Monocytes exit blood vessels to develop into macrophages. When monocytes migrate from the bloodstream into tissues in response to inflammation or infection, they differentiate into macrophages, which are crucial for immune responses. These macrophages play a key role in phagocytosis, tissue repair, and the orchestration of the immune response.
Pulmonary trunk
A lymph vessel. They are similar in function to blood vessels. However the lymph is moved along the vessel by muscle contractions rather than by the heart pumping.
When leaving the right ventricle during systole the blood leaves through the pulmonic semilunar valves, into the pulmonary trunk and out the right and left pulmonary arteries...heading to the lungs.
To the lungs.
When blood exits the right side of the heart it goes to the pulmonary artery and the lungs.
Arcus aortae and then further in the aorta
Oxygenated blood goes from the left ventricle into the aorta.
The valves that control the exits of the ventricles are called semilunar valves. There are two semilunar valves: the aortic valve, which regulates blood flow from the left ventricle into the aorta, and the pulmonary valve, which controls blood flow from the right ventricle into the pulmonary artery. These valves prevent backflow of blood into the ventricles after contraction.
Blood exits the heart through the 'Aorta', located just above the left Ventricle.
Exits are called exits, or way out
After blood leaves the right ventricle via the semilunar valve it exits out the pulmonary artery to the lungs where it picks up oxygen.
In the human heart, blood exits from the ventricles (left and right).
