The rectum is imferior. Its important to b mindful of what goes n yout mouth, as whatever enters goes through your system, benefits it or destroys it then eventually passes through the rectum.
Through nose.
I am pretty sure it enters through the artery
In the breathing system, the air enters at the nostrils (nares), passes through the nasal cavity (where some smell detectors are located) , and enters the trachea.Side branches of this system the Eustachian tubescommunicate with the middle ear to allow for the balancing or air pressure across the eardrum.This is the bit that if blocked, can cause you trouble when you have a cold, or when you are flying.
Blood transports glucose through our nerve system and also through the red blood cells.Glucose is transported to the cells by a uni porter. It passes through the erythrocytes membrane (red cell membrane) and as soon as it enters, it is turned into a chemical and/or a source for energy.
Oxygen enters through the nose but is involved with the Respiratory System.
Blood passes through the circulatory system.The lymph fluid is what runs through the circulatory system. This is blood that runs through the system.
No,Blood enters the excretory system though a artery.-Julie.

The respiratory system.
If it passes close enough, it will get into an orbit around Jupiter and may eventually collide with it.
Through nose.
Air enters the the respiratory tract through either the nose or mouth.
Yes it does. The nose is designed with conchae or turbinates that provide a pathway, meatus, that causes the air to touch the walls as it passes through. The nasal cavity is highly vascular, hence nose bleeds, that warm the air as it passes by.
they are called the cells
