c) The amount of blood ejected from left atrium
d) The amount of blood ejected from right atrium

5. Which of the following is the correct statement regarding capillaries (blood vessels)?
a) Smallest and thinnest blood vessels in the body for nutrient and gas exchange between the blood and surrounding tissues      
b) Small veins that collects deoxygenated blood and waste products from the tissues
c) Small arteries that regulate blow flow and control blood pressure
d) Thick blood vessels that carry oxygenated blood away from the heart and distribute it to the various organs and tissues of the body

6. Which of the following hormones regulates blood pressure?
a) Insulin 
b) Thyroxine 
c) Adrenaline      
d) Estrogen

7. What is the normal blood pressure range value for an adult healthy individual?
a) 100/60 to 110/70 mmHg
b) 110/70 to 120/80 mmHg
b) 130/80 to 140/90 mmHg
c) 140/90 to 145/95 mmHg


Answers:
1. a) Left atrium
2. c) Veins
3. d) Carrying oxygen  
4. b) The amount of blood ejected from left ventricle  
5. a) Smallest and thinnest blood vessels in the body for nutrient and gas exchange between the blood and surrounding tissues
