Where do both digestion and absorption occur in the digestive system?
- A. Stomach
- B. Esophagus
- C. Gallbladder
- D. Small intestine
Correct Answer: D
Rationale: Both digestion and absorption take place in the small intestine. The small intestine is a crucial organ where the breakdown of food into smaller molecules, digestion, occurs with the help of enzymes. This process is essential for the absorption of nutrients, where the smaller molecules are taken up by the bloodstream for distribution throughout the body. While the stomach aids in digestion through the action of gastric juices, the esophagus serves as a tube for food passage, and the gallbladder stores bile produced by the liver to aid in fat digestion. However, neither digestion nor absorption occurs in the stomach, esophagus, or gallbladder, making the small intestine the correct answer for both processes.
Which of the following is classified as a noninfectious disease?
- A. Dengue
- B. Psoriasis
- C. Chikungunya
- D. Brucellosis
Correct Answer: B
Rationale: Psoriasis is classified as a noninfectious disease because it is linked to an overactive immune system that leads to skin inflammation and rapid skin cell growth. Unlike infectious diseases such as Dengue, Chikungunya, and Brucellosis, which are caused by bacteria, viruses, or other pathogens, Psoriasis does not spread through pathogens. Therefore, Psoriasis is the correct choice for a noninfectious disease.
Which of the following proteins is present in blood plasma?
- A. Fibrinogen
- B. Lymphocytes
- C. Monocytes
- D. Platelets
Correct Answer: A
Rationale: The correct answer is A: Fibrinogen. Fibrinogen is a vital protein present in blood plasma that plays a key role in blood clotting. Lymphocytes, monocytes, and platelets are different types of blood cells and not proteins found in blood plasma. Understanding the components of blood plasma, such as fibrinogen, is essential for comprehending its functions in various physiological processes, particularly in clot formation.
What type of tissue largely makes up the pharynx?
- A. Bone
- B. Muscle
