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.
hearts have 2 types of chambers: atria and ventricles. Atria are where blood enters the heart and ventricles pump the blood out of the heart. Hearts take in oxygen poor blood, â¦ pump it through the pulmonary circuit (lungs/gills) where it gets oxygenated, and then they pump it out to the rest of the body.
