Slide 1 CVS

The cardiovascular system is divided into two circuits. What are these circuits?

• Pulmonary and respiratory circuits

• Respiratory and digestive circuits

• Pulmonary and systemic circuits

• Systemic and lymphatic circuits

Which valve separates the left atrium from the left ventricle?

• Tricuspid valve

• Mitral valve

• Pulmonary valve

• Aortic valve

In which vessels does the largest decrease in pressure occur?

• Arteries

• Arterioles

• Capillaries

• Veins

What factor primarily determines the velocity of blood flow in a vessel?

• Resistance of the vessel

• Compliance of the vessel

• Blood pressure

• Cross-sectional area

How does the resistance of blood vessels change with a decrease in blood viscosity?

• Decreases

• Increases

• Remains unchanged

• Depends on vessel diameter

What is the function of the coronary sinus?

• Oxygenation of blood

• Draining deoxygenated blood from the heart

• Pumping blood into the pulmonary trunk

• Oxygenating blood in the lungs

What is the primary role of the Circulatory System?

• Transportation of oxygen from the lungs to the tissues

• Transportation of nutrients from the liver to all parts of the body

• Transportation of waste products to the kidneys

• Transportation of hormones from the endocrine glands to target tissues and organs

What is the primary role of the intercalated discs in cardiac muscle?

• Nutrient exchange between cells

• Mechanical junctions for structural support

• Electrical junctions for cell communication

• Storage of calcium ions

The left side of the heart serves which circuit?

• Pulmonary circuit

• Lymphatic circuit

• Digestive circuit

• Systemic circuit

What characterizes the right side of the heart in terms of circulation?

• Supplies blood to the alveoli of the lungs

• Serves the systemic circuit

• Receives deoxygenated blood from the body

• Pumps oxygenated blood into the aorta
