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.
What do powerful telescopes detect around nearby stars?
They detect waves coming off of the closest stars
Can one detect pregnancy with pulse rate?
yes, it can detect, your pulse rate will increase because of the volume of your blood
What is used to detect earthquakes?
A seismograph.
Devise that bounces radio waves off the ground to detect changes in elevation?
A radio altimeter bounces radio waves off the ground to detect elevation.
What is the use of thermal imaging to detect tumours in the brain?
remember it for ever as 40% of it is by imaging
What in the carotid sinuses and aortic arch detect increases in blood pressure?
baroreceptors
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.

How is cholelithiasis diagnosed by imaging tests?
Ultrasonography, computed tomography (CT) scanning, and radionuclide imaging are able to detect the impaired functioning of bile flow and of the bile ducts.
Where are the sensory receptors sensitive to changes in oxygen levels in the blood located?
The baroreceptors, located in the carotid sinuses, respond to changes and absolute levels of blood pressure. These nerves go to centers in the brain stem and trigger changes in heart rate and venous tone.
What instrument measures blood speed?
A Doppler ultrasound is used to measure the speed of blood flow in the body. This non-invasive imaging technique uses sound waves to detect movement and produce pictures of blood vessels and the flow of blood within them.
What type of medical equipment uses infrared imaging?
Digital infrared thermal imaging (DITI) cameras use infrared imaging to give thermographs that are used to diagnose different ailments, detect cancers and monitor the healing process. The medical infrared thermographic cameras were adapted from industrial equipment to be more affordable.
What can obstetrical ultrasound examinations detect?
Doppler ultrasonography can detect the direction, velocity, and turbulence of blood flow. It is frequently used to detect problems with heart valves or to measure blood flow through the arteries.
Who do you use X-ray in medicine now?
X-ray imaging is used in hospitals to detect fractures to bone, as well as abnormalities to soft tissues
What are the benefits of thermal imaging cameras?
Thermal Imaging cameras work on a 14,000nm wavelength, which is perfect for working in poorly lit (dark) places due to their ability to capture heat emitted by objects (hence not requiring light for the camera to detect objects). Basic thermal imaging cameras cost $1,000-$2,000. Specialized thermal imaging cameras (such as those used by fire departments) cost around $9,000 each.
What is Neuroimaging?
It is the use of x ray studies and magnetic resonance imaging (MRIs) to detect abnormalities or trace pathways of nerve activity in the central nervous system
