And the ventricle.
The heart is the organ that has two atria and one ventricle.
Yes, upper two chambers of heart are called auricles or atria (singular: atrium).
The Atria and Ventricles are parts of the heart not the blood. The Atria is the upper chambers of the heart and the Ventricles are the lower chambers of the heart.
The heart is divided into four compartments. The two upper portions where blood enters the heart from the body and lungs are the atria. Deoxygenated blood enters the right atrium, and oxygenated blood from the lungs enter the left atrium.
The heart only has one aorta. The aorta is the body's main artery that connects the heart to the body. There is the pulmonary artery but this one only takes blood away from the heart to the lungs. This one aorta carries blood around the body in a circle((from the heart to all organs and back again)) and has extensions that supply each organ and tissue and cell with oxygen and nutrients.
The heart is divided by a partition or septum into two halves. The halves are in turn divided into chambers. The upper two chambers of the heart are called atria and the lower two chambers are called ventricles. The atria receive blood returning to the heart from the body and the ventricles pump blood from the heart to the body. Valves allow blood to flow in one direction between the chambers of the heart.
Septum
In turtles, the heart has two atria and a single ventricle partially divided by a wall of tissue called a septum. In crocodiles, there are two atria and two separate ventricle.
Septum. Between the two atria is the Atrial Septum and between the two ventricles is the Ventricular Septum.
2, the atria is the upper chamber of the heart. since there is alower and upper chamber in the heart, and the upper part is the atria, do the math: four chamber divided in half (two lower and two upper and 2+2=4) equals two which gives the the number of atria!
it is located in the heartThe Atria (plural) or Atrium (singular) are the chambers located in the top of the heart. Below the Atria are the Ventricles.There are two atria in the heart, the left atrium and the right atrium.Atria are located in the heart.
They are the two upper chambers of the heart
These are the atria - there are two in the heart.
salamanders have a heart with one ventricle and two atria
Frogs have two atria just as humans do.
