Red blood cells (also referred to as erythrocytes) are the most common type of blood cell and the vertebrate organism's principal means of delivering oxygen (O2) to the body tissues via the blood flow through the circulatory system. They take up oxygen in the lungs or gills and release it while squeezing through the body's capillaries.

How does haemoglobin supply the tissues of the body with oxygen?

Hemoglobin carries oxygen in red blood cells from the lungs to the tissues of the body. In the lungs, oxygen binds to the iron in hemoglobin to form oxyhemoglobin, which is then transported via the bloodstream to tissues where oxygen is released for cellular respiration. This process is facilitated by the concentration gradient of oxygen between the lungs and tissues.


What does the vascular system do?

Pumps blood around the body, to supply the tissues with oxygen and nutrients and to transport waste products away from these tissues.

What lack of protein will decrease oxygen supply to body tissues?

A lack of protein in the diet can lead to decreased production of hemoglobin, which carries oxygen in red blood cells. This can result in decreased oxygen supply to body tissues and lead to symptoms like fatigue, weakness, and shortness of breath.


What supply of oxygen exists in the body at any one time?

The body carries about 1-1.5 liters of oxygen in the blood and tissues at any given time. This supply is continually replenished through breathing and circulation to meet the body's oxygen demands.


What is the jobs of blood?

Blood transports oxygen (and carbon dioxide) and nutrients throughout your body to your tissues


What supply of oxygen exist in the body at any time?

The body's oxygen supply primarily comes from breathing air into the lungs, where oxygen is absorbed by red blood cells and then transported throughout the body. Additionally, oxygen is stored in the body in the form of oxyhemoglobin in the blood and myoglobin in muscle tissue. The body can also store a reserve of oxygen in the form of dissolved oxygen in the blood and tissues.


What are the uses of oxygenated blood?

oxygenated blood is used to supply tissues in the body with nutrients and if this supply decrease like during exercise your respiration will increase to supply oxygen to the blood in good percent


How does the heart supply the body with oxygen?

The heart pumps oxygen-rich blood to the entire body through the circulatory system. Blood picks up oxygen in the lungs and then is pumped by the heart to deliver the oxygen to all cells and tissues in the body. This process ensures that the body's cells have the oxygen they need to function properly.


When might your body perform fermentation processes?

Your body might perform fermentation processes when there is not enough oxygen available for aerobic respiration, such as during intense exercise or when oxygen supply to tissues is limited. In these situations, cells may switch to anaerobic fermentation to generate ATP and continue producing energy.


What do the arteries supply and to what?

They supply blood to the body. Arteries supply oxygenated blood throughout the body. Arteries carry oxygenated blood away from the heart to bodily tissues. Veins, on the other hand, carry oxygen deprived blood back to the heart.


Why is it harder to breath at higher elevations?

At higher elevations, the air pressure is lower, which means there is less oxygen available per breath. This can lead to lower oxygen levels in the blood, making it harder for the body to supply enough oxygen to tissues and organs, resulting in shortness of breath. The body may also compensate by increasing the respiratory rate to try to get more oxygen.
