There are two blood vessels which carry the least amount of oxygen concentration viz. coronary sinus and the pulmonary artery.
Where is the lowest concentration of oxygen in the body?
As oxygen molecules diffuse into the cell, they are consumed, so that there is a progressive fall in oxygen concentration from the surface of the cell to the lowest concentration which occurs at the center of the cell.
What blood vessel has the highest oxygen concentration?
Explanation: The pulmonary veins have the greatest concentration of oxygenation, because they bring oxygenated blood from the lungs to the left atrium. They are the only veins that carry oxygenated blood. Blood in the pulmonary arteries is deoxygenated and travels from the right ventricle to the lungs for gas exchange.
Which blood vessel type has the lowest blood pressure?
Important: The highest pressure of circulating blood is found in arteries, and gradu- ally drops as the blood flows through the arterioles, capillaries, venules, and veins (where it is the lowest).
Which vessels contain the most oxygen?
The arteries deliver the oxygen-rich blood to the capillaries, where the actual exchange of oxygen and carbon dioxide occurs. The capillaries then deliver the waste-rich blood to the veins for transport back to the lungs and heart. Veins carry the blood back to the heart.
What is the OSHA standard for oxygen?
The OSHA Respiratory Protection Standard (“the Standard”; 29 CFR 1910.134) uses 19.5 percent oxygen as the level below which an oxygen-deficient atmosphere exists and requires, generally, that all oxygen-deficient atmospheres be considered immediately dangerous to life or health (“oxygen-deficient IDLH”).
How can I increase oxygen in my body?
We have here listed 5 important ways for more oxygen:
- Get fresh air. Open your windows and go outside. …
- Drink water. In order to oxygenate and expel carbon dioxide, our lungs need to be hydrated and drinking enough water, therefore, influences oxygen levels. …
- Eat iron-rich foods. …
- Exercise. …
- Train your breathing.

Which blood vessel has a high carbon dioxide concentration a low oxygen concentration?
The Pulmonary vein blood vessel carries oxygenated blood from the lungs back to the heart. Therefore, it carries the highest concentration of oxygen.
What carries oxygen-poor?
The pulmonary artery carries oxygen-poor blood to the lungs to receive oxygen. The pulmonary veins carry oxygen-rich blood from the lungs to the left atrium.
Do all arteries carry oxygen-rich blood?
Arteries usually carry oxygenated blood and veins usually carry deoxygenated blood. This is true most of the time. However, the pulmonary arteries and veins are an exception to this rule. Pulmonary veins carry oxygenated blood towards the heart and the pulmonary arteries carry deoxygenated blood away from the heart.
Which blood vessels carry blood at the highest pressure?
The force exerted by circulating blood on the walls of blood vessels is called blood pressure. Blood pressure is highest in arteries and lowest in veins.
Which blood vessel experiences the steepest drop in blood pressure?
What blood vessel experiences the steepest drop in blood pressure? Arterioles have the greatest resistance to blood flow and therefore produce the greatest drop in pressure.
Which artery is the largest and has the highest blood pressure?
The largest artery is the aorta, the main high-pressure pipeline connected to the heart’s left ventricle. The aorta branches into a network of smaller arteries that extend throughout the body. The arteries’ smaller branches are called arterioles and capillaries.
Which side of human heart is low in oxygen?
The blood entering the right side of your heart is low in oxygen. This is because oxygen is removed from your blood as it circulates through your body’s organs and tissues. Your heart then pumps the blood to your lungs so it can receive more oxygen.
Where is the biggest vein in your body?
The largest vein in the human body is the inferior vena cava, which carries deoxygenated blood from the lower half of the body back up to the heart.
What do you call the smallest blood vessels in the body?
Arterioles carry blood and oxygen into the smallest blood vessels, the capillaries. Capillaries are so small they can only be seen under a microscope. The walls of the capillaries are permeable to oxygen and carbon dioxide. Oxygen moves from the capillary toward the cells of the tissues and organs.
