Study Notes
Heart Chambers
- The left ventricle and right ventricle are responsible for pumping blood out of the heart.
Function of the Circulatory System
- Transports oxygen, nutrients, hormones, and waste products throughout the body.
- Maintains homeostasis by regulating body temperature and pH levels.
Role of Arteries
- Arteries carry oxygen-rich blood away from the heart to the body tissues.
- They are muscular and elastic to withstand high pressure from the heart's pumping action.
Blood Oxygen Delivery Process
- After delivering oxygen to cells, blood collects carbon dioxide and other waste products.
- This deoxygenated blood returns to the heart to be re-oxygenated in the lungs.
Blood Flow Direction
- One-way valves within the heart and veins prevent backflow, ensuring blood flows in only one direction.
Non-function of the Circulatory System
- Providing mechanical support to the body is NOT a function of the circulatory system.
Purpose of Blood Vessels
- Blood vessels facilitate the transport of blood throughout the body.
- They include arteries, veins, and capillaries, each serving specific functions.
Order of Blood Flow
- The correct order is: right atrium → right ventricle → lungs → left atrium → left ventricle → body.
Bottom Chambers of the Heart
- The two bottom chambers of the heart are called ventricles.
Interventricular Septum Purpose
- The interventricular septum separates the left and right ventricles, preventing the mixing of oxygen-rich and deoxygenated blood.
