What is the process of moving gas in and out of the lungs?
Ventilation is the process by which air moves in and out of the lungs. Diffusion is the spontaneous movement of gases, without the use of any energy or effort by the body, between the gas in the alveoli and the blood in the capillaries in the lungs.
What is pulmonary circulation and systemic circulation?
Pulmonary circulation moves blood between the heart and the lungs. It transports deoxygenated blood to the lungs to absorb oxygen and release carbon dioxide. The oxygenated blood then flows back to the heart. Systemic circulation moves blood between the heart and the rest of the body.
What is the first step in pulmonary circulation?
Terms in this set (4)
- DeO2 blood leaves the Right Atrium through the tricupsid valve into the right ventricle.
- Right ventricle contracts send DeO2 through pulmonary valve into the pulmonary arteries.
What path does blood take through the circulatory system?
Systemic circulation carries oxygenated blood from the left ventricle, through the arteries, to the capillaries in the tissues of the body. From the tissue capillaries, the deoxygenated blood returns through a system of veins to the right atrium of the heart.
What is the correct order for the flow of blood entering the heart from the vena cava?
Blood enters the heart through two large veins – the posterior (inferior) and the anterior (superior) vena cava – carrying deoxygenated blood from the body into the right atrium. Blood flows from the right atrium into the right ventricle through the tricuspid valve
What is the correct sequence of vessels that blood travels as it leaves the heart?
Blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs. Blood leaves the heart through the aortic valve, into the aorta and to the body. This pattern is repeated, causing blood to flow continuously to the heart, lungs and body
What process allows oxygen to be transferred into the blood from the lungs?
