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.
Veins carry blood from the heart to the body. Capillaries are made of very thin walls. The walls have small openings through which leukocytes (white blood cells) and plasma (liquid part of blood) can leak out to form tissue fluid. The lumen is very small (10 micrometers across) so capillaries can fit into tiny spaces.eins carry blood from the heart to the body. Capillaries are made of very thin walls.
