Questions Related to body fluids and circulation

Which of the following cells are derived from myeloid progenitors?

production of blood cells body fluids and circulation biology

  1. Macrophages

  2. Megakaryocytes

  3. Granulocyte

  4. All of the above

Show answer
Correct Option: D
Explanation:
Hematopoietic stem cells of bone marrow give rise to myeloid and lymphoid progenitor cells.  Myeloid progenitor cells include macrophages, megakaryocytes, granulocytes, platelets, and erythrocytes. Thus the correct answer is option D.

Blood bank of human body is

production of blood cells body fluids and circulation biology

  1. Spleen

  2. Liver

  3. Bone

  4. Kidney

Show answer
Correct Option: A
Explanation:

Spleen is the blood bank of human body as it has the capacity to store considerable amount blood, that can be released in a situation of emergency (about a cup).

So, the correct answer is 'Spleen'

Total oxygen that can be carried by blood is?

  1. $1000-1200$ ml

  2. $2000-3000$ml

  3. $200$ml

  4. $100$ml

Show answer
Correct Option: A

In normal healthy individuals , the percentage of adult and fetal haemoglobin , HbA : HbA2 : HbF is ____________.

production of blood cells body fluids and circulation biology

  1. 96 :2 : 2

  2. 45 : 45 : 10

  3. 50 : 45 : 5

  4. 80 : 10 : 10

Show answer
Correct Option: A

Choose correct alternative in the following statements:
Nucleus is absent in

production of blood cells body fluids and circulation biology

  1. RBCs

  2. WBCs

  3. All blood cells

  4. Liver cells

Show answer
Correct Option: A
Explanation:

The nucleus is absent in red blood cells in order to accomodate more space for haemoglobin. It also allows the cell to maintain its biconcave shape which aids diffusion. 

Hence, the correct answer is 'RBCs' .

Cells formed in bone marrow include

production of blood cells body fluids and circulation biology

  1. RBC

  2. RBC and leucocytes

  3. Leucocytes

  4. Lymphocytes

Show answer
Correct Option: B
Explanation:
RBCs (Red blood cells) or erythrocytes transport oxygen in the body and formed in bone marrow. They are roughly circular and lack nucleus and other organelles.
Leucocytes or white blood cells (WBCs) may be granular or agranular. Granulocytes include basophils, eosinophils, neutrophils and agranulocytes include monocytes and lymphocytes. These cells are also formed in bone marrow. 
So, the correct answer is 'RBC and leucocytes'.

Hepatic portal system is found in

types of circulatory system circulatory pathways transportation in plants and circulation in animals body fluids and circulation biology

  1. All mammals

  2. All amniotes

  3. All vertebrates

  4. Higher invertebrates

  5. None of these

Show answer
Correct Option: A
Explanation:

A) The hepatic portal system is the venous system that returns blood from the digestive tract and spleen to the liver. It is present in mammals.

B) Not all amniotes have a hepatic portal system.
C) The hepatic portal system is found in amphibians and mammals.
D) Higher invertebrates do not have a hepatic portal system.
E) Mammals have a hepatic portal system.
So the correct answer is 'All mammals'.

Animals of which phylum contains open circulatory system?

types of circulatory system circulatory pathways transportation in plants and circulation in animals body fluids and circulation biology

  1. Arthropoda

  2. Annelida

  3. Hemichordata

  4. Both (a) and (c)

Show answer
Correct Option: D
Explanation:

Both Hemichordata and Arthropoda has an open circulatory system. In this system the heart pumps blood into an open cavity called a hemocoel.


How many of the examples mentioned posses closed (C) and open(O) circulatory system?

Cephalopod molluscs, non-cephalopod molluscs, Chordates, Annelids, Tunicates, Hemi-chordates and Arthropods

Correct Option: A

Humans have a

types of circulatory system circulatory pathways transportation in plants and circulation in animals body fluids and circulation biology

  1. Closed circulatory system

  2. Circulatory system

  3. Open circulatory system

  4. None of the above.

Show answer
Correct Option: A
Explanation:

The circulatory patterns are of two types open or closed. Open circulatory system is present in arthropods and molluscs in which blood pumped by the heart passes through large vessels into open spaces or body cavities called sinuses. Annelids and chordates (example humans) have a closed circulatory system in which the blood pumped by the heart is always circulated through a closed network of blood vessels. This pattern is considered to be more advantageous, as the flow of fluid can be more precisely regulated.
