Large auricles refer to the external part of the ear, also known as the pinna, which is notably bigger than average. In anatomy, the term can also pertain to the atria of the heart, specifically the auricles that are the upper chambers receiving blood. Larger auricles in either context can affect function, such as sound collection in the case of the ear or blood flow and heart efficiency in the case of the heart. In some species, large auricles serve specific evolutionary purposes, such as enhanced hearing or thermoregulation.

What is a condition of large auricles?
Macrotia
What do a bat's auricles do and are they movable?
The auricles increases the volume of the atrium, and yes, they are movable.
What do bat auricles do and are they movable?
The auricles increases the volume of the atrium, and yes, they are movable.
What are the ear-like structure that extend from the atria?
The ear-like structures that extend from the atria are the Auricles.
Extensions of the atria?
Auricles
What are the ears called?

Which weed has clasping auricles?
Field bindweed (Convolvulus arvensis) has clasping auricles at the base of its leaves. These auricles wrap around the stem, helping the plant to climb and twine around other vegetation.
What has two auricles and two ventricles?
The heart.
What is the function of auricles in the human body?
The function of auricles in the human body is to increase the capacity of the atria to hold blood, allowing for more efficient filling of the ventricles.
What is the function of the auricles in the heart?
The auricles in the heart help to collect blood and assist in filling the heart chambers before they contract to pump blood throughout the body.
Which is the phase of cardiac cycle in which the auricles contract?
The auricles will contract during the systolic phase of the cardiac cycle. This is one of the numbers that is measured when a patient has their blood pressure taken.
What is the purpose of auricles in the human body?
The purpose of auricles in the human body is to increase the surface area of the atria in the heart, allowing for more efficient blood filling and pumping.
