Blood - Wikipedia. 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.[1]In vertebrates, it is composed of blood cells suspended in blood plasma. Plasma, which constitutes 5. Albumin is the main protein in plasma, and it functions to regulate the colloidal osmotic pressure of blood. The blood cells are mainly red blood cells (also called RBCs or erythrocytes), white blood cells (also called WBCs or leukocytes) and platelets (also called thrombocytes).

The most abundant cells in vertebrate blood are red blood cells. These contain hemoglobin, an iron- containing protein, which facilitates oxygen transport by reversibly binding to this respiratory gas and greatly increasing its solubility in blood. In contrast, carbon dioxide is mostly transported extracellularly as bicarbonate ion transported in plasma. Vertebrate blood is bright red when its hemoglobin is oxygenated and dark red when it is deoxygenated. Some animals, such as crustaceans and mollusks, use hemocyanin to carry oxygen, instead of hemoglobin. Insects and some mollusks use a fluid called hemolymph instead of blood, the difference being that hemolymph is not contained in a closed circulatory system. In most insects, this "blood" does not contain oxygen- carrying molecules such as hemoglobin because their bodies are small enough for their tracheal system to suffice for supplying oxygen.

Jawed vertebrates have an adaptive immune system, based largely on white blood cells. White blood cells help to resist infections and parasites. Platelets are important in the clotting of blood. Arthropods, using hemolymph, have hemocytes as part of their immune system. Blood is circulated around the body through blood vessels by the pumping action of the heart.

What Causes Nucleated Red Blood Cells In Adults

In animals with lungs, arterial blood carries oxygen from inhaled air to the tissues of the body, and venous blood carries carbon dioxide, a waste product of metabolism produced by cells, from the tissues to the lungs to be exhaled. Medical terms related to blood often begin with hemo- or hemato- (also spelledhaemo- and haemato- ) from the Greek word αἷμα (haima) for "blood".

In terms of anatomy and histology, blood is considered a specialized form of connective tissue, given its origin in the bones and the presence of potential molecular fibers in the form of fibrinogen. Functions. Hemoglobin, a globular protein.

Blood performs many important functions within the body, including: Supply of oxygen to tissues (bound to hemoglobin, which is carried in red cells)Supply of nutrients such as glucose, amino acids, and fatty acids (dissolved in the blood or bound to plasma proteins (e. Removal of waste such as carbon dioxide, urea, and lactic acid. Immunological functions, including circulation of white blood cells, and detection of foreign material by antibodies. Coagulation, the response to a broken blood vessel, the conversion of blood from a liquid to a semisolid gel to stop bleeding. Messenger functions, including the transport of hormones and the signaling of tissue damage.

Regulation of core body temperature. Hydraulic functions. Constituents. Blood accounts for 7% of the human body weight,[3][4] with an average density around 1.

The average adult has a blood volume of roughly 5 litres (1. US pt),[4] which is composed of plasma and several kinds of cells.

These blood cells (which are also called corpuscles or "formed elements") consist of erythrocytes (red blood cells, RBCs), leukocytes (white blood cells), and thrombocytes (platelets). By volume, the red blood cells constitute about 4. Whole blood (plasma and cells) exhibits non- Newtonianfluid dynamics. If all human hemoglobin were free in the plasma rather than being contained in RBCs, the circulatory fluid would be too viscous for the cardiovascular system to function effectively. Human blood fractioned by centrifugation: Plasma (upper, yellow layer), buffy coat (middle, thin white layer) and erythrocyte layer (bottom, red layer) can be seen. Blood circulation: Red = oxygenated, blue = deoxygenated.

Illustration depicting formed elements of blood. Two tubes of EDTA- anticoagulated blood. Left tube: after standing, the RBCs have settled at the bottom of the tube. Right tube: Freshly drawn blood.

Cells. One microliter of blood contains: 4. Red blood cells contain the blood's hemoglobin and distribute oxygen. Mature red blood cells lack a nucleus and organelles in mammals. The red blood cells (together with endothelial vessel cells and other cells) are also marked by glycoproteins that define the different blood types.

The proportion of blood occupied by red blood cells is referred to as the hematocrit, and is normally about 4. The combined surface area of all red blood cells of the human body would be roughly 2,0.
