3.   How does the skeletal system allow movement? (answer)  Joints Skeletal 100

4.   Name 3 types of joints and where they are located in the body. (answer)  Pivot – neck  Hinge – elbow, knee  Ball-and-socket – shoulder, hip  Gliding – wrist, ankle Skeletal 200

5.   What is the importance of water in the skeletal system? Explain. (answer)  Lubricant – reduces friction at joints and keeps them moving smoothly Skeletal 300

6.   What are the 4 main functions of the skeletal system? (answer)  Protects internal organs  Makes red blood cells  Allows movement  Stores minerals Skeletal 400

7.   Why does the skeletal system depend on the muscular system? (answer)  The skeleton is built to move, but doesn’t have the capability to move on its own. The muscles attach to bones to make them move. Skeletal 500

8.   What is the primary function of the muscular system? (answer)  movement Muscular 100

9.   What are the 2 types of muscle action? Explain. (answer)  Voluntary – move under your control  Involuntary – move without you thinking Muscular 200

10.   What are the 3 types of muscle? Where in the body can each be found? (answer)  Cardiac – only in the heart  Smooth – lines the walls of digestive tract  Skeletal – attached to bones Muscular 300

11.   Skeletal muscles must work in pairs to move bones. What are these pairs? Explain. (answer)  Flexor – contracts to bend a body part  Extensor – contracts to straighten a body part Muscular 400

12.   Why would some muscles fail to work properly if a bone is broken? (answer)  Skeletal muscle is attached to bone, and if the bone is broken the flexors and extensors wouldn’t be able to pull on the bone to move the joint. Muscular 500

13.   What is another name for the cardiovascular system? (answer)  Circulatory system Cardiovascular 100

14.   What are the 5 parts that make up this system? Explain each of their functions. (answer)  Heart – pumps blood  Blood – delivers oxygen and nutrients  Artery – takes blood away from the heart  Capillary – allows an exchange of materials from blood cells to other body cells  Vein – takes blood back to the heart Cardiovascular 200

15.   What is the difference between systemic and pulmonary circulation? (answer)  Systemic – circulation of blood from the heart to the body and back to the heart  Pulmonary – circulation of blood from the heart to the lungs and back to the heart Cardiovascular 300

16.   Why is water important in the cardiovascular system? (answer)  Temperature Regulator – absorbs heat to help keep body temperature constant Cardiovascular 400

17.   Why are other systems dependent on the cardiovascular system? (respiratory, digestive, urinary) (answer)  The blood will transport (pick up and deliver) oxygen, nutrients and waste materials around the body Cardiovascular 500

18.   What is the primary function of the respiratory system? (answer)  To bring in oxygen and get rid of carbon dioxide Respiratory 100

19.   What are the structures that make up the respiratory system? (answer)  Nose, pharynx, larynx, trachea, bronchi, lungs, bronchioles, and alveoli. Respiratory 200

20.   Explain the importance of the alveoli. (answer)  Alveoli filter oxygen from the air and pass it into the blood stream through capillaries. At the same time, carbon dioxide is passed into the alveoli from the blood to be removed from the body. Respiratory 300

21.   What is the role of water in cellular respiration? Explain. (answer)  Metabolite – water helps the cells perform chemical reactions such as cellular respiration Respiratory 400

22.   What is the difference between breathing and respiration? (answer)  Breathing is inhaling and exhaling air.  Respiration is getting and using oxygen. Respiratory 500

23.   What are the structures that make up the digestive system? (answer)  Mouth, pharynx, esophagus, stomach, pancreas, small intestine, liver, gallbladder, and large intestine. Digestive 100

24.   What are the two types of digestion? Explain. (answer)  Mechanical digestion – physically breaking, ripping, smashing (etc.) into smaller pieces  Chemical digestion – using substances to breakdown into smaller molecules Digestive 200

25.   What is the role of water in regards to digestion? (answer)  Solvent – water helps to dissolve nutrients so the body can use them Digestive 300

26.   What are the organs that assist with digestion, but are not part of the digestive tract? Explain their functions. (answer)  Liver – stores nutrients, makes bile, breaks down toxins  Gallbladder – stores bile and squeezes it into the small intestine to break down fat.  Pancreas – protects the small intestine from stomach acid in chyme, by neutralizing the acid Digestive 400

27.   Why is the small intestine so long? Explain. (answer)  Villi are fingerlike projections in the small intestine that absorb nutrients from food. It is long so that it can get as many nutrients as possible from the food. Digestive 500

28.   What are the structures that make up this system? (answer)  Kidneys, ureters, urinary bladder, urethra Urinary 100

29.   What is the tube in which urine leaves the body? (answer)  Urethra Urinary 200

30.   Where does urine get stored before it can be expelled from the body? (answer)  Urinary bladder Urinary 300

31.   What is the primary function of the urinary system? (answer)  To remove waste from the blood that was made in the body. Urinary 400

32.   What are nephrons? Explain how they function. (answer)  Nephrons are microscopic filters in the kidneys. They filter the waste and water out of the blood which makes urine. Most of the water and the nutrients are returned to the blood and the blood is recirculated. The urine leaves the kidneys in tubes called ureters. Urinary 500
