BLOOD
Blood is classified as a connective tissue, consisting of cells and cell fragments surrounded by a liquid matrix. The total blood volume in the average adult is approximately 4 to 5 L in females and 5 to 6 L in males. Blood makes up approximately 8% of the body's total weight.
The cells and cell fragments are the formed elements, and the fluid matrix is the plasma. The formed elements of the blood include several types of highly specialized cells and cell fragments. They are grouped into three major categories. Approximately 95% of the volume of the formed elements consists of erythrocytes (red blood cells or corpuscles). The remaining 5% consists of leukocytes (white blood cells or corpuscles) and platelets (cell fragments), which are also called thrombocytes.
Plasma is a pale yellow fluid accounting for slightly more than half the total blood volume and consisting of approximately 92% water and 8% dissolved or suspended molecules. Plasma contains proteins such as albumin, globulin, and fibrinogen. When the proteins that produce clots are removed from the plasma, the remaining fluid is called serum. In addition to the suspended molecules, plasma also contains a number of dissolved components such as salts, nutrients, gases, waste products, hormones, and enzymes. Water enters the plasma from the digestive tract, from interstitial fluids, and as a by-product of metabolism. Excess water is remived from the plasma through the kidneys, lungs, intestinal tract, and skin. Solutes in the plasma come from several sources such as the liver, kidneys, intestines, endocrine glands, and immune tissues such as the spleen.
The functions of the blood can be placed into the categories of transportation, maintenance, and protection. Blood transports gases, nutrients, waste products, and hormones. It is involved in the regulation of homeostasis and the maintenance of pH, body temperature, fluid balance, and electrolyte level. Blood protects against diseases and blood loss.
