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 pumps blood with a rhythm determined by a group of pacemaking cells in the sinoatrial node. These generate a current that causes contraction of the heart, traveling through the atrioventricular node and along the conduction system of the heart. The heart receives blood low in oxygen from the systemic circulation, which enters the right atrium from the superior and inferior venae cavae and passes to the right
