brain rather than the heart. Is knowledge based on science more valid than
knowledge based on intuition? Support your claim.

I personally believe that knowledge is based on science instead of intuition. Emotions are highly investigated by biologists and psychologists. Emotions are considered feelings. The brain and the heart have their own separate functions in the body. The heart's job is to circulate blood throughout the body and up to the brain. We are able to hear heart beats due to its function of pumping blood to other organs in our bodies. This means that emotions may not come from the heart. The brain on the other hand is a part of the nervous system. The brain functions to regulate the majority of our body and mind's functions. This includes functions such as breathing, heart rate, sleeping, eating etc. The brain needs to go through several processes in order for a behaviour to occur. The brain is divided into different parts, each having a different function that produces a different behaviour. Emotion, and feeling emotions is considered a behaviour. One brain region that controls this is the amygdala. 
Emotions are controlled by human experience, and it does also have something to do with intuition and our senses. When we experience different things everyday, we visually see such things happen, which then can evoke a certain type of emotion within us. Vision from the eyes travel straight to the nervous system and the brain will receive neurons to communicate the message around the brain. The brain interprets this message and then send it to the five senses, through the neurons. The senses are sent through the nervous system and then to the body. The brain is able to communicate through neurons, to figure out which brain area is responsible for a specific activity. Things like hormones, neurotransmitters and pheromones also contribute to the communication between brain cells in order to develop a behaviour. ]]> 2019-02-25 14:02:53 UTC https://padlet.com/msyumul/5c0i7mktrgf4/wish/334844154 venlavallas https://padlet.com/msyumul/5c0i7mktrgf4/wish/334852595 (b) Understanding of the structure of the cardiovascular system has allowed the
development of heart surgery.

I agree with this statement. It is clear that Galen was primitively the one who explored around dissection. His work is based on observation and dissection, but some of his work was wrong as he only dissected animals, not humans. He thought that blood flowed from one side of the heart to the other. Harvey was able to prove him wrong as he obtained a better understanding of blood flow in the cardiovascular system, and he was able to map out the entire human body as well. Knowing what the human body consists of, and how blood circulates around the body, has an advantage in being able to perform heart surgery to further figure out what causes certain diseases. Heart surgery also allows surgeons to fully see how the heart works and pumps blood, and allows them to get a fuller picture of the structure of the heart. Knowing how blood flows and how the cardiovascular system works in general has allowed surgeons as well as other regular people to account for how to regulate and control bleeding in emergency situations, and when in surgery. ]]> 2019-02-25 14:16:20 UTC https://padlet.com/msyumul/5c0i7mktrgf4/wish/334852595
