Revision from Textbook (Cv System) Flashcards
What is the pulmonary circuit?
Blood vessels that carry blood to and from lungs.
Which side of the heart receives oxygen poor blood?
Right side.
What is the systemic circuit?
Blood vessels that carry blood to and from all body tissues.
Which side of the heart receives oxygenated blood returning from the lungs?
Left side.
What are the two receiving chambers?
Right and left atrium.
What does the right atrium receive.
Blood returning from systemic
What does the left atrium receive?
Blood returning from pulmonary circuit.
What are the two pumping chambers?
Right and left ventricle.
What does the right ventricle pump?
Pumps blood to pulmonary circuit.
What does the left ventricle pump?
Blood into the systemic circuit.
How many lobes does left lung have?
2
How many lobes does right lung have?
3
What are the layers of the pericardium?
Fibrous and serous
What are the 2 layers of the serous pericardium?
Parietal and visceral.
What is the pericardial cavity?
Between parietal and visceral layer, filled with serous fluid (no friction)
What is the visceral layer of serous pericardium known as?
Epicardium.
What is the endocardium made up of?
Sheet of endothelium, continuous with endothelial lining of blood vessels leaving and entering heart.
What is the interatrial septum?
Divides the heart longitudinally (separates the atria).
What is the interventricular septum?
Divides heart longitudinally to separate ventricles.
What is the coronary sulcus?
Groove encircling junction of atria and ventricles like crown.
Where is the anterior interventricular sulcus?
Cradles anterior interventricular artery, marks anterior part of septum separating ventricles.
What are the 2 basic parts of the right atrium internally?
Smooth walled posterior, anterior portion of pectinate muscles.
What are pectinate muscles?
Bundles of muscle tissues forming ridges in the walls of heart.
What is the crista terminalis?
C shaped ridge that separates the posterior and anterior regions of the right atrium.
