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 a muscle. It has four chambers that pump blood. The upper two chambers are called the atria and the lower two chambers are called the ventricles.. The heart is really two pumps that work together to move blood through the body.The right-sided pump fills with blood returning from the body and pumps it to the lungs to receive oxygen.This right-sided pump is a thinner muscle than the left-sided pump because it only has to pump blood to the lungs. The left side of the heart receives blood from the lungs and pumps it out to all parts of the body.he heart is a muscle. It has four chambers that pump blood. The upper two chambers are called the atria and the lower two chambers are called the ventricles.. The heart is really two pumps that work together to move blood through the body.
