Study Notes
Cardiovascular System Functions
- Capillaries play a crucial role in helping to control body temperature.
- Arteries are responsible for carrying oxygen-rich blood to capillaries.
- The aorta is the primary vessel that pumps blood out of the heart to supply the body.
Respiratory System Pathway
- Air enters the body through the nose and subsequently moves through the pharynx and larynx.
- Both mouth and nasal passages serve to warm and moisten the inhaled air.
- The larynx is anatomically connected to the trachea, facilitating air passage to the lungs.
Blood Composition and Function
- White blood cells do not cause clotting; their main role is to combat infections.
- The cardiovascular system is termed 'closed' as blood circulates without entering or leaving the system through openings.
- The right ventricle is responsible for transporting deoxygenated blood to the lungs, not oxygenated blood.
Lung Anatomy
- Each lung receives oxygen supply through separate bronchi.
Cellular Processes
- Cells utilize diffusion for the exchange of nutrients and waste products.
Conditions Affecting Blood Oxygenation
- Anemia is a condition that reduces the blood's capacity to carry oxygen, often characterized by low hemoglobin levels.
Heart and Artery Functionality
- Both the heart and arteries synchronize their contractions to ensure effective blood circulation throughout the body.
Blood Plasma Composition
- Plasma constitutes approximately 55% of total blood volume, serving as the liquid medium for blood cells and nutrients.
