Regulates heart activity via the vagus nerve?
Parasympathetic nervous system
Inhibition of parasympathetic nervous system activity causes the salivary glands to become?
hypoactive
Which activity is effective for increasing oxygen production?
Replanting trees is effective for increasing oxygen production.
Which human activity has had the greatest impact on increasing mercury levels?
burning coal for energy
Decreasing heart rate is under the control of what nervous division?
Parasympathetic
Which of these is stimulated by parasympathetic nerves?
Parasympathetic nerves stimulate resting and digesting. Therefore, stomach activity is stimulated by parasympathetic nerves.
Does increased parasympathetic activity cause blood pressure to increase?
no
What is the name for the specific part of the heart which sets the rate at which the heart will beat?
The pacemaker of the heart is known as the sinoatrial (SA) node. It sets the rate at which the heart will beat without any autonomic stimulation, that is, no sympathetic or parasympathetic activity. Increases in sympathetic activity will increase the heart rate while increases in parasympathetic activity decrease heart rate. The pacemaker of the heart is known as the sinoatrial (SA) node. It sets the rate at which the heart will beat without any autonomic stimulation, that is, no sympathetic or parasympathetic activity.

What is the term for the background rate of sympathetic and parasympathetic activity?
Autonomic tone
Regulates heart activity via the vagus nerve?
Parasympathetic nervous system
What is innervate?
Innervated by both the sympathetic and parasympathetic nervous system. This allows for both branches of autonomic NS (sympathetic and parasympathetic) to precisely control an organ's activity.
What is dual innervation?
Innervated by both the sympathetic and parasympathetic nervous system. This allows for both branches of autonomic NS (sympathetic and parasympathetic) to precisely control an organ's activity.
Inhibition of parasympathetic nervous system activity causes the salivary glands to become?
hypoactive
Two types of controlling systems that assist in regulating heart activity?
Parasympathetic and sympathetic
What happens to pressoreceptor activity when bLood pressure in the carotids fail?
Pressoreceptor activity decreases because it is part of the heart and is a parasympathetic response.
Which activity is effective for increasing oxygen production?
Replanting trees is effective for increasing oxygen production.
How does increasing activity can improve fitness levels?
