Biologists have found solid proof that among the insect tree of life, the relationship between the immune and circulatory systems is consistent. The discovery will help researchers understand how ...

Researchers are closer to understanding the earliest beginnings of the circulatory system during embryonic development—a discovery that could lead to ways to repair damage in the human body after ...

The metabolic activity of any tissue is limited by its blood supply; the more active any organ, the more blood it needs and the more extensive its vascularization. The changes in metabolic activity ...

A circulatory system (sometimes cardiovascular system) is an organ system that moves substances to and from cells; it can also help stabilize body temperature and pH (part of homeostasis). There are ...

Vanderbilt biologists have discovered the genetic pathways that link the immune and circulatory systems of mosquitoes during the fight against infection. A mosquito fighting infection of malaria or ...

A process of surgically joining the circulatory systems of a young and old mouse slows the aging process at the cellular level and lengthens the lifespan of the older animal by up to 10%. A process of ...

The metabolic activity of any tissue is limited by its blood supply; the more active any organ, the more blood it needs and the more extensive its vascularization. The changes in metabolic activity ...

There are about 30-40 billion white blood cells present in our body to fight against infective and foreign organisms. On average, human blood circulates through the whole body every 23 seconds.

The circulatory system is essential for the transfer of nutrients and oxygen to all cells of the body. The system consists of the heart and the blood vessels whose branches run throughout the body.

Action is needed locally, nationally, and internationally to curb sales of new sports utility vehicles (SUVs) to reduce their potential harms to health and the environment, say experts in The BMJ's ...
