Questions Related to lymph and its function

Most of our cells are surrounded by- 

  1. Blood

  2. Fluid equivalent to seawater in salt composition

  3. Interstitial fluid

  4. Pure water


Correct Option: C
Explanation:
It is the main component of the extracellular fluid and transcellular fluid. The interstitial fluid is found in the spaces between cells or the tissue spaces.It consists of a water solvent containing sugars, salts, fatty acids, amino acids, coenzymes, hormones, neurotransmitters, white blood cells and waste products from the cell.The composition of tissue fluid depends upon the exchanges between the cells in the biological tissue and the blood. 
So, the correct answer is Interstitial Fluid."

Which of the following statements is/are incorrect about lymph?
(i)Lymph is colourful as it has haemoglobin but no RBC.
(ii)It contains specialised lymphocytes which are responsible for immunity of the body.
(iii)Lymph is an important carrier for nutrients and hormones.
(iv)Fats are absorbed through lymph in the lacteals present in the intestinal villi.

  1. i only

  2. iii and iv

  3. ii and iii

  4. iv only


Correct Option: A
Explanation:

Lymph is colourless as it does not contain RBC, in higher animals the respiratory pigment haemoglobin is contained only in the RBC and does not occur dispersed in body fluids. Therefore, statement i is wrong.

So, the correct answer is 'i only'

Compared to blood our lymph has

  1. Plasma without proteins

  2. More WBCs and no RBCs

  3. More RBCs and less WBCs

  4. No plasma.


Correct Option: B
Explanation:

Lymph consists of proteins- albumin, fibrinogen etc, nitrogenous waste, WBCs, lymphocytes, carbohydrates, fats and 94% water. It does not contain RBCs that are found in abundance in blood and platelets.

So, the correct answer is 'More WBCs and no RBCs'

The lymph serves to

  1. Return the interstitial fluid to the blood

  2. Return the WBCs and RBCs to the lymph nodes

  3. Transport $CO _2$ to the lungs

  4. Transport $O _2$ to the brain


Correct Option: A
Explanation:

Lymph is in contact with the cells/tissues of the organs as interstitial fluid, this fluid is drained in the lymphatic vessels, that connects to the venous system. In this manner interstitial fluid is returned to the blood.

So, the correct answer is 'Return the interstitial fluid to the blood'

Which of the following statements is true for lymph?

  1. WBCs + serum

  2. Blood - RBCs and some proteins

  3. RBCs + WBCs + plasma

  4. RBCs + proteins + platelets


Correct Option: A
Explanation:

Lymph has a pale yellow colour due to absence of RBCs and platelets,  it has abundance of WBCs, Lymphocytes, carbohydrates, proteins, fats and nitrogenous waste.

So, the correct answer is 'WBCs + serum'

In the human circulation, the lymph

  1. Transports oxygen to brain

  2. Transports $CO _2$ to lungs

  3. Returns interstitial fluid back to heart

  4. Contains RBCs, leucocyte, and more protein as compared to blood


Correct Option: C
Explanation:

Lymphatic system is a network present throughout all tissues in the body. It removes wastes, bacteria and excess water from the tissue fluid. The fluid present in the lymphatic vessels is called as lymph. In lymph, escaped blood cells and proteins are collected and returned back to the heart in the form of interstitial fluid. Interstitial fluid is a fluid that bathes the cells of multicellular animals.

Thus, the correct answer is 'Returns interstitial fluid back to heart.'

All of the following organs in the human body are located both on the right and the left sides, except

  1. Spleen

  2. Kidneys

  3. Lungs

  4. Eyes


Correct Option: A
Explanation:

The spleen is the largest organ in the lymphatic system. It is an important organ for keeping bodily fluids balanced, but it is possible to live without it. The spleen is located under the ribcage and above the stomach in the left upper quadrant of the abdomen. So, the correct option is "A" (Spleen).

Which of the following is the function of lymph?

  1. Lymph keeps the body cells moist.

  2. Lymph takes lymphocytes and antibodies from the lymph nodes to the blood.

  3. Lymph maintains the volume of the blood.

  4. All of the above


Correct Option: D
Explanation:
Lymph is the fluid that circulates throughout the lymphatic system. It is a clear-to-white fluid made of White blood cells, especially lymphocytes, the cells that attack bacteria in the blood. It performs multiple functions inside our bodies. It takes lymphocyte and antibodies from the lymph nodes to the blood. It also keeps the cells moist by maintaining the blood volume.
The interstitial fluid is absorbed into the lymph vessels and again it is added to blood from the lymph, and in turn, regulates the blood volume.
So, the correct answer is 'All of the above'.

Lymph is

  1. Blood minus R.B.C

  2. Blood minus W.B.C

  3. Blood minus cells

  4. Plasma minus protein


Correct Option: A
Explanation:

Lymph is a liquid made up of plasma, WBCs, clotting factors but does not contain RBCs and form a system in a body known as lymphatic system and flows in lymph capillaries. It transports fatty acid in the form of chyle through the digestive system and WBCs through lymph nodes to bones.

So the correct option is 'Blood minus R.B.C.'

Which of the following cells of connective tissue is/are absent in blood and lymph?

  1. Antibody secreting cells

  2. Phagocytic cells

  3. Histamine secreting cells

  4. Fibre secreting cells


Correct Option: A
