2. Imagine that you are in a building and the fire alarm goes off. All of the doors around you lock shut, and you smell smoke.
andrew-mc [135]

The main problem that your central nervous system will try to solve is how to get out of this place.

<h3>B. What is the somatic nervous system probably doing?</h3>

It is releasing stimuli so that the pupil dilates and the blood goes to the muscles, to give greater physical vigor.

<h3>ç. Which part of the autonomic nervous system is likely to be active and what is it doing?</h3>

The autonomic nervous system is a part of the nervous system that functions independently of will and consists of neurons that conduct impulses from the central nervous system (brain and/or spinal cord) to the glands, smooth muscle and heart muscle.

<h3>What are the physiological responses of adrenaline binding in the sympathetic autonomic system?</h3>

Adrenaline increases the overall activity of the heart, increasing both the heart rate and the force of contraction. The heart has β1 receptors in both contractile and specialized myocardium. When turning on, a series of cardiac effects can happen.

With this information, we can conclude that the main problem that your central nervous system will try to solve is how to get out of this place.

the protein hemoglobin carries oxygen from the lungs to the tissues. this is an example of protein's role in
xxTIMURxx [149]

Red blood cells contain a protein called hemoglobin. An illustration of red blood cells showing the hemoglobin protein. This protein serves as a transporter of oxygen from the lungs to tissues.

<h3>What are proteins?</h3>

The term "protein" refers to a macro- and large-scale biomolecule that has one or more lengthy chains of amino acid residues.  An amino acid chain makes up the basic building block of proteins.

When oxygen binds to the heme portion of the hemoglobin molecule in red blood cells during physiological respiration, oxyhemoglobin is created. This procedure takes place in the pulmonary capillaries close to the lung's alveoli.

Thus, red blood cells contain a protein called hemoglobin. An illustration of red blood cells showing the hemoglobin protein. This protein serves as a transporter of oxygen from the lungs to tissues.
