6 White Heart Dissection!

Today in 6 White, we were learning all about the heart. As part of this, we went to the science pod to dissect a heart and look at the different parts and their purpose.

Dissecting the heart…
Having a closer look…

Back in the classroom, we labelled diagrams and discussed how blood is pumped around the body and gets replenished with oxygen by the lungs. 

Can you answer the following questions, 6 White?

  • Why did one side of the heart need more muscle?
  • What was the middle part of the heart called? What did it do?
  • What was your favourite part of dissecting the heart? Anything you didn’t enjoy?
  • What are the four chambers called?
  • Which side of the heart carries de-oxygenated blood? Which side carries oxygenated blood?
  • Why does the diagram appear to be backwards?
  • Describe the process of blood being pumped through the heart – use the proper terminology. Start from the Superior Vena Cava.

  1. 1.) The reason for this difference in muscle size is because the left ventricle needs to pump blood to the whole body, compared to the right ventricle which only pumps blood to the lungs.
    2.) A wall of muscle blocks the de-oxygenated blood from mixing in with the oxygenated blood.
    3.) My favourite part was when I got to hold the heart.
    4.) The 4 chambers are right atrium,left atrium,right ventricle and the left ventricle.
    5.) De-oxygenated blood is carried on the left side and oxygenated blood is carried on the left side of the heart.

  2. 1)The left side of the heart needs more muscle.
    2)A wall of muscle called the septum blocks the de-oxygenated blood from mixing in with the oxygenated blood.
    3)I really enjoyed holding the heart and seeing it being cut open.
    4)the 4 chambers are called: right atrium , right ventricle , left atrium , left ventricle.
    5)De-oxygenated blood is on the on the right side of the heart and oxygenated blood is in the left side of the heart.
    6)The diagram appears to be backwards because when we stand straight and someone is in front of us their right is our left and their left is our right.
    7)The superior vena cava pumps the de-oxygenated blood to the right atrium which pumps the blood to the right ventricle. It then pumps the blood to the pulmonary veins which leads it to the lungs to get oxygen. It then pumps the blood to the left atrium and then it pumps the oxygenated blood to the left ventricle which pumps the blood up the aorta and to the rest of the body.

  3. 1)It needed more muscles because It needs to pump blood around the body.
    2)The middle part was called the septum and stoped the oxeyganeted blood mixing with the de-oxygenated blood.
    3)I like all of It because it was interesting.
    4)The four chambers are right ventricle and right atrium and left atrium and left ventricle

  4. 1)The reason for this difference in muscle size is because the left ventricle needs to pump blood to the whole body, compared to the right ventricle which only pumps blood to the lungs
    2) The middle part of the heart is called theAtrial Septum. It separates the atriums and ventricles.
    3) My favourite part of the heart dissection was when we cut open the four chambers of the heart and looked at how they were connected. Also, I enjoyed the part when we got to feel how heavy the heart is!!!
    4) The four chambers of the heart are called the right atrium, right ventricle, left atrium and left ventricle.
    5) The right side of the body carries the de-oxygenated blood whereas, the left side of the body carries oxygenated blood.
    6)The reason why the diagram appears to be backward is because when we look at the heart, we look at it from an angle where the person is facing us. So when we look at it, the peron’s right seems to be our left and the vice versa.
    7) Starting at the Superior Vena Cava, de-oxygenated blood comes into the right atrium. The blood then transfers into the right ventricle where it flows into the lungs through the pulmonary artery. The lungs make th blood oxygenated and send it through the pulmonary vein and into the left atrium. There it goes into the right ventricle and into the rest of the body.

  5. 1)the side that needed more muscle was the side on the right because the left pumps blood a further distance.
    2)the middle part of the heart is called the myocardium and it is responsible for pumping blood.
    3)my favourite part was when we were cutting the heart because I liked what I saw inside of the heart.
    4)the four chambers are called the right atrium,right ventricle,left atrium and left ventricle.
    5)the right side that carries deoxygenated blood and the left side carries oxygenated blood.
    6)the diagram appears backwards because if u put the diagram on your chest then it wouldn’t be backwards.

    • Remember to proof-read your answers Sariyyah (capital letters, spaces etc)!
      Questions 3, 4 and 5 have some good responses. Have another go at the other questions.

  6. 1) One side of the heart needs more muscle because the side that sends blood to the lungs is close by so it doesn’t need that much strength, whereas the side that sends blood to the rest of the body is going further away so it needs more strength.
    2) The middle part of the heart is called the myocardium. It is responsible for pumping the heart.
    3)I didn’t enjoy any of it , it was quite disgusting to me to be honest.
    4) The right atrium, The right ventricle, The left atrium and the left ventricle.
    5) The right side Carries de – oxygenated blood. The left side carries the oxygenated blood.

  7. Because it had a longer way to travel so it needed more strength.
    My faviroute part was when we got to hold the heart in our hands.
    The chambers are left atrium right atrium and left vertical and right ventical.

  8. One side of the heart needed more muscle because it needs the strongest beat to pump the blood around the whole body.My favourite part about dissecting the heart was being able to see and understand the 4 main chambers of the heart.The part I didn’t enjoy was seeing a blood clot. Right atrium and left atrium and right ventricle and left ventricle. The diagram is shown back wards because when you put your back to it that is the way around it goes. The side of the heart that carries the oxygenated blood is the left atrium and the left ventricle. The side that carries de oxygenated blood the the right atrium and right ventricale. First it goes through the superior vena Carva into the right atrium. Then the de oxygenated blood goes into the right ventricle. Then it will go through the pulmanery artery into the lungs. Then it will go through the left pulmanery vein back to the heart. Because it has been to the lungs the blood will become oxygenated blood. Then once it is back at the heart it will start its cycle again.

  9. 1. So the blood can go through.
    2. The brain was the middle part of the head.
    3.the bit where we sqeeezed it and it felt weird.
    4. The four are atrients 2 and 2 ventricles.
    5. The right atrium. And oxygenated gets carried by the left atrium.
    6.because it looks like it’s on the right but from the real way it’s from the left and also the heart is made like that.
    7. So first it goes through the superior vena cava then goes into the atrium then gets oxygenated and goes to the rest of the body out of the aorta.

  10. It needed muscle to pump through the brain and the rest of the body.
    It was called the septum and it was a thick layer imbetween the four chambers right atrium left atrium also left ventricle right ventricle.
    I love felling and looking what inside a real heart.
    The right side carries de -oxgynated blood.
    Because this is as if if your facing a doctor so it looks wrong way round but it isn’t.
    At the start the superior vena Carla goes through down to the right ventricle where it wants to get oxgynated blood. So it travels through the left puma ray atery towards the lungs .Next it goes back through the veins to the heart at the heart it restores the blood.After that it through the atery to get to the rest of the body.Finally it comes back to the aorta.

  11. One side of the heart needed more muscle because it was the main part that pumped more blood.
    My favourite part of dissecting the heart was at the end when we got to hold it.I enjoyed all of it and I didn’t dislike any of it.
    The four chambers are called the left atrium ,the right atrium ,left ventricle and the right ventricle.
    The left side of the heart carries deoxygenated blood and the right side carries oxygenated blood.
    The diagram appears to be backwards because it is laid out as if you where looking at someone’s heart or someone was looking at yours.
    Deoxygenated blood comes back from the rest of the body and goes into the right Atrium.it then flows into the left ventricle the left ventricle pumps the blood into the left pulmonary artery and sends the blood to the lungs.The oxygenated blood comes back through the right pulmonary vein and goes into the left Atrium.The cycle repeats when the left Atrium send the oxygenated blood through the Aorta to the rest of the body
