Respiratory System

The respiratory system includes the lungs and the airway. The questions in this category focus mainly on the anatomical and physiological processes associated with breathing.

What is the end product of anaerobic respiration?

"http://wiki.answers.com/Q/What_is_the_end_product_of_anaerobic_respiration_in_human_being"

Besides energy, you also have lactic acid as a byproduct which is very dangerous if not removed quickly by repaying the oxygen debt.

What is anaerobic respiratory?

A process where, energy is released from molecules such as glucose in food, without requiring oxygen. Anaerobic respiration releases energy fast, although isn't as effecient as aerobic respiration. Simply, it is respiration withour the presence of oxygen.

When can respiratory acidosis occur?

There are multiple issues that can lead to respiratory acidosis, but respiratory acidosis is defined as when the lungs cannot eliminate CO2, which leads to buildup of carbonic acid (traditionally broken down into CO2 and Water in the lungs).

Why is the male larynx bigger than the female larynx?

Because of the genetic factor which is influencing the size of the human body so as larynx,

The opening into the larynx is partially covered by the what?

The opening into the larynx is partially covered by the glottis. When someone speaks, it causes the vocal folds to vibrate.

What does it mean when oxygen moves from the lungs into the bloodstream?

Oxygen is moving by simple diffusion. It is going from a higher level of oxygen (air) to lower (blood).

What are the long-term effects of exercise on the skeletal system?

The skeletal tissue is a 'living' part of your body and so has the ability to repair itself and adapt like almost all the rest of the parts of your body. The long term effects of exercise depend on what type of exercise you are talking about.

Resistance-based exercise such as weight-lifting puts stress on the bones involved in the lifting. Over time this actually triggers an adaptation mechanism that results in bone density increasing and therefore making the bones stronger. This can help prevent/reduce bone wasting conditions such as osteoporosis.

Endurance-type exercise, however, causes wear to cartilage and joint material that is not usually repaired by the body. Worn out joints (particularly knees and hips) can cause problems later in life that may require surgical correction.

How is diffusion used when cells remove carbon dioxide?

Carbon dioxide moves out of the cells from a higher to lower concentration across the cell membrane. Then the CO2 moves through the capillary wall across the diffusion gradient. The diffusion process is repeated at the capillary/alveolar junction.

Is Hyperventilation characterized by slow and shallow breathing?

The word part hyper- means above, beyond, or more than. Therefore hyperventilation means breathing that is faster or more than normal.

How is the respiratory system affected by environmental factors such as smog?

Smoking: lung cancer, cause you to cough grossly and choke

Smog; it will 100% make you sick

Pollen: will cause allergies, sneezing, coughing, itchy eyes and nose, runny nose

hope it helped!!

Where does the CO2 go?

It is brought back to the heart to be pumped through the lungs to be exhaled.

Why is it important to know the function of the respiratory system?

It is in order to have a proper understanding of how our body works. It is also to teach us how to value these organs which are part of our respiratory system.

What determines whether oxygen and carbon dioxide diffuse into or out of the capillaries of the tissues near alveoli explain?

its the blood which act as a transporter and the concentration of blood determines that oxygen will diffuse faster than carbon dioxide due to its small molecular weight but if diffusion occur in such manner then amount of carbon dioxide will be automatically more. carbon dioxide is a toxic gas and its presence in more amount can causes problems by increasing the PH of blood,but carbon dioxide has an affinity for water. The excess carbon dioxide gets dissolve in water or simply we can say in plasma of blood more than oxygen so its its excrete in lungs and passes from lungs to mouth in atmosphere following bronchioles and bronchi.
