Heart Anatomy and Blood Pressure
The cardiovascular system is an organ system that distributes nutrients and oxygen to the body’s cells. The heart is an essential organ that pumps blood throughout the body. The cardiac cycle, the pressure of the blood, and the heart rate all play into how the heart is so significant to the cardiovascular system.
This illustration depicts the left ventricle, right ventricle, tricuspid valve, the bicuspid (mitral) valve, left atrium, right atrium, superior vena cava, inferior vena cava, aorta, pulmonary arteries, pulmonary veins, the lungs, and blood cells. The arrows in figure B portray the directions that blood flows through the heart. The light blue arrow depicts the blood entering the right atrium from both the superior and interior vena cavae. The light red arrow shows the blood coming from the lungs through the pulmonary veins into the left atrium.

This device is an inflatable rubber cuff that is to be wrapped around the arm. As the heart beats, blood from the arteries causes a decrease in pressure as the heart ventricles prepare for another beat. The sphygmomanometer cuff is inflated above than the expected systolic pressure. As the valve is opened, cuff pressure slowly decreases until it equals the arterial systolic pressure. At this point, blood starts to flow past the cuff, creating blood flow and sounds that can be heard by a stethoscope. Systolic pressure refers to the amount of pressure in the arties during the contraction of the heart muscle. The pressure in the arteries when the heart rests between beats is known as the diastolic pressure. The normal blood pressure of a sixteen-year-old female includes: ninety-five to one hundred-and-five for the systolic pressure, and fifty to sixty-five for the diastolic
