Anatomy & Physiology II Lab 2: Body Cavities & Heart Anatomy
Pleural cavity:
Part of the thoracic cavity; contains each lung.
Thoracic cavity:
The chest; contains the trachea, bronchi, lungs, esophagus, mediastinum, heart and large (great) blood vessels, thymus gland and nerve, as well as the smaller pleural and pericardial cavities.
Abdominopelvic cavity:
The portion of the ventral cavity that is below the diaphragm. Can be thought of as an imaginary line running across the hipbones and dividing the body into the abdominal and pelvic cavities.
The heart lies in the _____ cavity.
pericardial
Blood is pumped out of the heart by the...
ventricles
Pelvic cavity:
Contains the end of the large intestine, rectum, urinary bladder, and reproductive organs.
Abdominal cavity:
Contains the stomach, liver, gallbladder, pancreas, spleen, small intestines, and most of the large intestine.
Pericardial cavity:
Part of the thoracic cavity; contains the heart. The pericardial cavity is flanked by the pleural cavities.
Mediastinum:
a space between the pleural cavities containing the heart, thymus, esophagus, and trachea. The heart is located in the more inferior portion of the mediastinum.
Atrioventricular (AV) valves...
allow flow into the ventricle
Semilunar (SL) valves...
allow flow out of the ventricle
Anatomically, the inferior portion of the heart is also known as the ________.
apex
Blood comes into the heart through the...
atria
Arteries carry blood ______ the heart
away from
vein
blue (most of time), takes blood towards the heart
the left side of the heart pumps blood to the ____
body
Visceral layers
cover the internal organ
parietal layer
covers the body wall/organ
The right side of the heart handles...

muscular tissue
The left side of the heart handles...

red represents
