Chapter review Blood is a fluid connective tissue critical to the transportation of nutrients, gases, and wastes throughout the body; to defend the body against infection and other threats; and to the homeostatic regulation of pH, temperature, and other internal conditions.
All of these nonprotein solutes combined contribute approximately 1 percent to the total volume of plasma. The remainder is mostly plasma proteins—mainly albumin, globulins, and fibrinogen—and other dissolved solutes such as glucose, lipids, electrolytes, and dissolved gases.
There are values given for percent saturation, tension, and blood gas, and there are listings for different types of hemoglobin. Because of the formed elements and the plasma proteins and other solutes, blood is sticky and more viscous than water.
Clinical training is required, but a degree may not be essential to obtaining a position.
Interactive link questions Visit this site for a list of normal levels established for many of the substances found in a sample of blood. More than 90 percent of plasma is water. Medical or clinical laboratories employ a variety of individuals in technical positions: Serum, one of the specimen types included, refers to a sample of plasma after clotting factors have been removed.
It is also slightly alkaline, and its temperature is slightly higher than normal body temperature.
While many allied health professionals practice phlebotomy, the American Society of Phlebotomy Technicians issues certificates to individuals passing a national examination, and some large labs and hospitals hire individuals expressly for their skill in phlebotomy.
Blood is composed of formed elements—erythrocytes, leukocytes, and cell fragments called platelets—and a fluid extracellular matrix called plasma. The information they provide is essential to the primary care providers in determining a diagnosis and in monitoring the course of a disease and response to treatment.
When more than a few drops of blood are required, phlebotomists perform a venipuncture, typically of a surface vein in the arm.
They perform a wide variety of tests on various body fluids, including blood. What types of measurements are given for levels of glucose in the blood? They perform a capillary stick on a finger, an earlobe, or the heel of an infant when only a small quantity of blood is required.
After collection, the blood may be analyzed by medical laboratories or perhaps used for transfusions, donations, or research. These include various electrolytes, such as sodium, potassium, and calcium ions; dissolved gases, such as oxygen, carbon dioxide, and nitrogen; various organic nutrients, such as vitamins, lipids, glucose, and amino acids; and metabolic wastes.Chapter 1: Foundations of Human Anatomy and Physiology Lesson - The Language of Anatomy and Physiology.
