Explanation
The chordae tendineae are a group of tough, tendinous strands in the heart. They are commonly referred to as the “heart strings” since they resemble small pieces of string. Functionally, the chordae tendineae play a vital role in holding the atrioventricular valves in place while the heart is pumping blood. Thus damaged chordae tendineae of tricuspid valve will reduce flow of blood into pulmonary artery. Answer : (c)
Q.9
Starlin's law of heart ... ... [ WB 2008]
0%

d) Greater the minute volume, greater is the heart rate.
Explanation
Starlin's law of heart “As a larger volume of blood flows into the ventricle, the blood will stretch the walls of the heart, causing a greater expansion during diastole, which in turn increases the force of the contraction and thus the quantity of blood that is pumped into the aorta during systole”. The increased volume of blood stretches the ventricular wall thus increases length of cardiac fibres, causing cardiac muscle to contract more forcefully Answer : (b)

Thus assertion is true and statement of reasoning is also true but reasoning is not a explanation for assertion Answer : (b)
Q.13
Parents with blood group O and AB can not have AB child as .... [ MPPMT 1992 ]

0%
b) Gene for O is dominant over gene for A
0%
c) Genes for A and B are absent in one of parents
0%
d) Gene for A or B is present in one of the parents
Explanation
The A allele codes for an enzyme that makes the A antigen, and the B allele codes for an enzyme that makes the B antigen. A third version of this gene, the O allele, codes for a protein that is not functional; it makes no surface molecules at all. Everyone inherits two alleles of the gene, one from each parent. The combination of your two alleles determines your blood type. Now since group O don not have A or B allele child cannot have AB group Answer : (c)

The hepatic portal vein or portal vein is a blood vessel that carries blood from the gastrointestinal tract, gallbladder, pancreas and spleen to the liver. This blood is rich in nutrients that have been extracted from food, and the liver processes these nutrients; >br/> it also filters toxins that may have been ingested with the food. 75% of total liver blood flow is through the portal vein, with the remainder coming from the hepatic artery proper. The blood leaves the liver to the heart in the hepatic veins. Answer : (b)
