Total questions: 20
Worksheet time: 11mins
1. Name the three main components in the circulatory system of humans.
Blood, lymphatic vessels, heart
Blood, Haemolymph, heart
Blood, heart, blood vessels
Tubular heart, haemolymph, haemolymph vessels
2. Which of the following is the correct statement about blood?
Consist of arteries, capillaries and veins that are connected to the heart, and transport blood to all the body tissues.
Functions as a muscular pump that circulates blood to the whole body
A type of connective tissue that is made up of blood plasma, blood cells and platelets. Blood acts as a medium of transportation
3. The heart is located between the lungs in the thorax cavity and contains four chambers namely
the atrium and ventricle.
the left atrium, right atrium, left ventricle and right ventricle.
the left atrium, right atrium and a ventricle.
What wall separates the left side and right side of the heart?
ventricle
atrium
septum
the great wall
5. What parts act like doors that control blood flow in the heart?
heart dams
valves
muscle
chambers
6. The characteristics of ventricle are:
receives blood that returns to the heart
has thicker walls and contract stronger than the atrium
The wall of the right ventricle is much thicker than the wall of the left ventricle
pumps blood out of the heart
7. Name the parts labelled by X and Y
X: coronary veins
Y: coronary arteries
X: coronary arteries
Y: coronary veins
X: renal veins
Y: renal arteries
8. Name the parts labelled by P, Q, R and S
P: vena cava Q: pulmonary artery
R: aorta S: pulmonary vein
P: vena cava Q: pulmonary vein
R: aorta S: pulmonary artery
P: aorta Q: pulmonary artery
R: vena cava S: pulmonary vein
P: pulmonary vein Q: pulmonary artery
R: aorta S: vena cava
9. Coronary arteries transport ___________ for heart tissues while coronary veins transport ____________ .
deoxygenated blood, oxygenated blood
oxygenated blood, deoxygenated blood
oxygenated blood, blood plasma
10. Which of the following are the valves that control the blood flow from atria to ventricles?
A & B
B & C
B & D
A & C
11. Which of the following is correctly match with the function of the part labelled by C?
ensures that blood which flows into the left ventricle does not flow back into the left atrium
ensures that blood which flows into the right ventricle does not flow back into the right atrium
ensures that the oxygenated blood does not mix with the deoxygenated blood
ensures that blood which flows out of the heart does not flow back into the ventricle when the ventricle relaxes.
12. The components of blood cells consist of _________, _________ and _________.

erythrocytes, blood plasma, leucocytes
erythrocytes, antibodies, leucocytes
erythrocytes, platelets, leucocytes
13. Which of the following plasma protein controls blood osmotic pressure?
albumin
globulin

The above characteristics are related to:
platelets
leucocytes
erythrocytes
plasma protein
15. Which of the following leucocytes contain granule?
basophil, monocyte, neutrophil
basophil, eosinophil, lymphocyte
basophil, eosinophil, neutrophil
monocyte, lymphocyte
16. Lymphocytes produce antibodies to destroy bacteria and viruses that enter the body. Which of the following is the characteristic of lymphocytes?
The nucleus is made up of two to five lobes
The nucleus is made up of two lobes
Contains a large nucleus with very little cytoplasm
The biggest leucocyte
17. The diagram below shows the types of human blood vessels. What is the function of Y?
transport blood at a high pressure to the tissues.
allow the exchange of gases to occur between blood and cells through diffusion.
carries deoxygenated blood back to the heart.
allow the exchange of gases to occur between blood and cells through active transport.
18.
*Wall is thin, less muscular and less elastic,
*contain valves to maintain one-way flow of blood,
*has a large lumen.
the above characteristics are related to:
arteries
capillaries
veins
19. Which of the following leucocytes are phagocytes?
monocyte & neutrophil
lymphocyte & basophil
monocyte & lymphocyte
lymphocyte & neutrophil
20. Choose the correct statements about blood capillaries.
Contain valves to maintain one-way flow of blood
The direction of blood flow is from the heart to the entire body.
