Do camels have nucleated Red cells? 

Quote from the above source: "The hypothesis is that  they  throw  back  to  the  ancestral  reptiles  and other lower vertebrates seemed superficially obvious, and  perhaps  led  to  the  error  often  published  that camel erythrocytes are nucleated.  In fact, they are anucleate"

Like all mammals, camel red blood cells are without a nucleus. This is a very useful adaptation to increase oxygen carrying potential.

However, their red blood cells are a different shape (i.e. oval instead of doughnut shaped - see below). The importance of this is that they can be aligned in the direction of the blood flow, so the camel is at a much lower risk of complications from thickening blood when dehydrated.



Additionally, camel red blood cells are able to expand to 240 % of their initial size (only 150 % in other animals). As a result, they are able to hydrate their blood much more when given opportunity to drink water.

Vitamin B-6 breaks down a material known as homocysteine, which increases the risk of medical conditions such as heart attacks and strokes. Guavas/Bananas: Guavas are beneficial in regulating blood pressure. It is said that one guava contains almost a similar amount of potassium that's present in bananas.

THE IGNORANCE OF FASTING TODAY. In literary terms fasting can be defined as the abstinence of food for the attainment of spiritual edification. Lately, I got an insight that restructured my mindset towards this subject. During fasting, the pathway to your soul is open and ready for rejuvenation; Hence some folks contact strange spirits, sickness and mental disorder right there at the mountain of intercession. Praying and fasting is never the  sole patent of Born again Christians as everyone thought ; Even Occultic/mystic practitioners, Hindus, Buddhist and African traditional worshipers such as native doctors, rain makers, etc undergo fasting before embarking on heavy  incantations. Those in the business of Astral or soul traveling can decode what I'm saying. The two doors that opens to the soul during fasting includes: 1.Realm of divinity 2.Realm of premortal  darkness. When fasting is done in consonance with the principles of God, one plunges into the re...
