What statement best describes blood flow through the pulmonary veins?
Which statement best describes blood flow through the pulmonary veins? Pulmonary veins carry oxygen-rich blood from lung capillaries to the heart.
What is the main function of the pulmonary circuit view available hint S?
Figure 1. The pulmonary circuit moves blood from the right side of the heart to the lungs and back to the heart. The systemic circuit moves blood from the left side of the heart to the head and body and returns it to the right side of the heart to repeat the cycle.
What is the main function of the pulmonary circuit quizlet?
The pulmonary circuit carries deoxygenated blood away from the heart to the lungs and returns oxygenated blood back to the heart.
What is found only in arteries?
Which of these features is found only in arteries? Elastic membranes (internal and external) are found in arteries to help absorb the shock of the heart beat and return the vessel to its natural size.
How do the heart and lungs work together?
The heart and lungs work together to make sure the body has the oxygen-rich blood it needs to function properly. The Pulmonary Loop The right side of the heart picks up the oxygen-poor blood from the body and moves it to the lungs for cleaning and re-oxygenating.
What is the correct order of blood flow for the pulmonary circuit?
Pulmonary circulation is ordered from the right ventricle to the pulmonary arteries, through the lungs, to the pulmonary veins, and reenters the heart in the left atrium.
How do veins prevent backflow?
Veins contain a series of one-way valves. As the vein is squeezed, it pushes blood through the valves, which then close to prevent backflow. Venous valve: Venous valves prevent back flow and ensure that blood flows in one direction.
Does increased blood pressure increase blood flow?
Increased pressure in the veins does not decrease flow as it does in arteries, but actually increases flow. Since pressure in the veins is normally relatively low, for blood to flow back into the heart, the pressure in the atria during atrial diastole must be even lower.
