Blood is a body fluid in humans and other animals that delivers necessary substances such as nutrients and oxygen to the cells and transports metabolic waste products away from those same cells.

The composition of tissue fluid depends upon the exchanges between the cells in the biological tissue and the blood. This means that fluid composition varies between body compartments. The cytosol or intracellular fluid consists mostly of water, dissolved ions, small molecules, and large, water-soluble molecules such as proteins. This mixture of small molecules is extraordinarily complex, as the variety of enzymes that are involved in cellular metabolism is immense.

Components of Blood

Clinical Management of Electrolyte Disorders pp Cite as. Body fluid consists of an aqueous solution of salts, proteins and carbohydrates. Some of this solution is within cell membranes intracellular fluid and some is outside the membranes extracellular fluid. Although differing in concentration of certain ions, especially sodium and potassium, the composition of the intracellular and extracellular fluids remains very constant in health. Fluid similar in composition to extracellular fluid circulates through the blood vessels and lymphatics, carrying the products of cell metabolism from their point of origin to their point of excretion through the lungs, liver, kidneys and bowel.

The liquid component of the blood in which the following blood cells are suspended:. Red blood cells erythrocytes. These carry oxygen from the lungs to the rest of the body. White blood cells leukocytes. These help fight infections and aid in the immune process. Types of white blood cells include:.

When a sample of blood is spun in a centrifuge , the cells and cell fragments are separated from the liquid intercellular matrix. Because the formed elements are heavier than the liquid matrix, they are packed in the bottom of the tube by the centrifugal force. The light yellow colored liquid on the top is the plasma , which accounts for about 55 percent of the blood volume and red blood cells is called the hematocrit ,or packed cell volume PCV. The white blood cells and platelets form a thin white layer, called the " buffy coat ", between plasma and red blood cells. The watery fluid portion of blood 90 percent water in which the corpuscular elements are suspended. It transports nutrients as well as wastes throughout the body. Various compounds, including proteins, electrolytes , carbohydrates, minerals, and fats, are dissolved in it.

What is the function of blood?

Find GPs in Australia. The formed elements are so named because they are enclosed in a plasma membrane and have a definite structure and shape. All formed elements are cells except for the platelets, which are tiny fragments of bone marrow cells. Leukocytes are further classified into two subcategories called granulocytes which consist of neutrophils, eosinophils and basophils; and agranulocytes which consist of lymphocytes and monocytes. The formed elements can be separated from plasma by centrifuge, where a blood sample is spun for a few minutes in a tube to separate its components according to their densities. This volume is known as the haematocrit. WBCs and platelets form a narrow cream-coloured coat known as the buffy coat immediately above the RBCs.

Blood , fluid that transports oxygen and nutrients to the cells and carries away carbon dioxide and other waste products. Technically, blood is a transport liquid pumped by the heart or an equivalent structure to all parts of the body, after which it is returned to the heart to repeat the process. Blood is both a tissue and a fluid. It is a tissue because it is a collection of similar specialized cells that serve particular functions. These cells are suspended in a liquid matrix plasma , which makes the blood a fluid.

ГЛАВА 33 Токуген Нуматака смотрел в окно и ходил по кабинету взад-вперед как зверь в клетке. Человек, с которым он вступил в контакт, Северная Дакота, не звонил. Проклятые американцы. Никакого представления о пунктуальности. Он позвонил бы Северной Дакоте сам, но у него не было номера его телефона. Нуматака терпеть не мог вести дела подобным образом, он ненавидел, когда хозяином положения был кто-то. С самого начала его преследовала мысль, что звонки Северной Дакоты - это западня, попытка японских конкурентов выставить его дураком.

Сдвинув в сторону пустые пивные бутылки, Беккер устало опустил голову на руки. Мне нужно передохнуть хотя бы несколько минут, - подумал. В нескольких милях от этого места человек в очках в железной оправе сидел на заднем сиденье фиата, мчавшегося по проселочной дороге. - Клуб Колдун, - повторил он, напомнив таксисту место назначения. Водитель кивнул, с любопытством разглядывая пассажира в зеркало заднего вида.

ГЛАВА 115 В голове Дэвида Беккера была бесконечная пустота. Я умер.

    A significant percentage of the human body is water, which includes intracellular and extracellular fluids.
