Circulation: Heart, cardiac cycle, blood pressure

Introduction to the human heart  The heart in the human body is a muscular organ whose major function is to pump blood through an array of veins and arteries. The heart is almost the size of your fist. It transports the blood to all the parts of the body. The heart contains four chambers, and […]

The heart is the pumping organ of the body. It pumps blood all the time. It helps in transporting blood to all the parts of the body. The heart pumps blood through the set of connections between veins and arteries. The heart is present on the left side of the chest cavity. It is almost

The heart is one of the most crucial organs responsible for sustaining life. The heart is the pumping organ of the body. It pumps blood all the time. It helps in transporting blood to all the parts of the body. The heart pumps blood through the set of connections between veins and arteries. Throughout a

The human circulatory system is made up of blood cells, the heart, a network of veins, arteries and the lymphatic system. These four major parts are responsible for performing specific functions to keep the human body active, and healthy.  Imagine if your blood vessels or veins stop working even for a minute? It seems like

The circulatory system’s arteries and veins are two distinct classes of blood vessels that play diverse roles in transporting blood throughout the body. However, the functions of the two blood vessels are substantially distinct. For example, arteries convey oxygenated blood throughout the body, whereas veins transport deoxygenated blood to the heart except in cases where

Cardiac output refers to the abstraction of blood that the heart pumps in a minute, depending on the heart rate, preload, afterload and contractility. Understanding the pertinence of these four components is essential when understanding cardiac output. This article will use a very simple analogy for analysing cardiac output – an example of the speed

Hypertensive heart disease is a long-term disorder that affects persons with high blood pressure over time. When you don’t regulate your high blood pressure, it can lead to a slew of medical issues like heart failure and conduction arrhythmias (hypertension). Hypertensive heart disease is caused by chronically high blood pressure (greater than 120/80 mmHg). People’s

Blood vessels are channels that convey blood all through your body. They structure a circle, similar to a circuit, that starts and ends at your heart. Together, the heart vessels and blood vessels structure the circulatory framework. Our body contains around 60,000 miles of veins carefully structured around us. There are three main types of

Atrial natriuretic peptide (ANP) is a cardiovascular chemical that controls salt-water equilibrium and blood pressure by advancing renal sodium and water discharge and animating vasodilation. ANP has an enemy of hypertrophic work in the heart, which is autonomous of its foundational pulse, bringing down its impact. Since its inception, ANP has been known to be

The systolic phase is the first phase of the heartbeat. It starts with the heart contracting and can be detected with a stethoscope. The systolic phase begins when the first sound is detected, from a downward deflection of the heart’s wall, leading to increased pressure in the ventricles. The chamber then fills up with blood
