They are both the main components of our body. The basic difference between blood and lymph is that blood is made up of various types of cells such as red blood cells, white blood cells, and platelets. While Lymph is a colorless liquid that lacks RBCs (red blood cells) but has WBCs (White blood cells) and fewer platelets. The blood supplies oxygen gas to several sections of the body, whereas the lymph supplies nutrients such as fat-soluble vitamins and fats in the form of chylomicrons. Blood circulates throughout the body through the circulatory system while lymph runs through the lymphatic system. Lymph is basically derived from the blood by super filtration through capillaries.
Blood present in our body is the only liquid connective tissue and plays a critical role in transporting a wide variety of substances to different parts of the body. It also allows oxygen to circulate throughout the body. On the other hand, lymph helps fight infection and remove waste products.
Difference Between Blood And Lymph In Tabular Form
|Definition||Blood is a reddish fluid.||Lymph is a colorless fluid.|
|What is it?||Blood is the opaque red fluid that runs through the blood vessels. It carries waste products from tissues, transmits carbon dioxide to the lungs from which it is released.||Lymph is a translucent fluid that circulates through the lymphatic vessels. It contains leukocytes whose function is to fight bacteria.|
|The process occurs in||The circulatory system.||Lymphatic system.|
|Functions||Participates in the circulation of nutrients, hormones, oxygen and carbon dioxide, waste, and other toxins. It also maintains body temperature and pH. Blood prevents any increase in the acidity or alkalinity of the body.||It helps in the defense of the body and is part of the immune system. Lymph stores lymphocytes, and transports fat and fat-soluble vitamins.|
|Nutrient supply||Many nutrients are supplied to different organs.||Several nutrients are supplied from cells, tissues to the blood, through the lymphatic vessels.|
|Clot formation||It clots quickly due to the presence of more fibrinogen.||It clots slowly due to the presence of less fibrinogen.|
What is Blood?
Blood is the opaque & fluid that runs through the blood vessels. It is also the body’s means of transport, through which all tissues are supplied with food and oxygen that they need for their growth and repair of damage. While blood distributes the secretions or hormones manufactured through the important glands of the body, taking them to all the organs where they are needed. This with the purpose that such bodies can carry out their specific functions. Blood carries waste products from the tissues, carries carbon dioxide to the lungs from which it is released at the same time. The remaining materials are carried to the kidneys from which elimination takes place outside the body.

Components of blood and their functions
The main components of blood include red blood cells, white blood cells, blood platelets, and plasma. Blood is the main component of the human circulatory system.
Blood has many different functions, some important functions of blood are listed below:
- Regulates the water content of cells.
- Corporal temperature regulation.
- Regulates pH by interacting with acids and bases.
- Protects against excessive blood loss through clotting.
- Involved in the transport of hormones, respiratory gases, nutrition, enzymes, and other molecules to the respective parts of the body.
What is Lymph?
It is a translucent fluid that circulates through the lymphatic vessels. The lymph is occurred in the capillaries of the blood and fills all the spaces in the cells of the body. In the intercellular spaces, the lymph is emptied into the lymphatic capillaries, which it passes to larger lymphatic vessels. These vessels join together to form larger and larger vessels. It results in the production of the lymphatic ducts, thoracic and right, which are located below the clavicle. There are lymph nodes found between the ducts, appearing as clusters wrapped in connective tissues. The lymph consists of leukocytes whose function is to fight bacteria. Their glands also filter infectious material and other wastes from the tissues and act as the body’s defense against the spread of infection. Lymphatic tissues are also found in the digestive tract and is lactiferous that absorbs fat from digested food, taking it from the small intestine.

It also serves an important role in transporting white blood cells within lymph nodes and bones, removing interstitial fluid from tissues, and also fighting infectious and disease-causing bacteria that invade blood cells. There are some other important lymph functions are listed below:
- Removes metabolic waste from tissue cells.
- It also maintains the composition of the tissue fluid.
- It provides nutrients to the body.
- It helps to invade the entry of pathogenic infections caused by microbes.
- It absorbs fat-soluble vitamins and other digested fat molecules from the small intestine through the lymphatic vessels.
