18
Q

Where is the Atrioventricular valve found?

A

Between the atria and ventricles

19
Q

Where is the Semilunar valve found?

A

Between ventricles and either pulmonary trunk or aorta

20
Q

What happens in the Pulmonary Circuit?

A

Blood goes from the right side of the heart to lungs, where it gets oxygenated, and goes back to the left side of the heart

21
Q

What happens in the Systematic Circuit?

A

Takes blood from the left side of the heart out to body tissues, and then back to the right side of the heart

22
Q

The heart is located in the

A

Thoracic cavity

23
Q

How is the left lung since the heart is found more on the left side?

A

It is a bit smaller than the right in order to make room for the heart

24
Q

The oral cavity is linked by a

A

Mucus membrane

25
Q

All body membranes open to the exterior are all

A

Lined by a mucus membrane

26
Q

Closed body cavities are lined by

A

Serous membranes

27
Q

Heart is surrounded by

A

A double-layered membrane called the visceral pericardium

28
Q

Pericardial cavity has serous fluid, which allows for

A

Membranes to easily slide past one another

29
Q

What are the layers of the heart wall?

A
  • Epicardium
  • Myocardium
  • Endocardium
30
Q

What is the epicardium?

A

Visceral layer of pericardium

31
Q

What is the Myocardium?

A

Cardiac muscle cells

32
Q

What causes for the heart to beat?

A

The contraction of the myocardium

33
Q

What lines the heart chamber?

A

Endocardium

34
Q

What are the two chambers in the heart?

A
  • Atria

- Ventricles

35
Q

What is the function of the atria?

A

They receive blood

36
Q

What is the function of the ventricles?

A

They push out blood into the Aorta and Pulmonary Trunk

37
Q

What is the function of the Right atrium?

A

It receives O2 poor blood from systemic circuit from inferior and superior vena cava

38
Q

What is the function of the Left atrium?

A

It receives O2 rich blood from the pulmonary veins

39
Q

What blood comes into the right ventricle?

A

Right atrium blood

40
Q

What blood comes into the left ventricle?

A

Left atrium blood

41
Q

Which ventricle is thicker?

A

The left

42
Q

What prevents the mixing of blood?

A

Septum

43
Q

Right AV valve is known as

A

Tricuspid

44
Q

Left AV valve is known as

A

Bicuspid
