Q

What does the left atrium take in?

A
  • 4 valve-less pulmonary veins
27
Q

What 2 orifices exist within the left ventricle?

A
  • Left atrioventricular posteriorly
  • Aortic superiorly
28
Q

What is the role of the atrioventricular valves?

A
  • Seperate atria and ventricles
28
Q

What 2 valves make up the atrioventricular valves?

A
  1. Bicuspid mital valve
  2. Tricuspid valve
29
Q

What is the difference between the mitral valve and tricuspid?

A

Mitral has 2 cusps, tricuspid has 3 cusps

30
Q

What are chordae tendineae and their role?

A
  • Thin fibres from free edge of the cusps
  • They prevent cusps from turning inside out during contractions
31
Q

What are papilliary muscles?

A
  • Connection to chordae tendineae
  • provides tension to keep cusps closed during contraction
32
Q

What are the 2 semilunar valves?

A
  • Pulmonary valve
  • Aortic valve
33
Q

What happens when the atrioventricular valves relax?

A
  • They allow blood to enter
34
Q

What are the 2 main parts of the pericardium?

A
  • Outer fibrous
  • Inner serous
35
Q

What is the role of pericardial fluid?

A
  • Lubricate heart and remove friction
