Document Summary
Nse 13b- assessment of healthy individual: week 3 objectives. Jarvis chapter 20: self-review anatomy and physiology. Consists of the heart, a muscular pump, and the blood vessels. Blood vessels are arranged in 2 continuous loops: the pulmonary circulation, and the systemic circulation. When the heart contracts, it pumps blood simultaneously into both loops. The precordium is the area on the anterior chest overlying the heart and great vessels. The great vessels are the major arteries and veins connected to the heart. The heart and great vessels are located between the lungs in the middle third of the thoracic cage ; this area is called the mediastinum. The superior and inferior venae cavae return unoxygenated venous blood to the right side of the heart. The fetal heart functions early; begins to beat at the end of 3 weeks gestation. Lungs are non-functional, but the fetal circulation compensates for this. Inflation and aeration of the lungs at birth produces circulatory changes.
