Q

What is the role of the left atrium?

A
  • Receives oxygen-rich blood from the lungs
  • Pumps it into the left ventricle and out to the body

Q

What does regurgitation of a valve mean?

A

The valve does not fully close allowing blood to flow back. This is called a leaky valve.

Q

What does stenosis of a valve mean?

A

The valve opening is narrowed and doesn’t allow the valve to open correctly. It is harder to pump blood and requires more force.

Q

What is the function of the endocardium?

A

The innermost layer of tissue that lines the chamber of the heart and covers the valves. Provides last line of protection from friction and trauma.

Q

What is the function of the myocardium?

A

The middle layer of the heart which is thickest and most muscular. It is composed of cardiac muscle cells which allow the heart to contract.

17
Q

Where is the myocardium most thickest and why?

A

It is most thickest around the left ventricle, as it requires substantial pressure to pump blood into the aorta and throughout the circulatory system.

18
Q

What is the function of the epicardium?

A

Thin layer of connective tissue and fat that serves as another layer of protection from trauma and friction.

19
Q

What is the function of the pericardium? and what is it also known as?

A
  • It has two layers that surround your heart.
  • It protects your heart from stretching or overfilling.
  • Lubricates the heart to prevent friction during each beat.
  • It is also known as the pericardial sac.
20
Q

What are the two layers of the pericardium? One layer is further divided into two, what are these layers called?

A

It has a serous and fibrous layer.

Serous is further divided into visceral and parietal.

Pericardial cavity is the space formed between the two layers of the serous percardium layer.

21
Q

What is the function of the fibrous and serous layers of the pericardium?

A

Fibrous - outter layer, made of thick connective tissue and is attached to the diaphragm to anchor it.

Serous - inner layer, further divided into visceral and parietal layers which is called the pericardial sac and is filled with percardial fluid to prevent friction between each beat.

22
Q

What is the acroynym to remember the layers of the Pericardium? Is this acronym from inner/outter most of the layer?

A

Fart Police Smell Villains. It is from outter to inner.

  1. Fibrous layer of the pericardium
  2. Parietal layer of serous percardium
  3. Serous fluid
  4. Visceral layer of the serous pericardium (Epicardium)
23
Q

What is this and what is it’s function?

A

The inter ventricular septum.

24
Q

What are the two atrioventricular valves and what is their purpose?

A
25
Q

What are the two semilunar valves and what is their purpose?

A
26
Q

What is the Chordae Tendineae?

A

String like tendinous bands found within both ventricles of the heart.

When the ventricles contract, blood attempts to regurgitate back up into the atria. The Chordae tendineae are inside the ventricles, helping the the atrioventricular valves to close under pressure.

27
Q

What is the largest artery in the body?

A
28
Q

What four sections is the aorta divided up into?

A
29
Q

What are the three major branches of the Aortic arch?

A

What are the three major branches of the Aortic arch?

30
Q

What part of the body does the Brachiocephalic trunk supply?

A

First and largest branch which splits into the right common carotid and right subclavian arteries.

It supplies the right side of the head and neck, and the right upper limb.

31
Q

What part of the body does the left common carotid artery supply?

A
32
Q

What part of the body does the left subclavian artery supply?

A
33
Q

Where are the arotic sinuses found?

A

They are found in the aorta.

Behind the left and right flaps of the aortic valve.

34
Q

What are the names for the main coronary arteries?

A
35
Q

What other arteries branch of the left coronary artery (LCA)?

A

• Left anterior descending (

36
Q

What other arteries branch of the right coronary artery (RCA)?

A
  • Right marginal artery
  • Posterior descending artery
37
Q

What part of the heart does the Right coronary artery (RCA) supply?

A
38
Q

What part of the heart does the right marginal artery supply?

A
39
Q

Which part of the heart does the left circumflex artery supply?

A
40
Q

What part of the heart does the Left anterior descending (LAD) artery supply?

A
