What occurs when the sympathetic nervous system is stimulated?
Uterine activity
Cardiac output
Pancreatic activity
Gastrointestinal activity
The Correct Answer is B
When the sympathetic nervous system is stimulated, it activates the "fight or flight" response, which prepares the body for physical activity or stressful situations. This response includes several physiological changes, such as:
Increased heart rate and cardiac output: The sympathetic nervous system releases adrenaline and noradrenaline, which increase heart rate and cardiac output to provide more oxygen and nutrients to the muscles.
Decreased uterine activity: The sympathetic nervous system inhibits uterine contractions to prevent
premature labor.
Decreased pancreatic activity: The sympathetic nervous system inhibits insulin secretion and promotes glucagon secretion to increase blood glucose levels.
Decreased gastrointestinal activity: The sympathetic nervous system inhibits digestive functions to divert blood flow to the muscles.

DNA is a double-stranded macromolecule made up of nucleotides that carry genetic information. The sequence of nucleotides in DNA determines the genetic code, which controls the development and function of living organisms. Chromosomes are structures made up of DNA and proteins that carry genes. Nucleotides are the building blocks of DNA and RNA. RNA, on the other hand, is a single-stranded macromolecule that plays a key role in protein synthesis by carrying genetic information from DNA to ribosomes.
