how do blood cells receive oxygen?

See below: The air we breathe in has about 21% oxygen. It reaches deep in the lung and permeates the lining of the lung and blood vessels and dissolves in the liquid part of blood. From the liquid part of blood, it binds hemoglobin in the red cells. The red cells carry the oxygen for use by all organs in the body. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk prodFor good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex, if you have sex.

Should I bank my baby's cord blood?

Yes: That's actually a great idea. Stem cells from cord blood can be used to treat a number of conditions in both the child and other family members, and the number of such uses is growing exponentially.
Dr. Michael Thompson

I would suggest public banking. 1) cheaper (free), 2) provides utility for a broader group of people than just your child or family.

Dr. Herbert Duvivier

I agree with both the above comments. Given the increasing use of stem cells I don't believe you can go wrong.

Not necessarily. Cord blood banking is quite expensive and the number of disorders for which the cord blood may be used later is quite small. If you have the financial means then it is a good idea . However, cord blood allografts (from unrelated donors) are becoming more common with good results so always donate but don't fall prey to scare tactics in banking cord blood.

A 21-year-old member asked:

Once I start on supplemental oxygen, will I have to stay on it? Or, will I become addicted to supplemental oxygen?

Addiction Medicine 35 years experience
No: There is no description of an oxygen withdrawal syndrome (providing one maintains an appropriate minimum oxygen level) presumably the net benefit of chronic oxygen outweighs the net side effects so a necessary aspect of addiction does not exist.

I have hemochromatosis - can I donate blood?

3 doctor answers7 doctors weighed in
Dr. Jeffrey Crespin
Gastroenterology 28 years experience
No: Unfortunately, the red cross does not allow this blood to be donated even though there is nothing wrong with the blood. However, certain bacteria thrive on iron and that may be the red cross's rational.

Can it be normal to have some lumps of blood in your period?

Yes: The clumps are normal. Each period is the lining your endometrium that is shedding so sometimes it can be in the form of larger clots or lumps.
