What are the three major part of your circulatory system?

Very simply put the venous system, the arterial system and your heart. The venous system bring blood from your organs and extremities to your heart, which pumps it and the arterial system takes it from your heart to your organs and extremities.


What is the human venous systems in a diagram?

The human venous system is a network of veins that carries deoxygenated blood back to the heart. In a diagram, it typically includes major veins such as the superior and inferior vena cavae, which drain blood from the upper and lower body, respectively, as well as the pulmonary veins that return oxygenated blood from the lungs. The diagram may also illustrate deep and superficial veins, as well as the venous valves that prevent backflow. Overall, it highlights the intricate pathways through which blood circulates within the body.


What does Major intracranial arteries and branches as well as major dural venous sinuses are patent mean?

"Patent" in this context means that the major intracranial arteries, their branches, and the major dural venous sinuses are open and unobstructed, allowing for normal blood flow. This is important for maintaining adequate cerebral circulation and ensuring that the brain receives sufficient oxygen and nutrients. An absence of blockages or abnormalities in these vessels suggests a healthy vascular system within the skull.


What Two major factors affecting blood flow rates?

They include the radius of the blood vessel, the length of the system, and the viscosity of the blood.


What precautions are needed for venous access?

There are no major precautions for access during emergency procedures.


What is a determinate of left ventricular preload?

Blood volume and pulmonary vein pressures, along with venous tone and rate or return are the major determinants of LV preload (or, clinically speaking, LV end-diastolic pressure, or LVEDP).

What is the purpose of elastic stockings?

One of the reasons that elastic stocking are worn is to help the venous half of the circulatory system to move blood back to the heart. It is slower moving in the legs and has a lower blood pressure. The stockings help to keep blood moving and prevent clots in the veins. These clots can travel and cause major problems in the heart and lungs.


Why use trendelenburg position for anaphylactic shock?

The Trendelenburg position is used for patients in shock to increase blood flow, by gravity, from the major vessels in the lower extremities to the brain to help increase the blood pressure enough to keep the patient stable until advanced medical care is available.


Blood has traveled from the heart to the toes. What describes the next step of the circulation process?

After blood travels from the heart to the toes, it returns to the heart through the venous system. Deoxygenated blood from the toes enters the small veins, which converge into larger veins, ultimately leading to the inferior vena cava. This major vein carries the blood back to the right atrium of the heart, where it will be pumped to the lungs for oxygenation.


What are the major parts of our circulatory system aside from heart?

You have the aorta, large and small arteries, capillaries and veins in the systemic circulation. You have the pulmonary aorta, arteries, capillaries and veins in the venous system. The blood pressure in the systemic circulation is much greater and hence the vessels are thicker there.
