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:
Explanation:
Blood vessels in the liver that carry deoxygenated blood are known as hepatic veins. More CO₂ and fewer O₂ are delivered to the liver through the hepatic veins, in which the blood is filtered and purified. The pancreas, colon, small intestine, and stomach all have blood in them. It is made up of deoxygenated blood that is devoid of nutrients.
The hepatic venule is a confluence of veins that transport digested nutrients from the intestine to the liver. In terms of volume, it contains less oxygen than hepatic arteries. Between the liver and the gut(i.e the intestine) lies a hepatic venule. It comprises deoxygenated blood including some nutrients.
In summary:
Hepatic veins Hepatic venule
Devoid of nutrients Contains some nutrients
More CO₂ More O₂
Transport blood to the liver Transport blood to inferior vena-cava
