Study Notes
The Circulatory System
- Transports oxygen, nutrients, and hormones to cells while removing carbon dioxide and waste
- Key parts:
- Heart: Pumps blood
- Blood vessels:
- Arteries: carry oxygen-rich blood from the heart to the body
- Veins: carry oxygen-poor blood back to the heart
- Capillaries: facilitate gas exchange between the blood and surrounding tissues.
- Functions: Provide oxygen and nutrients to the body
- Pulmonary Circulation: Transports blood between the heart and lungs
- Systemic Circulation: Transports oxygenated blood from the heart to the rest of the body.
The Respiratory System
- Facilitates gas exchange by bringing in oxygen and expelling carbon dioxide
- Key parts:
- Nose: Filters and warms air
- Lungs: Main organ for gas exchange
- Alveoli: Tiny air sacs where oxygen is absorbed into the blood and carbon dioxide is released.
- Diaphragm: Muscle that aids in breathing.
Diseases Affecting the Circulatory and Respiratory Systems
- Hypertension (High Blood Pressure) : Increased pressure in the blood vessels often leading to heart disease
- Atherosclerosis: Buildup of plaque in arteries reducing blood flow
- Asthma: Chronic inflammation of the airways, causing difficulty breathing
- Emphysema: Damage to the alveoli in the lungs, leading to shortness of breath
- Stroke: The blood supply to a part of the brain is interrupted or reduced
Prevention Strategies
- Circulatory Diseases:
- Maintain a healthy diet and exercise regularly
- Avoid smoking and manage stress
- Regular blood pressure checks
- Respiratory Diseases:
- Avoid exposure to air pollution and smoking
- Use protective gear in environments with dust and harmful particles
- Practice good hygiene to prevent respiratory infections
Non-Mendelian Patterns of Inheritance
- Codominance: Both alleles are fully expressed in the phenotype (e.g., red and white cow producing roan cow—mixture of red and white)
- Incomplete Dominance: The phenotype is a blend of both alleles (e.g., red and white flowers producing pink flowers).
