Heart Flashcards
1
Q
muscular cone-shaped organ the size of a fist, located behind the sternum (breastbone) and between the lungs. The pumping action of the heart circulates blood throughout the body. The heart consists of two smaller upper chambers, the right atrium and the left atrium (pl. atria), and two larger lower chambers, the right ventricle and the left ventricle (pl. ventricles). The right atrium receives blood returning from the body through the veins and contracts to fill the right ventricle, which then pumps blood to the lungs. The left atrium receives blood from the lungs and contracts to fill the left ventricle, which then contracts to pump blood from the heart through the arteries to body tissues. The atrial septum separates the atria and the ventricular septum separates the ventricles. (Fig. 10.2)

2
Q
consist of the tricuspid and mitral valves, which lie between the right atrium and the right ventricle and the left atrium and left ventricle, respectively. Valves of the heart keep blood flowing in one direction.
A
atrioventricular valves
3
Q
pulmonary and aortic valves located between the right ventricle and the pulmonary artery and between the left ventricle and the aorta, respectively.
A
semilunar valves
4
Q
two-layer sac surrounding the heart, consisting of an external fibrous and an internal serous layer. The internal serous layer is then divided into two parts: the outer layer, called the parietal pericardium, and the inner layer, called the epicardium. Between these is the pericardial space, which contains fluid produced by the serous layer that facilitates movement of the heart.

24
Q
transport lymph from body tissues into the right and left subclavian veins, which then empty into the superior vena cava. The lymphatic vessels begin as capillaries spread throughout the body then merge into larger tubes that eventually become ducts in the chest. They provide a one-way flow for lymph, which enters through veins into the circulatory system.
A
lymphatic vessels
25
small, spherical bodies composed of lymphoid tissue. They may be singular or grouped together along the path of the lymph vessels. The nodes filter lymph to keep substances such as bacteria and other foreign agents from entering the blood. They also contain lymphocytes.
lymph nodes
26
located in the left side of the abdominal cavity between the stomach and the diaphragm. In adulthood, the spleen is the largest lymphatic organ in the body. Blood, rather than lymph, flows through the spleen. Blood is cleansed of microorganisms in the spleen. The spleen stores blood and destroys worn out red blood cells.
spleen
27
one of the primary lymphatic organs, it is located anterior to the ascending aorta and posterior to the sternum between the lungs. It plays an important role in the development of the body’s immune system, particularly from infancy to puberty. Around puberty the thymus gland shrinks so that most of the gland is connective tissue.
