Study Notes

Cardiovascular Function

The cardiovascular system delivers oxygen and nutrients to cells, removes waste products, and transports hormones.
The systemic branch carries blood throughout the body, including arteries, veins, and capillaries, working with the lymphatic system.
The pulmonary branch carries blood to and from the lungs for gas exchange.

Heart Anatomy

The superior vena cava and inferior vena cava return deoxygenated blood to the right atrium.
From the right atrium, blood flows through the tricuspid valve to the right ventricle.
The right ventricle pumps blood through the pulmonic valve to the pulmonary arteries, carrying blood to the lungs for gas exchange.
Oxygenated blood returns from the lungs through the pulmonary veins to the left atrium.
Blood flows through the mitral valve into the left ventricle.
The left ventricle pumps blood through the aortic valve to the aorta, distributing oxygenated blood to the body.

Pulmonary Gas Exchange

Oxygen and nutrients from the blood are exchanged with carbon dioxide and waste products in the lungs.
This exchange occurs in the capillaries surrounding the alveoli in the lungs.
The alveoli are small air sacs in the lungs where gas exchange takes place.

Heart Valves

The tricuspid valve prevents backflow from the right ventricle to the right atrium.
The mitral valve prevents backflow from the left ventricle to the left atrium.
The aortic valve prevents backflow from the aorta to the left ventricle.
The pulmonic valve prevents backflow from the pulmonary arteries to the right ventricle.

Blood Flow Through the Heart (in detail).

Deoxygenated blood enters the heart through the superior and inferior vena cava.
Blood then flows into the right atrium.
From the right atrium, blood passes through the tricuspid valve into the right ventricle.
The right ventricle pumps blood through the pulmonic valve into the pulmonary arteries.
Oxygenated blood returns to the heart through the pulmonary veins.
Blood enters the left atrium.
From the left atrium, blood passes through the mitral valve into the left ventricle.
The left ventricle pumps blood through the aortic valve into the aorta, which distributes oxygenated blood to the rest of the body.

Electrical Conduction System of the Heart

The sinoatrial (SA) node, located in the right atrium, is the natural pacemaker.
Impulses originate in the SA node and spread through internodal tracts, causing atrial contraction.
The atrioventricular (AV) node delays the impulse, allowing the atria to fully empty before ventricular contraction.
Impulses travel through the bundle of His, bundle branches, and Purkinje fibers, causing ventricular contraction.

Cardiac Activity (in detail)

Depolarization is an increase in electrical charge.
Repolarization returns ions back to the cell membrane, preparing for the next depolarization.
An electrocardiogram (ECG) measures these electrical events.
Normal sinus rhythm originates in the SA node and has a rate of 60 to 100 beats per minute (bpm).
Dysrhythmias are abnormal heart rhythms that can have many causes.

Blood Vessels

Arteries carry oxygenated blood away from the heart.
Veins carry deoxygenated blood back to the heart.
Capillaries are the site of gas and nutrient exchange between the blood and tissues.
Blood vessels have three layers: tunica intima (inner layer), tunica media (middle muscular layer), and tunica adventitia (outer layer).

Lymphatic System

The lymphatic system returns excess interstitial fluid (lymph) to the circulation.
It aids in immunity.
Lymph nodes, spleen, thymus, and tonsils are components of the lymphatic system.

Cardiovascular Diseases

Pericarditis is inflammation of the pericardium, the sac surrounding the heart.
Infective endocarditis is an infection of the endocardium, the lining of the heart chambers and valves.
Myocarditis is inflammation of the myocardium, the heart muscle.
Valvular disorders affect the heart valves, impacting blood flow.
Cardiomyopathy involves weakened and enlarged myocardium, affecting cardiac output.
Dysrhythmias are abnormal heart rhythms.
Aneurysms are bulges or weakness in an artery wall.
Dyslipidemia involves high lipid levels in the blood.
Atherosclerosis is the thickening and hardening of arterial walls, often due to plaque buildup.

Peripheral Vascular Disease (PVD)

Causes: atherosclerosis, thrombus, inflammation, vasospasm.
Complications: peripheral vascular disease, coronary artery disease, thrombi, hypertension, and stroke.
Raynaud's phenomenon is associated with an autoimmune condition, causing a red white blue presentation in the hands

Thrombi

Stationary blood clots made up of various blood components (platelets, fibrin, erythrocytes).
Can form in response to inflammation of vessel walls, increased turbulence, and coagulation or other causes.
Can cause problems if they break off and travel as an embolism.
Symptoms of thrombi vary depending on location.

Varicose Veins

Engorged veins due to incompetent valves.
Often in the legs, can be in the esophagus (esophageal varices) or anorectal area.

Emphysema

Destruction of the alveoli, leading to overinflated lung tissue and poor gas exchange.
Often associated with smoking or other irritants.
Causes include alpha-1-antitrypsin deficiency.

Legionnaires' Disease

A form of pneumonia caused by Legionella pneumophila.
Often associated with humidifiers and environmental conditions

Asthma

Chronic obstructive airway disease.
Characterized by bronchospasm, inflammation, and mucus production.
Types: Intrinsic (not allergic) and Extrinsic (allergic).

Pulmonary Diseases (including conditions)

Pleural effusion is fluid accumulation in the pleural space.
Pneumothorax is air in the pleural space.

Acute Respiratory Distress Syndrome (ARDS)

Rapidly developing respiratory failure.
Results from fluid accumulation in the alveoli.
Causes: shock, burns, aspiration, smoke inhalation

Atelectasis

Collapse of alveoli.
Causes include surfactant deficiencies, bronchus obstruction, lung tissue compression or damage

Congenital Heart Defects

Structural issues with the heart present at birth.
Include septal defects, patent ductus arteriosus, and valve disorders.

Lung Cancer

Often caused by smoking.
Types: small cell, squamous cell, and large cell.

Cystic Fibrosis

Genetic condition in which thick, sticky mucus builds up in the body's organs.
Significantly affects the lungs and digestive system.

Pulmonary Function Tests (PFTs)

Measure lung function, including lung volumes and capacities.
e.g., Forced expiratory volume in one second (FEV1), Forced vital capacity (FVC). -Used to diagnose and manage respiratory conditions.

Normal Values/Ranges

Normal values vary by age, sex, height and other factors.
Reference ranges help assess deviation from normal.
