Genes – growth and healing is controlled by protein metabolism which is controlled by genes. Mitosis – keeps cells at a healthy ratio and allows new cells to replace ones that can no longer function Cell Differentiation and specialisation– without this there would be no specialized cells to maintain health e.g. lymphocyte production is increased during

morphology of the lymphatic system. Also‚ compare B and T lymphocytes and their roles in immunity. The lymphatic system is responsible for helping the human body fight against diseases and illnesses. This system consists of ducts‚ organs and nodes and transports fluid called lymph. The system contains cells called lymphocytes. Lymphocytes protect the body from antigens. The ducts of the lymphatic system are the home for B-cells and T-cells‚ these ducts also provide transportations for fats‚ proteins

The activation and inhibition of Natural Killer cells is dependent on the balance between stimulation of activating and inhibitory receptors. If the stimulation of activating receptors is more prominent than NK cells will be activated‚ likewise if inhibitory receptors stimulation is dominant than NK cells activity will be suppressed. For the immune system to work the first and foremost requirement is that it should be able to determine whether a cell is infected or not and then it can defend the body

The innate immune system is referred to as the first line in host defense against invading pathogens and preserve host integrity [1]. Of them the innate immune cells have sensors such as macrophages and dendritic cells (DCs) detect molecular components of foreign microorgan¬isms known as pathogen-associated molecule patterns (PAMPs) through PRRs. Its highly developed ability to recognize microbial patterns and host derived danger signals relies on so-called PRRs‚ especially on the TLRs‚ RLRs and
