Total questions: 15
Worksheet time: 30mins
What is the first response of a blood vessel when it is injured?
It dilates to increase blood flow
It constricts to reduce blood flow
It releases hormones
It forms a scab
Which blood cells are primarily responsible for forming the initial plug at the site of injury?
Red blood cells
Platelets
White blood cells
Plasma cells
What is the temporary structure formed by platelets at the site of a blood vessel injury called?
Fibrin mesh
Platelet plug
Scab
Clotting factor
Which type of protein is converted into fibrin during blood clotting?
Hemoglobin
Fibrinogen
Albumin
Myosin
What is the main function of the fibrin mesh in blood clotting?
To dissolve the clot
To reinforce the platelet plug
To transport oxygen
To produce antibodies
Which group of proteins is activated in a cascade during the formation of a blood clot?
Clotting factors
Enzymes
Hormones
Antibodies
What is the final result of the blood clotting process after the vessel has healed?
Formation of a scab
Dissolution of the clot
Increase in blood flow
Production of more platelets
Which process helps to stop the initial external bleeding after a vessel is damaged?
Fibrin mesh formation
Platelet plug formation
Clot dissolution
Vasodilation
What do platelets release to attract more platelets to the site of injury?
Oxygen
Chemicals
Enzymes
Hormones
What is the role of clotting factors in blood clotting?
They break down the clot
They activate the conversion of fibrinogen to fibrin
They transport nutrients
They produce red blood cells
Which component traps more platelets and blood cells to create a stable blood clot?
Platelet plug
Fibrin mesh
Plasma
White blood cells
What happens to the blood clot after the vessel has healed?
It becomes permanent
It gradually dissolves
It turns into bone
It forms a scar
Which process is responsible for reducing blood flow immediately after vessel injury?
Vasodilation
Vasoconstriction
Clot dissolution
Platelet activation
What is the main purpose of blood clotting?
To increase blood pressure
To stop bleeding and seal wounds
To produce antibodies
To transport nutrients
Which of the following is NOT directly involved in the formation of a blood clot?
Platelets
