The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide .
Does Covid 19 affect white cell count?
Some studies have revealed that raised white blood cell and neutrophil counts along with a fall in lymphocyte count are seen in some patients with COVID-19.
