STatiana [176]3 years ago

<span>There are three primary systems in the body that act as a buffer, in order to help maintain pH stability. The first is known as the phosphate buffer, which neutralizes excess hydroxide ions as they enter cellular fluid. The second is called the protein buffer, and maintains acidity in the body. The hemoglobin in blood, which binds to acids in the bloodstream, is one such example of this system. The third system is called the carbonic acid bicarbonate buffer, which neutralizes the acids generated by various metabolic processes, such as digestion and respiration.</span>

Be able to compare/contrast humoral immunity with cellular immunity.
aksik [14]

Solution:

The difference between them are:


The humoral system of immunity is also called the antibody-mediated system because of its use of specific immune-system structures called antibodies. The first stage in the humoral pathway of immunity is the ingestion (phagocytosis) of foreign matter by special blood cells called macrophages. The macrophages digest the infectious agent and then display some of its components on their surfaces. Cells called helper-T cells recognize this presentation, activate their immune response, and multiply rapidly. While,


The cell-mediated immune response involves cytotoxic T-cells, or killer-T cells. Body cells that have been infected by foreign matter often present components of that material on their surfaces. Killer-T cells recognize these displays and respond by ingesting or otherwise destroying the infected cell. Killer-T cells are also important in the body's defenses against parasites, fungi, protozoans, and other larger cells that might have found their way into the body. The killer-T cells recognize these large invaders by their foreign proteins and then destroy them.  

This is the required answer.
