|
Right and left atria |
Recieving chambers of heart. Singular= atrium |
|
|
|
Right and left ventricles |
Pumping chambers of the heart |
Ventriicel |
|
|
Interatrial septum |
Internal partition that separates ventricles. |
|
|
|
Interventricular septum |
Internal partition of the heart that separates the atria |
|
|
|
Pulmonary |
ریوی Pulmonary circuit vs. Systemic circuit |
Polmenery |
|
|
Pericardium |
A double-walled sac that the heart is enclosed in. Fibrous (superfacial) and serous (deep) Serous-> perietal layer- pericardial cavity- visceral (epicardium) layer |
|
|
|
The heart wall layers |
Epicardium Mysocardium Endocardium |
|
|
|
Cardiac skeleton |
1. Anchores the cardiac muscle fibers 2. Provide addition support to prevent stretch of vessels and valves 3. Not electrically excitable-> limits the spread of action potential |
|
|
|
Coronary sulcus (atrioventricular groove) |
A groove on the surface of the heart that encircles the junction of the atria and ventricles. |
Solces |
|
|
Anterior interventricular sulcus |
Cradling the anterior interventricular artery, marks the anterior position of the septum separating the right and left ventricles. |
|
|
|
Posterior interventricular sulcus |
Marks the posterior position of the septum separating the right and left ventricles. |
|
|
|
Auricles |
Small, wrinkled, protruding appendages of atrial, which increase their volume. |
Orikel |
|
|
Right atrium parts |
1. Smoth-walled posterior part 2. C-shaped ridge called crista terminalis 3. Anterior part with pectinate muscles |
|
|
|
Pectinate muscles |
Bundles of muscle tissue forming ridges in the wall of atria |
|
|
|
Left atrium parts |
Mostly smoth with pectinate muscles found only in the auricle. |
|
|
|
Fossa ovalis |
A shallow depression on the interatrial septum that marks the spot where an opening, the formen ovale, existed in the fetal heart. |
|
|
|
Superior vena cava |
Returns blood to the right atrium from body regions superior to the diagram. |
|
|
|
Inferior vena cava |
Returns blood to the right atrium from body areas below the diagram. |
|
|
|
Coronary sinus |
Collect blood draining from the myocardium to the right atrium. |
|
|
|
Pulmonary veins |
4 veins that transport blood from the lungs back to the heart (left atrium). |
|
|
|
Trabeculae carneae |
Irregular ridges of muscle that mark the internal walls of the ventricular chambers. |
Trabekule karnie |
|
|
Papillary muscles |
Play role in valve function and project into the ventricular cavity. |
