Perfusion is the circulation of blood within an organ or tissue in adequate amounts to meet the cell's current needs.
Adequate oxygen-carrying capacity of blood depends on the presence of enough hemoglobin in red blood cells, proper functioning of the lungs to exchange oxygen and carbon dioxide, and efficient circulation of blood throughout the body to deliver oxygen to tissues. Any disruption in these factors can lead to decreased oxygen delivery to cells and tissues.
referred to as perfusion. Adequate perfusion ensures that cells receive enough oxygen and nutrients to function properly and remove waste products. Maintaining proper perfusion is essential for overall organ and tissue health.
Coronary circulation is the circulation of blood in the blood vessels of the heart muscle (the myocardium). The vessels that deliver oxygen-rich blood to the myocardium are known as coronary arteries. The vessels that remove the deoxygenated blood from the heart muscle are known as coronary veins.
Within the pulmonary circulation, deoxygenated blood is pumped from the heart to the lungs to pick up oxygen and release carbon dioxide. The oxygenated blood then travels back to the heart to be pumped to the rest of the body. The pulmonary circulation works in conjunction with the systemic circulation to ensure oxygen delivery to tissues and removal of waste products.
Systematic circulation is the circulation of blood from the heart, to the body and then back to the heart again, while pulmonary circulation is the circulation of blood from the heart, to the lungs and then back to the heart.

systemic circulation
This is called the pulmonary circulation.
circulation
The flow of blood to and from the lungs is called pulmonary circulation.
It is called the pulmonary circulation, where blood travels to the lungs to receive oxygen and lose carbon dioxide, before returning to the heart.
Respratory systen
In fetal circulation, the placenta provides oxygen and nutrients to the fetus, so the lungs are not used for oxygen exchange - instead, a bypass called the ductus arteriosus shunts blood away from the lungs. After birth, the lungs take over oxygen exchange, the ductus arteriosus closes, and the foramen ovale between the atria closes, redirecting blood flow through the heart to support pulmonary circulation.
It is called the pulmonary circulation, where blood travels to the lungs to receive oxygen and lose carbon dioxide, before returning to the heart.
The respiratory circulation is also referred to as the pulmonary circulation or the pulmonary system. It is responsible for the circulation of blood between the heart and the lungs, where carbon dioxide is exchanged for oxygen.
Cardiac muscle tissue is supplied with nutrients and oxygen by the coronary arteries, which branch off the aorta and supply blood to the heart muscle. These arteries ensure adequate delivery of oxygen and nutrients to the heart for proper function.
The movement of blood carrying food and oxygen to the cells is called circulation. This process involves blood being pumped by the heart through blood vessels to reach all parts of the body, delivering nutrients and oxygen while removing waste products.
