In the united states, tuberculosis is increasing in frequency due to homelessness and other diseases.
Tuberculosis (TB) is a bacterial infection spread through inhaling tiny droplets from the coughs or sneezes of an infected person. It mainly affects the lungs, but it can affect any part of the body, including the tummy (abdomen), glands, bones and nervous system.
TB is a potentially serious condition, but it can be cured if it's treated with the right antibiotics.
Typical symptoms of TB include:
- a persistent cough that lasts more than 3 weeks and usually brings up phlegm, which may be bloody
- weight loss
- night sweats
- high temperature
- tiredness and fatigue
- loss of appetite
- swellings in the neck
TB that affects the lungs (pulmonary TB) is the most contagious type, but it usually only spreads after prolonged exposure to someone with the illness. In most healthy people, the body's natural defence against infection and illness (the immune system) kills the bacteria and there are no symptoms.
Sometimes the immune system cannot kill the bacteria, but manages to prevent it spreading in the body. You will not have any symptoms, but the bacteria will remain in your body. This is known as latent TB. People with latent TB are not infectious to others.
If the immune system fails to kill or contain the infection, it can spread within the lungs or other parts of the body and symptoms will develop within a few weeks or months. This is known as active TB.

Answer:
Cellular respiration takes place in the cells of all organisms. It occurs in autotrophs such as plants as well as heterotrophs such as animals. Cellular respiration begins in the cytoplasm of cells.
Explanation:
Answer:
70 ml/beat.
Explanation:
Stroke volume may be defined as the volume of the blood that are pumped by the left ventricle in one contraction. The blood output can also be determined by knowing the stroke volume.
The stroke volume can be calculated by the formula as follows:
Stroke volume = End diastolic volume - End systolic volume
Here, end diastolic volume = 120 and end systolic volume = 50.
Stroke volume = 120 - 50
Stroke volume = 70 ml/ beat.
Thus, the answer is 70 ml/ beat.
