Terms in this Study Set(20)
What is the main function of the heart?
To pump blood throughout the body, delivering oxygen and nutrients.
What are the four chambers of the heart?
Right atrium, right ventricle, left atrium, left ventricle.
True or false: The right side of the heart handles oxygenated blood.
False, because it handles deoxygenated blood returning from the body.
Difference between arteries and veins?
Arteries carry blood away from the heart; veins return blood to the heart.
Fill in the blank: Blood enters the right atrium through the _____.
Superior and inferior vena cava.
What pumps blood from the right ventricle?
The pulmonary artery sends deoxygenated blood to the lungs.
What does the left atrium receive?
Oxygenated blood from the lungs via the pulmonary veins.
True or false: The left ventricle has thicker walls than the right ventricle.
True, because it needs to pump blood to the entire body.
What is the role of the mitral valve?
It prevents backflow of blood from the left ventricle to the left atrium.
What kind of blood does the aorta carry?
Oxygenated blood from the left ventricle to the body.
What is the function of the septum?
To separate the left and right sides of the heart.
Which valve prevents backflow into the right atrium?
The tricuspid valve.
What is the sinoatrial (SA) node?
The heart's natural pacemaker, initiating the heartbeat.
True or false: The pulmonary veins carry deoxygenated blood.
False, because they transport oxygenated blood to the left atrium.
Fill in the blank: Blood flows from the left ventricle into the _____.
Aorta.
What is diastole?
The phase when the heart relaxes and fills with blood.
What is systole?
The phase when the heart contracts and pumps blood out.
What are coronary arteries?
Blood vessels that supply the heart muscle with oxygenated blood.
What happens at the capillaries?
Gas and nutrient exchange occurs between blood and tissues.
Which side of the heart deals with systemic circulation?
The left side, pumping oxygenated blood to the body.
