alee, means toward the wind.
What is the force that pulls earth toward a person?
gravity
What moves blood toward the heart?
veins or arters
How are depressions symbolized on a topographic map?
A depression is shown by contour lines with small marks pointing toward the lowest point of the depression.
Why would 2 electrons repel?
It has to do with entropy. The law of entropy states that the universe tends toward having the lowest possible energy at every point. Two oppositely charged particles' magnetic fields cancel out, so, to follow this tendency, they attract each other to have more of their fields overlapping, and so, reducing the energy at each point. Two electrons are samely charged, and so, when their fields overlap the energy of each field will add together. To keep with entropy, the particles repel so that less of their fields overlap, making the energy at each point as low as possible.
Cilia of the trachea that beat continually propel contaminated mucus where?
toward the throat to be sallowed or spat out
The projections of gray matter toward the outer surface of the spinal cord are called?
Horns
How does the structure of the uterine tube move the egg toward the uterus?
The uterine tube is lined with cilia. These small hair-like projections sweep the egg toward the uterus.
Debris that is trapped in mucus is moved away from the lungs toward the throat by?
cilia
What do the hairs in the nose and the mucus in the throat accomplish when someone inhales?
The air you breathe is full of tiny particles that have to be filtered out before the air can go into your lungs. The hair in your nose helps stop bits of dust and other debris from passing further into your nose. Further inside, the layer of sticky mucus catches the tiny particles that got through the hairs. The cells in your nose have microscopic hairlike projections on them called cilia. They actually beat back and forth about 16 times a second, and move the layer of mucus toward the back of your nose where it's normally swallowed. If something happens, like a particularly irritating particle gets caught in the mucus, you'll feel a tickle in your nose, triggering your sneeze reflex. It causes you to take in a big breath of air, and forcefully expel it through your mouth and nose, taking some mucus (and hopefully the irritant) with it. The mucus in your throat does the same filtering job, and irritations there cause coughing. The mucus also helps moisten the air, to make it better to breathe into your lungs.
When a beam of alpha particles passes between two electrically charged plates which plate is the beam deflected toward?
The beam of alpha particles is deflected toward the negatively charged plate. This is because alpha particles are positively charged, and opposite charges attract each other.
What is the function of globlet cells and cilia in trachea?
Goblet cells in the trachea produce mucus that helps to trap and remove foreign particles and pathogens from the airways. Cilia are hair-like structures that line the trachea and sweep the trapped particles and mucus up and out of the respiratory system toward the throat to be swallowed or expelled through coughing. Together, goblet cells and cilia help to protect the lungs from harmful substances.
How do the epithelium cells in the windpipe push up dustback up into the throat?
The epithelial cells in the windpipe, which are lined with cilia, wave in a coordinated manner to move mucus along with trapped particles like dust upward toward the throat. This upward beating motion is called mucociliary clearance and helps to remove foreign particles from the respiratory tract, preventing them from entering the lungs.
When a beam of alpha particles passes between two electrically charged plates - which plate is the beam deflected toward?
The beam of alpha particles will be deflected toward the negatively charged plate. This is because alpha particles are positively charged and are attracted to the negative plate.
Can you eat while standing on your head?
Yes. The throat muscles pull food toward the stomach regardless of which way you are positioned.
