Question 1

Name the two fluids that circulate in the body.

Answer :

Blood and lymph are the major fluids and are present in large amounts in the body.

Question 2

In a coloured diagram, why do we generally show the pulmonary artery in blue and pulmonary vein in red colour ?

Answer :

Conventionally, in a coloured diagram we show the pulmonary artery in blue because it carries the deoxygenated blood from the heart to the lungs, whereas, pulmonary vein is shown by red colour because it carries oxygenated blood from the lungs to the heart for circulation.

Question 3

Name any four substance transported by blood.

Answer :

Any four substances that are transported by blood are:
 

(a) Digested food from the alimentary canal to the tissues.

(b) Oxygen from lungs to tissues.

(c) Carbon dioxide from tissues to lungs.

(d) Hormones secreted by endocrine glands to required organs.

Question 1

Name the following :

(i) The yellow coloured fluid part of the blood.

(ii) The respiratory pigment contained in RBCS.

(iii) Any two organelles absent in mature RBCS

(iv) The process of WBCs squeezing out through the walls of the blood capillaries.

Answer :

(i) Plasma is a clear, yellowish colour fluid.

(ii)  Haemoglobin is a respiratory pigment in human beings contained in RBC.

(iii) RBCs /(Red blood cells)  need to remove cell structures like their nucleus, mitochondria, ribosomes  upon maturity in order to carry oxygen very efficiently to the cells, utilising space vacant by these cell structures.

(iv) The process of WBCs squeezing out through the walls of the blood capillaries: Diapedesis 

Question 2

Mention the following :

(i) Average life span of RBCs.

(ii) Range of RBCS per mm in a normal adult human female.

(iii) The two major categories of WBCs.

(iv) Blood cells involved in leukaemia.

Answer :

(i) Average lifespan of an RBC is 100-120 days.

(ii) Range if RBCs per mm3 in a normal adult human female is about 4.5 million.

(iii) The two major categories of WBCs are granular and non granular.

(iv) White blood cells.

Question 1

State which of the following statements are True.

Advertisement

(i) Process of coagulation starts with the release of a substance from RBCs.

(ii) Blood fails to clot readily in the case of deficiency of calcium.

(iii) The solid fibrin and thrombin are one and the same thing.

(iv) The clear liquid that o0zes out after the formation of a clot is serum.

Answer :

(i) False.

Statements : Process of coagulation starts with the release of a substance from platelets known as thrombokinase or thromboplastin.

(ii) True.

Statements : Blood fails to clot readily in the case of deficiency of calcium because without calcium thrombokinase will not be able to convert inactive prothrombin to active thrombin which is the major component for the production of the clot.

(iii) False.

Statements : The solid fibrin and thrombin is not the same thing. Thrombin in presence of calcium ions converts soluble fibrinogen into solid insoluble threads like structures of fibrin in the plasma.

(iv) True.

Statements : During clot formation, the blood cells get trapped in the network of fibrin which shrinks and squeezes out the rest of the plasma in form of a clear liquid called serum.

Question 2

Name the following :

(i) The category of vitamin required for clotting of blood.

(ii) Any two diseases related with blood clotting.

(iii) The antibodies present in the plasma of O type blood group.

(iv) The animal for which Rh stands in the context of blood group.

Answer :

(i) The category of vitamin required for clotting of blood: Vitamin K

(ii) Any two diseases related with blood clotting: Blood blister and viral dengue fever (haemorrhage)

(iii) The antibodies present in the  plasma of O type blood group: A and B

(iv) The animal for which Rh stands in the context of blood group: Rhesus (common monkey).

Question 1

Fill in blanks :

(i) Ventricles have …………. walls when compared with those of auricles.

(ii) Ventricles give rise to two large blood vessels called …………… and …………….

Answer :

(i) Ventricles have thick walls when compared with those of auricles.

(ii) Ventricles give rise to two large blood vessels called pulmonary artery and aorta.

Question 2

Where are the following located ?

(i) Tricuspid

(ii) Mitral valve

(iii) Pulmonary semilunar valves

Answer :

(i) Tricuspid valve is located at the aperture between the right auricle and the right ventricle.

(ii) Mitral valve also known as the bicuspid or the left artrio – ventricular valve is located in between the left auricle and the left ventricle.

(iii) Pulmonary semilunar valves are located at the opening of the right ventricle into the pulmonary artery.

Question 3

Can you answer why the pulmonary artery shown in Fig. 8.6 is blue in colour ?

Answer :

Blue colour is used for the representation of pulmonary artery because it carries deoxygenated blood from heart to lungs,

Question 1

Name the following :

(i) Contraction phase of heart.

(ii) The structure that holds the heart valves in position.

Answer :

(i) The contraction phase of the heart is known as systole. During systole, the atria contracts first followed by the ventricles.

(ii) The structure that holds the heart valves in position is known as the chordae tendinea.

Question 2

Mention the phase of heart beat in which both the atrio-ventricular valves are closed.
