The aorta leaves the heart and heads toward, what else, the head.

The heart is made of cardiac muscle and has two side, right and left, which is why it is called a douple pump. Overall the heart has four chambers, two on the left and two on the right.

Your Heart & Circulatory System - Kids Health Heart

The normal heart is a strong, hard-working pump made of muscle tissue. It's about the size of a person's fist.

The heart has four chambers. The upper two chambers are the atria, and the lower two are the ventricles (Figure A). The chambers are separated by a wall of tissue called the septum. Blood is pumped through the chambers, aided by four heart valves. The valves open and close to let the blood flow in only one direction.

From the body to the heart. Figure B below shows dark bluish blood, low in oxygen, flowing back to the heart after circulating through the body. It returns to the heart through veins and enters the right atrium. This chamber empties blood through the tricuspid valve (B) into the right ventricle.

To get to the bottom of this little mystery weneed to talk about the Heart and Lungs.

From the lungs to the heart
After the blood is refreshed with oxygen, it's bright red. Then it returns to the left heart through the pulmonary veins to the left atrium. From there it passes through the mitral valve (D) and enters the left ventricle.

Open circulatory systems (evolved in crustaceans, insects,mollusks and other invertebrates) pump blood into a hemocoel with the blooddiffusing back to the circulatory system between cells.

The Circulatory System Explained - TeachPE

From the heart to the body
The left ventricle pumps the red oxygen-rich blood out through the aortic valve into the aorta (E). The aorta takes blood to the body's general circulation. The blood pressure in the left ventricle is the same as the pressure measured in the arm.

The*descending aorta* goes behind the heart and down the center of the body.

Circulatory System Anatomy, Diagram & Function | Healthline

This circuit takes oxygenated blood from the left side of the heart, around the body. When the blood returns to the right side of the heart, it is deoxygenated, as the oxygen has been mostly used by the muscles and organs in order to make energy.

Heart and circulatory system | Circulatory System | Heart

Cardiac output (CO) is the volume of blood the heart can pump out, usually in litres per minute. CO depends on stroke volume and heart rate. The quicker the heart beats, the higher cardiac output will be as the heart will pump more blood around the body.

The circulatory system consists of the heart, blood vessels and blood itself. Its function is three-fold. Transport, temperature control and protection.
