The right answer is: aorta to smaller systemic arteries to systemic capillaries to systemic veins to right atrium through the tricuspid valve.
The blood pathway is divided into two circuits, both beginning and ending in the heart.
- Systemic circulation (or general circulation, or "circulation")
It begins in the left ventricle, which through an artery distributes oxygenated blood to organs. Then the blood returns to the right heart (right atrium) through the cellar veins.
Each organ has an afferent vessel, supplying blood, and an efferent vessel carrying non-oxygenated blood.
- The pulmonary circulation (or "small circulation")
It begins in the right ventricle, from where the pulmonary artery sends blood without hematosis to a single organ, the lung. The blood is then oxygenated and returns to the left heart (left atrium) by the pulmonary veins.
The answer is the first one

A good example of endosymbiosis is the mitochondria. Three pieces of evidence that suggest the mitochondria was not an original organelle in cells are:
1. They have their own membranes
2. They reproduce by pinching in half which is very similar if not the same to binary fission of bacteria
3. They have their own genomes which are passed off to the offspring.
