Describe blood flow and gas exchange within the heart, circulatory system, and lungs

Answers

First, oxygen enters through the nose to the way to the lungs. In the lungs, there are these grape-like parts called alveoli wherein the exchange if gases occurs. Nerves will deliver the oxygen from lungs to heart. Heart will pump the oxygen with blood through blood vessels throughout the body until it goes back to the heart.
First!..it goes to the superior vena cava..enters to the ventricles and atriums and goes out to the aorta

Superior/Inferior Vena Cava

Right Atrium

Tricuspid valve

Right Ventricle

Pulmonary Valve

Pulmonary Artery

Lungs

Left Atrium

Left Ventricle

Aorta

Rest of body

Gas exchange between tissues and the blood is an essential function of the circulatory system. In humans, other mammals, and birds, blood absorbs oxygen and releases carbon dioxide in the lungs. Thus the circulatory and respiratory system, whose function is to obtain oxygen and discharge carbon dioxide, work in tandem.

Explanation:

Circulatory system

It carries oxygen from the air we breathe to cells throughout the body. The pumping of the heart drives this blood flow through the arteries, capillaries, and veins. One set of blood vessels circulates blood through the lungs for gas exchange. The other vessels fuel the rest of the body.

Blood from the heart flows through these capillaries and collects oxygen from the alveoli. At the same time, carbon dioxide passes out of the capillaries and into the alveoli. When you breathe out, you get rid of this carbon dioxide. The bright red, oxygen-rich blood is returned to the heart and pumped out to the body.

Explanation:

Blood flow: from superior vena cava and inferior vena cava to left atrium to left ventricle to pulmonary artery to lungs (alvioli-where exchange of gas takes place) to pulmonary vein to right atrium to right ventricle to aorta to all parts of the body. circulatory system: has 3 main parts:heart, blood vessels, blood.

Explanation:

:)

Breathing takes place when we inhale and exhale. when we inhale, the oxygen comes in and the circulatory system circulates it to all parts of the body. when you exhale, the carbon dioxide goes out.
