 Part Which of the following statements about the interactions between the circulatory and respiratory systems is/are true? Select all that apply. During exercise, the heart pumps faster and the demand for oxygen decreases. Blood flows from the right side of the heart to the body, then to the left side of the heart and then to to lungs. The ability of oxygen to be carried in the blood is largely mediated by the presence of the protein hemoglobin. The interactions between alveoli and capillaries allow for gas exchange to occur. 

Respuesta :

Each applies To supply the body with oxygen, the respiratory system collaborates directly with the circulatory system.

How do alveoli and capillaries interact?

The alveoli are encircled by capillaries, which are tiny blood vessels. The capillaries and alveoli's thin walls allow oxygen to get from the alveoli to the blood. The capillaries later join the veins, which are bigger blood vessels, to carry the oxygenated blood from the lungs to the heart.

Do capillaries have a gas exchange system?

Each alveolus is closely connected to a network of capillaries that transports deoxygenated blood from the pulmonary artery. Due to the thin alveolar and capillary walls, gases can interchange swiftly via passive diffusion along concentration gradients.
