doppler ultrasound
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.
Brain scans, particularly magnetic resonance imaging (MRI), are crucial for diagnosing multiple sclerosis (MS) as they can reveal lesions or plaques in the brain and spinal cord. These lesions are caused by the demyelination characteristic of MS, where the immune system attacks the protective covering of nerve fibers. MRI can also help assess the extent of disease progression and monitor treatment efficacy by detecting new or changing lesions over time. Advanced imaging techniques like diffusion tensor imaging (DTI) may also provide insights into the integrity of white matter in the brain.
They detect waves coming off of the closest stars
yes, it can detect, your pulse rate will increase because of the volume of your blood
A seismograph.
Chemoreceptors that detect low oxygen levels in the body are located in the carotid bodies, which are small clusters of cells located near the carotid arteries in the neck, and in the aortic bodies near the aortic arch. These chemoreceptors send signals to the brain to trigger breathing adjustments to increase oxygen intake.
remember it for ever as 40% of it is by imaging
baroreceptors
MRA typically stands for Magnetic Resonance Angiography, a diagnostic imaging technique used to visualize blood vessels in the body. It is commonly used to detect abnormalities or blockages in the arteries, such as aneurysms or atherosclerosis.
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.
The pulse can be most easily found in the neck because the carotid arteries located there deliver blood directly from the heart to the brain, making the pulse stronger and easier to detect compared to other arteries in the body. Placing your fingers on the carotid artery on either side of the neck allows you to feel the pulsation of blood flow with each heartbeat.

Blood pressure receptors are found in the aorta (aortic baroreceptors) and carotid arteries (carotid sinus baroreceptors). These receptors detect changes in blood pressure and send signals to the brain to help regulate blood pressure.
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.
X-rays are used to detect broken bones in medical imaging. X-ray imaging uses electromagnetic radiation with wavelengths shorter than visible light to create images of the inside of the body, including bones.
X-rays and other imaging techniques such as CT scans and MRIs are commonly used to detect destructive changes in the bones. These imaging techniques provide detailed pictures of the bones and surrounding tissues to help diagnose conditions such as fractures, infections, tumors, and degenerative diseases.
Doppler imaging, such as in ultrasound or in a handheld device, is used to measure blood speed. This process can be used to measure, for instance, blood flow through leg arteries, or blood flow through the placenta.
