Answer:
The correct answer is c. 12.5
Explanation:
Human pharynx is about 12.5 cm long and is divided into three parts nasopharynx, oropharynx and laryngopharynx. It starts from behind the nose joins to the food pipe(oesophagus). It provide passage for food and air.
Nasopharynx: It makes the upper part of pharynx which connects nose to mouth. Nasopharynx is separated from oropharynx by a soft palate present behind the nose. Nasopharynx helps in breathing.
Oropharynx: The middle part of pharynx is called oropharynx. Our oral cavity descends into it and tonsils are present either side of it. It helps in movement of food from mouth to oesophagus.
Laryngopharynx: It is the lower part of pharynx and opens into the food pipe and it also guide air into the larynx.
Answer:
The presence of spotting, or some bleeding, during the first trimester of a pregnancy, is normal, as the placenta attaches itself on the uterine wall. However, there must never be severe bleeding, or pain. In the case of Mary Healy, she is presenting severe bleeding at her 3rd month of pregnancy, to the point that she has had 4 sanitary napkins used in an hour. Therefore, the doctor will have to:
a) The doctor will be concerned about three possible scenarios: the first, a miscarriage, which often happens during these first three months of pregnancy, and come with heavy bleeding depending on the type of miscarriage. The second scenario, is an ectopic pregnancy, which is a very serious case that requires emergency intervention. The third is infection, which could have caused a possible abortion.
b) The blood type that can be given to Mary Healy in an emergency situation is a complete packed red blood cell transfusion of O Rh negative type. This type is called the universal donor an it is because it is the least likely to cause an immune response from the host, when transfused.
c) The tests performed in blood work for women who present heavy bleeding during the first trimester of their pregnancy include the blood type to see if there is incompatibility, and also to evaluate the levels of pregnancy hormones. The blood type tests will also allow to know the reaction of the body to multiple transfusions, and there will possibly be a test for blood clotting factors.

Explanation:
The anaerobic glycolytic system has 10 steps but they happen very fast. The end product is pyruvate but it turns into lactate almost immediately. Pyruvate turns into lactate so quickly that some refer to this system as the lactic or lactate system.
Answer.
b). False.
Explanation.
Kidneys are responsible for urine formation that helps in removal of waste materials from the body. Urine formation involves three steps, filtration, reabsorption, and secretion.
During filtration, kidneys filter blood and collect water, glucose, amino acids, urea, and various slats and ions. Proteins and red blood cells are not filtered by the process of filtration. As glucose is important for body, it is reabsorbed by the body along with some other substances. Hence, red blood cells, proteins, and glucose are not secreted into the filtrate.
Thus, the given statement is 'false.'
