An analysis of the effects of exercise in the human heart rate

Body temperature Decrease in body temperature Using a combination of autorhythmicity and innervation, the cardiovascular center is able to provide relatively precise control over the heart rate, but other factors can impact on this. These include hormones, notably epinephrine, norepinephrine, and thyroid hormones; levels of various ions including calcium, potassium, and sodium; body temperature; hypoxia; and pH balance. The other component is sympathetic stimulation.

Next Chambers of the Heart The heart is a muscular organ about the size of a fist, located just behind and slightly left of the breastbone. The heart pumps blood through the network of arteries and veins called the cardiovascular system. The heart has four chambers: The right atrium receives blood from the veins and pumps it to the right ventricle.

The right ventricle receives blood from the right atrium and pumps it to the lungs, where it is loaded with oxygen. The left atrium receives oxygenated blood from the lungs and pumps it to the left ventricle. The left ventricle the strongest chamber pumps oxygen-rich blood to the rest of the body.

The coronary arteries run along the surface of the heart and provide oxygen-rich blood to the heart muscle. A web of nerve tissue also runs through the heart, conducting the complex signals that govern contraction and relaxation.

Surrounding the heart is a sac called the pericardium. Heart Conditions Coronary artery disease: Over the years, cholesterol plaques can narrow the arteries supplying blood to the heart.

Narrowed coronary arteries cause predictable chest pain or discomfort with exertion. The blockages prevent the heart from receiving the extra oxygen needed for strenuous activity. Symptoms typically get better with rest.

Chest pain or discomfort that is new, worsening, or occurs at rest. This is an emergency situation as it can precede a heart attack, serious abnormal heart rhythm, or cardiac arrest.

Myocardial infarction heart attack: A coronary artery is suddenly blocked. Starved of oxygen, part of the heart muscle dies. An abnormal heart rhythm due to changes in the conduction of electrical impulses through the heart.

Some arrhythmias are benign, but others are life-threatening. The heart is either too weak or too stiff to effectively pump blood through the body.

INTRODUCTION

Shortness of breath and leg swelling are common symptoms. Inflammation of the heart muscle, most often due to a viral infection.

Inflammation of the lining of the heart pericardium. Viral infections, kidney failure, and autoimmune conditions are common causes. Fluid between the lining of the heart pericardium and the heart itself. Often, this is due to pericarditis. Abnormal electrical impulses in the atria cause an irregular heartbeat.

Atrial fibrillation is one of the most common arrhythmias. There are four heart valves, and each can develop problems.Heart Rate, Blood Pressure, and Exercise file “11a Heart Rate BP Exercise” from the Human Physiology with Vernier folder.

DATA ANALYSIS 1. Describe the trends that occurred in the systolic pressure, diastolic pressure, mean arterial pressure and pulse with exercise. Assume that the stroke volume increased from 75 mL/beat. Abstract Your heart starts beating before you are born and keeps right on going through your whole life.

Over an average lifetime, the human heart beats more than billion times. Keeping your heart healthy means eating right, not smoking, and getting regular exercise. Positive, negative effects of smartphone use and exercise Date: May 13, Source: Kent State University Summary: Researchers assessed how common smartphone uses -- texting and talking.

Step 3: Analysis

Take heart rate at the end of the exercise, and then every minute until the heart rate returns to near their normal level. for few minutes. Plot heart rate against time after exercise.

Plot recovery time against duration of exercise. Heart Rate and Exercise Literature Review The human heart is a very complicated organ, with the main purpose to pump life sustaining blood throughout the human body It also supplies oxygen and nutrients to all areas and clears harmful waste from the body.
