Pitot Tube

Pitot Tube

Principle of Pitot Tube: Based on Bernoulli’s theorem. Measures the difference between the stagnation pressure and static pressure to determine fluid velocity. Formula: $v = \sqrt{\frac{2\Delta P}{\rho}} $ Where: v = flow velocity ΔP = difference between stagnation pressure and static pressure ρ = fluid density Construction of Pitot Tube: Pitot Tube: L-shaped tube with … Read more

Venturimeter

Principle of Venturimeter: Based on Bernoulli’s theorem. The fluid’s velocity increases, and pressure decreases as it passes through the throat of the Venturimeter. Formula: $Q = C_d A_1 \sqrt{\frac{2\Delta P}{\rho \left(1 – \left(\frac{A_2}{A_1}\right)^2 \right)}}$ Where: Q = flow rate Cd​ = discharge coefficient A1​ = cross-sectional area of the pipe before the converging section A2​ … Read more

Disorders of heart

Disorders of heart

There are many disorders of heart, which can be broadly categorized into structural, electrical, and circulatory issues. Some common disorders of heart Coronary Artery Disease (CAD) Cause: Narrowing or blockage of the coronary arteries due to plaque build-up (atherosclerosis). Symptoms: Chest pain (angina), shortness of breath, increased risk of heart attack. Heart Attack (Myocardial Infarction) … Read more

Stomach Anatomy

Anatomy Stomach

Stomach is a key organ in the digestive system, acting as a reservoir for food, initiating the digestive process through mechanical mixing and chemical breakdown, and regulating the passage of its contents into the small intestine. Understanding the detailed anatomy of the stomach reveals how it is uniquely designed to perform these functions. Location and … Read more

Mouth

The oral cavity, or mouth, marks the entry point of the digestive system, equipped with specialized structures for the initial processing of food. Here, food encounters teeth and salivary glands, which work in concert to reduce food to a consistency suitable for digestion and absorption further down the GI tract. Teeth: The Tools for Mechanical … Read more

Anatomy of GI Tract

human gastrointestinal (GI) tract

The Anatomy of GI Tract, also known as the digestive tract, is a continuous tube that runs from the mouth to the anus. It is responsible for breaking down food, absorbing nutrients, and eliminating waste. Here’s a brief overview of the four primary layers of the gastrointestinal tract (GIT) The innermost layer responsible for secretion, … Read more

Electrocardiogram

Components of an ECG (Electrocardiogram)

An electrocardiogram (ECG or EKG) is a non-invasive diagnostic test that records the electrical activity of the heart over time. It is commonly used to detect and analyze heart-related problems, including abnormal rhythms, inadequate blood flow, and structural issues. How an ECG Works: The ECG measures the electrical changes on the skin produced by the … Read more

Cardiac output

Cardiac output

Cardiac output (CO) is a measure of the volume of blood pumped by the heart in one minute. It is a crucial indicator of the efficiency of the heart and the circulatory system in delivering oxygen and nutrients to the body’s tissues. Factors Determining Cardiac Output CO is determined by two primary factors: Heart Rate … Read more

Heartbeat Regulation by the Autonomic Nervous System (ANS)

Heartbeat Regulation by the Autonomic Nervous System (ANS)) plays a crucial role in regulating the heartbeat and maintaining cardiovascular homeostasis. The ANS consists of two primary branches: the sympathetic nervous system (SNS) and the parasympathetic nervous system (PNS), both of which have opposing effects on heart function. Sympathetic Nervous System (SNS) Role: Responsible for the … Read more
