Heya mate!!! here are all your awesome answers:
14)The pulse rate is a measurement of the heart rate or the number of times the heart beats per minute.
15) The red colour to the red blood cells is due to the presence of Hemoglobin.
16) Platelets are tiny blood cells that help your body form clots to stop bleeding. If one of your blood vessels gets damaged, it sends out signals to the platelets. The platelets then rush to the site of damage and form a plug (clot) to fix the damage.
17) The process of removal of the toxic waste products produced due to cellular activities is called excretion. The parts of the body of organisms involved in the process of excretion are called excretory system.
18) The major excretory product in humans is urea. it contains water and salts.
