Circulation: Heart, cardiac cycle, blood pressure

Hypertension (high blood pressure) is a frequent disorder in which the blood’s long-term force against the artery walls is high enough to produce health problems such as heart disease. The amount of blood our heart pumps, as well as the amount of resistance to blood flow in our arteries, influence our blood pressure. The greater […]

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

The heart is one of the most vital organs of our body. It is part of our body’s circulatory system. The job of the heart is to circulate the supply of blood, oxygen, hormones, and nutrients to all parts of the body with the help of blood vessels. To do this, the heart needs to

Any or all cardiovascular system components might suffer from abnormalities or damage that can cause significant health problems. Coronary artery disease, heart attack, excessive blood pressure, or stroke are all common disorders that can impact the cardiovascular system. The cardiovascular system, along with its components and functions, is the subject of this article. We also

Blood travels via the arteries to various parts of the body while the heartbeats. The blood flow’s pulse and the pressure it exerts on the body alter throughout time. If the pressure is abnormally high, it may indicate that the person has high blood pressure, which is harmful. Additionally, if the pressure is very low,

Simple organisms like coelenterates and sponges spread water from the surroundings through their body cavities to exchange these chemicals between cells. More sophisticated creatures need specific fluids within their bodies to transfer such elements. Most higher creatures, including humans, use blood as the most frequent bodily fluid. Symptoms of angina chest pain discomfort is a

Introduction The human heart is an important organ made up of muscles. It is located in the middle of the chest and tilts to the left. Its main function is to clean the blood and pump it throughout the body. The heart of a woman beats 8 times more than that of men.  The human

Introduction The size of the human heart is that of a human fist, and it has four chambers along with two ventricles and two atria. The blood-pumping chambers are called ventricles, and the blood-receiving chambers are called atriums. The right atrium and ventricle make the “right heart,” while the left atrium and ventricle make up

The heart is an organ that acts as a pump to circulate blood throughout the body. Molluscs have a heart that is either a straight tube, as in spiders, or a more complicated system with one or more receiving chambers (atria) and the main pumping chamber (ventricle), as in spiders and annelid worms. When viewed

The structure of the Atrial natriuretic factor shifts fluid from the intravascular to the interstitial chamber and antagonises vasoconstriction in the cardiovascular system. It also guards against unnecessary plasma volume expansion by increasing the total extracellular volume of the fluid. It is also known as the physiological modulator of (GFR – Glomerular filtration rate), a
