=__** Human Systems **__=

1) There are more than 5 systems in our body. 2) They are called Muscular System,Digestive System,Skeletal System,Respiratory System 3) Muscular system consists of collection of over 600 moving muscles.The main function of the muscular system is to enable the body to move. 4)The digestive system breaks down food into simple forms. 5) The digestive system consists of the mouth,gulllet,stomach,small intestine,large intestine,rectum and anus. 6) The human systems are very important as they help our body function. 7)The Respiratory System consists of the mouth,windpipe and the lungs. 8)The Skeletal System gives our bodies our shape. 9)The Skeletal System works with our Muscular System to help our body move. 10) The Skeletal System protects our body. 11) The Muscular System enables our body to move. 12) The Respiratory System enables the exchange of gases from the surroundings. 13) The Circulatory System carries food, water and oxygen to all parts of the body and carries waste materials and carbon dioxide away from the body. 14)In Respiratory System, the lungs have tiny holes called air sacs. 15)A baby has more bones than the adults. 16)When we exhale, our diaphragm moves upwards. When we inhale, our diaphragm moves downwards. 17)Our skeletal system consists of the skull (cranium), rib cage, hips (pelvis), shoulder blade (scapula), finger bones (phalanges), etc. 18)We take in air rich in oxygen and poor in carbon dioxide while we give out air poor in oxygen and rich in carbon dioxide. 19) Our Respiratory system is made of Nose, Windpipe, Lungs and Air sacs. 20) The circulatory system is made up of the heart, blood vessels and the blood. 21)The Circulatory system transport materials around the body. 22)All the cells in our body require oxygen we get through breathing the air. 23)In the circulatory system, our arteries are thick walled while the veins are thin walled. Arteries transport blood away __from__ the heart. They carry o__xygenated__ blood except in the case of the Pulmonary Artery (to lungs). Veins transport blood __towards__ the heart. They carry d__e-oxygenated__ blood except in the case of the Pulmonary Vein (from lungs). The capillaries are arteries and veins. 25) If the organ systems do not work together as a team, the body will not be able to carry out life processes. 26) The stomach in the digestive system can stretch to hold 3.5 pints of food. 27)The respiratory, circulatory and digestive systems is needed to get oxygen to all parts of our body. 28) There are 4 chambers in a heart. The 4 chambers are the left atrium, the right atrium, the left venticle and the right venticle. 29) There is also a urinary system in our body that controls the bladder. 30)The arteries carry air rich in oxygen while the veins carry air which is not rich in oxygen 31)There are 10 systems in our body,working together to help us carry out life processes. 32)When we breathe through the respiratory system, we inhale oxygen. When we let the breath out, again through the respiratory system, it comes out in the form of carbon dioxide. 33)The circulatory system contains blood which is made out of billions of billions of red blood cell that contain food, oxygen and other wastes. 34)There are other system beside the five we have learnt, such as the nervoys system. 35) The nervous system is a complex network of nerves and cells that carry messages to and from the brain and spinal cord to various parts of the body. 36) The small intestine absorbs most of the nutrients found within our food. 37)The skeletal system supports the body and gives it its shape.
