| Question | Answer |
|---|---|
| The steps involed in inhalation and exhalation | Inhale- the digram moves down,the ribe cage moves up an outward.The air flows into mouth and trachea. Exhale- The lungs moves upwardand mucles become relax. Volume in chest decrease and out of lungs. |
| The differance between total lung capacity,vital capacity,and residual volume. | Total Lung Capcity- is the total of Vital and Residual.Vital Capacity- how much air a person can inhale. Residual Volume is how much air is left over after a deep exhale. |
| The process of cellular respiration,the raw materials and products.And explain how body eliminates the waste products. | Cellular Respiration purpose is when glucose combines with oxygen toproduce energy, carbon dioxide, and water. Raw materials are glucose and oxygen. Waste products arecarbon dioxide,water,and energy. Water is elimated by urnation and perspiration. |
| Define the word calorie and explain how you measured the relative calorie valueofsunflower seeds and marshmallow. | A calorie is a unit of heat energy.It is required to raise the temperature of 1 gram of water 1 degree celsius. |
| Explain what blood pressure is and list factors that can influence it. | Blood Pressure is he force exerted by blood vessels walls.Factors- race,heredity, diet,stress, and obesity. |
| Describe the differences between artiers,veins,and cappillaries. | Arteries are vessels that carry blood away from the heart. Rich in oxygen Veins carry blood to the heart. High in CO2 Cappilaries are the smallest vessels. Gas and nutrients exchange |
| Five factors that can effect a persons heart rate. Tell whether it raises or lowers and why. | scared - raise - adrenaline sleeping - lower - doesnt require much work running - raise - work effort caffeine - raise - sugar/stimulant alchohol - lower - depressant |
| List the four main components of blood and their function | plasma - liguid platelets - aid in clotting red blood cells - transport oxygen white blood cells - fight infection & diseases, called warriors |
| The function of valves in the circulatory system and where they are likely to be found | They are a stucture in the heart and some veins that prevent blood from flowing backwards. Found in heart and veins |
| Explain why heart can be called double pump | The right side pumps blood through the lungs and the left side pumps blood through entire body. |
| Name two most important things blood carries to the body cells and the waste gas that blood carries away | Blood carries oxygen and nutrients. Carries away Carbon Dioxide CO2 |
| Tell path of blood through heart, body, lungs | Circulatory System - heart, lungs, heart, body, heart, lungs |
| Describe how bromthymol blue is used as an indicator for carbon dioxide in solution | If it turns from blue to light green to yellow it is positive. |
| How does the Respitory and Circulatory Systems adjusts to meet the demands of the body under different conditions. | As activity increases the heart pumps faster to deliver oxygen and the faster you breathe the heart works faster. |
| Explain how the digestive,respiratory and circulratory system helpone another do to their jobs. | Nutrients from the digestive flows into the blood and carries to the cells.THat uses energy.Oxygen for cellular respiration by the resp system.Circ moves nutrients and oxygen to cells and carries away CO2 to the lungs. Then the heart pumps blood around th |
| Tell about the model of breathing. Lists strengths and limitations. | Strengths - It shows 2 lungs, the windpipe, the bronchia and the change of pressure. Limitations - does not show ribcage and the body is more like a sponge. |
| Tell about model of circulatory system. Lists strengthsand limitations. | Strengths - valves prevent backflow, shows sound, and double pump in closed circulatory system. Limitations - upside down, but the artia is not and there are no vessels. |
| Define epiglottis | a flap that closesand opens, it covers the windpipe to make sure food does not go down it. |
| The primary goal for respiration. | The goal is to produce oxygen and energy for the bodys cells. |
| Know what these scientist are famous for Karl Landstener- Jonas Stalk- Albert Sibin- William Harvey- | Karl- who discover the 4main blood types Jonas- invented a polio vacine Albert-invented a oral polio vacine William-figure out humans have a closed circulatory system. |
