In an adult human, blood forms 7% to 8% of the whole body weight and contains around 5 liters. However, this total volume varies considerably with an individualâs size, composition of body, and state of training. Red blood cells, white blood cells, and platelets are collectively called formed elements.The formed elements constitute 40% to 50% of total blood volume.ed blood cells, also known as erythrocytes, are the main formed component of blood, and they constitute 45% of the blood volume in an adult human.

Paraplegia is a medical condition where a person experiences loss of movement and/or loss of feeling in the body. This usually occurs after an injury to the nervous system. Paraplegia can involve complete or partial paralysis of the legs and/or the trunk. The severity and location of the damage to the nervous system determines the extent of the paralysis. In paraplegia, only the lower half of the body is paralyzed. Paralysis of the complete body, including arms, is known as Quadriplegia and Paraplegia. Depending on the extent and location of the damage to the nervous system, there are some patients who can resume minimal function. Majority of the patients suffering from paraplegia will have this condition permanently.
