Cardiovascular System Review

Cardiovascular System Review

• Blood Pressure Control: The sympathetic nervous system is responsible for vasomotor tone.

• Blood Pressure: Blood pressure of 120/80 mmHg has a diastolic pressure of 80 mmHg.

• Blood Pressure: If blood pressure is 110/80 mmHg, pulse pressure is 30 mmHg.

• Blood Flow: Blood flow is inversely proportional to peripheral resistance.

• Blood Vessel Function: Capillaries are the site of exchange between blood vessels and cells.

• Venules: Venules unite to form veins.

• Blood Vessel Structure: Smooth muscle is a component of blood vessel walls.

• Blood Vessel Structure: Capillaries are the smallest blood vessels.

• Blood Vessel Structure: The tunica media is the muscular layer of blood vessels.

• Blood Vessel Function: Arterioles control blood flow to tissues.

• Blood Vessel Function: Sinusoids are highly modified capillaries. Also:

  • Arteries, arterioles, venules, capillaries are all forms of blood vessels.

• Blood Vessels: The internal carotids supply 80% of the cerebrum's blood flow

• Blood Flow: The ascending aorta is the first part of the aorta

• Blood Flow: Low oxygen levels in skeletal muscle result in vasoconstriction.

• Circulation and Blood Flow: The correct answers for the multiple choice questions, regarding the various parts of the circulatory system.

• Heart Conduction: A P wave denotes atrial depolarization. The PQ segment refers to the time when the impulse is delayed at the AV (Atrioventricular)node. The QRS complex signals ventricular depolarization, followed by atrial repolarization. An S-T segment signifies complete depolarization of the ventricles. The T wave shows ventricular repolarization.

Heart Anatomy

• Heart Anatomy: The image displays the four heart chambers (right atrium, left atrium, right ventricle, left ventricle) as well as major blood vessels and valves (tricuspid valve, mitral/bicuspid valve, aortic valve, pulmonary valve)

Blood Types

• Blood Types: Images provided illustrate blood typing.

This quiz focuses on the key concepts of the cardiovascular system, including blood pressure control, blood flow dynamics, and the structure and function of blood vessels. Test your knowledge on how different blood vessels operate and their significance in the circulatory system.
