- B. six
- C. eight
- D. ten
Correct Answer: A
Rationale: The human body is composed of four main types of tissues: epithelial, connective, muscle, and nervous tissue. Epithelial tissue covers body surfaces, connective tissue provides support and structure, muscle tissue allows movement, and nervous tissue coordinates body activities through electrical signals. Therefore, the correct answer is four.

Which of the following epithelial types is correctly matched with its major function?
- A. Simple squamous epithelium — secretion or absorption
- B. Stratified squamous epithelium — changes shape when stretched
- C. Stratified squamous epithelium — diffusion
- D. Simple columnar epithelium — secretion or absorption
Correct Answer: D
Rationale: The correct answer is D. Simple columnar epithelium is matched correctly with its major function of secretion or absorption. Simple squamous epithelium is best suited for diffusion due to its thin structure, while stratified squamous epithelium is mainly for protection against mechanical stress and pathogens. Stratified squamous epithelium does not function primarily in diffusion. Therefore, understanding the structure and function relationship of different epithelial types is crucial for correctly identifying their major functions.
Which organ is part of the male reproductive system and urinary system?
- A. Epidermis
- B. Ureter
- C. Testis
- D. Urethra
Correct Answer: D
Rationale: The correct answer is D: Urethra. The urethra is a part of both the male reproductive system, as it serves as the duct for semen during ejaculation, and the urinary system, as it allows the passage of urine from the bladder to outside the body. The epidermis is the outermost layer of the skin, the ureter is a tube that carries urine from the kidneys to the bladder, and the testis is a male reproductive organ responsible for producing sperm.
What is the basic unit of life and the building block of tissues and organs?
- A. Atom
- B. Organelle
- C. Cell
- D. DNA
Correct Answer: C
Rationale: The correct answer is C: Cell. Cells are the basic unit of life and are the building blocks of tissues and organs. They are responsible for carrying out essential functions in living organisms, such as growth, maintenance, and reproduction. While atoms are the smallest unit of matter, organelles are structures within cells, and DNA carries genetic information within cells, the cell itself is the fundamental unit of life.
Which process is increased when the sympathetic nervous system is stimulated?
- A. Uterine activity
- B. Gastrointestinal activity.
- C. Cardiac Output
- D. pancreatic activity.
Correct Answer: C
Rationale:
Which structure is located on the sternum?
- A. Xiphoid process
- B. Sesamoid bone
- C. Hyoid bone
- D. Ossified process
Correct Answer: A
Rationale: The xiphoid process is the structure located at the bottom of the sternum. It is a small cartilaginous process that ossifies with age. The sesamoid bone is a small bone embedded within a tendon, not typically found on the sternum. The hyoid bone is a U-shaped bone located in the neck, not on the sternum. 'Ossified' refers to a structure that has become hardened like bone, but it is not a specific structure located on the sternum.
