    Recall that blood is a connective tissue. Like all connective tissues, it is made up of cellular elements and an extracellular matrix. The cellular elements—referred to as the formed elements —include red blood cells (RBCs), white blood cells (WBCs), and cell fragments called extracellular matrix, called plasma, makes blood unique among connective . Of course, the heart does not function in isolation; it is part of a system composed of blood and blood vessels as well. The highest level of body organization, then, is that of the organ system. Learn how a failure in the endocrine system may affect digestive, circulatory, and excretory systems A discussion of the organ systems of the human.

    Blood cells (formed elements) are of three types namely, 1. Red blood cells (RBC’s or erythrocytes) 2. White blood cells (or leukocytes) and. 3. Platelets (or thrombocytes). 1. Red blood cells (RBC’s) have a respiratory pigment called “haemoglobin.” The haemoglobin molecules occupy about 1/3 rd of the volume of an RBC. The remaining. COVID Resources. Reliable information about the coronavirus (COVID) is available from the World Health Organization (current situation, international travel).Numerous and frequently-updated resource results are available from this ’s WebJunction has pulled together information and resources to assist library staff as they consider how to handle .

    Function of Red Blood Cells. This article mulls on the crucial function of red blood cells. Red blood cells formed in the bone marrow have a short lifespan of only - days, within which they perform the crucial role of transporting oxygen to various parts of the body.

Blood transports oxygen and nutrients around the body and removes cellular waste, among a range of other vital functions. Plasma makes up 55 percent of blood content. Without blood, tissues may undergo hypoxia, ischemia, or infarction depending on the severity of the deficiency.

The blood is involved in the homeostasis of variables such as temperature, blood volume, blood pressure, blood pH, and blood glucose levels. Other important blood functions include carbon dioxide transport and hormone signaling. The enlarging tissues, and disruption of blood's functions, can eventually cause organ failure.

Anemia: An abnormally low number of red blood cells in the blood. Oxygen is vital to life as it provides fuel for all the body's functions. The heart's role is to pump oxygen-rich blood to every cell in the body. The blood vessels — a network of interconnecting arteries, arterioles, capillaries, venules, and veins — provide the pathway in which blood travels.

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. We have seen blood consist of cells known as formed elements of blood. These cells have their own functions and roles to play in the body.

The blood cells which circulate all around the body are as follows: Red blood cells (Erythrocytes) RBCs are the biconcave cells and without nucleus in humans; also known as erythrocytes.

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. In vertebrates, it is composed of blood cells suspended in bloodwhich constitutes 55% of blood fluid, is mostly water (92% by volume), and contains proteins.

Recall that blood is a connective tissue. Like all connective tissues, it is made up of cellular elements and an extracellular matrix. The cellular elements—referred to as the formed elements—include red blood cells (RBCs), white blood cells (WBCs), and cell fragments called extracellular matrix, called plasma, makes blood unique among connective.

Blood: Its Composition and Function The blood in our circulatory system is a watery based fluid and consists of two basic components: 1) Plasma (55%) and, 2) Formed elements (45%) Part A: Plasma The Plasma is the light yellow liquid portion of the blood and is about 90% water.

Dissolved in the plasma are:File Size: KB. White blood cells. The white blood cells, which are also called leukocytes (leuko = white), are involved in functions controlled by the immune immune system is responsible for fighting infections.

If a person has a low white blood cell count, it means that the immune system is not functioning properly. Veins as Blood Reservoirs. In addition to their primary function of returning blood to the heart, veins may be considered blood reservoirs, since systemic veins contain approximately 64 percent of the blood volume at any given time ().Their ability to hold this much blood is due to their high capacitance, that is, their capacity to distend (expand) readily to store a high volume of blood.

Without these, our blood would be flowing in every direction possible. What is the function of the blood vessels. The main function of blood vessels is to carry blood through the body.

The blood carries oxygen, nutrients, and wastes that need to circulate the body. The three kinds of blood vessels are: arteries, veins, and capillaries. A complete blood count (CBC) test gives your doctor important information about the types and numbers of cells in your blood, especially the red blood cells and their percentage (hematocrit) or protein content (hemoglobin), white blood cells, and platelets.

The results of a CBC may diagnose conditions like anemia, infection, and other platelet count and plasma. Functions of the Heart. Pumping blood is the chief and only function of the heart.

Freshly oxygenated blood from the lungs enter the heart which is then pumped out to the rest of the body. After delivering oxygen to all tissues, the de-oxygenated blood returns to the heart, which the heart sends back to the lungs to get re-charged with oxygen. The endothelium, a monolayer of endothelial cells, constitutes the inner cellular lining of the blood vessels (arteries, veins and capillaries) and the lymphatic system, and therefore is in direct contact with the blood/lymph and the circulating cells.

The endothelium is a major player in the control of blood fluidity, platelet aggregation and vascular tone, a major actor in the regulation. Volume of blood plasma is approximately l ( ml/kg of b.w.). Together with the lymph, it makes up to 25 % of extracellular fluid (ECF).

Basic functions of blood include: 1) Transport of nutrients, waste products, blood gases (oxygen and carbon dioxide) or signaling molecules. 2) Immune function. 3) To maintain homeostasis of water.

Function Messenger and waste removal. Blood is the most important transport medium in the human body. It transports gases (oxygen, carbon dioxide, nitrogen etc.) as well as nutrients (metabolism) and end products of cell the blood has the task of assuring the exchange of substances.

Identify the primary functions of blood, its fluid and cellular components, and its physical characteristics; Identify the most important proteins and other solutes present in blood plasma; Describe the formation of the formed element components of blood; Discuss the structure and function of red blood cells and hemoglobin.

The book discusses the minute morphology of various blood-cells; the fundamental basis of hemopoiesis of human; and the purpose of the bone marrow as a red-cell factory.

Some of the topics covered in the text are the structures of lymphocytes; the production and functions of neutrophile leucocyte; and the chemical characters of cells.

The function of the heart in any organism is to maintain a constant flow of blood throughout the body. This replenishes oxygen and circulates nutrients among the cells and tissues.

Also, because the human heart is a homologous organ, it functions no differently from any other vertebrates that possess a heart. The liver is the largest solid organ in the human body. It performs essential tasks, including detoxification, protein synthesis, and the production of .Blood pumped by the heart flows through a series of vessels known as arteries, arterioles, capillaries, venules, and veins before returning to the heart.

Arteries transport blood away from the heart and branch into smaller vessels, forming arterioles. Arterioles distribute blood to capillary beds, the sites of exchange with the body tissues.Additional Physical Format: Online version: Macfarlane, Gwyn, Functions of the blood.
