Multiple choice biology soldiers of defense human lymphatic system lymph and its function lymph and tissue fluid

Which of the following has the similar composition as lymph?

  1. Red blood cells

  2. Blood plasma

  3. White blood cells

  4. Nutrients

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Lymph is the interstitial fluid present in the tissue space and it has accumulated due to the pressure difference between the arteries and the veins. It has a composition similar to that of the blood plasma, that it contains small solutes, water ions, proteins lymphocytes etc.

A. Red blood cells are the formed elements, containing the respiratory pigment called haemoglobin.
B. Blood plasma is the fluid part of the blood, whose composition is similar to that of the blood.
C. White blood cells are the formed elements involved in the immunity.
D. Nutrients are the food ingredients.
Hence, the correct answer is 'Blood Plasma'

Which of the following has the similarities with the lymph?

  1. Red blood cells

  2. Blood plasma

  3. White blood cells

  4. Nutrients
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Since the lymph is derived from the interstitial fluid, its composition continually changes as the blood and the surrounding cells continually exchange substances with the interstitial fluid. It is generally similar to blood plasma, which is the fluid component of blood. Lymph returns proteins and excess interstitial fluid to the blood stream. Lymph may pick up bacteria and bring them to lymph nodes, where they are destroyed. Metastatic cancer  cells can also be transported via lymph. Lymph also transports fats from the digestive system (beginning in the lacteals) to the blood via chylomicrons.


So, the correct option is 'Blood plasma'.

Which of the following molecule enters into the lymph from intestine?

  1. Fat molecules

  2. Glycerols

  3. Plasma protein

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
  • Chyle is the liquid form of chyme that enters lymph vessels from the small intestine. It is rich in fats, these fats along with lymph often appear as milk. The fat molecules from the intestine will make their way into the lymph.
  • Glycerols also called as glycerine is a colorless, odorless substance. It is found as an intermediate in metabolic pathways.
  • Plasma protein is the proteins that make-up blood plasma. They help in maintaining osmotic pressure, clotting, and transport of certain lipids, enzymes and hormones.
So the correct option is "Fat molecules".

Lymph transports white blood cells from

  1. Spleen

  2. Pancreas

  3. Lymph nodes

  4. liver

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

A. Spleen also referred to as the graveyard of RBCs removes worn-out RBCs and fights infections. It is a part of the lymphatic system

B. Pancreas The lymphatic system of pancreas drains excess fluid that contains leaking hormones and some enzymes from interstitial spaces.
C. Lymph nodes filter the lymph as it passes through these nodes. They board lymphocytes which help in removing wastes and antigens. In case of infection, lymph nodes transport WBCs to blood
D. Liver produces a large amount of lymph, the lymphatic system of liver functions as a tissue drainage system and immunological control system. 
So the answer is C

Lymph is more similar to

  1. Blood

  2. Interstitial fluid

  3. Both A and B

  4. None of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Interstitial fluid is present in the extracellular matrix by the difference in the pressure of the arteries and veins. This interstitial fluid forms lymph that flows in the lymphatic capillaries. These are similar in their composition of proteins, water, and the lymphocytes. Blood flows in the blood vessels and has more proteins than interstitial fluid and lymph. Blood also has the RBCs that are absent in interstitial fluid and lymph. 

Hence, the correct answer is 'Interstitial fluid'.

Which of the following removes debris from cells?

  1. Blood

  2. Lymph

  3. Interstitial fluid

  4. All of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
The lymphatic system can be compared with "hazardous waste disposal" because it transports waste products out of the body. These include, for example, proteins, metabolic breakdown products, inflammatory products or fat from the abdominal cavity. The lymphatic system runs alongside the blood vessels and covers our entire body like a net. Lymph fluid normally flows through the network of lymph vessels that connect to a group of lymph nodes. The nodes act as a filter, destroying or trapping anything harmful that the body doesn’t need. The lymph nodes contain white blood cells (lymphocytes), which attack and break down bacteria, viruses, damaged cells or cancer cells. Waste products and the destroyed bacteria are then carried in the lymph fluid back into the bloodstream and are removed from the body with other body waste.

So, the correct answer is 'Lymph '.

Lymph is responsible for removal of

  1. Antigens

  2. Toxins

  3. Interstitial fluid

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

  • Antigens are foreign particles that stimulate immune response activating the immune system and WBCs. Antigens are carried by lymph to lymph nodes where they are taken care by lymphocytes.
  • Toxins are metabolic wastes or substances secreted by bacteria, viruses or fungi which can be harmful and have to be excreted from the system. Toxins in the interstitial fluid are removed by lymph.
  • Interstitial fluid is the extracellular fluid in which cells are bathed. They contain metabolic wastes and CO2 which are absorbed into venules. The left out interstitial fluid is removed by lymph vessels.
So, the correct answer is "All of the above".
