The macrophage is a large white blood cell within the immune system.A macrophage is an amoeba-type cell and they are produced from white blood cells called monocytes, which are formed by stem cells within the bone marrow. Monocytes passes through the bloodstream and when they leave the blood, they mature and become macrophages. It is responsible to locate microscopic foreign bodies and to engulf them. Macrophages use the process of phagocytosis to engulf particles and then digest them.

The process commences by the macrophage engulfing the particle/microorganisms, leading to the formation of a pocket called a phagosome around it.Then the organelle lysosome releases enzymes into the phagosome, to digest the particle/microorganism.The remaining

Summary: The Innate Immune System

The system produces a number of substances include cationic antimicrobial peptides (CAMPs) such as defensins, bacteriolytic enzymes such as lysozyme etc. The production of these substances ensures that the microorganisms are destroyed before they get an opportunity to cause infections [4]. However, S. aureus has developed mechanisms, which enhance the evasion of the host immune system. The host’s body produces effector proteins after microbial invasion; nevertheless, S. aureus produces molecules that inhibit these proteins. Another mechanism used by the microbe involves binding of immune regulators produced by the host through the production of surface-bound molecules [5, 6].…

Thrombopoiesis produces the platelets and begins with a myeloid stem cell, which produces the progenitor cell when stimulated and becomes a megakaryoblast. The megakaryoblast responds to the hormone thrombopoietin and forms a megakaryocyte. The platelets are formed when small, membrane bound portions of cytoplasm break away. Leukopoiesis is the formation of white blood cells.…

Why Transport Systems Are Required In The Body

A) Explain why transport systems are required in the body? The reasons as to why transport systems are required in the body is because it allows the body to be able to respire and be able to get all that it needs to maintain the same state, for example, oxygen throughout the body as well as nutrients to the cells in the body. An example of a transport system is the Respiratory system. This system is required in the body as it helps the body to take in oxygen, this can be done through the lungs, as it allows it to be absorbed into the blood, through the use of the alveolus found within the tissue of the lungs, in order to provide energy for the cells in the body to keep functioning as well as developing.…

Specialised Nerve Impulses

Granulocytes have granules which are located in the cytoplasm, they can also change their shape, engulf microbes and foreign material like bacteria, they are very important as they protect the body from infection. Lymphocytes are another form of white blood cells that are significant in the immune system; they are smaller than granulocytes, contain a nucleus and a clear cytoplasm. The lymphocytes produce antibodies, these antibodies neutralise the antigens, which are found on the surface of a microbe or pathogen giving them an identity for the body to remember, to stop them from multiplying. Another type of white blood cells includes Monocytes, monocytes are larger than lymphocytes and contain a large nucleus that is round and has a clear cytoplasm.…

The Four Macromolecules In Living Organisms

The four macromolecules present in all living organisms are carbohydrates, lipids, proteins, and nuclear acids (Daempfle, 2016). Carbohydrates provide energy. Like carbohydrates, the main function of lipids is to store energy long-term. Proteins are the most common macromolecule in livings systems; they play various roles in our bodies from hair, nails, and skin to having functions in chemical reactions within cells. Nucleic acids play a vital role in the formation of proteins which perform many essential functions for cells.…

Primary Immune Response Paper

The immune system is made up of different parts that are constantly protecting the body from disease-causing microorganisms known as pathogens. By keeping out these infectious pathogens out of the body or destroying the pathogens that do enter the body, the immune system is a complex network of cells and organs that protect the body from infection. The primary immune response is the response that is activated when the body is first exposed to an antigen, resulting in the activation of lymphocytes. If the human body is encounters the same antigen again, the secondary immune response is activated.…

Microfilaments Function

There are a lot of functions that microfilaments do. The first of them is the organization of the plasma membrane which give shape to surface structures such as microvilli. Microfilaments can exist as a tight bundle of filaments making up the core of the slender, fingerlike microvilli. Microfilaments can function on their own or serve as tracks for ATP-powered myosin motor proteins, which provide a contractile function (as in muscle) along microfilaments. Specialized cells such as macrophages use contractile microfilaments to engulf and internalize pathogens, which are then destroyed internally.…
