Circulatory system delivers blood (containing oxygen) to cells.
It is the function of the respiratory system to deliver oxygen to the alveoli, where it crosses into the circulatory system, entering red blood cells, and is transported throughout the body. "More" oxygen can be delivered by increasing ventilation, that is, by increased breathing rate, or the volume of each breath. That puts more oxygen at that interface. The Circulatory system can increase the oxygen delivery by increasing heart rate: more blood is pumped through, and so more red blood cells are exposed to the available oxygen. When you are exercising, in a normal, healthy system, both of these happen: you breathe deeper and faster, AND your heart rate (pulse rate), increases. How much each of these happen, and how fast they return to "normal", is both a function of how much work you are doing, and how well conditioned/ trained/fit you are.
The respiratory system functions to bring oxygen into the body and make it available to the cells, and to remove carbon dioxide from the cells and expel it. The cardiovascular system works with the respiratory system by picking up the inhaled oxygen and delivering it to the body's cells, and by taking carbon dioxide from cells and delivering it to the lungs to be exhaled.

The circulatory system carries life-giving blood to the cells. It consists of the heart, blood vessels, and blood, and is responsible for delivering oxygen and nutrients to the cells while removing waste products.

The circulatory system, consisting of the heart, blood vessels, and blood, is responsible for delivering oxygen and nutrients to cells throughout the body. Oxygen and nutrients are transported in the blood and carried to tissues where they are needed for cellular function.

Erythrocytes are red blood cells that have the main function of delivering oxygen to cells in the body. Leukocytes are white blood cells that are associated with the immune system.

Oxygen is transported in the blood by red blood cells. When we breathe, oxygen diffuses into the bloodstream in the lungs and binds to hemoglobin in red blood cells. The heart then pumps the oxygen-rich blood throughout the body, delivering oxygen to all cells via the circulatory system.
The lungs provide oxygen to cells by extracting oxygen from the air we breathe and delivering it to the blood. The blood then carries the oxygen to all cells in the body.

The system that is responsible for delivering nutrients and oxygen and removing wastes and carbon dioxide is actually three different systems. These systems are the respiratory, digestive and circulatory systems.
The circulatory system carries life-giving blood to the cells. It consists of the heart, blood vessels, and blood, and is responsible for delivering oxygen and nutrients to the cells while removing waste products.
The Circulatory System circulates blood throughout the body. This blood has red blood cells that carry oxygen. When you are exercising, your heart beats faster to get more oxygen to the cells. This lets the blood travel faster, delivering more oxygen, which when received by cells is used by the mitochondria (the energy source of cells) to produce energy.
