Answer 1

91) Where in the circulatory system does LOW hydrostatic pressure require valves to prevent the back flow of blood?

Answer: Heart

92) Which blood vessels are leaky?

Answer: (D) Arterioles

93) Which blood vessels in the human body are most numerous and have the lowest blood velocity (speed)
Answer: (c) capillaries

Rational: capillaries are the one present in the alveoli of the lungs which is responsible for the exchange of the gas in the blood. This process will be slow while exchanging the gases.

94) Which are carrying blood away from the heart
Answer: (E) Arteries

95) Which are carrying blood to the heart
Answer: (B) veins

96) Blood pressure is reported as

Answer: (A) systolic pressure over diastolic pressure

Rational: Our normal Blood press is 120/80 mmhg , Here 120 refers to the contraction of the heart muscles and the 80 refers to the relaxation of heart muscles.

97)Which can cause thorough fare channels through capillary beds?

Answer:(c) pre capillaries sphincters

98)Pick the side of a capillary bed where blood plasma leaks out into the interstitial fluid

Answer: (c) Neither of these

Rational: Because its done by osmotic and hydrostatic pressure in the blood vessels.

99) Pick the blood component that you could expect to find in blood plasma

Answer: (D) water soluble blood proteins and inorganic ions (salts)

100.pick the correct sequence of events during blood clotting

Answer: (A)Clotting factors convert Prothrombin to Thrombin and Thrombin converts Fibrinogen to Fibrin
