Integrative Physiology: Hemodynamics I & II

A set of flashcards covering key vocabulary and concepts from the lecture on hemodynamics in integrative physiology.

Stroke Volume

The volume of blood pumped from the left ventricle of the heart with each heartbeat.

Cardiac Output

The amount of blood the heart pumps in one minute, calculated as heart rate multiplied by stroke volume.

Mean Arterial Pressure (MAP)

The average arterial pressure during a single cardiac cycle.

Total Peripheral Resistance

The total resistance to blood flow in the systemic circulation.

Sympathetic Nerves to Heart

Nerves that increase heart rate and contractility.

Parasympathetic Nerves to Heart

Nerves that decrease heart rate.

Plasma Epinephrine

A hormone that increases heart rate and myocardial contractility; released from the adrenal medulla.

Arteriolar Radius

The diameter of arterioles, which affects blood flow and resistance.

Blood Viscosity

The thickness and stickiness of blood, influencing resistance to flow.

Angiogenesis

The formation of new blood vessels from pre-existing vessels.

Pulse Pressure

The difference between systolic and diastolic pressure in the arteries.

Edema

Swelling caused by excess fluid trapped in the body's tissues.

Baroreceptor Reflex

The mechanism by which blood pressure is regulated by the autonomic nervous system through baroreceptors.

Coagulation Cascade

The series of events that lead to blood clotting.

Blood Typing

The classification of blood based on the presence or absence of specific antigens on the red blood cells.
