Heart and Pericardium components: (4)
1. Diaphragm
2. Intercostals
4. Pericardium
What does the Diaphragm look like?
it is dome shaped with a central tendon in the middle.
the shape of the Diaphragm in relaxation:
dome shaped
Regarding the thoracic cavity, in contraction, the diaphragm is ________ to... and to...
to increase thoracic cavity volume
to decrease thoracic cavity pressure
In regards to the abdominal cavity, the Disphragm contaction is flat because it...
decreases abdominal cavity volume and increases abdominal cavity pressure.
Diaphragm INN:
C3, 4, 5 Phrenic nn.
Intercostals play role in creating...
...a ridged wall for negative pressure inside thorax.
Contracting the abdominals can force the _______ _______ against the ______ _______ to force air out.
abdominal viscera
abdominal diaphragm
Pericardium is:
a Serous Membrance around the heart. (similar to lungs)
The Lungs only have 2 Layers but the Heart has how many? Name them.
3 layers:
Epicardium - outer protective layer of the heart.
Myocardium - muscular middle layer wall of the heart.
Endocardium - inner layer of the heart that is continuous with the inner lining of blood vessels.
The 1st level pericardium includes: (2)
1. Visceral Pericardium
2. Parietal Pericardium
The 2nd level pericardium includes the __________ cavity.
The Pericardial Cavity is between:
the Visceral and Parietal layers
The 3rd layer pericardium includes: (1)
Fibrous Pericardium
The Fibrous Pericardium is:
a very tough connective tissue.
The Fibrous pericardium's job is to:
anchor the heart to the sternum anteriorly and the diaphragm inferiorly.
Veins are:
any vessel that takes blood TO the heart.
Arteries are:
any vessel that takes blood AWAY from heart.
the Subclavian vv. (left and right) return blood from...
the upper limbs.

aka. Internal Thoracic aa. in thorax outer wall.
Internal Jugular v.
returns blood from head
where is the brachiocephalic vein?
where subclavian vv. joins with Internal Jugular v.
Superior Vena Cava (left and right) empties into:
the right atrium
Right Atrium
receives blood from rest of body
the Inferior Vena Cava returns blood from...
...the lower limbs and abdomen
what is the Auricle?
pouch inside the L and R atrium
Right Venticle:
bloog passes through the Rights Atrioventricular (AV) Valve entering the RIght Atrium
Right Atrioventricular has 3 cusps also known as:
Papillary mm contracts to:
keep the blood from flowing back into the Right Atrium from the Right Ventricle
ChoradeTendineae ("heart strings") are the:
connection between the Papillary mm and the Valves
Pulmonary Trunk exits the:
Right Ventricle
The Pulmonary trunk looks like:
valves in veins of our limbs
Pulmonary Semilunar Valve is:
the gateway into the Pulmonary Trunk
There are how many Pulmonry Semilunar Valves?
3 of these
Pulmonary Arteries go to:
L and R lungs for Oxygenation
Pulmonary Veins empty into:
the Left Atrium
The Pulmonary Veins contains:
oxygen rich blood which goes back to the heart from lungs
the Left Atrium receives...
...receives oxygen rich blood from the Pulmonary Veins
Left Ventricle
has thick wall (unlike the right ventricle) because blood must be pumped to the rest of the body.

side note: this is also why the heart sits mostly on the left side.
Left Atrioventricular (AV) Valve is also known as:
Bicuspus Valve
The Left Atrioventricular AV Valve had how many cusps?
2 valve cusps. This is the only difference from the the Right AV Valve.
Left AV Valve - Papillary mm. and ______ Tendineae can fail in old people and blood can flow backwards.
Aorta has how many components?
The Aorta components are:(3)
1. Ascending
2. Arch (has sub parts)
3. Decending
The Arch (of the Aorta) consist of 3 parts.
1. The Brachiocephalic Trunk (17)
2. L Common Carotid (20)
3. L Subclavian (21)
The Brachiocephalic Trunk has 2 parts:
1. R Common Carotid (18) - Goes to head
2. R Subclavian (19) goes to R Upper limb
The R Common Carotid goes to
the head
The R Subclavian goes to
the R Upper Limb
Aortic Semilunar Valve is identical to:
Pulmonart Semilunar Valve
The Aortic Semilunar Valve takes blood to:
the Aorta
