| EXCRETORY SYSTEM | This system cleans the blood of waste substances in the form of urine and sweat and eliminates them from the body. |
| WHAT DOES THE CIRCULATORY SYSTEM CONSIST OF? | It consists of the heart, blood vessels and blood. |
| WHAT DOES OUR BLOOD GIVE TO OUR CELLS? | Oxygen and nutrients. |
| WHICH WASTE PRODUCT DOES OUR BLOOD HELP GET RID OF? | Carbon dioxide |
| WHAT DOES THE RESPIRATORY SYSTEM DO? | It helps us breathe in oxygen and breathe out carbon dioxide |
| WHICH MUSCLE, FOUND BELOW THE LUNGS, HELPS US TO BREATHE? | The diaphragm. |
| WHAT IS THE RESPIRATORY SYSTEM MADE UP OF? | It is made up of (nose and mouth) larynx, trachea, bronchi, bronchioles, alveoli, and lungs. |
| WHAT ARE VOCAL CORDS FOR? | They vibrate and make sound. |
| WHICH PART OF THE RESPIRATORY SYSTEM CONTAINS THE VOCAL CORDS? | The larynx. |
| HOW WORKS THE DIAPHRAGM? | It contracts and relaxes to let us breathe in and out. |
| NOSTRILS | Two holes in the nose through which we breathe, smell, and (sometimes) sneeze. |
| WHAT IS THE NASAL CAVITY FOR? | It moistens and filters the air that comes into the body. |
| ALVEOLI | Very small air sacs in the lungs. |
| LUNGS | Spongy organs where gas exchange occurs. |
| THE 3 PHASES IN THE RESPIRATION PROCESS | Inhalation, gas exchange, and exhalation. |
| THE 3 TYPES OF BLOOD VESSELS | Arteries, veins, and capillaries. |
| HOW DOES THE HEART WORK? | It contracts (pushes the blood into the arteries, to the rest of the body) and relaxes (fills with blood coming from the veins) automatically. |
| BLOOD | The red liquid that carries the nutrients and oxygen our body needs. It also transports the waste substances that our body eliminates. |
| HEARTBEAT | The continuous contracting and relaxing of the heart. |
| WHAT IS THE EXCRETORY SYSTEM MADE UP OF? | Kidneys, ureters, the bladder, and urethra. |
| WHICH ORGANS CLEAN WASTE FROM OUR BLOOD? | Kidneys. |
| WHERE DOES URINE COLLECT BEFORE IT LEAVES THE BODY? | In the bladder. |
| WHAT IS URINE MADE UP OF? | The waste combines with water to make urine. |
| HOW DOES URINE LEAVE THE BODY? | Through the urethra. |
| KIDNEYS | Filter waste products from the blood and return the clean blood back to the circulatory system |
| WHAT DOES THE EXCRETORY SYSTEM CONSIST OF? | The urinary system and the sweat glands. |
| WHAT DO SWEAT GLANDS CONSIST OF? | A tube that filters the blood and a pore that opens to the outside. |
| WHAT DO THE SWEAT GLANDS PRODUCE? | SWEAT |
| SWEAT | A mixture of waste substances and water. |
| WHERE DO THE NUTRIENTS THAT OUR BLOOD CARRIES TO OUR CELLS COME FROM? | The food we eat, and the oxygen we breathe. |
