What else can I help you with?
A word meaning toward the wind?
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.
What is the trachea lined hair-like structures called?
The trachea is lined with hair-like structures called cilia. These tiny, finger-like projections help move mucus and trapped particles up toward the throat, where they can be swallowed or expelled. This mechanism is crucial for keeping the airways clear and maintaining respiratory health.
Cilia of the trachea that beat continually propel contaminated mucus where?
toward the throat to be sallowed or spat out
Which cells moves dust particles out of the body?
Ciliated epithelial cells in the respiratory tract play a crucial role in moving dust particles out of the body. These cells have tiny hair-like projections called cilia that beat in a coordinated manner to propel mucus, which traps dust and other debris, upward toward the throat. From there, the mucus can be swallowed or expelled by coughing. This mechanism helps keep the airways clear and protects the lungs from potential irritants and pathogens.
The projections of gray matter toward the outer surface of the spinal cord are called?
Horns
What sweeps mucus down your throat?
Mucus is swept down the throat primarily by the action of cilia, which are tiny hair-like structures on the surface of epithelial cells lining the respiratory tract. These cilia beat in a coordinated manner, moving mucus and trapped particles upward toward the throat, where it can be swallowed or expelled. Additionally, the process of swallowing helps clear mucus from the throat and keep the airways clear.
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.
Where does the cilia of the nasal mucosa move the mucus toward for contaminated mucus?
The cilia of the nasal mucosa move contaminated mucus towards the throat. This movement helps to clear trapped particles, pathogens, and debris from the nasal passages. Once the mucus reaches the throat, it can be swallowed or expelled, thereby helping to maintain respiratory health.
Debris that is trapped in mucus is moved away from the lungs toward the throat by?
cilia
What is a hair like projections that is used to sweep in food and move?
The hair-like projections that sweep in food and aid in movement are called cilia. Cilia are tiny, microscopic structures found on the surface of some cells, particularly in certain protozoa and in the respiratory tract of animals. They beat in coordinated patterns to create currents, helping to move food particles toward the cell or facilitate the movement of the organism through its environment.
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.
How does your throat keep germs away?
The throat plays a crucial role in the immune system by acting as a barrier to pathogens. It contains lymphoid tissues, such as the tonsils, which help trap and destroy germs. Additionally, mucus in the throat helps to trap foreign particles, while cilia (tiny hair-like structures) move these trapped germs toward the mouth, where they can be expelled or swallowed. Together, these mechanisms help prevent infections and keep the respiratory system healthy.
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.
