circulatory system - -carries oxygen and nutrients to cells in the body and carries carbon dioxide away from cells to lungs -heart, arteries, veins, digestive system - -mouth, stomach, intestines -breaks down large food molecules into tiny food molecules that can move through the intestine walls, into the blood, and then into each cell, muscular system - -involuntary and voluntary muscles -moves the body’s parts; both external (arms, legs) and internal (lungs, stomach, heart), nervous system - -nerves, brain, spinal cord, sensory organs -controls the actions of the body, store memories, and process information from the outside world, respiratory system - -mouth, nose, lungs -brings oxygen into the body and sends carbon dioxide out of the body (exchanges), sensory organs - -eyes, ears, nose, tongue, skin, What is the difference between arteries and veins? - Arteries-Away from the heart VeINs-Back INto heart, What provides a link between nerves in the body and the brain? - the spinal cord, voluntary muscles - when a person wants them to move (like lifting an arm or smiling), involuntary muscles - move things a person does not normally control ex. muscles that move food through your intestine, heart, WHERE is food broken into tiny particles so it can be picked up by the blood and delivered to the cells? - small intestine, What happens to your heart rate and breathing rate when you exercise? - -your heart beats faster so that more blood gets out to your body -your breathing rate increases because as your muscles work harder, your body uses more oxygen and produces more carbon dioxide, Digestive System - The digestive system works with the nervous system when the nervous system tells the digestive system when to be active and when to rest., Nervous System - The nervous system works with the muscular system when it tells the muscles how and where to move., Circulatory System - The circulatory system works with the nervous system when the brain controls how fast the heart beats depending on activity., Respiratory System - The respiratory system works with the circulatory system when the red blood dells travel to the lungs to pick up oxygen and carry the oxygen to all body parts., Muscular System - The muscular system works with the digestive system when we eat, the involuntary muscles help move the food through the system as it gets broken down into smaller pieces.,
