Answer 1

Immunoglobulin and plasma cells are examples of adaptive defense, while keratinized epithelium and stratified squamous epithelium are examples of innate defense. Complement (antibody-dependent pathway) involves a collaboration between innate and adaptive immunity. Major histocompatibility complexes play a role in both innate and adaptive immunity.

Step-by-step explanation:

The immune system has both adaptive and innate forms of defense. Let's determine which label identifies which form of defense:

1. Immunoglobulin: Immunoglobulins are antibodies produced by plasma cells. Antibodies are part of the adaptive immune response, so immunoglobulins are an example of adaptive defense.
2. Plasma cells: Plasma cells are immune cells that secrete antibodies, which are part of the adaptive immune response. Therefore, plasma cells are an example of adaptive defense.
3. Keratinized epithelium: Keratinized epithelium is a type of stratified squamous epithelium found in the skin. An intact skin barrier is part of the innate defense mechanism.
4. Stratified squamous epithelium: Stratified squamous epithelium is a type of epithelial tissue that forms a protective barrier. It is a form of innate defense.
5. Complement (antibody-dependent pathway): The complement system is part of the innate immune response, but the antibody-dependent pathway of complement activation involves a collaboration between the innate and adaptive immune systems.
6. Major histocompatibility complexes: Major histocompatibility complexes (MHC) are cell surface proteins that help in presenting antigens to immune cells. They are involved in both innate and adaptive immune responses.
7. Agglutinin: Agglutinins are antibodies that can bind to and clump together pathogens. They are part of the adaptive immune response.
8. Hypodermal areolar connective tissue: Hypodermal areolar connective tissue provides support and protection. It is part of the innate defense mechanism.
9. Antigen-presenting cells: Antigen-presenting cells (APCs) are immune cells that display antigens to activate T cells. They are part of the adaptive immune response.
10. Helper T cells: Helper T cells are a type of T cell that assist B cells and other immune cells in the adaptive immune response.
11. Memory T cells: Memory T cells are a type of T cell that are formed after initial exposure to an antigen. They provide long-lasting immunity in the adaptive immune response.
12. Cytotoxic T cells: Cytotoxic T cells are a type of T cell that can kill infected or cancerous cells. They are part of the adaptive immune response.
13. CD4+ cells: CD4+ cells, also known as T helper cells, are a type of T cell that help coordinate immune responses. They are involved in the adaptive immune response.
14. T lymphocytes: T lymphocytes, also known as T cells, are a type of white blood cell that play a key role in the adaptive immune response.

Answer 2

Innate: keratinized epithelium

stratified squamous epithelium hypodermal areolar connective tissue antigen presenting cells major histocompatibility complexes complement (antibody -dependent pathway )

Innate or non-specific response is the first defense against invaders. Components of this response include physical (e.g. skin . mucosa) and chemical barriers against pathogens and cells such as Natural Killer cells, macrophages, neutrophils, dendritic cells, mast cells, basophils, eosinophils. Innate response reacts immediately.

Adaptive: immunoglobulin plasma cells agglutinin

helper t cells memory t cells cytotoxic t cells cd4+cells

t lymphocytes

Adaptive immune response or specific response is specific to the pathogen presented and mediated by lymphocytes, B and T cells. Adaptive immune response creates immunological memory after the first, initial l response to a specific pathogen which leads to enhanced response.
