Circulation: Heart, cardiac cycle, blood pressure

The human heart is one of the most vital organs of the circulatory system that pumps blood through blood vessels. The human heart and the cardiac cycle is important as it helps in understanding how oxygen and nutrients are carried to body parts. The heart is also responsible for removing metabolic waste and CO2 from […]

An electrocardiogram (ECG) is a test that assesses the electrical activity of the heart. Find out when it’s finished, as well as when other tests, like an exercise ECG stress test or event monitoring, are completed. When is an ECG used? To diagnose and monitor heart issues, an ECG is routinely used in conjunction with

It is a condition in which an individual’s blood pressure is unusually high. Such a person may be under a lot of psychological strain. If this situation persists, it may lead to a variety of additional serious health problems, such as heart disease, stroke, and so on. Before diving into this subject, you should first

This article contains cardiac output, cardiac output formula and normal cardiac output. Vertebrates circulate blood (a fluid connective tissue) in the body to transport essential and nonessential products. Blood comprises red blood cells (RBCs/ erythrocytes), white blood cells (WBCs/ leukocytes) and platelets (thrombocytes). The human circulatory system consists of a muscular pumping organ (heart). About

Generally speaking, the pulse rate is defined as the number of heartbeats per minute.  The resting pulse rate of an average adult ranges between 60 and 80 beats per minute, depending on their age.  ‘Heart rate’ refers to the rate at which the beating of the heart occurs in the human body. Placing your finger

Key pointers Each ventricular contraction sends a wave of blood through the arteries, which is detectable as a pulse. A healthy adult’s pulse rate ranges from 60 to 100 beats per minute. Furthermore, the body will adjust its heart rate to compensate for any variations in stroke volume. The sympathetic nervous system raises the heart

Introduction The heart, as we all know, beats ceaselessly. Have you ever wondered what would occur if a component of the circulatory system stopped working correctly? What would be the consequences? In most cases, heart failure. There are numerous causes of heart failure. It might be that your heart is not powerful enough to pump

The heart is an organ that acts as a pump to circulate blood throughout the body. Located between the two lungs and also to the left of center, behind the rib cage, it relies on the diaphragmatic, which is a muscular wall that separates the breast chest from the abdomen in humans and other mammals.

Each of the four primary coronary arteries is named after one of the four major arteries in the body: the right coronary artery (RCA), the left coronary artery (LCA), the left anterior descending (LAD), and the left circumflex artery. Cardiovascular disease is a constriction or blocking of your coronary arteries that is typically caused by

Routine checking of blood pressure, heart rate, pulse rate, oxygen saturation, body temperature helps in quick and easy diagnosis of any underlying conditions. For instance, using a  glucose metre to check the blood sugar levels in patients to check if they have diabetes or not is a relatable example of patient monitoring. Early detection can
