Which procedural term is used to describe 'the scooping out of cancerous skin cells with a curette, followed by destruction of any remaining cells with cauterization'?
- A.
Curettage and Electrodessication
- B.
Cryosurgery
- C.
Excision
- D.
Cryosurgery and Electrodessication
Correct Answer
A. Curettage and ElectrodessicationExplanation
Curettage and electrodessication is the correct answer because it accurately describes the procedure of scooping out cancerous skin cells using a curette and then destroying any remaining cells through cauterization. Cryosurgery involves using extreme cold to destroy abnormal cells, while excision refers to the surgical removal of tissue. Cryosurgery and electrodessication are not the correct terms as they do not fully describe the specific procedure mentioned in the question.Rate this question:

C. The small intestineExplanation
The ileum is the longest section of the small intestine. It is located between the jejunum and the cecum, and it plays a crucial role in the absorption of nutrients from digested food. The small intestine is responsible for the majority of nutrient absorption in the digestive system, and the ileum specifically is involved in the absorption of vitamin B12, bile salts, and any remaining nutrients that were not absorbed in the jejunum.Rate this question:

What does the urinary bladder do?
- A.
Secretes urine
- B.
Stores urine
- C.

Correct Answer
B. Stores urineExplanation
The urinary bladder is responsible for storing urine. It is a muscular organ located in the pelvic region. When the kidneys produce urine, it flows into the bladder through the ureters. The bladder expands as it fills up with urine, and it contracts when it is time to empty the bladder. This storage function allows the bladder to hold urine until it is convenient to release it through the urethra during urination.Rate this question:

- A.
Liver
- B.
Stomach
- C.
Intestines

Kidneys
Correct Answer
A. LiverExplanation
The liver is not part of the digestive system. It is an accessory organ that aids in digestion by producing bile, which helps break down fats. However, the primary organs of the digestive system are the stomach, intestines, and kidneys. The stomach is responsible for breaking down food with the help of digestive enzymes and acids. The intestines absorb nutrients from the digested food. The kidneys, on the other hand, are part of the urinary system and are responsible for filtering waste products from the blood.Rate this question:

The integumentary system consists of the skin, hair, and nails, which are all derived from the same embryonic tissue. The skin is the largest organ of the body and serves as a protective barrier. Hair and nails are both appendages of the skin and have various functions such as insulation, sensation, and protection. However, muscles are not part of the integumentary system. Muscles are part of the muscular system and are responsible for movement and generating force.Rate this question:

Spine
Correct Answer
C. TendonsExplanation
Tendons are not part of the skeletal system. While the skull and spine are bones that make up the skeletal system, tendons are fibrous connective tissues that connect muscles to bones. They play a crucial role in facilitating movement by transmitting the force of muscle contractions to the bones they are attached to. However, they are not considered part of the skeletal system, which primarily consists of bones, cartilage, and ligaments.Rate this question:

The following are part of the Nervous System, EXCEPT:
- A.
Cartilage
- B.
Nerves
- C.
Brain
- D.
Ganglion
Correct Answer
A. CartilageExplanation
The nervous system is composed of various components that work together to transmit signals and coordinate the body's functions. Cartilage is not a part of the nervous system. It is a type of connective tissue that provides support and flexibility to certain parts of the body, such as the joints and the nose. In contrast, nerves, brain, and ganglion are all integral parts of the nervous system. Nerves transmit signals throughout the body, the brain processes and interprets these signals, and ganglia are clusters of nerve cell bodies that help coordinate specific functions.Rate this question:

While they do play a role in regulating blood pressure and producing certain hormones, their main function is to filter waste products from the blood and produce urine. The pancreas, liver, and thyroid gland, on the other hand, are all important components of the endocrine system. The pancreas produces insulin and glucagon, which regulate blood sugar levels, while the liver produces and releases several hormones involved in metabolism. The thyroid gland produces thyroid hormones that regulate metabolism and growth.Rate this question:
