Q6 The function of the pulmonary artery is to transport blood
-
From the lungs to the heart
-
B. from the heart to the lungs
-
From the heart to the skeletal muscles
-
From the skeletal muscles to the heart
Correct Answer
A. B. from the heart to the lungsExplanation
The pulmonary artery is responsible for carrying deoxygenated blood from the heart to the lungs. In the lungs, the blood picks up oxygen and gets rid of carbon dioxide through the process of respiration. Once oxygenated, the blood returns to the heart through the pulmonary veins. Therefore, the correct answer is "b. from the heart to the lungs."Rate this question:

The role of heart valves is to control the
-
Two-way flow of blood through the heart
-
Electrical conductivity of the heart
-
Amount of oxygen in the heart
-
One-way flow of blood through the heart
Correct Answer
A. One-way flow of blood through the heartExplanation
Heart valves play a crucial role in ensuring the one-way flow of blood through the heart. They prevent the backflow of blood by opening and closing at the right time, allowing blood to flow in only one direction. This mechanism ensures that oxygenated blood is efficiently pumped to the rest of the body while deoxygenated blood is directed towards the lungs for oxygenation. Without the one-way flow provided by the heart valves, blood would not be able to circulate properly, leading to inefficient oxygenation and overall compromised cardiovascular function.Rate this question:

Where is the heart located?
-
Posterior to (behind) the sternum and just right of centre
-
Posterior to (behind) the sternum and just left of centre
-
Anterior to (in front of) the lungs and just left of centre
-
Anterior to (in front of) the lungs and just right of centre
Correct Answer
A. Posterior to (behind) the sternum and just left of centreExplanation
The heart is located behind the sternum, which is the bone in the center of the chest. It is slightly to the left of center, hence it is described as being just left of center. This position allows the heart to be closer to the left lung, which it works closely with to pump and oxygenate blood throughout the body.Rate this question:

Through which major blood vessel does the left ventricle pump blood
-
Aorta
-
Vena CAva
-
Pulmonary vein
-
PUlmonary artery
Correct Answer
A. AortaExplanation
The left ventricle pumps oxygenated blood out of the heart and into the systemic circulation. The aorta is the major blood vessel that carries this oxygenated blood from the left ventricle to the rest of the body. It is the largest artery in the body and branches out into smaller arteries to supply oxygen and nutrients to all the organs and tissues.Rate this question:

Where are the lungs located in relation to the diaphragm?
-
A. Above
-
Below
-
Behind
-
In front
Correct Answer
A. A. AboveExplanation
The lungs are located above the diaphragm. The diaphragm is a dome-shaped muscle that separates the chest cavity from the abdominal cavity. The lungs are situated in the chest cavity, above the diaphragm, and are protected by the ribcage.Rate this question:

According to the National Institute for Health and Care Excellence (NICE), hypertension is considered severe if
-
Systolic blood pressure is 180 mmHg or higher or diastolic blood pressure is 110 mmHg or higher
-
Systolic blood pressure is 140 mmHg or higher or diastolic blood pressure is 90 mmHg or higher
-
Systolic blood pressure is 160 mmHg or higher or diastolic blood pressure is 100 mmHg or higher
-
Systolic blood pressure is 150 mmHg or higher or diastolic blood pressure is 110 mmHg or higher
Correct Answer
A. Systolic blood pressure is 180 mmHg or higher or diastolic blood pressure is 110 mmHg or higherExplanation
According to the National Institute for Health and Care Excellence (NICE), hypertension is considered severe if the systolic blood pressure is 180 mmHg or higher or the diastolic blood pressure is 110 mmHg or higher. This means that if a person's blood pressure reaches or exceeds these levels, it is classified as severe hypertension.Rate this question:

During pulmonary circulation the
-
Left ventricle pumps de-oxygenated blood via an artery to the lungs
-
B. left ventricle pumps oxygenated blood via an artery to the lungs
-
C. right ventricle pumps de-oxygenated blood via an artery to the lungs
-
Right ventricle pumps oxygenated blood via an artery to the lungs
Correct Answer
A. C. right ventricle pumps de-oxygenated blood via an artery to the lungsExplanation
During pulmonary circulation, the right ventricle pumps de-oxygenated blood via an artery to the lungs. This is because the right ventricle receives de-oxygenated blood from the body and pumps it to the lungs for oxygenation. Once the blood reaches the lungs, it undergoes oxygenation and becomes oxygenated before returning to the heart. Therefore, option c is the correct answer.Rate this question:

Diastolic blood pressure is a measure of the force that blood exerts on the walls of the
-
Arteries whilst the heart contracts
-
Veins whilst the heart contracts
-
Arteries whilst the heart relaxes
-
Veins whilst the heart relaxes
Correct Answer
A. Arteries whilst the heart relaxesExplanation
Diastolic blood pressure is a measure of the force that blood exerts on the walls of the arteries whilst the heart relaxes. During diastole, the heart is in its resting phase and is filling with blood. The pressure exerted on the arterial walls during this phase represents the minimum pressure in the arteries, which is known as diastolic blood pressure. This measurement is important in assessing the health of the cardiovascular system and can help identify conditions such as hypertension.Rate this question:
