A lymph node can be described as an oval-shaped organ of the in the immune sysytem, They act as filters or traps for foreign particles and are important in the proper functioning of the immune system. The same way any filter works, they trap the bad stuff so the good can flow through.
my sister had operation on her lymph nodes ,she has cancer what is the survival rate
One study found that only 2.6% of patients who had SLNB developed lymphedema, compared to 27% of patients who had ALND.
For stage I (early/lymph node negative), which comprises 40-45% of total cases, the five-year survival is 85-95%.
Approximately 10% to 20% of patients develop lymphedema after axillary lymph node removal. however if you get radiation your rate goes up to 50% and good chance of developing lymphedema
Sinoatrial Node (SA node)
Portside had the most survival rate
the SA node
50
The rate and pace of the heart are set by the SA node. There are backup systems in place if the SA node fails to do its job.
The sinoatrial node has an intrinsic rate of about 100 beats per minute, but it is normally down regulated by the vagus nerve.
Recent studies show that the survival rate of infant dolphins in the wild is 75%. In zoos and in aquariums, the survival rate is 86%.
The rate of P waves will be faster than the rate of QRS complexes.
