The document compares and contrasts the two main types of immune response: innate and adaptive. The innate immune response provides an immediate but non-specific first line of defense. In contrast, the adaptive immune response requires time to activate but has highly specific and long-lasting memory against pathogens. Together, the innate and adaptive immune responses work closely to destroy foreign invaders in the body.

Immunity
This document discusses different types of immunity, including innate immunity, acquired immunity, natural immunity, and artificial immunity. It describes innate immunity as genetic and not related to previous infections or immunizations, acting as the first line of defense through anatomical, physiological, chemical, and biological barriers. Acquired immunity is initiated through antigen recognition and involves lymphocytes, antigen presenting cells, and the development of immunological memory to distinguish self from non-self. Active immunity develops from natural infection or artificial vaccination, while passive immunity involves the transfer of antibodies from an immunized donor to a non-immunized recipient, either naturally or artificially.
Immunity ppt
The document discusses various topics related to human immunity, including:
1. It describes the two main types of immunity - innate (nonspecific) immunity which acts as the first line of defense, and acquired (specific) immunity which is adaptive and involves lymphocytes and antigen presenting cells.
2. Within acquired immunity, it distinguishes between natural active immunity gained from infection and artificial active immunity gained from vaccines.
3. The two main branches of acquired immunity are humoral immunity involving antibodies, and cell-mediated immunity involving T cells that recognize antigens on cell surfaces.
4. It provides details on the structure and functions of the main antibody classes - IgG, IgM, IgA, IgD
Y8 Humans 13 two types of immunity
There are two types of immunity: active and passive. Active immunity occurs when the body produces its own antibodies after exposure to an antigen, either from natural infection or vaccination. Passive immunity occurs when antibodies are transferred to a person, rather than being produced by their own immune system, such as antibodies passed from mother to fetus or through antibody administration. Vaccines work by introducing a weakened or dead form of a pathogen to trigger antibody production and provide immunity without causing disease.
Natural and Acquired Immunity
This document summarizes the key differences between natural (innate) immunity and acquired (adaptive) immunity. Natural immunity is inborn and provides non-specific protection against pathogens through physical and chemical barriers like skin and mucous membranes. It also includes phagocytic cells that engulf and destroy pathogens. Acquired immunity develops over time after exposure to specific pathogens and antigens. It produces targeted immune responses through antibodies and T cells that provide long-lasting, pathogen-specific protection. The document compares the mechanisms, characteristics, components and responses of natural versus acquired immunity.

Haptens
Antigen is substance which when introduced parentally into the body stimulates the production of an antibody with which it reacts specifically and in an observable manner.
CLASSIFICATION OF ANTIGENS
Based on Immunogenicity
Complete antigen : substances with both immunogenicity and immunoreactivity Incomplete antigen
Incomplete antigen ( hapten): substances only with immunoreactivity
Hapten +carrier → complete antigen
( Immunogenicity : induction of immune response
• Immunological Reactivity: specific reaction with antibodies or sensitized cells)
HAPTENS
The term Hapten was given by the immunologist Karl Landsteiner, who studied them in early 20th century.
• It came from a Greek word Haptein meaning to fasten.
DEFINITION OF HAPTENS
Small, non-biologic molecules that bind to immune cells receptors but cannot by themselves induce a specific immune response
That are antigenic but not immunogenic Which means that they can bind to immune cells but fail to induce Humoral or cell mediated immune response. Hence no antibodies are raised against them

TYPES OF IMMUNITY
This document discusses the different types of immunity. It begins by defining immunity and describing the innate immunity system, which includes anatomical barriers like skin and mucous membranes, physiological barriers like low pH levels, and biological barriers like white blood cells. The document then explains acquired immunity, noting it is antigen specific, diverse, leads to immunological memory, and involves self/non-self recognition. Acquired immunity is divided into active immunity, which occurs from natural exposure or vaccination, and passive immunity, which results from transfer of antibodies or immune cells from another individual. Both active and passive immunity can be naturally acquired or artificially acquired.
Immunity THE BODY’S DEFENSES
The document discusses the body's defense mechanisms against disease. It describes three lines of defense: external barriers like skin and mucus, internal barriers like stomach acid, and the immune system. The immune system uses nonspecific defenses like phagocytes and the inflammatory response. It also has specific immune defenses like antibodies and lymphocytes. Antibodies provide humoral immunity while lymphocytes provide cell-mediated immunity. The document also covers immune system disorders like allergies and AIDS.
What is Immunity? Explain the types of Immunity? (Presentation)
The document provides an overview of immunology, including definitions and key concepts. It discusses the immune system's innate and acquired immunity. Innate immunity provides immediate protection through physical barriers, chemicals, proteins and cells. Acquired immunity develops from exposure through active immunity from natural infection or vaccination, or passive immunity from maternal antibodies or antibody treatments. The immune system uses recognition and response to protect against pathogens through a variety of interrelated components.
Mechanisms Of Defense Immune System.ppt
The immune system protects the body from pathogens and tumor cells. It has both innate and adaptive defenses. The adaptive immune system includes B cells and T cells. B cells produce antibodies while T cells help regulate immune responses. Memory cells allow for a faster response upon reexposure to pathogens. Dysregulation can lead to autoimmunity or immunodeficiency. Factors like stress and emotions can also influence immune function.
Immune system physiology, Three Defense Mechanisms of Human Body
The adaptive immune system has four defining characteristics: self/non-self recognition, specificity, diversity, and memory. B and T lymphocytes recognize antigens through surface receptors and respond by dividing into effector cells that combat infection, and memory cells that remember each antigen. The antibody-mediated response involves B cells producing antibodies against extracellular pathogens, while the cell-mediated response uses cytotoxic T cells and natural killer cells to destroy infected or abnormal body cells.
Bio 151 lec 3 2012 2013
This document summarizes innate immunity. It discusses how innate immunity provides a first line of defense through mechanisms that are always active and non-specific, such as physical barriers and cellular responses. Components of innate immunity include epithelial barriers, phagocytes, natural killer cells, the complement system, and inflammatory cytokines. These components work together to recognize microbes, initiate inflammation, opsonize pathogens, and eliminate infections before they can become established.

Active immunity can be natural from infection or artificial from vaccines. Passive immunity transfers ready-made antibodies from mother to child or through antibody administration. Local and herd immunities provide community-level protection.
Presentation 11 - Immunity
The document summarizes key concepts of the human immune system. It describes both innate, nonspecific defenses like skin barriers and phagocytes, as well as acquired, specific defenses mediated by lymphocytes and antibodies. The immune system protects against pathogens through both humoral responses involving B cells and antibodies, and cell-mediated responses involving T cells. Memory responses provide faster protection upon reexposure to pathogens.
Types of immunity
This document summarizes the different types of immunity. There are two main types: innate (non-specific) immunity, which is the body's first line of defense and does not depend on previous exposure; and acquired (adaptive/specific) immunity, which develops over time after exposure and retains memory to mount a stronger response next time. Innate immunity includes physical barriers and cellular barriers like phagocytes and cytokines. Acquired immunity consists of antibody-mediated (humoral) immunity and cell-mediated immunity, and can be actively or passively acquired through natural infection or vaccination.
Immunity
Immunity refers to the body's resistance to microorganisms and their products. There are two main types of immunity: innate immunity which is inborn resistance, and acquired immunity which is developed during life. Acquired immunity has two further types - active immunity developed from antigen exposure, and passive immunity which involves transmission of readymade resistance from another source.

Unemployment econ
Unemployment is defined as individuals actively seeking jobs but remaining unhired, expressed as a percentage of the total workforce. It varies with economic conditions and other circumstances. Nationally, unemployment is caused when the economy slows and businesses cut costs by reducing payrolls, or due to industry competition and advanced technology replacing workers. In the Philippines, the unemployment rate decreased from 7% to 6.8% in the third quarter of 2012, historically averaging 9.14% from 1994 to 2012. The National Capital Region had the highest unemployment rate at 11%, while Cagayan Valley had the lowest at 2.4%.
Inflation econ
- Inflation occurs when prices for most goods and services rise over time, reducing people's standard of living since each dollar buys less. Mild inflation of around 2% can encourage economic growth by prompting people to purchase goods sooner.
- There are three main causes of inflation: demand-pull inflation from rising demand outstripping supply; cost-push inflation from restricted supply despite stable demand, which can lead to wage inflation; and overexpansion of the money supply creating excess liquidity.
- According to the National Statistics Office, inflation in the Philippines rose slightly to 3.0% in January 2013, at the low end of the government's 3-5% target range for the year, with food, electricity
serology and immunology
Serology and immunology laboratories focus on identifying antibodies and investigating immune system problems. Common tests determine tumor markers, hormones, diseases, organ compatibility, and immune system deficiencies. Specimens usually require serum, but some tests use plasma with anticoagulant citrate. Test results aid doctors in diagnosing diseases.
demographic and population control policies
Factors that determine a country's population size include birth rates, death rates, immigration, and emigration. Birth rates are influenced by nutrition, fertility, abortion policies, economic factors, and culture. Death rates are affected by disease, war, healthcare access, and development levels. Immigration and emigration depend on "pull" and "push" factors that attract or displace people. Governments implement population policies to manage these factors.
overview of plant structure
Vascular plants have three main organs: roots, stems, and leaves. Roots function to anchor the plant and absorb water and minerals, stems support leaves and reproductive structures, and leaves are the primary photosynthetic organ. These organs work together through vascular tissue to transport water, minerals, and food between roots, stems, and leaves. Roots absorb water and minerals which are carried by xylem to leaves, while leaves produce food through photosynthesis which is carried by phloem to the rest of the plant.
redox reaction
This document discusses chemical reactions and energy changes. It explains that chemical bonds contain potential energy and energy can be released or absorbed as bonds are broken or formed in reactions. It defines oxidation as the loss of electrons and reduction as the gain of electrons. As an example, it shows the redox reaction of methane and oxygen producing carbon dioxide, energy, and water, with methane undergoing oxidation and oxygen undergoing reduction.
Oogenesis and fertilization report
Oogenesis is the process where egg cells, or ova, develop in the ovaries. During fetal development, early egg cells known as primary oocytes form but stop dividing until puberty. Just before ovulation, primary oocytes complete the first meiotic division to form secondary oocytes. Upon fertilization by sperm, secondary oocytes complete the second meiotic division to form a single cell called a zygote containing genetic material from both parents. Fertilization involves sperm undergoing changes to penetrate the secondary oocyte, and the union of the sperm and oocyte nuclei to combine their chromosomes and form a new individual.
