Cardiovascular Physiology Introduction and Heart Chambers

The heart has 4 chambers, which include 2 atria and 2 ventricles. True or False?

The cardiovascular system consists of the heart and blood vessels. True or False?

The stroke volume is approximately 70 mL. True or False?

The left ventricle pumps blood to pulmonary circulation. True or False?

The cardiovascular system is responsible for the absorption and transport of nutrients from the gastrointestinal tract to the body tissues. True or False?

The thoracic aorta and superior vena cava are part of the vascular system. True or False?

The circulatory system is responsible for the transport of waste and by-products of cellular metabolism from body tissues to excretory organs.

The right ventricle runs the pulmonary circulation which is in series with the left ventricle that runs systemic circulation.

The heart is a solid muscular organ weighing about 300-350 g in adults.

The extremity of the left ventricle is called the BASE.

The systemic circulation is characterized by a high pressure belt with a systolic blood pressure (SBP) of 120 mmHg and a diastolic blood pressure (DBP) of 80 mmHg.

The heart provides the propulsive force as a pump for both pulmonary and systemic circulations.

The heart is divided into 4 chambers: 2 atria and 2 ventricles which lie side-by-side in parallel.

There are 2 semilunar valves at the exits of the aorta on the right and pulmonary trunk on the left.

The right atrium receives deoxygenated blood from the superior (SVC) and inferior (IVC) vena cavae, and pumps it to the pulmonary capillaries surrounding the alveoli.

The left atrium receives oxygenated blood and pumps it to the systemic circulation via large arteries, arterioles, and systemic capillaries to body tissues.
