The alveoli, or air sacs, of the lungs. Blood is returned by veins to the vena cava, and to the right atrium of the heart. The blood is pumped by the heart's right ventricle to the lungs through the pulmonary arteries. The pulmonary veins return the oxygenated blood to the left atrium, where it is pumped by the left ventricle into the body's arteries through the expanded artery called the aorta.

What does oxygen rich mean?
acidoticBlood that is rich in oxygen is called saturated or oxygenated. Oxygen saturation is a measure of the amount of oxygen that is dissolved in blood. Please see the related link for details.It is called oxygenated or arteriolar blood. Even in the pulmonary vein it is called arteriolar blood because it is oxygenated.
Why do rockets need to carry a supply of oxygen?
Rockets need to carry a steady supply of oxygen so that the fire that takes them off of the ground can burn. You must remember that to have fire you must have oxygen.
Why is it important for blood to be delivered to every cell in your body?
Blood is a transport fluid. It mainly transports oxygenated blood (blood containing oxygen) from the heart around the body to every cell. Carbon dioxide, which is a waste produced in cellular respiration, is removed from the cell into the blood, and replaced with oxygen. The carbon dioxide is then transported in deoxygenated blood (blood containing carbon dioxide) towards the heart and lungs (through veins) to be expelled from the body. So basically, blood must be delivered to cells in the body to supply oxygen for cellular activities, supply essential nutrients to the cell, and remove waste products (such as carbon dioxide) from the cell.
Why are there blood capillaries close to all the cells in your organs?
You have 100,000 feet of blood vessels in your body. The tinest ones must be close to the cells. Each cell needs a constant supply of oxygen and glucose and other nutrients and must have means to remove wastes that they make.
Where does the oxygen enters and carbon dioxide leaves?
Oxygen must enter our blood and Carbon Dioxide must leave the blood through our lungs. They do so by diffusion between the cappillaries.
What must the heart be supplied with?
Oxygen, Blood, Iron and Minerals
Why is caffeine not good for you on your period?
During menstruation the blood volume of a woman decreases and so it is important to not put great oxygen demand on the heart which demands more blood flow. blood demand and blood supply must be insint or balance. The caffeine increase heart rate which put unnecessary pressure on the heart to supply more blood that is not present in the body. this can damage the heart over time.

Why does the heart muscle need oxygenated blood?
the heart is a muscle, and every muscle needs blood because the blood caries oxygen to the cells of that muscle which is then converted into energy and this is what makes our bodies work. your heart however is a special muscle that pumps your blood to all of the muscles in your body.
What 3 conditions must be satisfied to maintain a fire?
A fire must have an adequate supply of heat, fuel, and oxygen to sustain it.
What is the role of the blood vessels on the outside of a heart?
Capillaries are the smallest of a body's blood vessels, measuring 5-10 μm(Micrometre) in diameter, which connect arterioles and venules, and enable the interchange of water, oxygen, carbon dioxide, and many other nutrient and waste chemical substances between blood and surrounding tissues.
How oxygen content in human blood is calculated?
first we must measure the haemoglobin .each gm. of human hemoglbin carries 1.39ml oxygen in a 100ml blood. in addition o.0003 ml oxygen will be dissolved in blood at 1mmhg pressure of delivered oxygen.
