Physiological Principles for Health and Social Care Essay

The circulatory establishment is the bes apotheosis governing dead consistence. It is do up of a host of organs that transport farm animal passim the body. The affection pumps the blood and the arteries and veins transport it. oxygen-rich blood leaves the left side of the heart and enters the biggest artery, called the aorta. The aorta separatees into little arteries, which then branch into even smaller vessels that travel all over the body. When blood enters the smallest blood vessels, which be calledcapillaries, and are found in body wind, it gives nutrients and oxygen to the cells and takes in vitamin C dioxide, water, and waste. The blood, which no longer contains oxygen and nutrients, then goes endure to the heart through veins. Veins guide waste products away from cells and bring blood back to the heart , which pumps it to the lungs to pick up oxygen and eliminate waste carbon dioxide.Digestive SystemThe compendive outline of rules is do up of organs that b reak follow out fodder into protein, vitamins, minerals, carbohydrates, and fats, which the body needs for energy, growth, and repair. After intellectual nourishment is chewed and swallowed, it goes overthrow the esophagus and enters the stomach, where it is further broken down by ruling stomach acids. From the stomach the food travels into the small intestine. This is where your food is broken down into nutrients that can enter the bloodstream through tiny hair-like projections. The excess food that the body doesnt need or cant digest is turned into waste and is eliminated from the body.Endocrine SystemThe endocrine constitution is made up of a group of glands that produce the bodys long-distance call messengers, or hormones. Hormones are chemicals that control body functions, such as metabolism, growth, and intimate development. The glands, which include the pituitary gland, thyroid gland, parathyroid glands, adrenal glands, thymus gland, pineal body, pancreas, ovaries, an d testes, release hormones directly into the bloodstream, which transports the hormones to organs and tissues throughout the body.Immune SystemThe resistive dust is our bodys defense system against infections and diseases. Organs, tissues, cells, and cell products work up to casther to respond to dangerous organisms (like viruses or bacteria) and substances that may enter the body from the environment. There are three types of solvent systems in the immune system the anatomic response, the inflammatory response, and the immune response. The anatomic response physically prevents arduous substances from entering your body. Examples of the anatomic system include the mucous membranes and the skin. If substances do get by, the inflammatory response goes on attack. The inflammatory system works by excreting the invaders from your body. Sneezing, runny noses, and fever are examples of the inflammatory system at work. Sometimes, even though you dont feel well while its happening, you r body is fighting illness. When the inflammatory response fails, the immune response goes to work. This is the underlying part of the immune system and is made up of uncontaminating blood cells, which fight infection by gobbling up antigens. About a quarter of light blood cells, called the lymphocytes, migrate to the lymph nodes and produce antibodies, which fight disease.lymphatic SystemThe lymphatic system is also a defense system for the body. It filters out organisms that cause disease, produces white blood cells, and generates disease-fighting antibodies. It also distributes fluids and nutrients in the body and drains excess fluids and protein so that tissues do not swell. The lymphatic system is made up of a ne cardinalrk of vessels that assist circulate body fluids. These vessels carry excess fluid away from the spaces between tissues and organs and return it to the bloodstream. sizeable SystemThe muscular system is made up of tissues that work with the haggard system t o control movement of the body. Some muscleslike the ones in your armor and legsare voluntary, meaning that you decide when to move them. Other muscles, like the ones in your stomach, heart, intestines and other organs, are involuntary. This means that they are controlled automatically by the aflutter system and hormonesyou often dont even realize theyre at work. The body is made up of three types of muscle tissue skeletal, smooth and cardiac. Each of these has the ability to contract and expand, which allows the body to move and function. squandered muscles help the body move.Smooth muscles, which are involuntary, are located inside(a) organs, such as the stomach and intestines. Cardiac muscle is found that in the heart. Its motion is involuntary Nervous SystemThe awkward system is made up of the brain, the spinal cord, and nerves. One of the most important systems in your body, the nervous system is your bodys control system. It sends, receives, and processes nerve impulses t hroughout the body. These nerve impulses tell your muscles and organs what to do and how to respond to the environment. There are three parts of your nervous system that work together the of import nervous system, the peripheral nervous system, and the autonomic nervous system. The central nervous system consists of the brain and spinal cord. It sends out nerve impulses and analyzes information from the ace organs, which tell your brain about things you see, hear, smell, taste and feel. The peripheral nervous system includes the craniospinal nerves that branch off from the brain and the spinal cord. It carries the nerve impulses from the central nervous system to the muscles and glands. The autonomic nervous system regulates involuntary action, such as heart beat and digestion.Reproductive SystemThe reproductive system allows humans to produce children. Sperm from the male fertilizes the females egg, or ovum, in the fallopian tube. The fertilized egg travels from the fallopian tub e to the uterus, where the fetus develops over a point in time of nine months.Respiratory SystemThe respiratory system brings air into the body and accepts carbon dioxide. It includes the nose, trachea, and lungs. When you breathe in, air enters your nose or mouth and goes down a long tube called the trachea. The trachea branches into two bronchial tubes, or primary bronchi, which go to the lungs. The primary bronchi branch off into even smaller bronchial tubes, or bronchioles. The bronchioles end in the alveoli, or air sacs. Oxygen follows this path and passes through the walls of the air sacs and blood vessels and enters the blood stream. At the akin time, carbon dioxide passes into the lungs and is exhaled.Skeletal SystemThe skeletal system is made up of bones, ligaments and tendons. It shapes the body and protects organs. The skeletal system works with the muscular system to help the body move. Marrow, which is soft, fatty tissue that produces red blood cells, many white bloo d cells, and other immune system cells, is found inside bones.urinary SystemThe urinary system eliminates waste from the body, in the form of urine. The kidneys remove waste from the blood. The waste combines with water to form urine. From the kidneys, urine travels down two thin tubes called ureters to the bladder. When the bladder is full, urine is discharged through the urethra.
