Blood vs. Lymph — What's the Difference?

Blood is a body fluid in humans and other animals that delivers necessary substances such as nutrients and oxygen to the cells and transports metabolic waste products away from those same cells.In vertebrates, it is composed of blood cells suspended in blood plasma. Plasma, which constitutes 55% of blood fluid, is mostly water (92% by volume), and contains proteins, glucose, mineral ions, hormones, carbon dioxide (plasma being the main medium for excretory product transportation), and blood cells themselves.

Lymph (from Latin, lympha meaning "water") is the fluid that flows through the lymphatic system, a system composed of lymph vessels (channels) and intervening lymph nodes whose function, like the venous system, is to return fluid from the tissues to the central circulation. Interstitial fluid – the fluid between the cells in all body tissues – enters the lymph capillaries.

The fluid consisting of plasma, blood cells, and platelets that is circulated by the heart through the vertebrate vascular system, carrying oxygen and nutrients to and waste materials away from all body tissues.

A clear, watery, sometimes faintly yellowish fluid derived from body tissues that contains white blood cells and circulates throughout the lymphatic system, returning to the venous bloodstream through the thoracic duct. Lymph acts to remove bacteria and certain proteins from the tissues, transport fat from the small intestine, and supply mature lymphocytes to the blood.

A similar fluid in animals other than vertebrates.

An alkaline colorless fluid, contained in the lymphatic vessels, coagulable like blood, but free from red blood corpuscles. It is absorbed from the various tissues and organs of the body, and is finally discharged by the thoracic and right lymphatic ducts into the great veins near the heart.

Family relationship; kinship.

A fibrinous material exuded from the blood vessels in inflammation. In the process of healing it is either absorbed, or is converted into connective tissue binding the inflamed surfaces together.

Descent from noble or royal lineage

A fluid containing certain products resulting from the growth of specific microorganisms upon some culture medium, and supposed to be possessed of curative properties.

Recorded descent from purebred stock.

A family relationship due to birth, such as that between siblings; contrasted with relationships due to marriage or adoption (see blood relative, blood relation, by blood).
