Q

Serous Pericardium

A

Thin, wet, double layered. Contains Visceral layer(aka, outer layer of epicardium & composed of fibroelastic tissue) & Parietal layer(inner surface of fibrous pericardium)

Q

Pectinate Muscles

A

ridges of muscles in walls of right atrium and both auricles

17
Q

Tricuspid Valve

A

3 flaps on valve. Closes when ventricle contracts

18
Q

Left Atrium

A

entrance of pulmonary veins. Contains bicuspid valve

19
Q

Bicuspid (Mitral) Valve

A

2 flaps. Valve between left atrium & left ventricle

20
Q

Right Ventricle

A

`Forces blood into pulmonary trunk. Low in oxygen. Contains Pulmonary semilunar valve, papillary muscles, chordar tendineae, & trabeculae carneae

21
Q

Pulmonary Trunk

A

Branches into right and left pulmonary artieries

22
Q

Pulmonary Semilunar Valve

A

pressure cause the opening and closing. Blood flows through here

23
Q

Papillary Muscles

A

Contracts at same time as right ventricle

24
Q

Chordae Tendineae

A

prevents prolapse of valve. Contracts same time as ventricle does so that it stays shut

25
Q

Trabeculae Carneae

A

ridges of muscles in both ventricles

26
Q

Left Ventricle

A

forces blood through aortic semilunar valve into the aorta. high in oxygen

27
Q

Pulmonary Circulation

A

Blood pressure is 30/10

28
Q

Systemic Circulation

A

Blood pressure is 120/80
