Respiratory System Circulatory System The main function of the respiratory system is to provide the body oxygen which all cells need to provide energy The circulatory system then transfers the oxygen to all the cells in the body via red blood cells It also gets nutrients from the blood and brings it to the lungs Excretory System Circulatory System The main function of the excretory system is to get rid of nitrogenous waste which are toxic to the body Kidneys filter blood brought to them by the circulatory system Also the circulatory system gives oxygen and nutrients to the excretory system We get rid of nitrogenous waste through urine and sweat This helps us maintain homeostasis Nervous System Circulatory System The main function of the nervous system is to carry messages from the neuron to the brain There are three types of neurons motor neurons sensory neurons and interneurons The sensory neuron carry messages to the brain and the motor neurons gets the message from the brain and the interneurons are in the brain and spinal cord They compare by the interneurons are send the message to the brain telling the heart to beat Also the circulatory system brings oxygen and nutrients to the nervous system Digestive System Circulatory System The main function of the Digestive System is to take away nutrients from the food you eat The digestive system and circulatory systems work together because the digestive system gets the nutrients from the food we eat and it goes into the blood so our cells have the nutrients to produce energy The digestive system also gets oxygen from the circulatory system

Nervous System Skeletal System The main function of the nervous system is so that you can move and feel things The skeletal system is your bones and without your bones you would not be able to walk or stand Also your cranium protects and supports your brain and if that wasn t protected we couldn t move or live either Requirement 6 The digestive system takes the nutrients from the food and the respiratory system gets oxygen from and the air Both of those combined to create energy But the mitochondria turns those into energy but also makes co2 gas and nitrogenous waste Our respiratory system gets rid of the co2 gas by us breathing While the excretory system gets rid of the nitrogenous waste by us using the bathroom The circulatory system helps in this process by moving everything around such as the blood oxygen and nutrients
