By Mayo Clinic Staff. Common warts are caused by an infection with the human papillomavirus (HPV). More than 100 types of HPV exist, but only a few cause warts on your hands. Other types of HPV are more likely to cause warts on your feet and other areas of your skin and mucous membranes. Most types of HPV cause relatively harmless conditions such as common warts, while others may cause serious disease such as cancer of the cervix.
The rate at which the glomerulus produces filtrate from plasma (the glomerular filtration rate) is much higher than in systemic capillaries because of the particular anatomical characteristics of the glomerulus.
Pressure gradient. Filtration forces water and dissolved substances from the capillaries into. the interstitial fluid. Not all of this water is returned to the blood by. osmosis, and excess fluid is picked up by lymph capillaries to become. lymph. From lymph capillaries fluid flows into lymph veins (lymphatic. vessels) which virtually parallel the circulatory veins and are structurally.
