What is the classification of blood in terms of tissue types?

Back

Blood is classified as a connective tissue despite circulating throughout the body.

Front

What is the route for cerebrospinal fluid to reenter the bloodstream?

Back

Cerebrospinal fluid reenters the bloodstream via the arachnoid villi, not the choroid plexuses.

Front

What type of epithelium is formed by a single layer of flattened cells?

Back

Simple squamous epithelium.

Front

What is the term for blood cell formation?

Back

Hematopoiesis, not osteogenesis.

Front

What is the blood pH level in a person with alkalosis?

Back

A person with alkalosis has a blood pH greater than 7.45.

Front

What are the main functions of connective tissue?

Back

Connective tissue supports, binds, and protects other tissues and organs.

Front

What is the primary function of epithelial tissue?

Back

Epithelial tissue covers body surfaces, lines cavities, and forms glands.

Front

What is the role of the choroid plexus in the brain?

Back

The choroid plexus produces cerebrospinal fluid (CSF).

Front

What is the difference between simple and stratified epithelium?

Back

Simple epithelium has one layer of cells, while stratified epithelium has multiple layers.

Front

What is the significance of blood pH in the human body?

Back

Blood pH is crucial for maintaining homeostasis; normal pH ranges from 7.35 to 7.45.
