I used to think that blood vessels only had minor differences from each other in things like size. Now however, I have realised that it's actually quite interesting how different blood vessels have adapted to have completely different limitations and capabilities.

# data[].attributes.body
1. Different blood vessels have different functions. They have evolved to perform they're specific function and support the circulatory system by being as efficient as possible so you aren't low on oxygen
2. ADD--> For exaple arteries have thick elastic to cope with the high pressures. Veins have valves to stop a backflow of blood. Capillaries are one cell think so only red blood cells can get in
3. I used to think that blood vessels were extremley similiar but now I think that they are quite diverse in terms of properties due to the diverse functions

I used to think that Blood Vessels were one cell thick as this helped with diffusion.

But now I think that only capillaries are one cell thick, and now I know more. For example I know more about the lumen and how it contracts and expands in the artery and veins. I also know more about the capillaries, and how they use diffusion.

I used to think that all blood vessels were the same, the only thing that was different was the direction that the blood was flowing in.

Now I know that the blood vessels have different purposes/jobs that help the body in different ways. Because of this, they are different shapes and they have different thicknesses

I used to think blood vessels had the same kinda shape but know i know blood vessels have different structures as they have different specific functions.

# data[].attributes.body
I used to think that different parts of the body had typed of blood vessels to be able to support the different pressures of the circulatory system. Now I think that the different sizes (capillarys) also allow for blood to reach all parts of the body and properly provide the required oxygen and nutrients

I used to think that the heart was very simple, with only four distinct sections, but now I understand that there is a lot more the heart does, with the different veins and arteries.

# data[].attributes.body
I used to think that the circulatory system consisted of blood vessels which more or less had the same function and structure. But I know I that each blood vessel has its own purpose and a structure which corresponds to its purpose.

In Picture:

I used to think that different parts of the circulatory system had different types of blood vessels in order to be able to support the different blood pressures of the body travelling around, but now I realise that there are more function-related reasons as to why there are different types of blood vessels

# data[].attributes.body
about only their features but now in addition to that I know why they need to have those features and how it is important for the body for these vessels to perform their function that these features allow them to undertake

I used to think that the heart/circulatory system was very simple and that the veins and arteries did more or less the same think, but now I understand it's a lot more complicated and that it does a lot more.

I used to think that the heart structure and functions were very simple and easy to understand, but now I know that there is much more to the heart than just that 'it carriers blood'

# data[].attributes.body
I used to think that structure and function were very simple, but now I think that there is always more detail that can be added.

How does the composition of the blood enable the body to respond to internal and external stimuli

How does the composition of the blood enable the body to respond to internal and external stimuli

# data[].attributes.body
From this lesson, I learnt that the bloods functions are very broad and learned a lot more about the specific terminology to describe the composition and conditions within blood

How your original answer compares to the group’s final answer: At first I was looking at the blood vessels mainly and trying to vaguely figure out how their function linked to stimuli. At the end of the lesson we had looked at deficiencies and that showed me how important the blood is at fighting stimuli.

How your thinking has developed since the start of the lesson: I have been able to make specific link towards the problems that lacking certain parts of blood can have.

My original answer only mentioned the oxygen carried by the red blood cells in the blood, but now I understand the functions of the white blood cells and platelets and how they all respond to external stimuli.

Below is a picture of our groups poster.
My original answer was quite vague  and I only discussed the blood having red blood cells to carry oxygen and that white blood cells and platelets are to help fight infections in the body.
Our final group answer went into more depth for the 3 types of blood cells that we covered. We also had a deeper understanding of how these blood cells helped the body to respond to certain stimuli.

I used to think that the heart was barely related to our lungs and oxygen since I have seen a heart live without a body, but now I think The heart and lungs work together to make sure the body has the oxygen-rich blood.
