Heart Rate And Its Effect On The Human Body

Did you know the your heart is the size of both of your hands clapped together. The heart is a organ that keeps you alive. It is in your chest protected by the rib cage. The purpose of this paper is to summarize information about the heart, explains how it works, and discuss its purpose.

In a normal human being the heart correctly functions by the blood first entering through the right atrium from the superior and inferior vena cava. This blood flow continues through the right atrioventricular valve into the right ventricle. The right ventricle contracts forcing the pulmonary valve to open leading blood flow through the pulmonary valve and into the pulmonary trunk. Blood is then distributed from the right and left pulmonary arteries to the lungs, where carbon dioxide is unloaded and oxygen is loaded into the blood. The blood is returned from the lungs to the left

Oxygen and nutrients the body requires for function are pumped around this complex network of blood vessels by the heart. At roughly the size of a human fist, the heart is a four-chambered muscle and performs two functions of circulation simultaneously and continuously. Systemic and pulmonary circulation. The heart is made up from three separate layers of cardiac tissue; the outer layer called the pericardium, which is a double sac-like outer covering with serous fluid inside to keep the middle layer, the myocardium from adhering to the outer layer. This middle layer of the heart is the heart muscle which is thicker on the left side, to aid with the pressure needed to sustain systemic circulation. The inner layer of the heart is the endocardium. It’s lining is smooth to help prevent the blood which circulates around the inside of the heart from clotting. The heart is the human body’s in-built pacemaker, and the electrical signals sent through the it cause the heart to contract and relax. This process is triggered by the autonomic nervous system and the contraction and relaxing cycle is

The heart is a very strong muscle that has one major job. The heart’s job is to pump blood throughout the entire body. The heart is made up of 4 chambers, and 4 valves. There is the right and left atrium, and a right and left ventricle. The atriums are the superior chambers, and the ventricles are inferior chambers. The left ventricle is the most important, because that is where the blood travels through to go to the aorta, and eventually the rest of the body (Taylor 2015).

In addition, heart rates vary according to exercise, physical needs, age, gender, air temperature, etc. In this experiment the dependent variable

Almost 80% of people die from heart disease. The only way to know your level of risk is to be assessed by a healthcare professional and to be checked for factors such as your blood pressure, cholesterol and glucose levels, waist measurement and BMI. Once you know your overall risk, agree with your healthcare professional on a plan for specific actions you should take to reduce your risk for heart disease and stroke. The Circulatory System is made up of three main parts: The heart, the blood vessels and the blood. Sometimes the watery fluid called lymph and the vessels that carry it are considered to be part of the Circulatory System. The heart is a special pump that pumps the blood around the body. The purpose of this paper was to summarize information about the heart, explain how it works, and discuss its purpose. It was said that the heart evolves through several different stages inside the womb, first resembling a fish's heart, then a frog's, which has two chambers, than a snake's, with three, before finally adopting the four-chambered structure of the human heart. I also told you how the heart works. When the heart contracts, the chambers become smaller, forcing blood first out of the atria into the ventricles, then from each ventricle into a large blood vessel connected to the top of the heart. Now the purpose of the heart is the size of its owner's clenched fist, the organ sits in the middle of the chest, behind 1the breastbone and between the lungs, in a moistened chamber that is protected all round by the rib cage. It can also be easy to fix the heart. The only way to know your level of risk is to be assessed by a healthcare professional and to be checked for factors such as your blood pressure, cholesterol and glucose levels, waist measurement and BMI. The heart is very important for your

This article will explore your heart's anatomy. We'll describe its exterior, including the arteries and veins that supply blood to the muscle. We'll also describe the organ's interior, including the chambers, valves, and blood flow. Lastly, you'll learn how its electrical system helps ensure its proper function.

Mammals have four-chambered hearts and double circulation. The double-loop circulation is similar to amphibians and reptiles, but the oxygen-rich blood is completely separated from oxygen-poor blood. The left side of the heart handles only oxygenated blood, and the right side receives and pumps only deoxygenated blood. With no mixing of the two kinds of blood, and with a double circulation, delivery of oxygen to all parts of the body is enhanced. The gross anatomy of the human heart is the same as the sheep’s heart that was dissected. The heart is located, between the lungs, and behind the sternum. At least one blood vessel attaches to each of the chambers. It usually beats from 60 to 100 times per minute, but can go much faster when it needs to. It beats about 100,000 times a day, more than 30 million times per year, and about 2.5 billion times in a 70-year lifetime.

The human heart is a found within the chest cavity surrounded by the lungs. Roughly the size of a fist, the heart is a tenacious automated muscular unit that directs oxygenated blood through a sequence of four chambers. Inside these chambers there are four corresponding valves which permit blood to travel in the forward direction. On any given day the heart beats 100,000, and is capable of perfusing blood throughout the bodies’ 60,000 mile system of blood vessels (Christensen & Kockrow, 2011).

Heart rate, also known as pulse, is the number of times a person's heart beats per minute. A normal heart rate depends on the individual, age, body size, heart conditions, whether the person is sitting or moving, medication use and even air temperature. Even emotions can have an impact on heart rate. For example, getting excited or scared can increase the heart rate. But most importantly, getting fitter lowers the heart rate, by making heart muscles work more efficiently.

Which of the various food types (Sweet, sour, spicy, bitter and salty) will have the most substantial effect on a teenage girls heart rate?

The heart beats about 1000,000 times every day sending 2,000 gallons of blood thought your body. The hearts job is keeping blood flowing through 60,000 miles of blood vessels that feed organs and tissues. The cardiac muscle is the tissues that make up your heart. The heart sends blood around your body. When there is a problem with your heart and it can’t pump blood it is critical for it to be fixed. This is when the cardiovascular surgeon steps in.

Heart rate is the number of times a minute our heart makes a beat. It is a very vital sound. There are two parts to each heartbeat. The first part is when the heart contracts and pumps blood, is called the 'systole' (sis-tol). The second part is when the heart relaxes so the chambers can refill with blood, is called 'diastole' (di-as-tol). Heart rate is what causes blood to run through your arteries. The heart uses a lot of force to pump blood to the whole body. If your heart stops working then none of your body will be able to get blood and you most likely die if some can’t get your heart to start back up again. The heart is one of the most vital arteries in the body.

The heart is a muscular organ in charge of pumping blood to all parts of the body. As the heart contracts, the blood is forced out through blood vessels and begins to follow a specific pathway. The blood makes it way through pulmonary circulation (to the lungs) and then through systemic circulation (the rest of the body).

The heart is what keeps all living breathing species alive, animals or humans. If the heart was to shut down but the nervous system continued and was active, it would not matter. The entire body would shut down because once the supplier no longer delivers what is needed; organs will no longer function correctly, therefore causing irreversible damage. Arteries are what carried the rich oxygenated blood from the heart to the rest of the organs throughout the body. The Veins are what bring back the carbon dioxide blood to the heart. It then has to be put through a cycle so that it can be shipped back out. Blood travels from the right atrium through the tricuspid valve, to the right ventricle. From there, it is pumped to the lungs, the oxygen-rich blood goes to the left atrium and then through the mitral valve to the left ventricle where it goes to the aorta to be pumped around the body (Colombo 7). What looks to be a complicated process that would take hours or minutes is actually done in a matter a seconds.
