Systolic and Diastolic Blood Pressure

What’s Systolic and Diastolic Blood Pressure?

Blood pressure is a vital sign that reflects the pressure of blood against the walls of arteries. Systolic blood pressure is the pressure in the arteries when the heart contracts and pumps blood out into the body, while diastolic blood pressure is the pressure in the arteries when the heart is at rest between beats. This article will provide an in-depth look at the differences between systolic and diastolic blood pressure, and why they are important .

Heart Valves- Types, Location, Structure and Functions

Heart Valves- Types, Location, Structure and Functions

The human Heart has four chambers, and four valves ensure that blood flows in the correct direction. The valves are made up of thin flaps of tissue that open and close like doors. There are four main types of Heart valves – the Aortic Valve, Mitral Valve, Pulmonary Valve and Tricuspid Valve. Each valve plays a vital role in regulating blood flow in and out of the Heart. Any problems with the valves can lead to a variety of conditions that affect Heart function.

Veins – Structure , functions ,Venous System and Circuits and Vein Valves 

Veins are vital blood vessels that collect oxygen-poor blood and transport it back to the heart. They are made up of three layers of tissue and fibers, and can contain one-way valves that keep blood flowing in the right direction. Veins transport oxygen-poor blood throughout the body and oxygen-rich blood from the lungs back to the heart. Veins require external forces such as breathing and muscle movement to push blood in the right direction.

Types of Veins and their Functions

Veins are essential for the circulatory system, transporting blood back to the heart. Four main types of veins include pulmonary, systemic, superficial and deep veins, each with unique characteristics. Pulmonary veins carry oxygenated blood from the lungs to the heart’s left atrium, while systemic veins transport deoxygenated blood from the body’s tissues back to the heart. Superficial veins are smaller and near the skin’s surface and deep veins are larger and deeper in the body.

Arteries of The Body

Arteries in The Body

Arteries in the body are an essential component of the Circulatory System. There are two main circuits- Pulmonary and Systemic Circuit. Arteries are classified based on their size and composition. Elastic arteries, such as the aorta, are the largest and most flexible, while muscular arteries and arterioles are responsible for directing blood flow to specific areas. Major arteries, including those in the head and neck, torso, abdomen, arms and legs play vital roles in delivering oxygen and nutrients throughout the body.

What are Arteries

Arteries – Structure , Layers,  Functions

Arteries are essential blood vessels responsible for carrying oxygen-rich blood away from the heart and distributing it throughout the body. Arteries are thick, muscular, and elastic, designed to withstand high pressure. Arteries have three main layers – the Tunica Intima, Tunica Media and Tunica Adventitia – each with distinct structures and functions.

formation of lymph

How Lymph is Formed ?

The lymphatic system is responsible for maintaining proper fluid balance and immune function in the body. Lymph is formed through a complex process that involves the collection of excess fluid from the tissues, entry into lymphatic capillaries, transport through lymphatic vessels, filtration in lymph nodes and return to the bloodstream. Factors such as exercise, gravity and disease can affect lymph formation and have significant implications for overall health and wellness.

Cardiac Cycle – Class 11th 

The cardiac cycle is the series of events that occur during one heartbeat where the heart contracts and relaxes to pump blood. It includes diastole and systole in which the heart’s chambers fill with blood and then contract to eject blood. The cardiac cycle is regulated by electrical signals, nervous system input, hormones, and it is important for diagnosing and treating heart conditions.
