Study Notes
Heart Function and Structure
- The primary function of the heart is to pump blood throughout the body, supplying oxygen and nutrients to tissues while removing waste products.
- The left atrium is the chamber that receives oxygenated blood from the lungs via the pulmonary veins.
- If the heart fails to pump blood effectively, it can lead to conditions such as heart failure, where the body may not receive enough blood to function properly, leading to fatigue, fluid build-up, and serious health complications.
Blood Vessels
- Arteries are the blood vessels that carry blood away from the heart to various tissues and organs throughout the body.
Hydrocarbons
- Hydrocarbons are organic compounds made solely of hydrogen and carbon atoms, serving as the fundamental building blocks of many fuels and chemicals.
- The characteristic feature of hydrocarbons is their ability to form various structures, including chains and rings, depending on the arrangement of their carbon atoms.
- Hydrocarbons typically contain single (sigma) bonds, double bonds, and, in some cases, triple bonds between the carbon atoms.
- The basic composition of hydrocarbons consists exclusively of carbon (C) and hydrogen (H) atoms.
Types of Bonds in Hydrocarbons
- The primary types of bonds found in hydrocarbons include saturated bonds (single bonds) in alkanes and unsaturated bonds (double or triple bonds) in alkenes and alkynes, respectively.
- Hydrocarbons can exhibit a range of bonding structures, which influence their properties and reactivity.
