THE HUMAN BODY A LOOK INTO THE HUMAN ANATOMY AND IT’S SYSTEMS Our Amazing Body • Human body is like a machine, in that each part of the body has it’s own job. • These parts work together to keep the body alive, much like the parts of an automobile work to make it run. • There are different systems that make up the human body, let’s explore! SYSTEMS OF THE BODY • The body is made up of several different systems of organs. Each of these systems has it’s own job, that work together to keep the body functioning. They are: Skeletal System, Digestive, Urinary, Respiratory, Circulatory, Nervous and the Reproductive system. SKELETAL SYSTEM • Consists of 206 bones and hundreds of muscles, which helps the body move. • Skeleton has 2 main parts, the axial skeleton, and the appendicular skeleton. THE DIGESTIVE SYSTEM • Prepares food for the cells • Starts with the mouth. Teeth and saliva break food down. • Food travels to the stomach where cells absorb nutrients. THE RESPIRATORY SYSTEM • Includes, nose, larynx, trachea and lungs. • System brings air into the body and removes the carbon dioxide through breathing. • Muscles contract to enlarge the chest. THE URINARY SYSTEM • Involves the Kidneys and urethra. • Removes waste products from the body, which can be poisonous if they are not removed. CIRCULATORY SYSTEM • Carries blood to the body. • The heart, arteries, veins, and capillaries make up the system. • Veins carry blood to the heart. • Arteries carry blood away from THE NERVOUS SYSTEM • Regulates the activities of all the other systems. • It has 5 major regions, the spinal cord, cerebrum, cerebellum, pons, and medulla oblongata. THE REPRODUCTIVE SYSTEM(FEMALE) • The female system produces egg cells. • When an egg is fertilized it stays in the uterus where it develops into a baby. THE REPRODUCTIVE SYSTEM(MALE) • Consists of the testes that produce sperm. • When sperm unites with the egg of the female, fertilization occurs.
