Describe and explain how blood flows from the foot to the lungs.
Natali5045456 [20]

Answer:

lungs:

The blood first enters the right atrium.

The blood then flows through the tricuspid valve into the right ventricle.

When the heart beats, the ventricle pushes blood through the pulmonic valve into the pulmonary artery.

The pulmonary artery carries blood to the lungs where it “picks up” oxygen.

It then leaves the lungs to return to the heart through the pulmonary vein.

The blood enters the left atrium.

It drops through the mitral valve into the left ventricle.

The left ventricle then pumps blood through the aortic valve and into the aorta. The aorta is the artery that feeds the rest of the body through a system of blood vessels.

Blood returns to the heart from the body via two large blood vessels called the superior vena cava and the inferior vena cava. This blood carries little oxygen, as it is returning from the body where oxygen was used.

The vena cavas pump blood into the right atrium and the cycle begins all over again.

Leona [35]

Answer:

A. First

Explanation:

Linda has some espresso kept in the cup holder in her vehicle. She needs to all of a sudden pummel on her brakes and stop. The cup stayed in the cup holder, yet the espresso sprinkled and spilled all over.

This happens on account of the Newton's first law of movement. It states that that an object at rest will remain at rest until and unless and external force is applied to it for its movement. It also describes the inertia.
