygen enters the bloodstream, and then to the body: The inferior and superior vena cava bring oxygen-poor blood from the body into the right atrium.

Empiricism is a philosophical belief that states your knowledge of the world is based on your experiences, particularly your sensory experiences. According to empiricists, our learning is based on our observations and perception; knowledge is not possible without experience.
An electromagnetic pulse (EMP) is an intense burst of electromagnetic (EM) energy caused by an abrupt, rapid acceleration of charged particles, usually electron s. An EMP can contain energy components over a large part of the EM spectrum, from very-low-frequency ( VLF) radio to ultraviolet ( UV) wavelength s. A lightning strike produces a localized EMP that gives rise to large electrical current s in nearby wires.
