Aromatherapy: Heart And Blood Circulation! Trivia Facts Quiz

1. Blood is made up of 45% solids:- (Select Three)

Red Cells (Erythrocytes)

White Cells (Leukocytes)

Platelets (Thrombocytes)

Nutrients

The correct answer is Red Cells (Erythrocytes), White Cells (Leukocytes), and Platelets (Thrombocytes). These three components are all solid elements found in the blood. Red cells, also known as erythrocytes, are responsible for carrying oxygen to the body's tissues. White cells, or leukocytes, are part of the immune system and help fight off infections. Platelets, or thrombocytes, are involved in blood clotting to prevent excessive bleeding. Nutrients, on the other hand, are not solid elements but rather dissolved substances in the blood.

2. Veins have much thinner and softer walls than arteries.

True

False

Veins have much thinner and softer walls than arteries because they are responsible for carrying deoxygenated blood back to the heart. This blood is under lower pressure compared to the oxygenated blood being pumped out by the heart through the arteries. Therefore, veins do not require thick and strong walls like arteries to withstand high pressure. The thinner and softer walls of veins allow them to expand and contract easily, facilitating the return of blood to the heart.

3. The structure of the Heart consists of several layers:- (Select Four)

Pericardium

The Epicardium

Mediastinum

Myocardium

The Endocardium

The structure of the heart consists of several layers, including the pericardium, the epicardium, the myocardium, and the endocardium. The pericardium is the outermost layer of the heart, providing protection and support. The epicardium is the thin layer that covers the surface of the heart. The myocardium is the thick, muscular middle layer responsible for pumping blood. The endocardium is the innermost layer that lines the chambers of the heart and valves. These four layers work together to ensure the proper functioning of the heart.

4. Match the following:-

These cells contain haemoglobin which carries the oxygen in the blood.

These cells are the soldiers of the body - they fight infection with their phagocytic action.

These cells are responsible for the clotting of blood - essential after injury or surgery.

Submit

5. Match the following:-

This is called a universal recipient.

This is called a universal donor.

Submit

6. Match the following:-

These are very large vessels leaving the heart, and contain oxygenated blood

These are large vessels which return deoxygenated blood to the heart.

They form a network within the tissues, and eventually join up and become venules and then veins.

Submit

7. The function of the Blood:- (Select Four)

To carry oxygen to the tissues

To discard nutrients, hormones, and vitamins.

To remove waste products, e.g. carbon dioxide, urea and excess water.

To carry antibodies.

To carry phagocytes to aid in fighting infection.

The blood carries oxygen to the tissues, allowing them to function properly. It also removes waste products such as carbon dioxide, urea, and excess water from the body. Additionally, the blood carries antibodies, which are proteins that help fight against infections. It also carries phagocytes, which are white blood cells that engulf and destroy pathogens to aid in fighting infection.

8. Thrombocytes (Platelets) - They are bigger than other cells and come from bone marrow.

True

False

Thrombocytes, also known as platelets, are actually smaller than other cells and not bigger. They are produced in the bone marrow. Therefore, the statement given is incorrect.

10. The right ventricle will pump blood to the body and the left ventricle will pump blood to the lungs, via the aorta.

True

False

The given statement is false. The right ventricle pumps blood to the lungs through the pulmonary artery, while the left ventricle pumps oxygenated blood to the body through the aorta.

Explanation

The given statement is false. The right ventricle pumps blood to the lungs through the pulmonary artery, while the left ventricle pumps oxygenated blood to the body through the aorta.
