In normal blood the pH is 7.35-7.45, the partial pressure of carbon dioxide is 35-45 mm Hg, and the bicarbonate ion concentration is 22-26 mEq/L. If a patient has a blood pH of 7.5, a partial pressure of carbon dioxide of 47 mm Hg, and a bicarbonate ion concentration of 34 mEq/L, which of the following is most likely the cause:

Select one:

A. respiratory alkalosis

B. metabolic alkalosis

C. metabolic acidosis

D. respiratory acidosis

Answer 1

1 )   

A. 4, 2, 1, 3

• Pulmonary ventilation is a process of air flowing into the lungs during inspiration (inhalation) and out of lungs during expiration ( exhalation).It is the first step to occur during respiration.
• Then occur External Respiration, it is a process of diffusion of oxygen into blood from alveolar air.
• The oxygen and carbon dioxide are transported in different fors through blood to reach into tissue and lung.
• Finally internal respiration occur , where gas exchange occur between blood and tissue, and metabolic reaction occur.
• All other options are wrong because of incorrect sequence.

2)

A. Greater vestibular gland

• It is also called Bartholins gland.
• It is a two pea sized compound alveolar gland.
• They secrete mucus and lubricate the birth canal.
• It is homologous to bulbourethral gland.
• option B is wrong because ,  seminal gland produce majority of fluid of sperm.
• Option C is wrong , because prostate gland secrete prostate fluid , one of the component of sperm.
• Option D is wrong, because Bulbo-urethral gland add fluid into semen during ejaculation.

3)

A. Receiving plasma from a COVID-19 survivor :: artificially acquired passive immunity

B. Receiving a vaccine :: artifically aquired active immunity

• Artificially acquired passive immunity refers to the injection of antibody containing serum or immunoglobulin from another person or animal .COVID-19 survivor will have antibodies in their serum , which give immunity to others.
• artifically aquired active immunity refers to immunization with antigen.Main examples are vaccines.There will be killed or attenuated microbes in the vaccines.
• Option C is wrong beacuse it is an example of naturally acquired active immunity.
• Option D is wrong , because it is a type of passive type of immunity.

4)

True

• Short reflexes to the digestive system produce shortcut for enteric nervous system to act quickly and effectively
• Long reflex to the digestive system involve sensory neuron that send external and internal digestive information to the brain.
• The enteric nervous system can act as a fast, internal response to digestive stimuli. When this occurs, it is called a short reflex.
