As cells metabolize nutrients, they produce carbon dioxide as a waste product, which diffuses into the blood and is transported back to the lungs for exhalation. Oxygen Delivery and Carbon Dioxide Removal Gas Exchange Dynamics One of the most critical cardiovascular system major functions is the delivery of oxygen to tissues and the simultaneous removal of carbon dioxide.
Oxygen Transport by Red Blood Cells and the Vital Role of Hemoglobin
For instance, adrenaline released during stress triggers changes in heart rate and blood flow to prepare the body for action. Plasma, the liquid component of blood, holds onto water and salts that help regulate osmotic pressure.
Conversely, in cold conditions, vasoconstriction reduces blood flow to the surface, conserving heat in the core. This system operates as the primary transport highway, ensuring that essential nutrients, oxygen, and hormonal signals reach their destinations while efficiently removing metabolic waste.

This internal logistics network ensures that resources are allocated where they are most needed. Immune Defense and Hemostasis Another crucial role within the cardiovascular system major functions is the facilitation of immune defense.
