Study Notes
Blood Vessels
- Arteries, veins, and capillaries are the three main types of blood vessels
- Arteries carry oxygenated blood away from the heart, except for the pulmonary artery
- Veins carry oxygen-depleted blood back to the heart, except for the pulmonary vein
- Capillaries allow for the exchange of oxygen and nutrients with cells
Heart Structure
- The heart has four chambers: left and right atria, and left and right ventricles
- The atria receive blood, while the ventricles pump blood out of the heart
- The septum separates the left and right sides of the heart
Blood Circulation
- Deoxygenated blood enters the right atrium through the superior and inferior vena cavae
- Blood then flows into the right ventricle, which pumps it to the lungs through the pulmonary artery
- In the lungs, oxygen is absorbed into the blood, and carbon dioxide is removed
- Oxygen-rich blood returns to the heart through the pulmonary vein and enters the left atrium
- Blood then flows into the left ventricle, which pumps it out to the body through the aorta
Respiratory System
- The trachea divides into the right and left bronchi, which enter the lungs
- The bronchi branch into smaller bronchioles, which eventually lead to alveoli
- Alveoli are responsible for gas exchange between the lungs and bloodstream
- Oxygen diffuses into the bloodstream, and carbon dioxide diffuses out
Gas Exchange
- Gas exchange occurs in the alveoli, where oxygen diffuses into the bloodstream and carbon dioxide diffuses out
- The exchange of gases occurs through the process of diffusion
Blood Composition
- Blood is composed of red blood cells, white blood cells, and platelets suspended in plasma
- Red blood cells carry oxygen, white blood cells fight infection, and platelets aid in blood clotting
- Plasma carries nutrients, hormones, and waste products throughout the body
