Aggregate Function

A function that takes a collection of data and returns a single value. It can be used to summarize data, find a maximum or minimum value, or perform other calculations across a dataset.

Scalar Variable

In programming, a variable that can store a single value. It can be used to store numbers, text, or other data types.

Relational Database

A database system that stores data in rows and columns. It's a popular choice for storing structured data and is commonly used for relational databases.

Relational Database Model

A way to organize data in a database where each table has a unique identifier called a primary key. Relationships are established between tables using foreign keys.

Study Notes

Heart Location

  • Located in the thorax
  • Between the lungs
  • Resting on the diaphragm
  • Within the mediastinum

Heart Anatomy (Detailed)

  • Superior Vena Cava: Receives deoxygenated blood from the upper body
  • Inferior Vena Cava: Receives deoxygenated blood from the lower body
  • Right Atrium: Receives deoxygenated blood from the body
  • Right Ventricle: Pumps deoxygenated blood to the lungs
  • Pulmonary Arteries: Carry deoxygenated blood to the lungs
  • Pulmonary Veins: Carry oxygenated blood from the lungs
  • Left Atrium: Receives oxygenated blood from the lungs
  • Left Ventricle: Pumps oxygenated blood to the body
  • Aorta: The largest artery; carries oxygenated blood away from the heart to the body
  • Valves (Mitral, Tricuspid, Pulmonary, Aortic): Ensure one-way blood flow

Heart Function

  • Pulmonary Circulation: Blood travels from the heart to the lungs, picks up oxygen and releases carbon dioxide.
  • Systemic Circulation: Oxygenated blood is pumped from the heart to the rest of the body, delivering oxygen and nutrients and removing waste products.

Systole and Diastole

  • Diastole: Heart relaxation; ventricular filling
  • Systole: Heart contraction; ventricular emptying

Heart Tunics

  • Endocardium: Inner lining of the heart
  • Myocardium: Heart muscle layer
  • Pericardium: Protective sac surrounding the heart

Electrical Conduction System

  • Sinoatrial (SA) Node: Initiates the heartbeat
  • Atrioventricular (AV) Node: Delays the signal to allow atrial contraction before ventricular contraction.
  • Bundle of His: Conducts the electrical impulse from the AV node to the ventricles
  • Purkinje Fibers: Transmit the signal throughout the ventricles, causing them to contract.

Blood Vessel Structure

  • Arteries: Thick walls, high pressure, carry blood away from the heart
  • Veins: Thin walls, low pressure, carry blood toward the heart
  • Capillaries: Microscopic vessels where gas and nutrient exchange occur

Types of Blood Vessels

  • Arteries (Large and Small):
  • Arterioles: Small vessels leading to capillaries
  • Capillaries: Microscopic vessels for exchange
  • Venules: Small vessels leading from capillaries
  • Veins: Larger vessels returning blood to the heart

Blood Vessel Function

  • Arteries: Deliver blood to the tissues, maintain blood pressure
  • Veins: Collect blood and facilitate return to the heart
  • Capillaries: Facilitates gas and nutrient exchange between blood and tissues
