Which of the following would not be lined by peritoneum?

Heart ( is not lined by peritoneum since it is located within the thoracic cavity, while peritoneum only lines the abdominal cavity. )

In what phase of mitosis do the chromosomes duplicate?

Interphase

The cell membrane functions to

-Maintain the wholeness of the cell

-Control the entry and exit of various substances.

-Provide a barrier to water-soluble substances

Identify the phases of mitosis

Anaphase (is the stage where sister chromatids are pulled apart to opposite poles of the cell.)

The anaphase of mitosis involves centromeres separating and duplicate parts of chromosomes becoming separated.

True

The _____ is the organelle that plays a complex function in cell reproduction.

Centrosome

The two major components of the cell membrane are

Lipids and Proteins

Which is the correct order of mitosis

Interphase, prophase, metaphase, anaphase, telophase

During the metaphase of mitosis, chromosomes line up between the two centrioles.

True

Filtration is defined as the movement of molecules through a membrane

by hydrostatic, or blood, pressure that is greater on one side of the membrane than on the other.

A factor that increase the rate of diffusion is

-Distance involved

-Concentration of the substance.

-Weight of the molecules

The function of the nucleus is to

Direct the activities of the cell

The orbital cavity would contain the

Eyes

Match the number with the cell part:

1. Endoplasmic Reticulum

2. Mitochondrion

3. Nucleus

4. Golgi apparatus

Identify the body area

Antecubital

Match the membrane with the area it is found

Visceral Pericardium- Adheres to the heart muscle

Visceral pleural- Adheres to the lungs

Parietal peritoneum- Adheres to the abdominal wall

An isotonic solution

-Contains the same concentration of solute particles as a cell

-Has water entering and leaving a cell in equal amounts,

-Has the same osmotic pressure as the cells in the solution

A 0.85% solution of glucose is isotonic to human cells.

False

Cells lose water when placed in which of the following solutions?

Hypertonic

A 5% solution of glucose is isotonic cells.

False

The heart lies specifically in the ——- space.

Mediastinum

The central abdominal area is the _____ region.

umbilical

Cytoplasm occurs between the cell membrane and the nuclear envelope of a cell.

True

Smooth endoplasmic reticulum has a significant function in protein synthesis.

False

Identify the body area

Cephalic

The _____ membranes surround the lungs.

Pleural

What happens to a red blood cells if place in solution A?

Remains normal

A factor that increases the rate of diffusion is

-Distance involved

-Concentration of substance

-Weight of the molecules

A hypertonic solution

-Has a greater concentration (number) of solute particles than do the cells in the solution.

 

-Would cause cells in the solution to lose water or become shrunken.

 

-Has a greater osmotic pressure than do the cells in the solution.

Identify the body part

Inguinal

Identify the body part

Antebrachial

Identify the body area

Acromial

The _____ functions as a sac-like or tubular network of structures that provides transport.

The _____ is the source of most of the cellular energy.

mitochondrion

Which of the following organelles have their structure and function correctly described?

Lysosome-membranous sac; contains enzymes capable of digesting substances

The structure of the nucleus can be described as

Enclosed in a nuclear envelope

Mitochondria function to manufacture proteins.

False

What is another name for a frontal section?

Coronal

What occurs if a red blood cell is placed in a hypotonic solution?

The cell will swell and may eventually burst

A hypotonic solution

-The cells in the solution have a lower concentration (number) of solute particles than the cells.

 

-Would cause cells in the solution to gain water.
