Yes. The vagus nerve is a parasympathetic nerve that is almost always stimulating the healthy heart to have a heart rate less than the inherent rate of the SA node.
The sympathetic innervation on the heart is minimal and only important during exercise.
Sympathetic neurons cause pacemaker cells to generate action potentials more frequently, and thus increase heart rate. In contrast, parasympathetic neurons have the opposite effect; they cause a decrease in the frequency of action potentials generated by peacemaker cells, and thus decrease heart rate. The heart simultaneously receives both sympathetic and parasympathetic signals in a "push-pull" manner. Increases in one are accompanied by decreases in the other.
SNS increases heart rate, contraction strength, etc, PSNS inhibits (i.e) slow down heart rate, decrease blood pressure, contraction strength, etc.
The affect that the parasympathetic nervous system has is that it decreases the heart. The result in terms of the cardiac output is that it decreases cardiac output.
The sympathetic and the parasympathetic nervous systems work together to maintain in a balanced state of homeostasis. The sympathetic takes care of the arousal and the parasympathetic handles the calming.
Yes. Together they work for betterment of the body.
cells are specialized for a specific function, they work together to make tissues. Those tissues work together to form organs. Those organs work together to form organ systems
the respiratory and cardiovascular system work together/
Groups of cells that work together are called tissues.
The sympathetic and the parasympathetic nervous systems work together to maintain in a balanced state of homeostasis. The sympathetic takes care of the arousal and the parasympathetic handles the calming.

em work together
They antagonize the action of each other. That means one system works against other system. Together they perform the desired function. Together they work better.
Body systems work together to keep the body healthy and the body systems are interdependent (they rely on each other).
That is the organismal level. Many organisms have several organ systems.
the respiratory and cardiovascular system work together/
they work together by filtering at the same time
Most of the systems are interconnected so they work together, like respiratory system works with the circulatory system.
