What do carotid bodies and aortic bodies detect?
The carotid and aortic bodies are the sensory organs for monitoring arterial blood oxygen (O2) and carbon dioxide (CO2) levels. The type I cells, which are of neuronal phenotype, are the primary site of sensory transduction in the carotid and aortic bodies.
Can you detect antibodies in saliva?
Studies to detect antibodies in saliva have been successfully used to monitor exposure to Norovirus (8), HIV (9) and also malaria parasite infections (10), as these antibody profiles match well with those found in blood.
Do current pap smears detect uterine cancer?
The Pap test does not screen for uterine cancer. Screening is when a test is used to look for a disease before there are any symptoms. Diagnostic tests are used when a person has symptoms.
How do ants detect food?
Ants, like other insects, use chemosense to detect sugar and other food. They have the ability to detect chemical substances in their environment. When these chemicals are present (even at low concentrations), they can be detected as smells by the olfactory receptors — small bristles on the insect’s body.
Can ultrasound detect ruptured implant?
We found ultrasound to be a quick, reliable, cheap and safe method of screening for implant rupture which can be used to reassure an anxious patient that her implants are intact.

What is the best scan to show cancer?
A CT scan (also known as a computed tomography scan, CAT scan, and spiral or helical CT) can help doctors find cancer and show things like a tumor’s shape and size. CT scans are most often an outpatient procedure. The scan is painless and takes about 10 to 30 minutes.
How sensitive are doctors urine pregnancy tests?
The accuracy rate for urine pregnancy tests, either at home or at the doctor’s office, is about the same. Both have the same degree of accuracy, which manufacturers say is about 99%.
What do aortic bodies detect?
Aortic bodies are more sensitive detectors of total arterial blood oxygen content than the carotid body chemoreceptors, which are more sensitive detectors of the partial pressure of oxygen in the arterial blood.
What do ants do when they find food?
Once they find a food source, they lay down more chemicals which the rest of the colony will use to make their way back to that food source until that source is depleted. Ants follow the pheromone trail using their antennae, which will feel along the ground to sense the chemicals.
What does it mean if it says suspicious activity?
If you describe someone or something as suspicious, you mean that there is some aspect of them which makes you think that they are involved in a crime or a dishonest activity.

What are aortic and carotid bodies what is their function in the respiratory system?
The aortic bodies located near the arch of the aorta also respond to acute changes in the partial pressure of oxygen, but less well than the carotid body responds to changes in the partial pressure of carbon dioxide. The aortic bodies are responsible for many of the cardiovascular effects of hypoxia.
How do you detect ionizing radiation?
Detecting radiation is achieved through the use of a variety of instruments. The most common type of radiation detector is a Geiger-Mueller (GM) tube, also called a Geiger counter.
Can you diagnose OCD yourself?

Where are osmoreceptors located and to what stimulus do they respond?
Osmoreceptors (Fig. 4-11) located in the hypothalamus (and also in the carotid artery) are capable of sensing the concentrations of solutes, particularly sodium ion. This leads to a secretion of vasopressin.
What do carotid bodies detect?
The carotid bodies are sensory organs that detect the chemical composition of the arterial blood. The carotid body sensory activity increases in response to arterial hypoxemia and the ensuing chemoreflex regulates vital homeostatic functions.
How do I know if I have lead in brass?
The standard lead-free brass fittings are made with marine-grade DZR brass and are currently acceptable under the Safe Drinking Water Act, but will be restricted to non-potable water applications as of 2014.

How far do ants smell food?
Ants can smell food from far away, and most of the ants could pick up a scent from 10.8 ft (3.3 m) away. Even some can sense as far as 19.3 ft (5.9 m). This strong sense of smell helps them in many ways. Ants can also detect sugar from far away.
