Enzymes are proteins that control the speed of chemical reactions in your body. Without enzymes, these reactions would take place too slowly to keep you alive. Some enzymes, like the ones in your gut, break down large molecules into smaller ones.
As blood pressure increases and the hearts is working harder the most vulnerable arteries area are those <u>Located near the heart, because they are absorbing the most shock.</u>
<u></u>
Explanation:
When the heart pumps blood, the highest pressure is felt close to the heart. This is why the aorta, the artery that carries blood away from the heart is made up of thick walls to withstand this pressure, otherwise, these vessels would rupture. Away from the heart, this pressure lessens, and the blood vessels are not so thick-walled.

Hello. This question is incomplete. You forgot to attach the image that completes the question.
The image is attached below:
Answer:
A- Sensory Neuron
B- Spinal cord
C- Effector neuron
D - Brain
Explanation:
- Sensory neuron: Its main function is to allow the reception of stimuli that are transformed into nervous impulses and electrical signals, capable of realizing sensations, such as a peliscão, for example. These impulses are transmitted to the spinal cord.
- Spinal cord: The main function is to support the body in an upright and vertical position. It also has the function of transmitting electrical signals and nerve impulses between some parts of the body and the brain.
- Effector neuron: Its main function is to receive muscle stimuli capable of creating muscle contractions. These neurons are located in the spinal cord.
- Brain: the processing center receives all the stimuli sent by the bone marrow. Its main function, in this case, is to produce bodily responses to the stimuli it has received, producing muscle movement.
