Answer:
After a good meal, Jane is relaxing comfortably as her food digests, suggesting her <u>parasympathetic</u> nervous system is in control. When she is frightened by a loud noise, Jane's digestion is inhibited and her heartbeat accelerates, suggesting her<u> sympathetic </u>nervous system is in control.
Explanation:
Parasympathetic nervous system and the sympathetic nervous system are two of the 3 domains of the autonomic nervous system.
During the resting and the relaxing stage,<u> parasympathetic system</u> (also called as rest or digest system) is activated which is associated with the conservation of the energy by :
1) Slowing the heart rate
2) Increasing the intestinal activity ( the reason why Jane is relaxing comfortably as her food digests )
3) Relaxation of the sphincter muscles of the GIT.
While during the fight , flight or fright stage , the <u>sympathetic nervous system</u> is activated which is associated with the body alertness by :
1) Increasing the heart rate
2) Inhibition of secretion of GIT enzymes ( the reason why digestion of JANE is inhibited )
3) Relaxation of the walls and the contraction of the sphincters of the GIT smooth muscle.
Answer:
The function of the circulatory system necessary for the respiratory system to complete the exchanges of gases in the body is red blood cells carrying oxygen away from the lungs (option D)
Explanation:
The respiratory and circulatory systems are related because the supply of oxygen (O₂) to the entire body depends on them, in addition to allowing the expulsion of carbon dioxide (CO₂).
The function of the circulatory system that allows gas exchange in the body and contributes to respiratory function are the red blood cells, which carrying O₂ away from the lungs.
<u>Red blood cells or erythrocytes</u> contain a molecule, hemoglobin, which is responsible for transporting O₂ to the body and removing CO₂ from the tissues to be carried to the lungs for expulsion.
The other options are not correct because:
<em> A and B. White blood cells are not in charge of transporting respiratory gases.</em>
<em> A and C. The exchange of gases does not occur directly to the atmosphere.</em>
When a cell is "at rest" it is in a state called the resting potential. In this state, neurons are more negatively charged ions inside the cell than outside the cell.
Answer:
It has been suggested that women should eat 1200 calories daily while men can eat 1500 calories as the minimum in a day. To maintain weight, women can have 1600-2400 calories daily while men 2000 to 3000 calories a day.
Because when people are educated, they are aware of the social values and the events happening around.
