Human Anatomy And Physiology Quiz

1. What is leukemia?

Too many white blood cells (see pic)

Too many red blood cells

Too many blood clots

Too many platelets

Leukemia is a type of cancer that affects the blood and bone marrow, leading to an overproduction of white blood cells.

Explanation

Leukemia is a type of cancer that affects the blood and bone marrow, leading to an overproduction of white blood cells.

2. What does normal blood look like?

Blue

Green

See Picture

Purple

Normal blood is actually red in color, although the shade may vary depending on the oxygen level. Blue, purple, and green are not colors typically associated with normal blood.

3. What is the main sensory organ responsible for detecting different taste sensations?

Olfactory Nerve

Pineal Gland

Hippocampus

Taste buds are the main sensory organs responsible for detecting different taste sensations such as sweet, sour, salty, bitter, and umami. The olfactory nerve is responsible for the sense of smell, the pineal gland is a small gland in the brain responsible for producing melatonin, and the hippocampus is a part of the brain involved in memory formation.

4. What is the primary function of the cochlea in the human ear?

To control the sense of taste

To regulate balance in the body

To produce earwax

The cochlea is a spiral-shaped, fluid-filled structure in the inner ear that contains tiny hair cells responsible for converting sound vibrations into electrical signals that are sent to the brain for interpretation.

Explanation

The cochlea is a spiral-shaped, fluid-filled structure in the inner ear that contains tiny hair cells responsible for converting sound vibrations into electrical signals that are sent to the brain for interpretation.

5. What is the function of the cochlea in the human ear?

To transport oxygen to the lungs

To maintain balance and spatial orientation

To regulate body temperature

The cochlea is a spiral-shaped organ in the inner ear responsible for converting sound vibrations into electrical signals that can be interpreted by the brain. This process is essential for hearing.

6. What type of muscle is cardiac muscle?

Smooth muscle found in the digestive system.

Skeletal muscle responsible for voluntary movement.

Muscles that control the movement of bones.

Cardiac muscle is a unique type of muscle tissue that is found only in the heart. It is considered involuntary, meaning it contracts without conscious control, unlike skeletal muscle which allows for voluntary movement.

Explanation

Cardiac muscle is a unique type of muscle tissue that is found only in the heart. It is considered involuntary, meaning it contracts without conscious control, unlike skeletal muscle which allows for voluntary movement.

7. What genetic disorder is characterized by abnormal hemoglobin in red blood cells?

Cystic Fibrosis

See Pic

Down Syndrome

Huntington's Disease

Sickle Cell is a genetic disorder where red blood cells form an abnormal crescent shape due to a mutation in the hemoglobin gene. Individuals with sickle cell often experience pain, anemia, and other complications. Down Syndrome, Cystic Fibrosis, and Huntington's Disease are all genetic disorders, but they are not characterized by abnormal hemoglobin in red blood cells like sickle cell.
