True or False. Systolic blood pressure remains unchanged from supine to sitting

• True

• False

Which of the following is the correct flow of blood inside the heart?

• right atrium -> tricuspid valve -> right ventricle -> pulmonic valve -> pulmonary trunk -> pulmonary artery -> lungs -> pulmonary veins -> left atrium -> mitral valve valves -> left ventricle -> aortic valve -> ascending aorta

• right atrium -> mitral valve -> right ventricle -> pulmonic valve -> pulmonary trunk -> pulmonary artery -> lungs -> pulmonary veins -> left atrium -> tricuspid valve -> left ventricle -> aortic valve -> ascending aorta

• right atrium -> mitral valve -> right ventricle -> pulmonic valve -> pulmonary trunk -> pulmonary veins -> lungs -> pulmonary artery -> left atrium -> tricuspid valve -> left ventricle -> aortic valve -> ascending aorta

• right atrium -> tricuspid valve -> right ventricle -> pulmonic valve -> pulmonary trunk -> pulmonary veins -> lungs -> pulmonary artery -> left atrium -> mitral valve valves -> left ventricle -> aortic valve -> ascending aorta

It is the force of blood pushing against the blood vessel walls.

• Heart Rate

• Blood pressure

• Stroke Volume

• Pumping

True or False. Systole is the term to describe when the heart relaxes. Diastole is the term to describe when the heart contracts.

• True

• False

True or False. During systole, the pressure inside the heart increases while the volume decreases.

• True

• False

The first heart sound is heard during

• Isovolumetric relaxation

• Isovolumetric contraction

• Rapid ventricular filling

• Atrial contraction

These are abnormal sounds heard in various parts of the vascular system

• Gossips

• Murmurs

• Galloping

• Crackles

Stenosis is when the opening on the valves is too small causing resistance to ejection. Regurgitation is the backflow of blood due to improper closure of incompetent aorta.

• Both are true

• Both are false

• 1st statement true; 2nd statement false

• 1st statement false; 2nd statement true

Blood pressure and Heart rate can be regulated by the baroreceptors located at the:

• Carotid sinus

• Veins

• Capillaries

• Ventricles

Cold pressor test is used to test

• autonomic function

• pain tolerance

• both

• none
