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. Unlike the other formed-elements, the red blood cells contain hemoglobin, a pigment that binds and transport oxygen.
Paralysis is the loss of muscle function in part of your body. It happens when something goes wrong with the way messages pass between your brain and muscles. Paralysis can be complete or partial. It can occur on one or both sides of your body. It can also occur in just one area, or it can be widespread.
What Is Paralysis? Muscle is a special kind of tissue that enables our bodies to move. It is under the control of the nervous system, which processes messages to and from all parts of the body. Sometimes the nerve cells, or neurons, that control the muscles become diseased or injured. When that happens, a person loses the ability to move the muscles voluntarily, and we say that the person is paralyzed. Paralysis of the muscles of the face, arm, and leg on one side of the body is called hemiplegia (hemi means half) and usually results from damage to the opposite side of the brain. Damage to the nerves of the spinal cord affects different parts of the body, depending on the amount of damage and where it occurred.
