The requirements for a contract in Anglo-American law are that there be an offer, an acceptance, consideration and an intention to effect legal obligations. Scots law, because of its civilian origins, does not require the consideration.
Neutrophils are the most abundant white blood cell, constituting 60-70% of the circulating leukocytes. They defend against bacterial or fungal infection. They are usually first responders to microbial infection; their activity and death in large numbers forms pus.
A high white blood cell count (leukocytosis) is most often due to an infection, but can occur during many different illnesses. Certain medications, such as oral corticosteroids, also increase the white blood cell count. A low white blood cell count (leukopenia) is less common.
