Mar 6, 2021 · One of the first things you will notice if you look at the 12 steps is the pattern between the right and left side of the heart is similar. Step 1 and 6 involve a blood vessel, which makes sense as this is how blood enters and exits that side of the heart. Steps 2-5 involve a chamber, valve, chamber, and valve.
Oct 1, 2020 · The cardiac cycle has 2 phases, systole and diastole, defined by depolarization and contraction vs repolarization and relaxation. This step-by-step diagram provides easy notes and explanations of the cardiac cycle, blood flow through the heart in order, and the atrial and ventricular anatomy of the heart. Learn the conduction system including ...

The heart is a composed of two pumps and two pipes. The closed-circuit design of the heart means that no variable is independent from the others. Whenever a variable, such as cardiac output (CO), is altered, it will affect the other variables. This is an important concept to understand as you continue through the units of this subchapter.
The heart is composed of two pumps and pipes. The two pumps that comprise the heart are the left heart and the right heart. These pumps present functionally different purposes. The left heart is responsible for pumping blood from the left ventricle and directing the flow to the tissues, otherwise referred to as systemic circulation. The right heart...
Pathway of Blood Flow
Now that you understand how the heart and the circulatory system are organized, we can examine the pathway of blood in closer detail. Blood flows from the right atrium to the right ventricle, where it is pumped into the pulmonary circuit. The blood in the pulmonary artery branches is low in O2 but relatively high in CO2. Gas exchange occurs in the pulmonary capillaries (O2 into the blood, CO2 out), and blood high in O2 and low in CO2 is returned to the left atrium. From here, blood enters the...
Valves of the Heart
The heart’s anatomical structure includes the presence of four valves that function to promote proper blood flow through the organ. Two of the four valves are referred to as atrioventricular valves, including the tricuspid valve located between the right atria and ventricle and the mitral valve located between the left atria and ventricle. The other two valves include; the pulmonary valve located between the right ventricle and the pulmonary arteries and the aortic valve located between the l...
The questions below can be used to assess your knowledge within this chapter. There are five multiple-choice questions that you should attempt without referring to your notes. The questions will provide you with responses to your answers to guide your studying but should not be used as your only resource.
Feb 24, 2023 · Figure Figure 20.2.1 20.2. 1: Cardiovascular Circulation The pulmonary circuit moves blood from the right side of the heart to the lungs and back to the heart. The systemic circuit moves blood from the left side of the heart to the head and body and returns it to the right side of the heart to repeat the cycle.
Feb 24, 2021 · Function and anatomy of the heart made easy using labeled diagrams of cardiac structures and blood flow through the atria, ventricles, valves, aorta, pulmonary arteries veins, superior inferior vena cava, and chambers. Includes an exercise, review worksheet, quiz, and model drawing of an anterior view (frontal section) of the heart in order to ...
And the same thing happens on this side. Let's imagine you have some backwards flow of blood by accident, meaning that it's going in the wrong direction. Well, then these valves are going to close down. So the white arrows represent the correct flow of blood, and the black arrows represent the incorrect flow of blood.
