The central chemoreceptors are primarily sensitive to blood levels of?
Carbon dioxide and hydrogen ions
Chemoreceptors sensitive to blood carbon dioxide levels are primarily located in the?
aortic and carotid bodies
What Blood which contains carbon dioxide and lack oxygen?
Venous blood is loaded with carbon dioxide and low in oxygen Arterial blood is rich in oxygen with little carbon dioxide
Receptors that detect carbon dioxide levels in the blood are?
Chemoreceptors detect the levels of carbon dioxide in the blood.
What type of blood cell takes carbon dioxide away?
Red blood cells take carbon dioxide (CO2) away from body tissues. The carbon dioxide is then transported to the lungs where it can be exhaled.
The breathing center in the brain is most sensitive to the?
levels of carbon dioxide in the blood. When carbon dioxide levels rise, the breathing center stimulates the muscles of respiration to increase breathing rate and depth. This helps to eliminate excess carbon dioxide and restore a balance in blood gas levels.
The central chemoreceptors are primarily sensitive to blood levels of?
Carbon dioxide and hydrogen ions
How will you describe the sequence of the oxygen carbon dioxide and blood?
Oxygen in & carbon dioxide out. The change occurs within the cells and blood carries the gasses between the lungs and the cells.
How will describe the sequence of oxygen carbon dioxide and blood flow?
Oxygen in & carbon dioxide out. The change occurs within the cells and blood carries the gasses between the lungs and the cells.
How will describe the sequence of oxygen carbon dioxide blood flow?
Oxygen in & carbon dioxide out. The change occurs within the cells and blood carries the gasses between the lungs and the cells.
How will you describe the sequence oxygen of carbon dioxide of blood flow?
Oxygen in & carbon dioxide out. The change occurs within the cells and blood carries the gasses between the lungs and the cells.
How will you describe the sequence of oxygen carbon-dioxide and blood flow?
Oxygen in & carbon dioxide out. The change occurs within the cells and blood carries the gasses between the lungs and the cells.

Why are lungs not suitable for breathing water?
Air breathers are more sensitive to changes in carbon dioxide concentration than to changes in oxygen. Regulation of ventilation is normally driven by receptors that are sensitive to dissolved carbon dioxide levels and the acidity (pH) of the blood.

How does the oxygen change to carbon dioxide?
The primary function of the respiratory system is to exchange oxygen and carbon dioxide. Inhaled oxygenenters the lungs and reaches the alveoli. Oxygen passes quickly through this air-blood barrier into the blood in the capillaries. Similarly, carbon dioxide passes from the blood into the alveoli and is then exhaled.
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.
