What is the function of the chemoreceptors in the carotid arteries and aorta?

I will illistrate my answers with an example:
When an individual exercises, the concentration of CO2 in the blood increases, this lowers the pH, making it more acidic. Chemoreceptors in the carotid arteries and aorta detect this decrease in pH. Nerve impulses are sent to the centre of the Medulla Oblongata that increases heart rate. Nerve impulses are then sent via the sympathetic nervous system to the sinoatrial node, this increases the heart rate. Therefore this increases the blood flow to the lungs, CO2 can therefore be removed from the blood by the alveoli in the lungs.

The branch of the aorta that divides into the right subclavian and right common carotid arteries?
Brachiocephalic Artery
What artery supplies blood to the head and neck?
The left and right common carotid arteries branch off the arch of the aorta. They travel up through the neck and at the level of C4 divide into external and internal carotid arteries. The internal travels more deeply and ultimately the blood it carries supplies areas of the brain, the external is more superficial and is largely responsible for supplying areas of the neck and face.
What comes off the aorta?
Three arteries come off the Aortic Arch (from left to right) 1. Brachiocephalic Artery 2. Left Common Carotid Artery 3. Left Subclavian Artery. Then After the Aorta arches it then descends behind the heart and turns into the Descending Aorta which is then classified as either the Thoracic Descending Aorta or the Abdominal Descending Aorta.
What is the largest vessel that is attached to the heart and what does it do?
The largest vessel attached to the heart is the Aorta, and it is responsible for delivering blood to the body. It is categorized in 2 groups, the Ascending Aorta and the Descending Aorta. The Ascending aorta includes the Carotid Arteries, which deliver blood to the brain, and the Subclavian Arteries, which brings blood to the arms. The Descending Aorta is located in the thoracic cavity with the rest of the heart and Aorta and is the part of the Aorta that curves down toward the bottom of the body and branches off into other arteries which supply the bottom portion of the body with blood.
What is main artery?
The aorta. This leaves the heart (left ventricle) loops over (aortic arch) and becomes the descending aorta. Their are other arteries that branch off along the way, carotid, brachial, etc. then the aorta splits into the femoral arteries.
Where are the Chemoreceptors located for the detection of low oxygen in the body?
carotid arteries and the aorta
Chemoreceptors that regulate breathing are located in the?
In the AORTA and in the CAROTID ARTERY
Where are baroreceptors located?
There are baroreceptors located in the aorta and at the carotid bifurcation. These function to modulate the cardiac output and maintain normal blood pressure and an adequate perfusion pressure to the brain.
First blood vessels to branch from aorta?
That would be the Carotid arteries.
Which receptor is likely to detect changes in carbon dioxide and oxygen concentration in the blood?
The receptors that are likely to detect changes in carbon dioxide and oxygen concentration in the blood are chemoreceptors located in the aorta and carotid arteries. These chemoreceptors detect changes in the pH of the blood and send signals to the brain to regulate breathing heart rate and other bodily functions. The receptors are sensitive to the following: Carbon dioxide concentration Oxygen concentration pH of the bloodThe chemoreceptors are located in the walls of the aorta and carotid arteries and are sensitive to the changes in carbon dioxide and oxygen concentrations. When the concentrations of these two gases change the chemoreceptors send signals to the brain which then responds with appropriate adjustments in breathing rate and heart rate.
What are the four branches of the aorta?
Right and left commmon carotid arteries and aight and left subclavian arteries.
The branch of the aorta that divides into the right subclavian and right common carotid arteries?
Brachiocephalic Artery
What is the main blood vessel that goes to the brain?
Carotid arteries supply blood to brain . Blood is supplied to the entire brain by 2 pairs of arteries: the internal carotid arteries and vertebral arteries. The right and left vertebral arteries come together at the base of the brain to form a single basilar artery. The basilar artery joins the blood supply of the internal carotid arteries in a ring at the base of the brain. This ring of arteries is called the circle of Willis. The circle of Willis provides a safety mechanism...if one of the arteries gets blocked, the "circle" will still provide the brain with blood.
Baroreceptors that function in the regulation of blood pressure are located in?
Baroreceptors regulate the blood pressure of all vertebrae and are located in the blood vessels. It is a type of mechanoreceptor which is excited when a blood vessel is stretched.
What artery supplies blood to the head and neck?
The left and right common carotid arteries branch off the arch of the aorta. They travel up through the neck and at the level of C4 divide into external and internal carotid arteries. The internal travels more deeply and ultimately the blood it carries supplies areas of the brain, the external is more superficial and is largely responsible for supplying areas of the neck and face.
What are the first branches of the aorta called?
the coronary arteries which pump blood to the heart. Then comes the brachiocephalic trunk which turns into the right subclavicular artery and the right carotid and then the left carotid and left subclavicular come.
What is function of the pericardial sac?
The pericardial sac (or pericardium) is a dual-walled sac that contains the heart and the roots of the great vessels (vena cavae, pulmonary arteries, pulmonary veins, aorta, brachiocephalic arteries and veins, carotid artery and subclavian artery).
