Thephysiological principles in health and social care are to provide a holisticoverview of the human body, structure and functioning as appropriation for healthcareprofessionals. This essay will seek to identify all the ten anatomical featuresof the biological systems; thus a brief explanation of seven anatomical featuresand its functions including a detailed explanation of three biological systems(the gastrointestinal system, the respiratory system and cardiovascular system).Moreover, this essay will also explore the environmental and physical factorsthat hinder the functional performance of the body, and the impact it has on caredelivered to service users in health and social care settings. 1.1 Thehuman body has ten biological systems that carry out specific functions, whichare beneficial for our everyday living. The anatomical features of the humanbiological systems are as follows: · Theimmune system: It defends the body against pathogenic micro-organisms andgerms that are exposed to the human body everyday. The body’s defensivemechanism is achieved through a series of steps called the immune responsewhich attacks micro-organisms and substances likely to invade the body’s systemto cause illnesses.
The immune system is also composed of specialised cells, varioustissues, organs and proteins that work together to protect the body. One of themain cells involved in the body’s defensive activity is the white blood cells,also known as leukocytes. These are produced in many parts of the body. The organsand tissues involved in the immune system are called lymphoid organs which are;spleen, bone marrow, thymus, appendix, lymph nodes, tonsils and the Peyer’spatches found throughout the small intestinal duct. Primarily, leukocytes comein two types; phagocytes and lymphocytes. The phagocytic cells chew harmfulmicro-organisms whilst the lymphatic cells allow the body recognise previousinfectious micro-organism and help the body to destroy them.
Lymphocytes alsoconsists of two types of cells; B- cells and T-cells. B-cells produce antibodiesto attack foreign antigens that causes harm to the body. T-cells, however, hastwo main functions; to recognise and destroy malignant cells, and to orchestratean immune response which play a vital role in immunity.
