Physiology Lecture # 5 Study Notes: Hemodynamics – Poiseuille’s Equation
Poiseuille’s equation, named after the French physicist Jean Louis Marie Poiseuille, describes the steady, laminar flow of a viscous fluid through a cylindrical pipe. It’s a fundamental equation in fluid dynamics and plays a crucial role in understanding the behavior of fluids in various systems, such as blood flow in arteries or the flow of liquids in pipes.
CVS Physiology Lecture # 12 Study Notes: Autoregulation – Muscle Blood Flow
Muscle blood flow refers to the circulation of blood within the muscles of the body, supplying oxygen and nutrients while removing waste products. This process is essential for muscle function during both rest and physical activity.
Physiology Lecture # 1 Study Notes: General Principles of Cardiovascular Physiology
General principles of cardiovascular physiology encompass the fundamental concepts that govern the functioning of the cardiovascular system, which includes the heart, blood vessels, and blood. These principles are vital to understanding how blood is circulated, how oxygen and nutrients are delivered to tissues, and how waste products are removed.
CVS Physiology Lecture # 17 Study Notes: Electrophysiology of Heart
The electrophysiology of heart refers to the study of the electrical properties and patterns of the heart’s cells and tissues that underlie its rhythmic beating and coordination. The heart’s electrical system is responsible for initiating and regulating the cardiac cycle, ensuring that the heart contracts and relaxes in a synchronized manner.
CVS Physiology Lecture # 13 Study Notes: Autoregulation – Cutaneous Blood Flow
Cutaneous blood flow refers to the circulation of blood through the skin, which is an essential physiological process that contributes to the regulation of body temperature, maintenance of homeostasis, and overall health. The skin serves as a vital interface between the internal and external environments, and its blood flow dynamics play a crucial role in various bodily functions.
CVS Physiology Lecture # 15 Study Notes: Autoregulation – Coronary Blood Flow
Coronary blood flow is the circulation of blood within the blood vessels that supply the heart muscle (myocardium) with oxygen, nutrients, and other essential substances necessary for its proper functioning. The coronary circulation is crucial for maintaining the viability and performance of the heart, as it ensures the delivery of oxygen and nutrients while removing metabolic waste products.
CVS Physiology Lecture # 14 Study Notes: Autoregulation – Cerebral Blood Flow
Cerebral blood flow (CBF) refers to the blood supply to the brain in a given period. It is crucial for delivering oxygen and nutrients and removing waste products. CBF is regulated by mechanisms such as autoregulation, which maintains consistent flow despite changes in blood pressure. Disruptions in CBF can lead to conditions like stroke and are influenced by factors such as blood viscosity, vessel diameter, and neuronal activity.
CVS Physiology Lecture # 9 Study Notes: Blood Pressures
Blood pressure is the force exerted by circulating blood on the walls of blood vessels. It is measured in millimeters of mercury (mmHg) and recorded as two numbers: systolic pressure (the higher number, representing the pressure when the heart beats) over diastolic pressure (the lower number, representing the pressure when the heart is at rest). Normal blood pressure is typically around 120/80 mmHg.
CVS Physiology Lecture # 16 Study Notes: Blood Pressure Control by Baroreceptors
Baroreceptors are specialized sensory receptors located in the walls of certain blood vessels, particularly within the carotid sinuses and aortic arch. They play a crucial role in regulating blood pressure by sensing changes in arterial pressure and sending signals to the brain, specifically the medulla oblongata.
Physiology Lecture # 4 Study Notes: Hemodynamics – Blood Flow
Hemodynamics is the study of blood flow within the circulatory system. It involves the analysis of the physical principles governing blood movement, including pressure, flow, and resistance. Blood flow is driven by the heart’s pumping action and regulated by the resistance of blood vessels, which is influenced by vessel diameter, blood viscosity, and overall vessel length.
