Typhoid fever is most common in non-industrialized countries. Travelers to Asia, Africa, Eastern Europe, and Latin America are especially at risk. Salmonella typhi bacteria are shed in the urine or stool of infected persons, including chronic carriers. There are no known animal reservoirs for typhoid fever.

The pluripotent, undifferentiated cells in the bone marrow that give rise to the formed elements are called _____ cells
LuckyWell [14K]

The pluripotent, undifferentiated cells in the bone marrow that give rise to the formed elements are called stem cells.

Pluripotent stem cells have the ability to undergo self-renewal and to give rise to all cells of the tissues of the body. However, this definition has been recently complicated by the existence of distinct cellular states that display these features.

There are two types of pluripotent stem cells :

  • Embryonic stem cells (ESCs)
  • Induced pluripotent stem cells

Embryonic stem cells are derived from the inner cell mass (ICM) of pre-implantation embryos and can be indefinitely maintained and expanded in the pluripotent state in vitro. Pluripotent stem cells can also be obtained by inducing dedifferentiation of adult somatic cells through a recently developed in vitro technology, known as cell reprogramming.

Similarly to  Embryonic stem cells , Induced pluripotent stem cells can be expanded indefinitely and they are capable to differentiate in all the derivatives of the three germ layers.

Another intriguing features of being pluripotent is its reliance on gene expression heterogeneity.

Explain how the body can shift the flow of blood from one organ system to another
Len [333]

Answer: The redirection of blood flow from one organ system to another is an outcome of coordinated vasomotion – constriction of precapillary sphincters and capillary blood vessels in tissues where blood flow is discouraged, and dilation in tissues where blood flow is promoted.
