How do the blood vessels in the flap of skin of a penguin help to keep things warm?
The arrangement of blood flow in the limbs of penguins is that of a counter-current exchange system where the cold blood coming from limbs flows parallel but in the opposite direction then the hot core-temperature blood coming from the heart. As the the hot blood flows outward it re-warms the venous blood which in turns cools down the arterial blood.

What flap made of tissue that prevents blood from flowing backward is?
The flap of tissue that prevents blood from flowing backward is called a valve. Valves are found in veins and in the heart to ensure that blood flows in one direction and does not pool or backflow.
Flap-like lateral wall of each atrium is called the?
A flap-like lateral wall of each atrium is called the auricle. Its purpose is to increase the atrial volume, thereby increasing the efficiency of blood flow into the ventricles.
What is the thin flap of tissue that acts like a one-way door?
These one-way 'doorways' are called valves. They exist in places such as the heart and the oesophagus/stomach opening.
Why do birds flap their wings in place?

What is the epiglottis flap?
The epiglottis is a small, leaf-shaped flap of cartilage located behind the tongue at the base of the tongue. Its main function is to prevent food and liquid from entering the trachea during swallowing by covering the entrance to the windpipe.
How does an elephant use its ears to keep cool?
Elephants have large, thin ears with a network of blood vessels. To cool down, they flap their ears, causing air to flow over the vessels and help regulate their body temperature. This process cools the blood circulating through their ears before being sent back to the rest of the body.

How do eliphants use their ears to keep cool?
they flap them and then they have a nice breeze because they are so big=) CORRECT ANSWER: The tissue in a elephant's ears is very thin with large blood vessels right at the surface. When an elephant is too warm, their overheated blood travels through the large vessels in the ear. By flapping their ears, the surface area cools a bit and excess heat from the blood is released into the air. In this way, the blood is cooled down and then recirculated into the elephants body, helping keep their body temperature down. This cooling strategy is aided by the size of the ears and the speed at which an elephant moves it ears.
What prevents a flap tissue from the blood flowing backwards?
valve
What ways do penguin use their flippers?
