Foramen ovaleA. Connects the two atria in the foetal heartB. Connects pulmonary trunk and aorta in foetusC. Is condition in which heart valves do not completely closeD. Is a shallow depression in the inter-ventricular septum |
|
Answer» Correct Answer - A In the foetal heart, foramen ovale is an opening in the inter-atrial septum which is closed in adult and represented by an oval depression called foss ovalis. In the embryonic period, a blood vessel called suctus arteriosus shunts blood from the pulmonary aorta into systemic aorta. But after birth, ductus arteriosus closes, leaving a remnant called ligamentum arteriosum. The artium and the ventricle of the same side are also separated by a thick fibrous tissue called the atrio-ventricular ceptum. |

What is the significance of hepatic portal system in the circulatory system? |
|
Answer» Hepatic portal System There .is special vascular connection that exists between the digestive tract and live: in a chordates and is called as hepatic portal system. This system carries blood from intestine to the liver before it is delivered to the systemic circulation. Significance of hepatic portal system in circulatory system (i) Blood that comes from alimentary canal contain glucose. amino acids and other nutrients. The liver absorbs excess of fats and glucose to be used at the time of starvation when blood passess through given. Harmful nitrogenous wastes like ammonia is converted into urea which is later removed by kidney Liver produces proteins which are transproted through blood circulation fibrinogen for blood clotting . |

Assertion : Atria act as primer pumps that increase the ventricular pumping Reason : About 80 precent of the blood flows directly through the atria into ventricles.A. If both assertion and reason are true and reason is the correct explanation of assertionB. If both assertion and reason are true but reason is not the correct explanation of assertionC. If assertion is true but reason is falseD. If both assertion and reason are false |
|
Answer» Correct Answer - A Blood normally flows continually from the great veins into the aria , about `80` percent of the blood flows directly through the atria into the ventricles even before the atria contract. Then atrial contraction usually causes an additional `20` percent filling of the ventricles. Therefore, the atria simply function as primer pumps that incerase the vertricular pumping effectiveness as much as `20` percent. |

Hepatic portal system starts fromA. Digestive system to liverB. Kidney to liverC. Liver to heartD. Liver to kidney |
|
Answer» Correct Answer - A A vein which does not carry blood directly to the heart but carries blood to another organ is called portal vein. The flow of deoxygenated blood from the digestive tract to the liver before returning to the heart is called hepatic portal circulation. Glucose is carried from digestive track to liver by hepatic portal vein. Blood leaves the liver through the hepatic vein. |
