Cardiovascular fitness the circulatory system
The document discusses the circulatory system and cardiovascular fitness. It defines cardiovascular fitness as the ability to exercise for long periods with a strong heart and clear blood vessels. The circulatory system functions to circulate blood, transport oxygen and nutrients to cells, and remove waste. The heart is a muscular pump divided into four chambers that uses a double circulatory system to oxygenate blood in the lungs and transport it to the body and back. Smoking can increase risks by blocking arteries and raising blood pressure. Blood pressure should be monitored and can be managed through weight control, limiting alcohol, avoiding smoking, reducing salt, and regular exercise to control stress.
Hemodynamic
Hemodynamic stability refers to stable blood flow, with a stable heart pump and good blood circulation. Hemodynamic instability is any instability in blood pressure that can lead to inadequate blood flow to organs. Signs of instability include hypotension, abnormal heart rate, shortness of breath, cyanosis, decreased urine output, and loss of consciousness. Hemodynamic stability can be diagnosed by checking vital signs like respiratory rate, pulse, blood pressure, and urine output. Complications of instability include hemorrhage, thrombosis, embolism, and arterial spasm.

The document discusses the human circulatory system and blood transport. It describes the roles of different blood vessels like arteries, veins, and capillaries in transporting blood throughout the body. It also explains how blood flow is regulated through the constriction and dilation of blood vessels and redirected to parts of the body that need more oxygen during exercise through vascular shunting. The document also covers topics like oxygen transport by hemoglobin and myoglobin, the Bohr shift, carbon dioxide transport, and the arterio-venous oxygen difference.
Circulatory System Physiology [Zoo 403]
This presentation provides a clear understanding of the physiology of the circulatory system. It focus lies on the division and component of the circulatory system, the three major function of the circulatory system, blood composition, structure of the heart, blood circulation; pulmonary and systemic circuit, valves of the heart, the pathway of blood flow through the heart, the cardiac cycle, pressure changes during the cardiac cycle; systole and diastole, cardiac output, heart sounds among others.
This presentation was designed by Fasama H. Kollie and presented by Benetta N. Kekulah, Cordelia Capehart and Abraham Peters.
Cardiorespiratory system 3º
The document summarizes the cardiorespiratory system and its response to exercise in 3 parts. The respiratory system is responsible for gas exchange and increases ventilation during exercise. The cardiovascular system transports oxygen and nutrients to tissues and removes waste; it responds to exercise by increasing heart rate, stroke volume, and cardiac output to deliver more oxygen to active muscles. Regular exercise can increase lung capacity and lower resting heart rate over time.
Anatomy lab. 6 cardiovascular sys.
The cardiovascular system consists of the heart and blood vessels. The heart is a cone-shaped organ located in the thoracic cavity between the lungs. It has four chambers - two upper atria and two lower ventricles separated by valves. Blood flows from the right atrium to ventricle to lungs then left atrium to ventricle and out to the body via the aorta. The cardiovascular system transports blood to the lungs for oxygenation and throughout the body, circulating nutrients and removing waste.

Unit 5 cardiorespiratory system
The cardiorespiratory system is responsible for endurance and is composed of the cardiovascular and respiratory systems. The respiratory system removes carbon dioxide from the body and intakes oxygen through breathing, which has two phases - ventilation that moves air in and out of the lungs, and diffusion where gases are exchanged. During exercise, lung volume, breath rate, and cardiac output increase to supply more oxygen to working muscles. The cardiovascular system transports oxygen and nutrients to tissues through blood circulation. When exercising, the heart rate and stroke volume rise to boost cardiac output and increase blood flow to active muscles.

Hemodynamics
Hemodynamics is the study of blood flow through the cardiovascular system. It focuses on how the heart pumps blood throughout the body while supplying oxygen to organs and tissues. Problems with hemodynamics can cause serious health issues like hypertension. Key elements of the hemodynamic system include heart rate, stroke volume, cardiac output, systemic vascular resistance, and blood pressure. Regular exercise is an effective way to increase blood flow by getting the heart to pump more blood throughout the body.
Cardiorespiratory presentation
The circulatory and respiratory systems are closely linked. The circulatory system transports oxygen to tissues via blood flow and removes carbon dioxide through a dual circuit pathway. The respiratory system oxygenates blood in the lungs through gas exchange and is regulated to meet metabolic demands through controlled breathing. Diseases that impact these systems like COPD and heart attacks disrupt their functions and ability to effectively deliver oxygen and remove wastes.
Cardiac Cycle
The cardiac cycle describes the sequence of events in the heart from one heartbeat to the next. It involves the coordinated contractions and relaxations of the atria and ventricles. There are seven phases in the cardiac cycle: 1) atrial systole, 2) isovolumetric ventricular contraction, 3) rapid ventricular ejection, 4) slow ventricular ejection, 5) isovolumetric ventricular relaxation, 6) rapid ventricular filling, and 7) slow ventricular filling. The cycle ensures blood is pumped efficiently from the heart to the lungs and body.
Presentation1
This document discusses the musculoskeletal and respiratory systems. It provides information on muscles, their relationships during movement, and types of muscle contractions. It also describes the main components and functions of the respiratory system, including how oxygen is absorbed and carbon dioxide discharged. The circulatory system is then covered, outlining the components of blood, structure and function of the heart, arteries, veins, capillaries, and pulmonary and systemic circulation. Blood pressure measurement using a sphygmomanometer is also summarized.
2 systemic circulation.pptx
The systemic circulation provides oxygenated blood from the left ventricle to tissues throughout the body and returns deoxygenated blood to the right atrium. Factors that affect blood flow in the systemic circulation include the cross-sectional area of vessels, pressures at different points, vascular resistance, venous return, blood viscosity, and the distensibility and compliance of blood vessels. The systemic circulation supplies all body tissues except the lungs.
Cardiac cycle.full
The cardiac cycle consists of relaxation (diastole) and contraction (systole) of the heart. Each cycle begins with an electrical impulse from the sinus node which causes atrial contraction and is recorded as the P wave on an ECG. Contraction of the ventricles follows, recorded as the QRS complex, pumping blood into the arteries. Ventricular relaxation is recorded as the T wave. The heart's pumping is regulated intrinsically via the Frank-Starling mechanism and extrinsically by the autonomic nervous system.
Cardiac Cycle
The cardiac cycle describes the sequence of events in the heart from one heartbeat to the next. It involves rhythmic contractions and relaxations of the heart's chambers. Each cycle includes a systole, where the ventricles contract to pump blood out, and a diastole, where the ventricles relax and refill. The cycle is initiated by an electrical impulse from the sinoatrial node and involves pressure, volume, and valve changes in the heart chambers and arteries with each beat.
Chapter 1 cardiovascular system
In this course you will learn the cardiovascular system is Responsible for transporting oxygen, nutrients, hormones, and cellular waste products throughout the body, the cardiovascular system is powered by the body's hardest-working organ — the heart, which is only about the size of a closed fist.
Cardiovascular system ppt
The cardiovascular system consists of the heart and blood vessels. The heart is a double pump that delivers oxygenated blood to the body and deoxygenated blood to the lungs. Blood flows from the heart through arteries and returns through veins. The heart rate and cardiac cycle are regulated by the cardiac conduction system and the cardiac center in the medulla oblongata, which controls sympathetic and parasympathetic input. Blood pressure is affected by heart rate, blood volume, peripheral resistance, and viscosity and its regulation is important to prevent conditions like hypertension.
Cardiovascular System
The cardiovascular system consists of the heart, which acts as a double pump to circulate oxygenated blood received from the lungs throughout the body via arteries, and to return deoxygenated blood to the lungs via veins. The heart's rhythm is regulated by a conduction system and the autonomic nervous system. Blood pressure is controlled by factors like heart rate, blood volume, vessel resistance and viscosity. Arteries and veins have distinct structures suited to their roles in blood transport, and the circulatory system enables dynamic responses to meet the body's changing needs.
Anatomy-Bad Fish Unit: Cardiovascular Notes
The heart has four chambers separated by a septum, with two atria that receive blood and two ventricles that pump blood out. It is surrounded by membranes and layers. Veins carry deoxygenated blood into the right atrium while pulmonary veins carry oxygenated blood into the left atrium. The pulmonary artery carries blood from the right ventricle to the lungs and the aorta carries it from the left ventricle throughout the body. Valves ensure blood flows in one direction. The cardiac cycle involves the heart relaxing to fill with blood then contracting to pump it out in two phases controlled by the conduction system.
Summary
The document summarizes the structure and function of the respiratory and circulatory systems. It describes how air enters the lungs through the nose and trachea, reaching tiny alveoli where gas exchange occurs. Oxygen is delivered via blood to cells while carbon dioxide is transported to the lungs to be exhaled. The heart pumps blood to and from the lungs and throughout the body in a double circulation. Smoking harms these systems by increasing risks of diseases like bronchitis, emphysema and heart conditions. Maintaining a healthy lifestyle can prevent respiratory and circulatory issues.
The heart and cardiac cycle
The document summarizes the structure and function of the heart and cardiac cycle. It describes that the heart has four chambers - right and left atria which receive blood and right and left ventricles which pump blood. The heart pumps deoxygenated blood to the lungs and oxygenated blood to the rest of the body in continuous cycles. During each cycle, called the cardiac cycle, the heart contracts (systole) to pump blood and relaxes (diastole) to fill with blood.
Heart physiology & conduction system in short present by Tanveer A. Ansari
The heart is a muscular organ that pumps blood through the circulatory system. It is located in the middle of the chest, slightly left of the breastbone. The right side of the heart pumps blood to the lungs to pick up oxygen, while the left side receives oxygen-rich blood from the lungs and pumps it to the body. The heart's conduction system is responsible for contracting and relaxing the heart muscle, starting with electrical impulses generated in the sinoatrial node that travel through pathways to the ventricles.
Cardiovascular system (blood pressure, hypertension)
This document provides an overview of the cardiovascular system, including the cardiac cycle, cardiac rhythm, blood pressure, and hypertension. It discusses topics such as:
- The cardiac cycle occurs over 0.8 seconds and includes systole and diastole.
- Sinus rhythm is normally set by the sinoatrial node at a rate of 70-80 beats per minute.
- Blood pressure is the force of blood pushing against artery walls and is measured in millimeters of mercury (mmHg).
- Hypertension is defined as a systolic pressure over 140 mmHg or diastolic over 90 mmHg. It can be primary (essential) or secondary due to other medical conditions.

Dr. gautam heart
The heart is a muscular organ in most animals, which pumps blood through the blood vessels of the circulatory system. The pumped blood carries oxygen and nutrients to the body, while carrying metabolic waste such as carbon dioxide to the lungs. In humans, the heart is approximately the size of a closed fist and is located between the lungs, in the middle compartment of the chest.
Heart disease describes a range of conditions that affect your heart. Heart diseases include:
Blood vessel disease, such as coronary artery disease
Heart rhythm problems (arrhythmias)
Heart defects you're born with (congenital heart defects)

Congestive Heart Failure.pptx
Congestive heart failure is a condition where the heart cannot pump enough blood to meet the body's needs. It occurs when the heart muscle is damaged, such as from a heart attack or conditions that overwork the heart like high blood pressure. Symptoms include shortness of breath, swelling in the legs or abdomen, and fatigue. Treatment focuses on lifestyle changes, medications to manage symptoms and improve heart function, and sometimes surgery or implanted devices. Ongoing monitoring is needed to watch for changes in symptoms or physical signs that may indicate worsening of the condition.

СHD lecture.pptx
Coronary heart disease (CHD) is caused by a build-up of plaque in the coronary arteries that supply blood to the heart. Over time, plaque can harden or rupture, reducing blood flow. Reduced blood flow can cause chest pain called angina or lead to a heart attack if a large section of heart muscle dies from lack of oxygen. Symptoms may include chest pain or pressure, shortness of breath, fatigue, and swelling. Tests like EKGs, stress tests, echocardiograms, and angiograms can diagnose CHD. Treatments include lifestyle changes, medications, and procedures like angioplasty or bypass surgery to reopen blocked arteries.
CVS ppt
This document discusses the causes, symptoms, diagnosis, and treatment of angina. Angina is chest pain or discomfort that occurs when the heart muscle doesn't get enough oxygen. It is usually a symptom of coronary artery disease. The document describes the different types of angina and how doctors diagnose angina through tests like EKGs, stress tests, blood tests, and angiography. Treatment involves lifestyle changes, medications, procedures, and cardiac rehabilitation to reduce pain, prevent heart attacks, and treat the underlying heart condition.
The heart .pptx
The document discusses the anatomy and function of the heart. It describes how the heart is divided into four chambers - the right and left atria and ventricles. The left side receives oxygenated blood from the lungs and pumps it to the body, while the right side receives deoxygenated blood from the body and pumps it to the lungs. The document also discusses heart failure, which occurs when the heart muscles weaken and the ventricles enlarge, preventing the heart from pumping enough blood. Cardiac arrest is defined as when the heart suddenly stops beating due to electrical issues, which can quickly lead to death if not treated. Common causes of cardiac arrest include heart attack, which happens when a coronary artery becomes blocked, restricting

A guide to myocardial infarction
A myocardial infarction, or heart attack, occurs when one of the coronary arteries becomes blocked, preventing oxygenated blood from reaching an area of the heart muscle. This prolonged lack of oxygen can cause the death of heart muscle tissue. The most common cause of a heart attack is a buildup of fatty plaque in the coronary arteries. Risk factors that can lead to this blockage include hypertension, diabetes, high cholesterol, smoking, obesity, and a sedentary lifestyle. Symptoms of a heart attack can include chest pain, pain in other areas of the upper body, shortness of breath, sweating, weakness, and nausea. An electrocardiogram is often used to diagnose a heart attack and determine its location in order to
CAD presentation
The document discusses coronary artery disease and angina. It defines coronary artery disease as a narrowing of the coronary arteries due to plaque buildup, reducing blood flow to the heart. It describes the different types of angina like stable angina brought on by exertion and unstable angina, a form of acute coronary syndrome. It provides details on symptoms, classifications of angina severity, and differences between angina and a heart attack.
Chest pain ,chest pain 2014,
This document discusses the evaluation and diagnosis of chest pain. It notes that while chest pain can be caused by many life-threatening and non-life-threatening conditions, it is important for patients to seek medical evaluation due to the difficulty in distinguishing between causes without testing. A medical history and physical exam are important for evaluating potential causes, which can include conditions affecting the heart, lungs, chest wall, esophagus and abdomen. Based on the history and exam, targeted testing like EKGs, blood tests, imaging and other diagnostics may be used to determine the underlying cause.
04 the human_body
The document provides an overview of the major body systems and some related emergency care considerations. It describes the basic functions and main organs of each system, including: respiratory (lungs, breathing), circulatory (heart, blood vessels, transport oxygen/nutrients), musculoskeletal (bones, muscles, movement/support), nervous (brain, spinal cord, senses/control), integumentary (skin, protection/sensation), gastrointestinal (digestion/nutrient absorption), urinary (kidneys, waste removal), and reproductive (sex organs, reproduction). It notes injuries and illnesses that could threaten system functions like breathing issues, bleeding, fractures, altered mental status, and internal organ damage.

The Circulatory System
The circulatory system moves blood throughout the body using the heart and blood vessels. The heart has four chambers and pumps blood, which carries oxygen and nutrients, between the lungs and body. Blood pressure measures the force of blood flow, and high blood pressure increases health risks like stroke and heart attack. Blood contains red blood cells, which carry oxygen, white blood cells for infection-fighting, and platelets for stopping bleeding.
Heart
The heart is a muscular organ that pumps blood through two separate circulatory loops to transport oxygenated and deoxygenated blood without mixing. It has four chambers - the left and right atria which collect blood, and the left and right ventricles which pump blood out. The heart works by contracting its chambers in a precise sequence to draw in blood, pump it out, and ensure the lungs and body are continuously supplied with blood. Heart disease occurs when this process is disrupted due to issues like clogged arteries, weak pumping, or irregular heart rhythms, and can cause symptoms such as chest pain, trouble breathing, and swelling. Risk factors include high blood pressure, cholesterol, diabetes, obesity, and smoking.
blood ciculation.pptx
The circulatory system consists of three main circuits - the pulmonary circuit, systemic circuit, and coronary circuit. Blood circulates through the heart and vessels in a continuous loop, carrying oxygen, nutrients, hormones, and waste products. There are three main types of blood vessels - arteries, which carry oxygenated blood away from the heart; veins, which return deoxygenated blood to the heart; and capillaries, which connect arteries and veins and allow for exchange of materials. The circulatory system's functions include transporting nutrients/gases, protecting the body, regulating temperature, and maintaining fluid balance. Circulatory problems increase with age as the vessels become less elastic and plaque can build up.
