True or false: Anatomy is the study of the internal and external body structures, and their relationships to one another?

True or false: Physiology studies the function of body structures?

True or false: Gross (macroscopic) Anatomy studies structures that are too small to be seen with the naked eye?

True or false: Microscopic Anatomy studies structures that are too small to be seen with the naked eye?

True or false: Tissues are groups of structurally similar cells with a common function?

True or false: Organs are composed of two to four tissues that work together to perform one or more specific functions?

True or false: Organ systems are related organs working together to perform a common task?

The cell membrane is selectively permeable to molecules inside the body.

The cell membrane divides intracellular fluid (ICF) from extracellular fluid (ECF).

The cell membrane is made up of a phospholipid bilayer.

The 'heads' of the phospholipids in the cell membrane are hydrophilic.

Cholesterol adds stability to the cell membrane.

The 'tails' of the phospholipids in the cell membrane are hydrophobic.

Integral proteins in the cell membrane can span the membrane completely.

Peripheral proteins in the cell membrane are attached to transmembrane proteins.

Membrane carbohydrates (glycocalyx) are only found on the inner surface of the cell membrane.

True or false: The respiratory system supplies blood with O2 and removes CO2.

True or false: The pH balance in the body is maintained by the respiratory system.

True or false: The structural organization of the body is a hierarchy, with each level containing those below it.

True or false: Atoms are composed of a nucleus containing protons and electrons.

True or false: Elements are electrically neutral, with the number of protons equal to the number of electrons.

True or false: Ionic bonds involve the sharing of electrons between atoms.

True or false: Water is the most abundant compound in cells, making up 60-80% by volume.

True or false: Acids and bases are electrolytes that play a critical role in maintaining the pH balance of cells, organs, and blood within narrow ranges.

True or false: A pH of 7.0 is neutral.

True or false: A solution with a pH of 5 has a higher H+ concentration than a solution with a pH of 6.

True or false: Carbohydrates are composed of carbon, hydrogen, and oxygen atoms.

True or false: Proteins are the primary structural material of the body.

True or false: Lipids are insoluble in water.

True or false: DNA stores the 'blueprint' of an organism and carries out instructions for protein synthesis.
