What is the difference between Mechanical and Chemical digestion?
(¿Cuál es la diferencia entre digestión mecánica y química?)

What is the difference between Pulmonary and Systemic circulation?
(¿Cuál es la diferencia entre circulación pulmonar y sistémica?)
Pulmonary Circulation - Pulmonary Circulation is when blood is pumped to the lungs to exchange deoxygenated blood (Lacking Oxygen) for oxygenated blood (Oxygen Rich).
Systemic Circulation - Systemic Circulation is when blood is moved between the heart and parts of the body delivering oxygen, nutrients, and removing waste.

(¿Qué órgano es el órgano digestivo más importante y por qué?)
Small Intestine because this is where most of the digestion and absorption of nutrients takes place.
Describe 3 differences between Veins and Arteries.
(Describe 3 diferencias entre venas y arterias.)
Arteries - They carry blood AWAY from the heart and they are round with thick walls of smooth muscle. Arteries are under HIGH pressure and mostly carry oxygen-rich blood. An exception is the Pulmonary Artery (to the lungs) which carries oxygen-poor blood.
Veins - They carry blood TOWARDS the heart and they are oval-shaped with thin muscular walls. Veins are under LOW pressure and mostly carry oxygen-poor blood. An exception is the Pulmonary Vein (from the lungs) which carries oxygen-rich blood. Veins also have valves to prevent the backward flow of the blood.
Describe an example of a reflex arc reaction.
(Describe un ejemplo de una reacción de arco reflejo.)
When sensory neurons do not send messages to the brain, but instead directly to the synapse in the spinal cord. This allows for faster reflex actions to occur by activating spinal motor neurons without the delay of routing signals through the brain.
