for example:
If a hemoglobin (red blood cell) shape changed, (this is normally called sickle cell) the red blood cell would be to unable to travel through the body with ease and easily clog bloodstreams. Also, the hemoglobin will not be able to transport as much oxygen throughout the body.
Less than or equal to 45 mg/do or less than or equal to 2.5 mil/l. The following results are from a 21 years old patients with a back injury who appears otherwise healthy.
Infants show many reflexes as soon as they come out of their mother. Two of them are the sucking reflex and the root reflex. The root reflex is when the baby's side of the mouth is touch and they will then move their head towards where the were touched, allowing them to latch onto the breast or the bottle for food. The sucking reflex pretty much explains itself. When the roof of the baby's mouth is touched, they will begin to suck as they will think/know that it is feeding time.
Hope this helps!!
