Angina

Given below are four statements (i-iv) regarding human blood circulatory system (i) Arteries are thick-walled and have narrow lumen as compared to veins (ii) Angina is acute chest pain when the blood circulation to the brain is reduced (iii) Persons with blood group AB can donate blood to any person with any blood group under ABO system (iv) Calcium ions play a very important role in blood clotting Which two of the above statements are correct ?

Give below are four statement, a-d, regarding human blood circulatory system. Find the correct one. (a) Arteries are thick-walled and have narrow lumen as compared to veins (b) Angina is acute chest pain when the blood circulation to brain is reduced (c ) Person with blood group AB can donate blood to any person with any blood group under ABO system (d) Calcium ions play a very important role in blood clotting

Match column I with column II and select the correct option from the codes given below {:(,"Column I",,"Column II"),("A.","Heart failure","(i)",underset(underset("blood supply")("damaged by an inadequate"))("Heart muscle is suddenly")),("B.","Cardiac arrest","(ii)",underset(underset("heart muscles")("inadequate" O_(2) "reachinh the"))("Chest pain due to")),("C.","Heart attack","(iii)","Atherosclerosis"),("D.",underset("diseas(CAD)")("Coronary artery"),("iv"),underset(underset("the needs of the body")("efficiency enough to meet"))("Heart not pumping blood")),("E.","Angina pectoris","(v)","Heart stops beating"):}

Read the following statements and find out the incorrect statements. a. All vertebrates and a few invertebrates have a closed circulatory system. b. Hyperension leads to heart disease and slso affects vital organs like brain and lungs. c. CAD affects the vessels that supply blood to the skeletan muscles. d. In angina, a symptom of chronic chest pain appears when no enough oxygen is reaching the heart muscle. e. Heary attack means the state of heart when it is not pumpin blood effectively enough to meet the needs of the body.

a. SAN generates as action potential which stimulates atrial systole. b. ECG is an electrical representation of the graphical activity of the heart during a cardiac cycle. c. The cardiac output of a normal man will be much lesser than an athlete. d. The wall of right ventricle is much thicker than the left ventricle e. In pisces the two separate circulatory pathways are present, hence they have double circulation. f. The clsoed circulatory pattern is considered to be more advantageous than open circulatory pattern. g. Glucose is absorbed by simple diffusion through lymph in lacteales present in the intestinal villi. h. The SAN can generate the maximum number of action potential i.e. 140-150 mi n^(-1) in neonates, and is responsible for initiation and maintenance of the rhythmic contractile activity of the heart. i. Angina can occur in any age but more common among the neonates and infants. j. heart failure is sometimes called congestive heart failure because congestion of the blood vessels is one of the main symptoms of this disease.

Given below are three statements (I -IV) regarding the human blood circulatory system . (I) In the treatment of angina pectoris nitrous oxide and nitro glycerin are used. (II) veins have thinner walls and broader lumen than arteries . (III) Artificial pacemakers are used in arrhythmia. How many of the above are correct statements ?

Correctly match column -I with column -II {:(,"Column -I",,"Column-II"),(A-,"Cardiac arrest",(ii), "Heart not pumping blood effectively"),(B-,"Heart Failure",(ii),"Heart muscle is suddenly damages"),(C-,"Heart attack",(ii),"Heart muscle is suddenly damages"),(D-,"Angina",(iii),"Heart stops beating"):}

Given below are four statements (A-D) regarding human blood circulatory system A. Arteries are thick walled and have narrow lumen as compared to veins. B. Angina is acute chest pain when the blood circulation to the brain is reduced. C. Persons with blood group-AB can donatc blood to any person with any blood group under ABO system. D. Calcium ions play a very important role in blood clotting. Which two of the above statements are correct ?
