Question

Write the difference between blood, lymph and serum.

Answer 1

Blood : It is reddish coloured vascular tissue that flows inside blood vessels by means of pumping activity of heart, pH is 7.4. Colour is bright red in oxygenated form and purple in deoxygenerated form Blood has two parts, fluid plasma (55%) and blood cells (45%). 

There are three types of blood cells

1. Red blood Cells.

2.White blood cells.

3.Blood Platelets.

Lymph : It is light yellow fluid connective tissue which is formed from tissue fluid and filtered out blood. Lymph is devoid of red blood corpuscles and blood platelets. Proteins are fewer, so are white blood corpuscles. However, lymphocytes are most abundant. Lymph flows lymph capillaries and lymph vessels. All places they pass through lymph nodes and lymph organs where lymphocytes multiply and mature. They are also sites for entrapping microbes. Lymph’s is ultimately passed into blood. Most of the organs and tissues pour their secretions and excretions into lymph instead of blood. Lymph’s is middle man between tissues and blood.

Serum: Serum is plasma from which fibrinogen is removed.

Answer 2

Difference between blood,lymph and serum

Explanation:

• Blood:- Blood is the only fluid connective tissue present in our body and plays a significant role in transporting a wide variety of substances to different parts of the body.
• The composition of blood are RBC,WBC,Plasma and Blood platelets.blood is the main component of the human circulatory system.
• The main functions of blood include: - Regulates body temperature.
• Regulates the water content of the cells.

• Lymph:- Lymph is a clear white colours fluids tissue which is composed of lymphocytes, white blood cells. Lymph is generally found in the lymphatic vessels and in the various cavities of the body.
• It is the part of the lymphatic system, which functions by transporting the white blood cells between the lymph nodes and bones, removal of interstitial fluid from tissues and fights against the disease-causing and infectious bacteria invading the blood cells.

• The main functions of lymph include:  - Supplies nutrients to the body.
• Maintains the composition of tissue fluid.

• Serum:- Serum is the most important part of blood. They contain 6-8% of the proteins that make up blood. They are more or less equally divided between serum albumin and serum globulins.
• When blood is extracted and left to clot, the clot shrinks after some time.
• The main function of serum:- The serum is squeezed out once this clot shrinks. The proteins in the serum are usually separated by a process called electrophoresis.
