1. right atrium 2. right ventricle 3. lungs 4, left atrium 5. left ventricle

What is the systolic pressure of patient, whose blood pressure was recorded as 116/79?

116 mm Hg

A patient has a diastolic blood pressure of 75, and a systolic blood pressure of 120. How is the overall blood pressure recorded?

120/75

In the systemic circuit, freshly oxygenated blood from the __________ ventricle is pushed into the aorta to travel out to the body and then to return via veins to the ___________ atrium.

Blank 1: left Blank 2: right

The ____________________ valve is located at the opening between the left atrium and the left ventricle and the __________________ valve is located at the exit from the left ventricle.

Blank 1: mitral, bicuspid, or left atrioventricular Blank 2: aortic or aortic semilunar

Blood from the right ventricle flows to the _________ _________, which then splits into two arteries (left and right) that lead into the lungs.

Blank 1: pulmonary Blank 2: trunk

What is the skeleton of the heart?

Fibrous tissue that gives the heart its shape and anchors the myofibers.

What is the function of the coronary arteries?

Supply oxygenated blood to the heart muscle

Why does the body need skeletal muscle contraction, pressure changes during breathing, and vasoconstriction to move blood through the veins?

The blood pressure in the veins is too low to push blood toward the heart.

Blood pressure can be determined by ______.

multiplying cardiac output by peripheral resistance

When the right ventricle contracts, blood is pushed through the _______________ valve into the pulmonary trunk.

pulmonary

Blood leaving the right ventricle flows into the ______.

pulmonary trunk

Which two names are used to refer to the AV valve that separates the left atrium from the left ventricle?

pulmonary valve

Which valve is found between the right ventricle and the pulmonary trunk?

pulmonary valve

Where does the blood that enters the left atrium come from?

pulmonary veins

The tricuspid valve separates the ______________ atrium and ventricle, while the bicuspid valve separates the ________________ atrium and ventricle.

right left

What chamber of the heart pumps blood into the pulmonary trunk?

right ventricle

What factors contribute to venous return to the heart?

skeletal muscle contractions pressure changes during breathing vein vasoconstriction

Blood pressure is commonly measured using a ______.
