The Digestive System, the Immune System and the Reproductive System have common functions because they all do the same thing. They all digest food but in their different ways
In the pulmonary circuit, veins carry oxygen rich blood, and in the systemic circuit, veins carry oxygen poor blood.
<h3>
Pulmonary and Systemic Circuit of the Cardiovascular system</h3>
The Cardiovascular System concerns all relations and interaction with the heart . It consists of
- Systemic circuit
- Pulmonary Circuit
The Systemic circuit is responsible for carrying oxygenated blood away from the heart and pumps it towards the organs and tissues of the body and returns it to back to the heart as deoxygenated blood
While the Pulmonary Circuit carries deoxygenated blood away from the heart towards the lungs and also brings it back as oxygenated blood to the heart again.

The correct answer is A. Type I
Explanation:
In biology, a survivorship curve is a type of graphic that shows the rate of survival of individuals of one species along time. This type of graphics includes three types of curves. The first one or Type I occurs when individuals can survive during the first ages but by the middle and end of life, the survival rate falls. The second one or Type II occurs in species in which survival rate slowly declines as time passes. Finally, in the third curve or Type III, there are species that experience difficulties for surviving at the beginning of life by then survival rate stay the same. In the case of humans, most scientists classified our species in Type I because at early age survival rate is mainly high as only a few percentages of the population dies at a young age, but after middle age and in elderly the death rate sharps and therefore survival rate falls.
