Antibiotics are medications used to treat bacterial infections. They work by either killing bacteria or inhibiting their growth. They are available in many forms, including tablets, capsules, liquids, creams, and injections. Antibiotics can be classified into two broad categories: broad-spectrum antibiotics and narrow-spectrum antibiotics. Broad-spectrum antibiotics are effective against a wide range of bacteria, while …

1. Computerized Tomography (CT) Scan: This imaging tool uses X-rays and a computer to create detailed cross-sectional images of the body. It is often used to diagnose cancer, detect internal injuries, and assess heart and lung conditions. 2. Magnetic Resonance Imaging (MRI): This imaging tool uses a strong magnetic field and radio waves to create …
Immunization is the process by which an individual’s immune system is stimulated to develop immunity to a specific disease or set of diseases. Immunization involves the administration of a vaccine, which contains antigens (substances that stimulate an immune response) that mimic the disease-causing organism, thus stimulating the body to produce antibodies (immune molecules) against the …
The lymphatic system is a network of tissues and organs that help the body fight against infection and disease. It is part of the body’s immune system and includes the lymph nodes, tonsils, thymus, spleen, and bone marrow. These organs and tissues produce, store, and carry white blood cells that fight infection and other diseases. …
T-lymphocytes are a type of white blood cell that is a part of the immune system. They are responsible for helping the body fight off infections and diseases. They are also involved in the regulation of immune responses and the body’s defences against foreign substances. T-lymphocytes are divided into two main categories: helper T-cells and …
B-lymphocytes, also known as B-cells, are a type of white blood cell that is responsible for producing antibodies and playing a major role in the adaptive immune system. B-cells can recognize and respond to antigens and pathogens, binding to them to signal other components of the immune system to respond. B-cells also play an important …
Lymphocytes, also known as white blood cells or warrior cells, are a type of immune cell that are responsible for fighting infection. They are the most abundant type of white blood cell and are divided into two main types: B-cells and T-cells. B-cells make antibodies that recognize and attack foreign invaders, while T-cells directly attack …
