Identify and describe the function of the different types of circulation pulmonary and systemic circuits?
The pulmonary circuation is the one that goes from the right ventricle throught the lungs and returns to the heart at the left atrium. The purpose of the this part of the circulation is to collect oxygen from and remove CO2 to the air at the exchange surfaces in the lungs and to provide the cells here with nutrients. The systemic circulaiton is the one that goes from the left ventricle round the body and barck to the heart at the right atrium. The puropse of this part is to deliver oxygen and nutrients to the cells of the body, to deliver chemical messages using hormones, to collect hamrfull or useless metabolites and to collect products of digestion.

What are the three major circuits of blood flow?
Pulmonary circulation (between the heart and lungs) Systematic circulation (between the heart and the rest of the body) Coronary circulation (the heart's own blood supply/supply to cardiac tissue)
What are the 2 blood circuits of the body?
The two blood circuits of the body are the systemic circulation, which carries oxygen-rich blood from the heart to the body tissues and back to the heart, and the pulmonary circulation, which carries oxygen-poor blood from the heart to the lungs for oxygenation and back to the heart.
Do the pulmonary and systemic circuits contain the same amount of blood?
No, the pulmonary circuit contains less blood than the systemic circuit. The pulmonary circuit sends deoxygenated blood from the heart to the lungs for oxygenation, while the systemic circuit delivers oxygenated blood from the heart to the rest of the body's tissues.
How many circulatory systems are in the human body?
It is one system that works together, but it is a double system. It is made up of the Pulmonary Circulatory System, which carries blood to the lungs to swap deoxygenated blood for oxygenated blood and the Systemic Circulatory System, which carries blood from the heart to the rest of the body. This is why the heart has four chambers - because it is a double system.
How is a circuit like your circulatory system?
Amphibian Circulatory Systems. In amphibians, reptiles, birds, and mammals, blood flow is directed in two circuits: one through the lungs and back to the heart (pulmonary circulation) and the other throughout the rest of the body and its organs, including the brain (systemiccirculation).
What are the three major circuits of blood flow?
Pulmonary circulation (between the heart and lungs) Systematic circulation (between the heart and the rest of the body) Coronary circulation (the heart's own blood supply/supply to cardiac tissue)
What are the 2 circulatory circuits?
systemic and pulmonary
What 2 circuits does the heart pumps blood through what?
Pulmonary and systemic
Blood vessels in the cardiovascular system are subdivided into the?
systemic and pulmonary circuits
Why do we have two cycles of blood through the heart (the pulmonary and systemic circulation?
We have two cycles of blood through the heart—pulmonary and systemic circulation—to efficiently transport oxygen and nutrients throughout the body while removing carbon dioxide and metabolic wastes. The pulmonary circulation directs deoxygenated blood from the heart to the lungs for oxygenation, while systemic circulation delivers oxygen-rich blood from the heart to the rest of the body. This separation allows for optimal gas exchange and ensures that tissues receive the oxygen they need to function effectively. Additionally, it helps maintain pressure differences that facilitate blood flow in both circuits.
What is pulmonary circuits?
The pulmonary circuit is the movement of oxygen depleted blood to the lungs to pick up oxygen and unload carbon dioxide.
What are the two paths the blood follows when it leaves the heart?
the Pulmonary and systemic are the two circuits
Compare between single loop circulation and double loop circulation?
In single loop circulation, blood flows through the heart and body in a single circuit, while in double loop circulation, blood flows through two separate circuits in the body: pulmonary circulation and systemic circulation. Single loop circulation is found in fish, while double loop circulation is found in humans and other mammals. Double loop circulation allows for separation of oxygenated and deoxygenated blood, leading to more efficient oxygen delivery to tissues.
What is the correct path blood flow through the body and lungs?
Start in the superior and inferior vena-cava, moves to the right atrium, goes through the tricuspid valve to the right ventricle. The blood then goes through the pulmonary semi-lunar valve to the pulmonary artery (which contains oxygen poor blood). This then goes to the lungs where the oxygen poor blood is oxygenated and comes back to the heart via the pulmonary vein (which contains oxygen rich blood).
What is the advantage of a double circulation system?
mammals have double circulation which means that during one circulation blood passes twice through the heart. It is necessary because double circulation is important in humans because it keeps oxygenated and deoxygenated blood separate and moreover it circulate blood to organs efficiently.
What are the 2 blood circuits of the body?
The two blood circuits of the body are the systemic circulation, which carries oxygen-rich blood from the heart to the body tissues and back to the heart, and the pulmonary circulation, which carries oxygen-poor blood from the heart to the lungs for oxygenation and back to the heart.
Why have the ventricles got thicker walls then the atria?
atria are just the receiving chambers, it is the ventricles that actually pump the blood into the pulmonary and systemic circuits
