Left atrium
- Blood returns via the pulmonary veins to the left atrium.
Figure 20.5.2 – Pulmonary Circuit: Blood exiting from the right ventricle flows into the pulmonary trunk, which bifurcates into the two pulmonary arteries. These vessels branch to supply blood to the pulmonary capillaries, where gas exchange occurs within the lung alveoli.

Normally, each pulmonary vein connects directly with your left atrium. In that case, there are four ostia (openings) in your left atrium, one for each of your pulmonary veins. Oxygen-rich blood travels through these openings and into your left atrium.
Once gas exchange is completed, oxygenated blood flows from the pulmonary capillaries into a series of pulmonary venules that eventually lead to a series of larger pulmonary veins. Four pulmonary veins, two on the left and two on the right, return blood to the left atrium.
Oct 30, 2023 · Two pulmonary veins emerge from the hilus of each lung, and each pulmonary vein receives blood from 3-4 bronchial veins apiece before draining into the left atrium. The pulmonary veins are fixed to the pericardium travel alongside the pulmonary arteries.

- There Are Two Types of Circulation: Pulmonary Circulation and Systemic Circulation. Pulmonary circulation moves blood between the heart and the lungs.
- The Heart Powers Both Types of Circulation. The heart pumps oxygenated blood out of the left ventricle and into the aorta to begin systemic circulation.
- The Circulatory System Works in Tandem with the Respiratory System. The circulatory and respiratory systems work together to sustain the body with oxygen and to remove carbon dioxide.
- The Pulmonary Loop Only Transports Blood Between the Heart and Lungs. In the pulmonary loop, deoxygenated blood exits the right ventricle of the heart and passes through the pulmonary trunk.
Cerebral circulation is the movement of blood through the network of blood vessels supplying the brain, providing oxygen and nutrients. Learning Objectives.
