Answer:
Thematic Apperception Test
Explanation:
Answer:
The answer is B: left and right main bronchi.
Explanation:
The air enters the lungs through the nose and mouth, initially passing through the pharynx, from there the air passes through the epiglottis to reach the larynx (where the vocal cords meet); then continue to the trachea, which is divided into 2 tubes in its lower part, called right and left bronchial (primary bronchi). It ends up in even smaller tubes called bronchioles, as thin as a hair and finally ending, in the alveoli, where the gas exchange occurs.
Pernicious anemia produces red blood cells that are <u>large</u> and<u> vitamin B12</u> deficiency contributes to pernicious anemia.
Explanation:
When there is a lack of intrinsic factor, secreted in the parietal cells of the gastric mucosa or the stomach lining, vitamin B12 absorption from the stomach is affected.
Vitamin B12 is one of the key factors responsible for normal synthesis and maturation of fully functional red blood cells (RBCs).
The main function of the RBCs is to carry oxygen through hemoglobin to all parts of the body. In order to transport oxygen, the RBCs must be mature with normal shape (concave center and circular shape) and size.
When there is a lack of vitamin B12, the RBCs are not matured and immature, megaloblastic, large, irregularly-shaped red blood cells are formed and circulate in the blood. This also leads to macrocytosis of RBCs.
These cannot function as normal mature blood cells because of the irregular shape and cannot carry hemoglobin to transport oxygen.
After the first 12 hours, the body loses about 0.39°C (0.7°F) per hour. than 12 hours. you use the rate of 0.78°C per hour to estimate the time of death. Temperature of dead body is 32.2°C
Answer:
CD4 cells are a type of immune cell found in the human body. These cells protect us from infections. CD4 count is a measurement of the number of CD4 cells in a blood sample. It is also used to monitor the progression of HIV infection.
In an HIV-negative adult, the normal range of CD4 count is 500-1500 mm3.
In AIDS there is the destruction of the blood CD4 lymphocytes by the virus.
Explanation:
CD4 cells are a type of immune cell that is found in the blood. This cell count is a measure of the number of these cells in a milliliter of blood. It is an important indicator of immune health.
When the CD4 count gets lower than 200 mm3 the patient is more prone to get opportunistic infections like rare fungal infections, Tuberculosis, Mycobacterial infections, parasitic infections, etc.
The CD4 count is used to measure to identify an immune deficiency in people.
