Question

difference b/w in (parameter) auricles and ventricles

Answer 1

1. The atria stand for the upper chambers of the heart, while the ventricles are the lower chambers.
2. Atria act as receptors of deoxygenated blood, while ventricles receive blood from the left atria and force it into the aorta.
3. Atria have strictly to do with the inner chambers of the heart, while ventricles may even refer to the interconnected brain cavities.
4. The walls of the atria are thinner with low blood pressure, while those of the ventricles are thicker with high blood pressure.

Answer 2

hi mate

here's your answer

Auricle

Auricle refers to a structure of the atrium of the heart, resembling an earlobe. The mammalian heart consists of two atria as right atrium and left atrium. An auricle is attached to the anterior surface of the outer wall of each atrium. Thus, two auricles present in the heart. It can be visualized as a wrinkled, flap-shape structures on top of the heart. The main function of the auricle is to increase the capacity of the atrium. The auricles are anatomically important as other structures of the heart.

Ventricle

Ventricle refers to the two lower chambers of the heart. Ventricles are more muscular than the atria or auricles of the heart. Hence, they have thicker walls as well. The main function of ventricles is to pump blood to the corresponding parts of the body with a high pressure. The more muscular walls of the ventricles help to increase the pressure of blood. Some invertebrates have a single ventricle in their heart while most vertebrates have two chambers in their heart as right ventricle and left ventricle.
