Where is the apex of the heart located relative to its orientation?
Directed towards the left side
Which part of the heart is less muscular but still plays a crucial role in blood circulation?
Atria
What is the purpose of the thin ligaments in the heart's valves?
To prevent backflow of blood during contractions
In pulmonary circulation, where is blood sent to be oxygenated?

What condition is characterized by persistently high blood pressure that poses significant risks like strokes?
Hypertension
What happens during a heart attack (Myocardial Infarction) due to an obstruction in coronary arteries?
Cardiac muscle death due to oxygen deprivation
What is a possible consequence of an acute blockage in coronary arteries?
"Heart muscle death due to lack of oxygen

What is the main function of pericardial fluid in the heart?
To minimize friction and facilitate the heart's movement
Which part of the heart is characterized by being less muscular compared to other components?
Atria
Where are heart valves primarily located within the heart's structure?
Between each atrium and its corresponding ventricle
What is the role of cardiac walls in the heart's function?
To contract and pump blood efficiently
How is the position of the heart primarily stabilized within the body?
Via large blood vessels entering and exiting the heart
What is the significance of the endocardium in relation to the heart's chambers?
It lines the interior of the heart's chambers smoothly
Where are major blood vessels attached to the heart in its external structure, aiding in its stabilization?
To enter and exit its broader side
What is the purpose of stents in treating cardiovascular diseases?
To improve blood circulation through the coronary arteries
How does hypertension differ from hypotension?
Hypertension leads to dizziness and fainting, while hypotension poses risks such as strokes and aneurysms.

To regulate the heart's rhythm
Why is it essential for valves to prevent backflow during heart contractions?
To maintain a unidirectional blood flow for efficient circulation
What is the potential consequence of an untreated myocardial infarction?
Damaged cardiac muscle leading to heart failure
How do ligaments contribute to the functionality of heart valves?
By supporting the valves and ensuring proper closure to prevent backflow
In what way do bypass surgeries benefit individuals with severe cardiovascular conditions?
By opening up blocked or narrowed coronary arteries through new pathways
