There are many things people can do to prevent blood from clotting inside the blood vessels. One of those is making sure you don't sit/laydown very long. For example, when you take a plane ride, it is smart to get up and move around because having your legs down for so long makes your blood slow down (blood pooling) and it makes it easier for clotting to accur.

Cardio Vascular diseases occur mostly due to clotting of blood within the vascular system leading to blockages and eventually a heart attack (myocardial infaction). Anti-coagulants are chemicals which prevents clotting of blood.
No. If your body is healthy, it regulates your blood potassium level within a very tight range. If your potassium level were abnormal, clotting would be the least of your problems. This is frequently confused for two reasons: First, vitamin K levels do have a significant effect on clotting and the chemical symbol for potassium is "K". Second, some drugs that are used to control clotting can affect your potassium levels, so people may incorrectly pass on advice from their doctors about potassium and clotting that only applies to them because of the specific medications they take.
An unhealthy diet can contribute to hardening of the arteries. It can also tax the heart with too much body mass due to obesity. Also, our blood has a precise balance of clotting and anti-clotting chemicals so that it doesn't clot within the blood vessels themselves. A dietary imbalance can change that equilibrium.

Bursae is NOT found around blood vessels, it may be connected to synovial join cavity or separate from it.They form where tendon or ligament rubs against other tissues, they may appear deep to the skin, covering a bone or lying within other connective tissueexposed to friction or pressure.They aid in reducing friction and act as shock absorbers.Bursae that develope in abnormal locations, or because of abnormal stresses are called adventitious bursae.
