In clinical practice, we might scrape the arch of your foot with the handle of a reflex hammer. Plantar flexion of the great toe is normal. Dorsiflexion (pointing of the toe upward) is not. But I don't know what the stimulus is in your case.
Picture of congestive heart failure. The heart is a pump that works together with the lungs. The heart pumps blood from the veins through the lungs where oxygen is added and then moves it on to the arteries. This pumping action creates a relatively high pressure in the arteries and a low pressure in the veins.
The heart is comprised of the left and right atria and the left and right ventricles. The atria pump blood to the lungs, where it is oxygenated. The oxygenated blood then retu â¦ rns to the heart, where the ventricles pump it to the rest of the body.he heart is comprised of the left and right atria and the left and right ventricles.
