Naturally acquired passive immunity would involve the?
Placental transfer of antibodies
What is the difference between active immunity and passive immunity?
Active immunity: being infected by a live antigen (bacteria/virus) active immunity can be developed through a vacciation. Passive immunity: due to aquiring pre-formed antibodies from another individual
A redox reaction involves the transfer of?
carbon dioxide New: electrons
What is the concept of immunity?
Immunity is generally a resistance to ailments and infections. Some people are bless with naturally good immune systems, while others are not so lucky and suffer from allergies as well as from ailments. The immune system can be fired up by taking small quantities of the threatening disease so that the body gets used to fighting it; that's the principle behind 'flu shots etc.
Which phrase best describes the electron transport chain in photosynthesis?
Yes. Photosynthesis involves the transfer of electrons. Photosynthesis causes a chemical change. All chemical changes involve either the transfer of electrons or a change in the configuration of electrons. No other way exists to make a chemical change.
What is specific immunity?
specificity the quality of having a certain action, as of affecting only certain organisms or tissues, or reacting only with certain substances, as antibodies with certain antigens (antigen specificity).
Naturally acquired passive immunity would involve the?
Placental transfer of antibodies
How do you obtain passive immunity?
Passive immunity is the transfer of active humoral immunity in the form of readymade antibodies, from one individual to another. Passiveimmunity can occur naturally, when maternal antibodies are transferred to the fetus through the placenta, and can also be induced artificially, when high levels of human (or horse) antibodies specific for a pathogen or toxin are transferred to non-immune individuals. Passive immunization is used when there is a high risk of infection and insufficient time for the body to develop its own immune response, or to reduce the symptoms of ongoing or immunosuppressive diseases.
What happens in passive immunity?
A mother may transfer some IgG antibodies passively through the placenta to the fetus.
How do you acquire passive immunity?
You can get passive immunity through a placenta when you are a fetus in your mothers womb or you can be injected with antibodies that have most likely been forced to grow due to somebody putting a disease in an animal such as a rabbit. Unfortunately passive immunity does not last very long because the antibodies are detached from their white blood cells which keeps them a live and also stores the antibodies in their memory so you can not become immune forever via passive immunity as it is only passive e.g. short lived/quick
Are vaccinations examples of natural passive immunity?
No, vaccinations are examples of artificial passive immunity. Natural passive immunity is passed from mother to infant either through breastmilk, or while the fetus is in utero with the transfer of antibodies from the mother through the placenta.
How are natural acquired immunity and artificial acquired immunity alike?
Natural acquired immunity is when your body already knows how to defend against certain antigens and germs. Artificial acquired immunity is provided in shots to the body when we are babys. These shots contain inactive or a weakened antigen or germ in order to allow are body to produce an anti-body to defend against them if we were to get infected in the future. This makes them alike because the way of defending against the antigens are the same. The only difference is that in artificial immunity are bodys are introduced to a foreign antibody in order for our body to "learn" to defend against it.
What kind of immunity do you receive from vaccines?
Innate immunity (also called nonspecific or natural immunity) refers to the inborn ability of the body to resist and is genetically transmitted from one generation to the next. This immunity offers resistance to any microorganism or foreign material encountered by the host. It includes general mechanisms inherited as part of the innate structure and function of each vertebrate and acts as the first line of defense. Innate immunity lacks immunological memory, i.e., it occurs to the same extent each time a microorganism or foreign material is encountered.
Compare passive immunity to active immunity?
Active Immunity - Vaccines are used for health purposes to expose our bodies to a particular antigen. These antigens are usually killed or severely weakened to decrease their potency. After destroying these pathogens, the body stores some T cells as memory cells, due to the fact they code for a particular antigen and can be when needed. This memory in T cells can be a means of artificially acquiring immunity while a genuine attack by a pathogen is a naturally acquired type of immunity. Passive Immunity - This is where immunity to particular antigens as a result of genetic traits passed on from parents rendering the offspring immune to a particular pathogenic threat.

What is the direct transfer of antibodies from donor to recipient called?
Transfusion
How can antibodies be transferred from a woman to a fetus and a baby?
As found in Wikipedia Maternal passive immunity is a type of naturally acquired passive immunity, and refers to antibody-mediated immunity conveyed to a fetus by its mother during pregnancy. Maternal antibodies (MatAb) are passed through the placenta to the fetus by an FcRn receptor on placental cells. This occurs around the third month of gestation.[2] Immunoglobulin G is the only antibody isotype that can pass through the placenta.[2] Immunization is often required shortly following birth to prevent diseases such as tuberculosis, hepatitis B, polio, and pertussis, however, maternal antibodies can inhibit the induction of protective vaccine responses throughout the first year of life. This effect is usually overcome by secondary responses to booster immunization.[3] Passive immunity is also provided through the transfer of IgA antibodies found in breast milk that are transferred to the gut of the infant, protecting against bacterial infections, until the newborn can synthesize its own antibodies.[4] The Maternal Antibodies transferred have a half-life of approximately 14 days, and thus only have an effect for the first months.
