Respiratory & Circulatory System
Description of the circulatory and respiratory system working together. And a short view of the lymphatic system
Lesson 1 Circulatory System - Grade 9
The circulatory system transports blood throughout the body to deliver oxygen and nutrients to cells and remove waste. It includes the heart, which pumps blood through vessels. There are three main types of blood vessels - arteries, which carry blood away from the heart; veins, which carry blood back to the heart; and capillaries, which connect arteries and veins and allow exchange of materials with body cells. The circulatory system moves blood in a double circulation from the heart to the lungs and back, and from the heart to all body tissues before returning to the heart.
Circulatory system
The circulatory system transports blood containing oxygen and nutrients throughout the body using blood vessels and the heart. The circulatory system consists of blood, blood vessels, and the heart. Blood is made of plasma, red blood cells, white blood cells, and platelets. Red blood cells carry oxygen and carbon dioxide, white blood cells protect against infection, and platelets form blood clots to stop bleeding. Arteries carry oxygenated blood from the heart while veins return deoxygenated blood to the heart. Capillaries connect arteries and veins to deliver blood to tissues. The heart is a hollow muscle with four chambers that pumps blood through the circulatory system around 60-100 times per minute, increasing during exercise to meet higher
Circulatory System
The circulatory system transports blood throughout the body using the heart, blood vessels, and blood. The heart pumps blood through arteries, veins, and capillaries, which carry oxygen, nutrients, waste, and carbon dioxide between tissues and organs. The circulatory system includes pulmonary circulation from the heart to the lungs, coronary circulation through the heart tissue itself, and systemic circulation from the heart to the rest of the body except the lungs.
Powerpoint circulatory system
The circulatory system transports blood around the body which contains red blood cells, white blood cells, platelets suspended in plasma. Red blood cells contain hemoglobin and carry oxygen, while white blood cells help fight infection and platelets help with clotting. The heart pumps blood through arteries and veins with a dual circulation system. Blood vessels have valves to prevent backflow. The circulatory and lymphatic systems work together to fight infection, transport nutrients and remove waste throughout the body.
Circulatory system
The circulatory system consists of the heart and blood vessels that maintain continuous blood flow around the body. The heart is a hollow, muscular organ located in the chest behind the sternum. It has four chambers - two upper atria and two lower ventricles. Blood vessels include arteries, which carry blood away from the heart; capillaries, which connect arterioles and venules; and veins, which carry blood back to the heart. There are two circulatory loops - systemic circulation provides oxygenated blood to the body through arteries and deoxygenated blood back to the heart through veins, while pulmonary circulation carries deoxygenated blood from the heart to the lungs and returns oxygenated blood to the heart.
Circulatory system for Class 8
The circulatory system document summarizes the key components of the human circulatory system in 3 parts: blood, blood vessels, and heart. It describes how blood consists of plasma and formed elements like red blood cells, white blood cells, and platelets. It outlines the types of blood vessels - arteries, veins, and capillaries. Finally, it provides details on the structure and function of the heart, including the 4 chambers, valves, heartbeat, and how blood is pumped through pulmonary and systemic circulation.
SCIENCE 9 Respiratory System
The document summarizes the respiratory and circulatory systems. It discusses the major organs involved in breathing including the nose, mouth, pharynx, larynx, trachea, bronchi, bronchioles and lungs. It explains that during inhalation, air is brought into the lungs through the nose and mouth and passes through the pharynx, larynx, trachea and bronchi before reaching the bronchioles and alveoli in the lungs where oxygen passes into the blood and carbon dioxide passes out of the blood. During exhalation, the process is reversed as carbon dioxide is expelled from the lungs.

Respiratory and circulatory systems.pptx
The respiratory system takes oxygen from the air into the lungs and removes carbon dioxide from the body. The circulatory system transports oxygen and nutrients throughout the body and removes carbon dioxide. When breathing in, the diaphragm contracts and lungs expand to take in air through the nose, mouth, throat and windpipe into small air sacs in the lungs called alveoli. When breathing out, the diaphragm and chest relax, pushing carbon dioxide out through the same pathways. The heart pumps oxygen-rich blood to the body and oxygen-poor blood to the lungs through networks of arteries, veins and capillaries to exchange gases and nutrients with tissues.
Cardiopulmonary system overview
The cardiorespiratory system has two main functions: (1) to transport oxygen to tissues and remove waste, and (2) regulate body temperature. It consists of the cardiac system including the heart and blood vessels, and the respiratory system including the respiratory passageways and lungs. Together, these systems work to ensure proper gas exchange between the body and atmosphere by collecting oxygen from the environment and transporting it to tissues via the bloodstream.

The document also provides examples of lesson workflows using apps like Edmodo, Dropbox, Google Drive and Showbie to collect student work.
What Affects Weather Patterns
1) A place's latitude and proximity to oceans or large bodies of water help determine its climate and weather patterns. Locations closer to the equator tend to be warmer, while areas farther from the equator experience more distinct seasons.
2) Climate zones like polar, temperate, and tropical regions exist depending on latitude. Hemispheres also influence seasons, with the northern and southern hemispheres experiencing opposite seasonal changes at the same time.
3) Geography such as mountains and bodies of water further impact local weather. Mountains can create rain shadows - dry areas on their leeward sides. Meanwhile, coastal areas tend to have milder temperatures regulated by the moderating effect of oceans.
Weather Quiz #2
This document contains a 10 question weather quiz about air masses, fronts, and weather patterns. The quiz questions cover topics like how studying weather maps helps scientists, the definition of a front, how temperature is affected during cold and warm fronts, types of weather associated with high and low pressure systems, typical weather conditions during hurricanes, the coldest season in North Carolina, the most common precipitation in North Carolina, identifying fair weather based on descriptions, which front type brings prolonged clouds and precipitation, and predicting weather when a cold air mass interacts with a warm air mass. The answers to the 10 multiple choice questions are provided at the end.
Fronts
Fronts are boundaries where two different air masses meet. A cold front occurs when a cold air mass pushes beneath a warm air mass, often bringing strong storms like thunderstorms or snowstorms and a drop in temperature. A warm front happens as a warm air mass slowly moves over a cold air mass, producing stratus clouds and rain and eventually causing temperatures to rise. Stationary fronts can also form when air masses stop moving against each other, leading to prolonged clouds and precipitation.
Air Masses
An air mass is a large body of air that covers thousands of square kilometers and has consistent temperature and moisture levels throughout. There are four main types of air masses: continental polar (cold and dry), maritime polar (cold and humid), continental tropical (warm and dry), and maritime tropical (warm and humid). Weather maps are used to track the movement of air masses, which can significantly impact weather conditions over wide areas.
Weather Maps
Meteorologists use weather maps to make predictions about how the weather will change. Weather maps show data from weather stations around the world, including temperature, precipitation, as well as features like fronts and areas of high and low pressure. Scientists study weather maps to help predict how the weather is likely to change based on patterns in the current conditions shown on the maps.
Precipitation & Clouds
Certain types of clouds are more likely to produce specific types of precipitation. Tall cumulus clouds can produce heavy rain or snow showers that do not last long, while stratus clouds typically produce long-lasting smaller drops of rain or snow. Clouds with strong vertical development hold a lot of water and often reach heights where freezing occurs, making them more likely to produce hail.
clouds and precipitation
There are 4 main types of precipitation: rain, sleet, snow, and hail. Rain falls in heavy drops that form from melted ice crystals in clouds. Snow falls when ice crystals remain frozen as they fall from cold clouds, joining together to form snowflakes. Sleet is partly frozen rain that forms when raindrops pass through a layer of cold air near the ground. Hail consists of balls or chunks of ice that can form in tall, dense cumulonimbus clouds.
Clouds and Precipitation
There are 4 main types of precipitation: rain, sleet, snow, and hail. Rain falls in heavy drops and forms from melted ice crystals in clouds. Snow falls from clouds as frozen ice crystals that stick together to form snowflakes. Sleet is partly frozen rain that forms when raindrops pass through cold near-ground air. Hail consists of balls or chunks of ice that can form in tall, storm-producing cumulonimbus clouds.
Types of Clouds
There are three main types of clouds: stratus clouds, which are low and blanket-like; cumulus clouds, which are puffy and allow blue sky between them; and cirrus clouds, which are the highest clouds and look wispy. Stratus clouds can bring rain, while cumulus clouds sometimes grow vertically into rain-bearing cumulonimbus clouds. Cirrus clouds form in fair weather but often precede rainy conditions. Fog is also a cloud that forms near the ground.
Weather Pop Quiz
This document contains a pop quiz about weather with 8 multiple choice questions asking about meteorologists, the six elements of weather, instruments used to measure temperature, precipitation, wind speed, air pressure, and how low pressure systems impact weather conditions. The questions are followed by short answers to each question identifying a meteorologist as a weather scientist, listing the six elements of weather, and naming instruments such as a rain gauge, anemometer, and barometer used to measure different weather phenomena.
Weather - What are clouds?
Clouds form when warm air rises into the cooler parts of the atmosphere, causing water vapor to condense into liquid water droplets or ice crystals around particles in the air called condensation nuclei. As more and more water condenses around these particles, it creates clouds made of billions of water droplets or ice crystals that appear different depending on their composition, with water droplet clouds having sharper edges and ice crystal clouds looking fuzzier and whiter.
Weather - Air Pressure
Air pressure is the weight of the atmosphere pressing down at a certain location. It can change as air particles move farther apart or closer together. Weather scientists use a barometer to measure air pressure. There are two types of air pressure - high and low - and changes in air pressure indicate that weather is changing, with low pressure typically bringing rainy or stormy conditions while high pressure usually means fair weather and sun.
Weather - Wind
Wind is moving air that is measured using tools like weather vanes and anemometers. A weather vane spins freely and points in the direction the wind is blowing from, while an anemometer uses cups on arms to spin and measure wind speed by counting spins over time. Wind is produced by differences in air pressure and temperature, with high winds occurring during storms like blizzards, tornadoes, and hurricanes.
Precipitation
This document discusses different types of precipitation including rain, sleet, snow, and hail. It explains that precipitation occurs when water droplets or ice crystals in clouds join together and become heavy enough to fall. The different types of precipitation form through different processes as water condenses around nuclei in the clouds and falls through varying air temperatures. A chart is provided to classify precipitation types as solid or liquid and illustrate how each forms through condensation and the collection of cloud droplets or ice crystals.
Weather - Precipitation
Precipitation is water that falls from the atmosphere in forms like rain, snow, hail, and sleet. A rain gauge is used to measure the amount of precipitation, where rain or melted snow collects in a can or tube with marks on the side indicating quantity. Different forms of precipitation are rain, sleet, snow, and hail, which are examined individually to understand how each forms from the atmosphere.
Weather - Introduction & Temperature
Weather is defined as the condition of the atmosphere at a given time and place. Scientists use tools like thermometers, barometers, rain gauges and anemometers to measure conditions and predict tomorrow's weather. Meteorologists are scientists who study weather and its elements, which include air temperature, pressure, humidity, precipitation, clouds, fog and wind.
Industrial Revolution - Transportation
The document discusses how transportation changed during the Industrial Revolution in the United States. New inventions like steamboats and railroads made transportation of goods and people faster and cheaper. Canals were built to connect waterways, cutting shipping costs. By the 1850s over 9,000 miles of railroads had been laid, connecting cities in the East and allowing raw materials and manufactured goods to be transported easily around the country. These transportation improvements fueled the growth of manufacturing across the United States.
Texas and The Mexican American War
American settlers in Texas rebelled against Mexican rule in 1835 and declared independence in 1836. Texas remained an independent republic for nine years before becoming a U.S. state in 1845. This led the U.S. and Mexico to go to war from 1846 to 1848 over the boundary between Texas and Mexico. Through the Treaty of Guadalupe Hidalgo, Mexico ceded much of the modern Southwest to the U.S., including California, Nevada, Utah, and parts of other states, in exchange for $15 million. This war significantly increased U.S. territory and the number of Mexican citizens living under American rule.

Respiratory and Circulatory Systems
- 2. Respiratory System • Takes in oxygen from the air that you breathe. • Lungs are the main structures in this system.
- 3. Respiratory System • Air enters your body through nose or mouth, moves down your throat & passes through the trachea or windpipe, then to your lungs.
- 4. Respiratory System • Oxygen is taken into your blood and carbon dioxide leaves your blood. • Your diaphragm lies below the lungs. The diaphragm & muscles around it tighten and relax to make you breathe in and out.
- 6. Circulatory System • Carries oxygen, food, & waste throughout the body • Made up of the heart, blood vessels, and blood
- 7. Circulatory System • Heart is the center of this system, it pumps blood through blood vessels called arteries. • Heart is also called the cardiovascular muscle.
- 8. Circulatory System • Blood moves from arteries into capillaries. • In the capillaries oxygen & food move from the blood to the body’s cells • Blood then moves through veins back to the heart.
- 9. Circulatory System • The circulatory system also works with the respiratory and digestive systems.
- 10. Circulatory System • Respiratory system gives oxygen & the circulatory system takes that oxygen to other cells. • Digestive system breaks down food & the circulatory system carries the nutrients to cells in the body.
