Answer:
The circulatory system has evolved over time from simple diffusion through cells, in the early evolution of animals, to a complex network of blood vessels that reach all parts of the human body. Made of specialized and unique cardiac muscle, it pumps blood throughout the body and to the heart itself.
Claps shut at birth. Evolutionary changes in the vertebrate heart are tied to change from single to double-circuit heart, with increased separation of oxygenated and deoxygenated blood, allowing more efficient respiration and circulation to fuel high activity and increased oxygen demands associated with endothermy.
it becomes how much of the plant is composed of non-cellular material, like wood. Trees are usually between 60 and 80% water, bushier, less woody plants and water plants can be up to 95% water. Finally, as pointed out, humans are animals, so go with the animal stats for humans. 68% water about average.
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.
