I learnt that not only the blood vessels carry oxygen,food and water but also waste materials which will be discarded from our body

# data[].attributes.body
I want to know why the blood needs to return back to the heart.

# data[].attributes.body
I know that the circulatory system is made up of three organs, the heart
(which pumps blood), blood( has many types and blood vessels.

# data[].attributes.body
I learned that exercising temporarily increases the heart rate, but lowers in the long term, and is good for heart health.

# data[].attributes.body
I want to know how the blood is pumped from the heart.

# data[].attributes.body
I know that we cannot survive without the circulatory system because then dissolved food, oxygen and water will not be able to go to al parts of the body and waste materials such as carbon dioxide will not be able to exit the body.

# data[].attributes.body
I learnt that there are 3 blood vessels, known as artery, capillary, vein.

# data[].attributes.body
I want to know how many blood vessels are there in the circulatory system .

# data[].attributes.body
I know that the circulatory system mainly consists of the heart,blood and blood.

# data[].attributes.body
I want to know where blood comes from

# data[].attributes.body
I learnt that red blood cells are made from the bone marrow in the hip and thigh bones

# data[].attributes.body
I want to know where the blood is made from in the body.

# data[].attributes.body
I know that the blood transports substances such as oxygen, carbon dioxide, hormones, water, heat and waste materials to and from the body.
I also know that the blood vessels consists of the arteries, capillaries and veins.

# data[].attributes.body
I know that the respiratory system consists of the nose, windpipe and lungs.
Our respiratory,digestive and circulatory system. If one does not function properly, we will not survive.

# data[].attributes.body
I have learnt why having enough blood for the body keeps us healthy as it gives us oxygen and digested food. I also learnt that when we cut ourselves with a rusty metal, the rust would go into our blood and might give us infection.

# data[].attributes.body
I want to know why different people have different blood types and why it matters.

# data[].attributes.body
I know that the circulatory system consists of these three main parts: heart, blood, and blood vessels. The function of the heart is to pump blood for the body. The function of the blood vessels is to transport the blood that is pumped by the heart to all parts of the body, remove any waste materials and transport digested food and oxygen to all parts of the body. Blood contains oxygen and digested food. If one of this organs fail, our body will not function properly.

# data[].attributes.body
I have learnt that how fast the heart can pump blood.

# data[].attributes.body
I want to know if there is other ways to pump blood to yourself.

# data[].attributes.body
I know that the system works with other different systems to transport, nutrients , water and food to other parts of the body

# data[].attributes.body
I have learnt that the inhaled oxygen will be passed into the blood and the carbon dioxide as well as other gases inhaled will be removed as we breathe out. The digested food and water from our digestive system will be absorbed into our blood as well. The blood with our digested food, water and oxygen then goes to our heart where it will be pumped through our blood vessels to all parts of our body.

# data[].attributes.body
I want to know if exercising is the only way your heart rate can go up.

# data[].attributes.body
I know that the respiratory system consists of the nose, windpipe and lungs and the circulatory system consists of the heart, blood and blood vessels.

# data[].attributes.body
I learnt that there are separate blood vessels to carry oxygenated blood cells and deoxygenated blood cells.

# data[].attributes.body
I want to know how the blood cells give oxygen to the cells of the body.

# data[].attributes.body
I know that the circulatory system consists of the heart, blood vessels, and blood. The heart pumps the blood to all parts of the body

# data[].attributes.body
I want to know if different kinds of animals that different heart rates.

# data[].attributes.body
I learnt that the heart rate can change depending on what you are doing.

# data[].attributes.body
I want to know how does the heart actually can pump blood.

# data[].attributes.body
I learnt that the circulatory helps us pump blood all around our body

# data[].attributes.body
I learnt that:
1. The heart is a muscular organ that circulates the blood around the whole body. It works together with the respiratory and digestive systems to supply oxygen and digested food to the cells.
2. The blood absorbs oxygen from the lungs  small intestine .
3. The heart contracts to pump blood that is rich in oxygen and digested food to all parts of the body through the blood vessels.

# data[].attributes.body
I want to know if different living things have different heart rates.

# data[].attributes.body
Circulatory:
I know that the human circulatory system consist of the heart, blood vessels, and blood. It transports digested food (nutrients) and oxygen to all parts of the body and transports waste products, such as carbon dioxide, away from the cells to be removed from the lungs.

# data[].attributes.body
I have learnt that the Respiratory System, Digestive System and Circulatory system need to work together.

# data[].attributes.body
I want to know why the average rates beats at 60-100 per minute for a healthy adult.

# data[].attributes.body
I know that the heart rate changes with age

# data[].attributes.body
I know that the circulatory system consists of the heart, blood vessels and blood.

# data[].attributes.body
I want to know how many beats per minute an average child's heart can beat.

# data[].attributes.body
I have learned that the heart is separated into the left and right side. I also know that the left side contains oxygen-rich blood and the right side contains oxygen-poor blood.
