AB is universal acceptor, thus can accept all other blood group. Answer : (d)

The amount of blood put out by the left ventricle of the heart in one contraction is called the stroke volume. The stroke volume and the heart rate determine the cardiac output. Normal adult has a cardiac output of 5 L/min; assuming a heart rate of 70 beats/min. Answer : (b)

A high white blood cell count usually indicates: An increased production of white blood cells to fight an infection A reaction to a drug that increases white blood cell production A disease of bone marrow, causing abnormally high production of white blood cells An immune system disorder that increases white blood cell production Answer : (b)

The heart has four valves The mitral valve and tricuspid valve are located between the between the atria (upper heart chambers) and the ventricles (lower heart chambers). The one-way valves in deep veins prevent blood from flowing backward, Answer : (b)

Sphygmomanometerfor determination of systolic and diastolic blood pressure by increasing and gradually releasing the pressure in the cuff. Answer : (d)

Globulin: are a group of proteins in the blood stream that help to regulate the function of the circulatory system. Albumin: is the main protein of human blood plasma. It binds water, cations (such as Ca2+, Na + and K +), fatty acids Amylase: is an enzyme that helps digest carbohydrates Fibrinogen: is a glycoprotein in vertebrates that helps in the formation of blood clots Answer : (b)

Arthritis: is inflammation of one or more joints. A joint is the area where two bones meet. An aneurysm: is a localized, blood-filled balloon-like bulge in the wall of a blood vessel. can occur in any blood vessel. Arteriosclerosis: is the thickening, hardening and loss of elasticity of the walls of arteries Answer : (c)

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)

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)

Lymphoid tissue has several different structural organizations related to its particular function in the immune response. such as white blood cells (leukocytes), bone marrow, and the thymus, spleen, and lymph nodes. Tonsils are collections of lymphoid tissue facing into the aero-digestive tract. Answer : (d)

Answer : (a)

for a given amount of body mass, a small animal has a higher metabolic rate than a large animal. Since heart rate is a major factor of metabolic rate, the higher metabolic rate of small animals is manifested in a higher heart rate. Thus assertion is true and statement of reasoning is also true but reasoning is not a explanation for assertion Answer : (b)

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)

An Eosinophils is a type of white blood cell present in the blood.The level of eosinophils can be too high (known as eosinophilia) in response to allergies. They can also be too high when exposed to certain types of bacteria or parasites. Answer : (a)

Answer : (a)

Answer : (a)

Plasma constitutes 55% of blood. Major minerals, like calcium, chloride, magnesium, phosphorus, potassium, sodium and sulfur, are found in our body in amounts larger than 5 grams. Trace minerals, like chromium, copper, fluoride, iodine, iron, manganese, selenium and zinc, are found in our body in amounts less than 5 grams. 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)

Lymph has a composition comparable to that of blood plasma, but it may differ slightly. Lymph contains white blood cells. In particular, the lymph that leaves a lymph node is richer in lymphocytes., Likewise the lymph formed in the human digestive system called chyle is rich in triglycerides (fat), and looks milky white because of its lipid content. Answer : (d)

Answer : (c)

The inner layer of the pericardium, a conical sac of fibrous tissue that surrounds the heart and the roots of the great blood vessels. The pericardium is the membrane that surrounds and protects the heart Answer : (c)

The papillary muscles are muscles located in the ventricles of the heart. They attach to the cusps of the atrioventricular valves via the chordae tendineae and contract to prevent inversion or prolapse of these valves on systole. Answer : (a)

Answer : (d)

Answer : (c)

Monocytes are a type of white blood cell, or leukocyte. Answer : (b)
