What is found in the lymph?

Lymph contains white blood cells called lymphocytes (LIM-fuh-sites) and chyle (KYE-ul), which is made of fats and proteins from the intestines. This is important because water, proteins, and other substances are always leaking out of tiny blood capillaries into the body tissues around them.

Is lymph found in blood?

Lymph is a fluid similar in composition to blood plasma. It is derived from blood plasma as fluids pass through capillary walls at the arterial end. As the interstitial fluid begins to accumulate, it is picked up and removed by tiny lymphatic vessels and returned to the blood.

What are the 5 lymph nodes?

How many sentinel lymph nodes are in the body?

The number of lymph nodes in the axilla varies from person to person; the usual range is between 20 and 40. Historically, all of these axillary lymph nodes were removed (in an operation called axillary lymph node dissection, or ALND) in women diagnosed with breast cancer.
