How To Get Blood And Oxygen To The Brain
How it works: The process of oxygen getting into the blood goes like this. First we inhale air with oxygen in it. Little pockets in the lung called alveoli fill with the air and the oxygen diffuses into capillaries. This oxygenated blood then goes back to the heart where it is pumped around to the rest of the body. When it reaches capillary beds in our tissues the oxygen diffuses out into the tissues. ...Read more

It is not becaue: Are tiny( microcytic ) that they do not carry oxygen . It is because they do not have adequate /the right amount of iron or globulin that make up hemoglobin in them .

Heath: Stay healthy, eat right, lose weight and exercise. Don't do alcohol/tobacco. Avoid anabolics, supplements, etc. Exercise will increase blood flow to all parts of your body. An erection will increase blood flow to the penis, but only for a short time. Remember the viagra (sildenafil) ad: contact your doctor for an erection that lasts more than 4 hours. ...Read more
Need diagnosis: Blood flow to the nose is controlled by the autonomic nervous system. These nerves control the size and rate of blood flow to the mucosa of the lining of the lateral wall (turbinates) and middle of the nose (septum). Dilation of the blood vessels is a vagal response. Constriction of the blood vessels is a sympathetic (adrenaline) response. I do not think you can control these responses. ...Read more
Closed system: The left ventricle contracts sending blood into the aorta. The circulatory system is a closed loop. Blood traverses the capillary beds and returns to the right atrium. Very briefly, that's how it works. ...Read more
Seconds: If it does occur, it occurs over a matter of seconds. ...Read more
Very rare: Surprisingly enough, blood clots in the arms do not tend to be associated with pulmonary emboli as often as those clots in the legs. If your clot is in a superficial vein, it will never move, and so it poses no danger. If you have a deep clot (DVT) you need to be seen by a vascular surgeon to determine your risk of embolism and whether you need to be on a blood thinner. ...Read moreSee 1 more doctor answer
Flow/vessels/protein: Clots can form when: blood flow slows or stops, a blood vessel wall is injured or components of your blood support or promote coagulation. We are always clotting and unclotting a little. When one of the factors noted above tips the scale there is rapid propagation of clot. ...Read moreSee 1 more doctor answer

Depends: Elimination of nicotine from the body is determined by half-life. Nicotine's half-life is 24-48 hours. In general, 3 to 5 half lives are necessary to eliminate it from your system. That means from 3-6 days. The withdrawal however lats much longer since your system "craves" it . I know it hurts (i went through it a number of years ago) but it is surely worth it. Hang in there. ...Read more
No: Poor spiders - the only other creature out there hated more are snakes. Spiders are generally non aggressive and don't seek humans out to bite. If bitten it's usually a defensive reflex when disturbing a spider. The rapid increase in MRSA infections birthed the urban legend that spider bites were the cause. https://en.wikipedia.org/wiki/Anatomy_of_the_human_nose ...Read more
