systemic route differs from the other route. In the systemic route blood is moved through the body providing it with oxygen and nutrients while blood with no oxygen is sent back to the heart. When the pulmonary enters the left to part of the heart called the atrium oxygen goes through the pulmonary veins. After it leaves the left atrium and goes to the ventricle through a valve that is called the martial

as hick as the wall of the right ventricle. The valves were ‘flaps’ attached by ‘strings’ to the heart muscle. When a finger was poked through the atria you could see it coming through the left ventricle. When a finger was poked through the pulmonary artery we saw the finger tip poked through right ventricle. Interpretation of Results: The atria looked like ‘flaps’ because there was on blood flow because the heart had been removed. The septum was diagonal not straight up and down because the

attached to the heart‚ and what does it do? The largest vessel that is attached to the heart is the aorta. This carries nutrient filled blood to the rest of the body. 3. What is pulmonary circulation? Pulmonary circulation is the circulation of blood from the heart to the lungs through the pulmonary artery and pulmonary veins. The heart pumps deoxygenated blood from the heart to the lungs and then the blood is sent back being oxygenated‚ where it is then pumped to the rest of the body. 4

is most appropriate for the nurse to monitor to determine the effectiveness of medications given to a patient to reduce left ventricular afterload? a. Mean arterial pressure (MAP) b. Systemic vascular resistance (SVR) c. Pulmonary vascular resistance (PVR) d. Pulmonary artery wedge pressure (PAWP) ANS: B Systemic vascular resistance reflects the resistance to ventricular ejection‚ or afterload. The other parameters will be monitored‚ but do not reflect afterload as directly. DIF: Cognitive Level:

tricuspid atrioventricular valves these separate the atria from the ventricles. The right atrium receives blood from the body through the superior vena cava and inferior vena cava. The left atrium receives oxygenated blood from lungs through four pulmonary veins that enter the left atrium. At the end of diastole‚ both atria contract‚ which drives an additional amount of blood into the ventricles. Systole signifies the time during which the left

hollow muscular pump that stands at the operational center of the system that pumps liquid blood throughout the body through three types of flexible tubes‚ the blood vessels (Fig. 4.1). The arteries channel blood from the heart to all parts of the body needing service. Once there‚ the blood passes through narrow arteries and enters the capillaries‚ which are the narrowest blood vessels. Many substances and some blood cells pass into and out of the blood by moving through the thin porous capillary walls

Pulmonary circulation: Pulmonary circulation transports deoxygenated blood from the right side of the heart to the lungs where the blood picks up oxygen and returns to the left side of the heart.

The arteries job is to transport blood away from the heart‚ usually only transporting highly oxygenated blood‚ having just left the lungs and on its way to the body’s tissues Arterioles • There are smaller branches of the arteries called arterioles‚ they connect to the capillaries. • Arterioles are the main
