Biology

Biology is the branch of science that primarily deals with the structure, function, growth, evolution, and distribution of organisms. It’s a methodological study of life and living things.

Biology is the scientific study of life. It spans multiple levels, from biomolecules and cells to organisms and populations12. All living things share common biological phenomena, such as reproduction, cell division, and the transmission of genetic material.

Connective tissue characteristics, functions and types

Connective tissue: characteristics, functions and types

What is connective tissue? Connective tissue is a vital tissue type found throughout the human body, with roles that range from providing structural support to connecting organs and tissues. It also plays an essential part in nutrient transportation and immune defense. Let’s explore the key characteristics, functions, and various types of supporting tissue. Key Characteristics […]

Muscular tissue: skeletal, smooth and cardiac muscle

What is Muscular Tissue? Muscular tissue is crucial for movement and function within the human body. It enables actions like walking, breathing, pumping blood, and digesting food. There are three main types of muscle tissue: skeletal muscle, smooth muscle, and cardiac muscle. Each type of muscular tissue is uniquely structured and serves specific functions. Let’s

Cells of immune system Lymphocytes, phagocytic cell, granulocytes and dendritic cells

Cells of immune system: Lymphocytes, phagocytic cell, granulocytes and dendritic cells

Introduction The immune system is the body’s natural defense against harmful invaders like bacteria, viruses, and parasites. It relies on several specialized cells to detect, destroy, and remove these threats. These immune system cells can be grouped into four main types: lymphocytes, phagocytic cells, granulocytes, and dendritic cells. Each plays a unique and essential role

Phagocytosis or Phagocytic barrier of immune system

Phagocytosis or Phagocytic barrier of immune system

What is Phagocytosis? Phagocytosis is the process by which immune cells engulf and digest harmful materials such as pathogens, dead cells, and other debris. This process is essential for eliminating invaders and preventing infections from spreading. The immune system uses various defense mechanisms to protect the body from harmful invaders like bacteria, viruses, and other

VDRL test: Principle, Procedure, Result interpretation and Application

What is VDRL test? The VDRL test (Venereal Disease Research Laboratory test) is a blood test used to screen for syphilis, a sexually transmitted infection caused by the bacterium Treponema pallidum. It’s a type of non-treponemal test, meaning it identifies antibodies produced by the body in response to cell damage caused by syphilis, rather than

Normal flora of human host: Types, Examples and Roles

What is Normal Flora? Normal flora, also known as microbiota, refers to the community of microorganisms like bacteria, fungi, and viruses that naturally live on or inside the human body without causing disease. These microbes inhabit different parts of the body, including the skin, mouth, gut, respiratory system, and reproductive organs. While microorganisms are often
