What is the structure that surrounds the heart?
pericardium, a single-layered membrane
pleura, a double-layered sheet of tissue
pericardium, a double-layered membrane
peritoneum
What is NOT a part of the heart?
Atria
Ventricles
Septum
Alveoli
What is TRUE about the atria and ventricles?
The atria receive blood from the rest of the body
The ventricles push blood out of the heart
Atria and ventricles are separated by valves that prevent blood from flowing backward
All of the above are true
What is the CORRECT path of oxygenated blood through the heart FROM the lungs?
aorta -> left atrium -> left ventricle -> pulmonary veins -> rest of the body
pulmonary veins -> left atrium -> left ventricle -> aorta -> rest of the body
pulmonary veins -> left ventricle -> left atrium -> aorta -> rest of the body
aorta -> left ventricle -> left atrium -> pulmonary veins -> rest of the body
What is the CORRECT path of deoxygenated blood through the heart FROM the body?
pulmonary artery -> right atrium -> right ventricle -> superior/inferior vena cava -> lungs
pulmonary artery -> right ventricle -> right atrium -> superior/inferior vena cava -> lungs
superior/inferior vena cava -> right atrium -> right ventricle -> pulmonary artery -> lungs
superior/inferior vena cava -> right ventricle -> right atrium -> pulmonary artery -> lungs
What does the top number in a blood pressure measurement represent?
the pressure that your arteries experience when your ventricles contract
the pressure that your arteries experience when your ventricles are relaxed
What is NOT true about vasoconstriction?
It means the narrowing of blood vessels
It increases blood pressure
It is opposite of vasodilation
All of the above are true
How are veins adapted to help transport blood back to the heart?
By creating a high pressure gradient
Venous valves prevent blood from flowing backwards
Using gravity to help with the flow of blood
Working together with the arteries
