Cardiovascular System
Cardiovascular System
The cardiovascular system, also known as the circulatory system, is a complex network responsible for transporting essential substances throughout the body.
Heart: Double Pump
Heart: Double Pump
The heart, a vital organ of the cardiovascular system, is a double pump that circulates blood to the lungs and the rest of the body.
Heart Location
Heart Location
The heart is located in the mediastinum, situated between the lungs. It rests between the second and sixth ribs.

Study Notes
PNA 200 Cardiovascular System
- The cardiovascular system is sometimes called the circulatory system
- It consists of the heart, blood vessels, and lymphatic system
- It's a network for transporting oxygen, nutrients, and removing waste products
- It carries hormones, gases, products of digestion, and immune cells.
Heart as a Metaphor
- The heart is a metaphor for love and courage
- "Heart attack" describes surprise or shock
- Blood is described as running hot or cold in speech and poetry
- Emotions are more about hormones than the heart muscle
Heart Structure
- The heart is surrounded by a sac, the pericardium
- The pericardium has two layers: fibrous and serous
- The wall has three layers: epicardium, myocardium, and endocardium
Four Chambers
- The heart has four chambers: 2 atria and 2 ventricles
- Atria receive blood and pump it into the ventricles
- The ventricles pump blood out of the heart
Heart Valves
- The heart has 4 valves
- 2 atrioventricular (AV) valves (tricuspid and mitral)
- 2 semilunar valves (pulmonary and aortic)
- The valves allow one-way blood flow
- Pressure changes cause the valves to open and close.
Double Duty
- The heart has two pumps: right and left
- The right side pumps blood to the lungs
- The left side pumps blood to the rest of the body
Location
- The heart is about the size of a closed fist
- It's located beneath the sternum, in the mediastinum, between the lungs
- The heart rests obliquely, with the apex (pointed end) pointing towards the lower left, and the top part to the upper right
- Apex is the point of maximal impulse (where heart sounds are loudest)
Coronary Arteries
- Two major coronary arteries supply blood to the heart
- These branch off the aorta
- Branches carry blood to the left and right sides of the heart
Cardiac Veins
- They usually lie alongside the coronary arteries and their branches
- The left and right cardiac venous systems collect deoxygenated blood
- The venae cordis minimae drain the heart muscle directly to the heart chambers
Conditions and Disorders
- Heart valve problems might cause the heart to work harder
- Several factors can cause heart valve conditions, such as aging, birth defects, infections, or underlying conditions like diabetes
- Different types of heart valve problems include: regurgitation (leaky valves), stenosis (stiff valves), prolapse (floppy valve leaflet) or atresia (missing valve).
Heart Beat
- Blood flows into the right atrium from the vena cava, passing through the tricuspid valve to the right ventricle
- Then blood is pumped through the pulmonary valve to the pulmonary artery
- Meanwhile, blood fills the left atrium from pulmonary veins
- Then blood passes through the mitral valve to the left ventricle
- Finally, blood exits through the aortic valve to the aorta.
