Explanation:
- One of the main differences between adult and fetal circulation is <em>the direction and where the non-oxygenated and oxygenated blood circulates</em>. In adults arteries carry oxygenated blood away from the heart and veins carry non-oxygenated blood towards the heart; in fetuses, arteries carry non-oxygenated blood away from the heart and veins carry oxygenated blood back to the heart.
- Another difference is <em>where does the exchange of gases takes place</em>, in fetuses blood is oxygenated in the placenta, in adults in the lungs.
- The circulation between adults and fetuses differs in <em>where does the pressure increases</em>, in adults is on the left side of the heart, in fetuses on the right side.
- Finally,<em> another important difference between adults and fetuses is the presence of shunts</em>, in fetuses these shunts allow both sides of the heart to work parallelly letting mix blood from both ventricles. This shunt gets closed after birth, so adults do not have them.
I hope you find this information useful! Good luck!
A birds beak helps you identify its habitat by looking at its size and shape. The size and shape will give you an idea of what type of food it eats. A bird will have a beak that is suited for eating food that they find in their habitats such as seeds, nectar, insects, mice or fish. For example, pelicans live close to the ocean. Their beaks are long and they have a pouch in their throat. They catch fish by gulping them out of the water into their throat pouch. If you ever been to Daytona Beach this is a familiar sight. Not something you would see sitting on a park bench in Central Park! Hmmmm <span>sighnoah</span> THANKS!

Answer:
perform functions that tissues cannot carry out on their own
Explanation:
In the hierarchy of living system organs come after tissues and before organ systems. Hence, organs are complex then tissues and perform functions that tissues wont be able to perform on their own.
A organ is made up of various types of tissues. They can be divided into two categories, main tissue and sporadic tissue. Main tissue or parenchyma is unique to that organ and defines the function of the organ. For example: Cortex and medulla together form the main functional tissue in kidney. Similarly, myocardium is the main tissue of the heart. Sporadic tissue has blood vessels, nerves and connective tissues.
