For the answer to the question above, I believe that the answer to your question is that the heart rate will decrease if there's an extreme vagus nerve stimulation <span>The vagus nerve is part of the parasympathetic nervous system. The sympathetic nervous system is the "fight or flight" part of the autonomic nervous system, whereas the parasympathetic is the "feed or breed" part. The sympathetic side acts to speed things up; it increases heart rate, the blood pressure, also the respiratory rate, it dilates pupils, shunts blood away from the GI tract, and so on...
The parasympathetic the opposite in which acts to slow things down; it lowers down the heart rate or decrease blood pressure, it increases salivation, increase blood flow to the GI tract, and so on. The two systems are always balancing each other. The confusing part is that when you INCREASE the activity of the parasympathetic nervous system you DECREASE the activity of the heart; so increased vagal tone will slow the heart rate, decreases the contractility, and lowers blood pressure. When the heart is excitable and has certain types of arrhythmia, increasing the vagal stimulation can slow the heart down enough to allow the normal pacemaker functions to take over again also called as converting.</span>
Answer:
They are neither plants nor animals. They are organisms that are classified under the Kingdom Protista.
Explanation:
Answer:
Carbon monoxide consists of one oxygen and one carbon atom that’s why carbon monoxide is not an atom.
Explanation:
The model describes how cellular membranes i.e. lipid bilayers are organized. Despite the fluidity, lipid bilayers can form certain domains with different characterisrics and compositions. The cell can use different mixtures of lipids to create a 'mosaic' or 'patchwork' of domains.
An example of such domains are so called 'lipid rafts' which are aggregates of certain lipids (mostly cholesterol and sphingomyelins). In these rafts the lateral diffusion of membrane-bound proteins is strongly reduced, thereby forming stable complexes to facilitate, for example, signal-processing and transduction.
Note that a lot about how or why a cell creates these domains is still unknown.
Answer:
Angiotensin II and ADH (in high doses) ___Increases_________ peripheral resistance and blood pressure; and angiotensin II, aldosterone, and ADH ___Decreases_________ urine output to help maintain blood volume and blood pressure. ANP stimulates__volume receptors_____ , which decreases _peripheral resistance__________ and increases _in porasium serum_______ , which decreases blood ____volume________ . The net effect is a decrease in blood ____Pressure________
Explanation:
Angiotensin II is a powerful vasoconstrictor, greatly increasing blood pressure. It also stimulates the release of ADH and aldosterone, a hormone produced by the adrenal cortex. Aldosterone increases the reabsorption of sodium into the blood by the kidneys.
Atrial natriuretic peptide (ANP) is released in response to increased stretch in atria as a consequence of high blood volume and high blood pressure. The effect of ANP is to decrease both peripheral resistance and blood volume with a resultant decrease in blood pressure to within normal homeostatic limits.
