What is responsible for delivering oxygen and removing carbon dioxide from the body?
The circulatory system
The respiratory system
Mitochondria
The blood
When you breathe in, you inhale _________ and exhale __________.
Air/ Carbon Dioxide
Carbon Dioxide/ Air
Oxygen/ Air
Oxygen/ Carbon Dioxide
Which of the following is carried by red blood cells in our body?
Air
Oxygen and waste
Oxygen
Oxygen and Carbon Dioxide
The heart had four chambers. Identify the correct path of blood flow when blood renters the heart from the body.
Left ventricle, left atrium, right atrium, left ventricle
Right atrium, right ventricle, left atrium, left ventricle
Right atrium, right ventricle, left ventricle, left atrium
Left atrium, left ventricle, right ventricle, right atrium
What is the purpose of the valves located between the chambers of the heart?
To allow for one way blood flow in the heart and prevent back flow of blood.
To create the thumping noise when the heart is beating.
To help push the blood into different chambers.
To help infuse oxygen into the blood to be carried to the cells in the body.
Often images will show red and blue vessels attached to the heart. What does this depict?
Cool blood returning to the heart and warm blood being sent out to the rest of the body.
The difference between veins and arteries.
The blue vessels shows the flow of deoxygenated blood and the red vessels shows the flow of oxygenated blood.
The blue vessels shows the flow of oxygenated blood and the red vessels shows the flow of deoxygenated blood.
What role do capillaries play in the circulatory system?
They deliver oxygen to cells.
They are the site of exchange for nutrients into cells and connect blood from arteries and veins.
Are tiny vessels that provide blood flow to small parts of the body, such as fingers.
Are the bridge between veins and arteries.
Which system works closely with the circulatory system?
Digestive system
Skeletal system
Nervous system
Respiratory system
Which is the correct definition of the Circulatory system?
Provides shape and structure for the body.
The system that circulates blood and oxygen through the body, consisting of the heart, blood vessels, and blood.
The system fights disease so the body stays healthy.
Brings oxygen into the body and removes carbon dioxide from the lungs.
Where do arteries carry blood?
Towards the heart from the tissues of the body.
To the brain.
Away from the heart and to the tissues of the body.
To the stomach.
The heart is made up of what kind of muscle?
Smooth muscle
Red muscle
Skeletal muscle
Cardiac muscle
Adaptations of the circulatory system include...
Heart location for protection
Capillaries are thin
Arteries have thick walls
All are adaptations
When we inhale the diaphragm...
Gets bigger
Contracts
Expands
Relaxes
When we exhale from the lungs the pressure inside the lungs ______________ and the volume _______________.
Increases/ Decreases
Decreases/ Increases
Decreases/ Decreases
Increases/ Increases
The air sacs that are covered with capillaries are where gas exchange takes place in
Bronchii
Lungs
Cells
Alveoli
What is the function of the diaphragm?
It attaches to the lungs to help in breathing by relaxing and contracting.
This is where gas exchange happens.
Air passes through the diaphragm on the way to the lungs.
It is under the lungs and keeps them from falling down to your stomach.
When carbon dioxide leaves the body, which pathway does it travel?
Bronchii, Alveoli, Pharynx, Larynx, Mouth/Nose
Alveoli, Bronchioles, Eosophagus, Mouth/Nose
Alveoli, Bronchii, Lungs, Pharynx, Mouth/Nose
Alveoli, Bronchii, Larynx, Pharynx, Mouth/Nose
When we breathe in oxygen is....
Moved into our blood by process of osmosis in our alveoli. This is where gas exchange occurs.
Moved into our blood by process of diffusion in our bronchioles. This is where gas exchange occurs.
Moved into our blood by process of osmosis in our bronchioles. This is where gas exchange occurs.
Moved into our blood by process of diffusion in our alveoli. This is where gas exchange occurs.
What is the main organ in the respiratory system?
Heart
Brain
Lungs
Alveoli
Smoking can cause problems in the structure and function of lungs. Identify the correct issue that applies.
Increased lung capacity and reduced oxygen exchange.
Decreased lung capacity and reduced oxygen exchange.
Increased lung capacity and increased oxygen exchange.
Decreased lung capacity and increased oxygen exchange.
The main purpose of the ____________ system is to break food particles into pieces that can be used.
Circulatory
Digestive
Respiratory
Excretory
The chemical process of food breaking down in the stomach occurs via which mechanism?
Hydrochloric acid in the stomach facilitates digestion by breaking down the chemical bonds of foods to smaller particles.
The churning of the stomach to help mix food together to make it easier to digest.
By neutralising harmful pathogens on food to ensure we don't get sick when eating.
By increasing the pH of the stomach to help break down food.
The mechanical process of breaking down food begins where in the body?
In the stomach, where churning actions help mix and break down foods.
In the mouth where enzymes in the saliva begin to break down the bonds holding food together.
In the mouth where chewing motions help break food down into smaller pieces, which helps with digestion.
In the oesophagus where muscles contract to push the food down into the stomach.
Villi are located in the ______________. Their function is to ________________.
Stomach/ releases acids into the stomach.
Intestines/ Help remove waste products from digestion.
Lungs/ Help increase the absorption of oxygen in the lungs.
Intestines/ Increase the surface area for the absorption of nutrients.
Which structure connects the bottom of your throat to your stomach?
Trachea
Windpipe
Oesophagus
Food tube
What are the main parts of the digestive system?
Stomach, small and large intestine.
Mouth, stomach, oesophagus, large and small intestine.
Stomach, lungs, trachea, rectum.
Large and small intestine, trachea, stomach, mouth.
What is the long folded tube inside the body attached to the stomach where nutrients in the food are absorbed?
Large intestine
Oesophagus
Rectum
Small intestine
What is the tube after the small intestine where water is absorbed?
Small intestine
Large intestine
Oesophagus
Rectum
What is the large organ of the digestive system that makes chemicals (bile) to help the body break down fats and rid itself of harmful substances.
Large intestine
Stomach
Liver
Gall bladder
Which structure prevents food from entering the windpipe?
Tongue
Epiglottis
Uvula
Oesophagus
