ALVEOLI are the very small air sacs where the exchange of oxygen and carbon dioxide takes place. CAPILLARIES are blood vessels in the walls of the alveoli. Blood passes through the capillaries, entering through your PULMONARY ARTERY and leaving via your PULMONARY VEIN.
This is because blood is pumped out of the heart at greater pressure from these chambers compared to the atria. ... This is due to the higher forces needed to pump blood through the systemic circuit (around the body) compared to the pulmonary circuit.
Examples of Nucleic Acids. Nucleic acids, best-known as DNA and RNA, are often termed "the building blocks of life." These building blocks are found in the nuclei of cells and help proteins to be built, help cells to replicate, govern heredity and the cell's chemical processes.
