This word carries a different meaning in the context of Chinese medicine than it does in standard English, often being capitalized. In TCM, blood is defined as a red liquid circulating inside the blood vessels that is a vital substance of the human body. The functions attributed to blood are nourishing and moistening the body’s tissues and organs, and providing a basis for mental activities.
A red liquid moved around the body by the pumping action of the heart.
Fluid tissue that is pumped by the heart through arteries, capillaries, and veins carrying oxygen and nutrients to body cells and carbon dioxide and other waste products away from body cells. Human blood is composed of a pale yellow fluid called plasma in which red blood cells (erythrocytes), white blood cells (leukocytes), platelets, and a variety of chemicals, including hormones, proteins, carbohydrates, and fats are suspended. Adult males have about 70 ml/kg of body weight; women, about 65 ml/kg.
The fluid that carries nutrients and oxygen to and removes wastes from all parts of the body. It also performs many other vital functions. Blood consists primarily of plasma, red blood cells, white blood cells, and platelets.
The fluid that circulates in veins and arteries throughout the body. The blood transports oxygen, nutrients, and other chemicals throughout the body to every tissue and carries away waste materials. It also defends the body against infections. Because blood loss could be so damaging, blood has the capability to help seal damaged blood vessels, create clots at the sites of injuries to stop bleeding, and help repair damaged tissue. The heart pumps the body’s blood supply in a continuous cycle through the arteries to the lungs and all other organs and tissues and then back to the heart through the veins. A typical adult’s body contains about 10 pints of blood. At rest, the heart pumps about 10 pints of blood per minute. About 55 percent of t he blood’s volume is made up of a fluid called plasma, which transports blood cells, proteins, minerals, and nutrients to the body’s tissues. The blood cells including red blood cells, white blood cells, and platelets — account for the remaining blood volume.
The fluid tissue in the human circulatory system. It consists of plasma, platelets, and blood cells.
Blood consists of cells suspended in plasma. It circulates through the blood vessels, carrying oxygen and nutrients to the organs and removing carbon dioxide and other waste products for excretion. In addition, it is the vehicle by which hormones and other humoral. transmitters reach their sites of action.
The cell-containing fluid that circulates through the heart, arteries, veins, and capillaries, carrying nourishment, electrolytes, hormones, vitamins, antibodies, heat, and oxygen to the tissues and taking away waste matter and carbon dioxide.
A tissue that is made up of cells, fluid, and other substances that carries oxygen, carbon dioxide, and nutrients in the body.
Nutritive fluid circulating through the circulatory system (heart and blood vessels) to supply oxygen and nutrients to cells and tissues and to remove carbon dioxide and waste from them.
The crimson fluid that flows through the body’s veins, arteries, and capillaries is known as blood. It is propelled by the heart through the arteries, reaching the lungs and all other tissues, and is subsequently returned to the heart via the veins. Serving as the body’s transportation system, blood also plays a vital role in defending against infections. On average, an adult possesses approximately 5 liters of this vital fluid.
Approximately half of the volume of blood comprises various types of blood cells, notably red blood cells (erythrocytes) responsible for oxygen transport to the tissues, white blood cells (leukocytes) that safeguard the body against infections, and platelets (thrombocytes) involved in the process of blood clotting. The remaining portion of the blood volume is composed of plasma, a pale yellowish fluid with a watery consistency. Plasma contains a diverse range of constituents such as proteins, sugars, fats, salts, and minerals.
Following absorption from the intestinal tract or release from storage sites like the liver, nutrients are conveyed to the body’s tissues through the bloodstream. Simultaneously, waste products, including urea and bilirubin, are transported in the plasma to the kidneys and liver, respectively, for appropriate elimination or processing.
Among the constituents of plasma are various proteins, including fibrinogen, which plays a crucial role in the process of blood clotting. Additionally, immunoglobulins (commonly known as antibodies) and complement, which are integral components of the immune system, are also present. Another significant protein found in plasma is albumin. Furthermore, hormones are transported through the bloodstream, reaching their target organs to exert their physiological effects.
The fluid that circulates through the heart, arteries, and veins, carrying nutriment and oxygen to the body tissues. Blood is composed of a clear yellow fluid, the plasma, containing the erythrocytes (red blood cells), the leukocytes (white blood cells), and the thrombocytes (blood platelets). The erythrocytes contain hemoglobin, a red oxygen-carrying chemical. The leukocytes have various functions. They assist in the repair of injured tissues of blood and are part of the body’s defense against infection. When germs enter the body, the leukocytes rush to the scene, then engulf and destroy the germs. The thrombocytes assist in the coagulation of the blood. Blood is formed in the marrow of the long bones, and, varying with the size of the individual, the body contains six to twelve pints. An adult can lose two pints of blood without ill effect, larger losses producing severe surgical shock and collapse. One cubic millimeter of blood contains between four and five million erythrocytes (each of which has a diameter of seven-thousandths of a millimeter), four to eleven thousand leukocytes, and up to five hundred thousand thrombocytes. Blood circulates under the pressure of the heart pump equivalent in the healthy adult to 120 millimeters of mercury. A drop of blood takes from nine to sixteen seconds to travel from the arm to the tongue and from four to eight seconds to travel from the arm to the lung.
