Circulatory system is the transport system. It consists of a group of, transport blood throughout the body.

The heart pumps blood and >> << transportation. Oxygen-rich blood comes from the left side of the heart and enters the large arteries is called. Aorta branches of arteries less than that then power an even smaller vessels that travel throughout the body. When blood enters the tiny blood vessels called, and found in the tissues of the body, gives nutrients and oxygen to cells and takes carbon dioxide, water and waste. Blood that does not contain oxygen and nutrients, and then returns to the heart through veins. Vienna carrying waste from the cells and bring blood back to the heart, which pumps it into the lungs to pick up oxygen and eliminate carbon dioxide waste. The digestive system consists of organs that break down food into protein, vitamins, minerals, carbohydrates, and fats that the body needs energy, growth and recovery. After meals chew and swallow, it goes down the esophagus and enters the stomach, where they defeated the powerful stomach acid. From the stomach the food travels into the small intestine. Here, food is broken down into nutrients that can enter the bloodstream through tiny hair like projections. Excess food, the body does not need or can not digest becomes waste and is excreted from the body. Endocrine system consists of a group of glands that produce the body of long-distance messengers, or hormones. are chemicals that control body functions such as metabolism, growth and sexual development. Including pituitary, thyroid, parathyroid glands, adrenal glands, thymus, pineal gland, pancreas, ovaries and testes, release hormones directly into the bloodstream, which carries hormones to organs and tissues throughout the body. The immune system is our body's defense against infections and diseases. Organs, tissues, cells and cell products that work together to respond to dangerous organisms (like viruses or bacteria) and substances that may enter the body from the environment. There are three types
lasix to pass drug test of responses in the immune system: anatomical response to an inflammatory response and immune response. physically prevent the threat substances in your body. Examples of anatomic system include the mucous membranes and skin. If the matter can not do, inflammatory reaction is to attack. release of the invaders from your body. Sneezing, runny nose, fever inflammatory examples of the work. Sometimes, even if you do not feel good, but it happens, the body fights disease. When the inflammatory process can not, >> << go to work. This central part of the immune system and consists of white blood cells that fight infection gobbling up. About a quarter of white blood cells called lymphocytes, migrate to the lymph nodes and produce antibodies that fight disease. The lymphatic system is a system of protection of the body. It filters out organisms that cause disease, produces white blood cells, and provides for disease control 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 consists of a network of blood vessels that help circulate body fluids. These vessels carry excess fluid from the space between the tissues and organs and return it to the bloodstream. The muscular system consists of tissues that work with the muscular system of body movement. Some muscleslike those in the hand and legsare voluntary, which means that you decide when to move them. Other muscles, like those in the stomach, heart, intestines and other organs, are involuntary. This means that they are managed automatically by the nervous system and hormonesyou often do not even realize that they are at work. The body consists of three types of muscle tissue: skeletal, smooth and cardiac. Each of them has the ability to contract and expand, allowing the body to move and function .. help the body move. That are involuntary, are located inside organs such as stomach and intestine. can be found only in heart. His involuntary movements >> << nervous system consists of the brain, spinal cord and nerves. One of the most important systems in the body, nervous system control system of your body. It sends, receives and processes nerve impulses throughout 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 the nervous system that work together: central nervous system, peripheral nervous system and autonomic nervous system. consists of the brain and spinal cord. It sends nerve impulses to and analysis of information from sensory organs that tell your brain about what you see, hear, smell, taste and feeling. includes Kraniospinalni nerves that branch off from the brain and spinal cord. It carries nerve impulses from CNS to muscles and glands. regulates involuntary actions such as heartbeat and digestion. Reproductive system allows people to do in light of children. Sperm from the male fertilizes the eggs the female, or egg in the fallopian tube. Fertilized egg travels the fallopian tube into the uterus where the fetus develops for nine months. From the respiratory system causes air in the body and removes carbon dioxide. It includes the nose, trachea and lungs. When you inhale, air enters the nose or mouth and down a long tube called the trachea. Trachea branches into two bronchi, or primary bronchi, which go into the lungs. The main bronchi branch of an even smaller bronchi and bronchioles. Bronchiole ends in the alveoli, or air bags. Oxygen should be this way and through the wall air sacs and blood vessels and enters the bloodstream. At the same time, carbon dioxide enters the lungs and exhaled. Skeletal system consists of bones, ligaments and tendons. It forms the body and protects organs. Skeletal system works with the muscular system to help the body move. Who is the soft, fatty tissue that produces red blood cells, many leukocytes and other cells of the immune system inside the bone. Urinary system removes toxins from the body as urine. The kidneys eliminate waste from the blood. Waste in conjunction with water to form urine. In the kidneys, urine goes down two thin tubes called ureters into the bladder. When the bladder is full, urine is excreted through the urethra. Fact Monster / Information Please Database, 2007 Pearson Education, Inc All rights reserved. .
