What are the two types of circulation ?
Pulmonary circulation and systemic circulation
What are the main components of the mammalian heart?
4 chambers: 2 atria (right and left) and 2 ventricles (right and left)
Septum separating the left and right sides
4 valves: tricuspid, bicuspid (mitral), aortic, and pulmonary
Myocardium (heart muscle)
Pericardium (double-layered sac)
How many chambers does the mammalian heart have? 
4 chambers
What is the function of the septum in the heart?
It separates the left and right sides of the heart to prevent blood mixing
What are the names of the two atria in the mammalian heart?
Right atrium and left atrium
What are the names of the two ventricles in the mammalian heart? 
Right ventricle and left ventricle
What is the role of the valves in the heart?
To stop the backflow of blood
How many valves are there in the mammalian heart? 
4 valves
What are the names of the valves located between the right atrium and right ventricle?
Tricuspid valve
What is another name for the bicuspid valve? 
Mitral valve
Where are the semilunar valves located? 
In the aorta and pulmonary artery
Which vessel brings deoxygenated blood to the heart?
Vena cava
Which vessel takes deoxygenated blood from the heart to the lungs?
Pulmonary artery
Which vessel brings oxygenated blood from the lungs to the heart?
Pulmonary vein
Which vessel takes oxygenated blood from the heart to the rest of the body?
Aorta
Summarize the direction of blood flow through the heart.
Deoxygenated blood returns to the heart via the vena cava
Blood enters the right atrium
Blood flows to the right ventricle
Blood is pumped to the lungs via the pulmonary artery
Oxygenated blood returns to the left atrium via the pulmonary vein
Blood flows to the left ventricle
Blood is distributed to the body through the aorta
Red blood cells are called erythrocytes
White blood cells - leukocytes
Platelets are called thrombocytes
