Study Notes
The Human Respiratory System
- Breathing: Mechanism of air or water movement across respiratory structures, essential for respiration. Examples include lungs for air and gills for water.
- Respiration: Involves oxygen delivery to cells for energy extraction from sugars.
- External Respiration: Exchange of oxygen and carbon dioxide occurs in the lungs between air and blood.
- Internal Respiration: Exchange of oxygen and carbon dioxide between blood and body cells.
- Cellular Respiration: Process in cells involving oxygen to break down glucose, generating energy (ATP) and releasing carbon dioxide as a waste product.
- Oxygen Pathway to Lungs: Follows a route: Nose → Pharynx → Larynx → Trachea → Bronchi → Bronchioles → Lungs → Alveoli.
The Human Circulatory System
- Pulmonary Circulation: Transports deoxygenated blood from the heart's right side to the lungs for oxygenation and carbon dioxide removal.
- Systemic Circulation: Delivers oxygenated blood from the heart's left side to the entire body, supplying tissues.
-
Functions of the Circulatory System:
- Delivers oxygen and nutrients to organs and tissues.
- Removes carbon dioxide and waste products.
- Transports hormones and immune components.
Parts of the Circulatory System
- Heart: Pumps blood throughout the circulatory system.
-
Blood Vessels: Comprise three types:
- Arteries: Carry blood away from the heart.
- Veins: Return blood with waste products to the heart.
- Capillaries: Connect arteries and veins for efficient nutrient and gas exchange.
Diseases/Disorders Related to Circulatory System
- Atherosclerosis: Cholesterol plaque buildup in arterial walls, leading to narrowed arteries.
- Stroke: Occurs from blockage in brain arteries, can result from atherosclerosis.
- Coronary Heart Disease: Impaired blood flow to coronary arteries, affecting heart function.
- Hypertensive Heart Disease: High blood pressure due to arterioles constriction.
- Rheumatic Heart Disease: Caused by untreated streptococcal infections leading to heart damage from immune responses.
-
Blood Disorders:
- Hemophilia: Blood fails to clot properly.
- Anemia: Low red blood cell count.
- Leukemia: Increased abnormal white blood cells.
Parts of the Heart
-
Right Side (Deoxygenated Blood):
- Right Pulmonary Artery
- Superior Vena Cava
- Right Pulmonary Veins
- Right Atrium
- Inferior Vena Cava
- Tricuspid Valve
- Right Ventricle
-
Left Side (Oxygenated Blood):
- Systemic Aorta
- Left Pulmonary Artery
- Left Atrium
- Left Ventricle
- Semilunar Valve of Systemic Aorta
