Blood and Lymph

Blood is a continually flowing fluid that delivers oxygen, nutrients, and waste elimination to the body. Blood is a liquid that contains a variety of proteins and cells. As a result, blood is unquestionably thicker than clean water. Lymph is a colourless fluid containing lymphocytes or white blood cells. The white blood cells are in charge of combating microorganisms that enter the body. 

Blood

Blood is a bodily fluid in the systemic circulation of humans and other animals that moves metabolic waste away from cells while delivering vital chemicals such as nutrition and oxygen to them. Blood is made up of red blood suspended in plasma.

Human blood consists of both liquid and solid components. The liquid component, known as plasma, is composed of water, salts, & protein. Plasma makes up more than half of your blood. Red blood cells, white blood cells, and platelets are all found in the solid section of your blood. RBCs transport oxygenated blood to your organs and tissues.

Monocytes are the blood’s biggest cells (averaging 15–18 m in diameter), accounting for around 7% of all leukocytes.

Formation of Blood

The bone marrow is where blood cells are created. The soft, spongy substance in the core of the bones is called bone marrow. It is responsible for the production of approximately 95% of the body’s red blood. The pelvic bones, breast bones, and spine bones contain the majority of the human body’s bone marrow.

Lymph

A lymphatic system consists of tissues, veins, and organs that operate with each other to return lymph, a colourless, watery fluid, to the human circulatory system. The lymphatic system gathers surplus fluid that flows from cells and tissues within your body and delivers it to the bloodstream, where it is allowed to flow throughout the body.

Lymphocytes are white blood cells that serve as one of the body’s primary immune cells. They are produced in the bone marrow and can be detected in the blood and lymph tissue.

The immunological system is a complicated network of immune cells, which include lymphocytes. These cells collaborate to protect the body from outside substances such as germs, viruses, and cancerous cells that might disrupt its function.

Lymphocyte Functions

Lymphocytes are immune system cells that circulate in the bloodstream. T cells and B cells are the two primary kinds of lymphocytes. B cells create antibody molecules that bind to and kill invading viruses and bacteria.

It can result in fatigue, weakness, and breathlessness. Infections are more likely when there is a paucity of healthy white blood cells (leucopenia). You may have heard the word neutropenia, which refers to decreased neutrophil numbers (a type of granulocyte needed to fight bacterial infections).

Generalised lymphadenopathy, or enlargement of the lymph nodes, and splenomegaly are symptoms of lymphocytosis. Splenomegaly is an enlarged spleen that can cause dull discomfort in the upper left side. This is mostly a physical examination finding.

The concentration of lymphocytes increases during activity and decreases below pre-exercise levels after intensive long-duration exercise, but it is not inhibited after moderate exercise. The higher lymphocyte concentration results from the recruitment of all lymphocyte subpopulations to the bloodstream.

Blood And Lymph: Difference 

Blood

• Blood has a reddish colour to it
•  It is a component of the circulatory system
• It is composed chiefly to transport minerals, vitamins, and all different nutrients, enzymes, oxygen, hormones, and carbon dioxide, as well as wastes and other pollutants
•  It is made up of plasma, RBCs, WBCs, and platelets
• It transports increased oxygen and food in the digested form
• Proteins, calcium, and phosphorus make up blood plasma
• Nutrients are delivered to several organs.
• Blood moves quickly through the blood vessels
• Because there is more fibrinogen present, the clots fast
• Blood circulates in a clockwise direction

Lymph

• Lymph is a colourless liquid
• It is a component of the lymphatic system
• It contributes to bodily defence and is a component of the immune system
• It comprises plasma as well as a lower concentration of WBCs and platelets
• It transports less oxygen and digested food
• Proteins are lacking in lymph plasma
• Nutrients are transported from cellular membranes to the circulation via lymphatic capillaries
• When compared to blood, it is extremely sluggish
• Clots slowly because there is less fibrinogen present
• Lymph flows in only one way

Conclusion 

We discussed blood and lymph, the difference between blood and lymph, and other related topics through the study material notes on the difference between blood and lymph. 

Blood is the distinctive fluid connective tissue found in human bodies, and it serves an important function in carrying a wide range of chemicals to various sections of the body. Lymph is a transparent white fluid tissue made up of lymphocytes and white blood cells. Lymph is a component of the lymphatic system that is present in lymphatic veins and other cavities throughout the body.
