The five body systems The five body systems help us to move,eat,breathe… In this document I teach you the five body systems and the functions, parts or types of the systems. The Locomotor system The locomotor system is a system that is made up of bones, muscles and joins.The locomotor system have a lot of joins, muscles and bones.Every of this parts have different types.Types of joins, types of muscles and types of bones.The types of bones are flat such as the sternum, short such as the vertebrae and long such as femur.The types of muscles are smooth are involuntary, skeletal are voluntary and cardiac is involuntary muscle like a heart.Types of joints are fixed such as those in skull, semi-flexible such as vertebrae and flexible such as our hands.The functions are movements, protects the organs, hold by upright.Brain sends electrical signals to the locomotor system to move thanks to motor neurons. The Digestive system The digestive system is very important because it helps our body get enough nutrients from food for example to be able to play in the park and especially to keep us healthy and strong.The ingestion contains mouth, tongue, teeth and salivary glands.The digestion only contains the stomach.The absorption contains the liver, small intestine, large intestine and pancreas.The defecation contains large intestine, rectum and anus.The propulsion only contains the esophagus.The body cuts food into tiny pieces to be absorbed by the cells, all this happens when you begin to chew the food, the teeth do the function of crushing and reduce it to small portions, these portions when swallowed go down through the esophagus and reach the stomach, from there they pass to the small intestine, when the pieces of food run through it, they are fragmenting more and more, thanks to the digestive juices manufactured by our body, finally most of the food goes through another duct where it is fed to the cells. The Respiratory system The respiratory system is in charge of breathing.Breathing take the oxygen from the air and eliminate co2.Respiratory system is a group of organs.Nose and mouth take the oxygen go down through the trachea then go to the bronchi and enters in lungs then go to the bronchiole then in the alveoli exchange of gasses 02 and nutrients produce energy. The Circulatory system The circulatory system is the responsible of supply 02 and nutrients to the body in heart beat to move the blood.The organs of the circulatory system are heart, arteries, blood, veins and capillary.The organs of the pulmonary circulation are blood in the heart, lungs and heart.The organs of the systemic circulation are blood in the heart, rest of the body and heart. The Urinary system The urinary system is the system which produces the urine and sweat glands which produce sweat.The organs of the urinary system are kidneys, ureters, bladder and urethra, the renal arteries carry blood to the kidneys, the kidneys remove waste products and any water, the renal veins take the clean blood away from the kidneys, the ureters take the urine to the bladders and when the bladder is full we know that we need to urinate because the bladder send a messenger to the brain, when we urinate, urine leaves the bladder and passes through the urethra and out of the body.
