Pulmonary Circulation: Anatomy and Peculiarities | Humans | Biology

Anatomy of Circulation: Blood enters lungs through two sources; pulmonary artery and bronchial arteries. The cross-sectional area of the pulmonary artery is same as that of the aorta, but it is more elastic and distensible. Through the pulmonary artery venous blood of the right ventricle goes to the lungs for oxygenation. It also carries nutrition to the pulmonary tissues. Bronchial [...]

Heart Sounds: Causes & Methods | Cardiovascular System | Humans | Biology

Introduction to Heart Sound: There are two classical sounds of heart in humans, known as the first and the second sounds (Fig. 7.56). They can be easily detected with a Stethoscope. Two other sounds have also been described - the third and the fourth - which, though diffi­cult to detect clinically, are constantly found in graphic records. The first and [...]
