The relationship between a person’s resting blood pressure and their risk for developing cardiovascular disease is best characterized as:

Use the pull-down menus to insert vocabulary terms into the blanks to make these sentences true: When a blood vessel is breached, [blank1] will adhere to the site of damage and release [blank2].  This signal molecule will stimulate [blank3] in the nearby area to help limit blood loss.

Angiogenesis only occurs under abnormal circumstances, such as the formation of cancerous tumors that require high levels of blood supply.

In the pulmonary circuit, these vessels deliver deoxygenated blood to capillaries in the lungs.

Antibody production is always highest during your first exposure to a pathogen, because on subsequent exposures, B- and T-cells will exist and they make antibodies less necessary for destroying the pathogen.

These cardiac cells have adrenergic receptors on their plasma membrane.

If filtration and absorption are perfectly in balance at a network of capillaries, but edema is occurring in the tissue, which of is the most likely explanation?

How are Natural Killer Cells and Cytotoxic T-cells different?

Use the pull-down menus to insert best vocabulary term or phrase into the blanks to make the following sentences true: In the adaptive or acquired branch of your immune system, you have B cells and T cells.  When a particular clone is exposed to its specific pathogen, it will undergo rapid [blank1].  This process produces effector B-cells, called [blank2], that start to produce many antibodies that circulate in the blood.  Also, at least two kinds of effector T-cells are produced.  One type, called a [blank3], doesn’t generally combat pathogens directly, but rather stimulates and coordinates many other parts of a full-scale immune response.  Finally, if any [blank4] are produced, they will specifically release chemicals into infected cells to kill them and stop the spread of infection.

Study this figure carefully.  The letters shown are indicating time points on the graph to which they are closest.  Use the pull-down menus below it to insert the best terms to make the figure the caption true: This figure shows an action potential in a [blank1] cell of the heart.  At the section just below the “A”, [blank2] causes depolarization from -60 mV towards threshold.  At the point just to the right of the “B”, a rapid [blank3] is occurring and causes the depolarization phase of this action potential.  After these channels close, another set of channels will allow [blank4] during the phase to the left of the “C”, which triggers repolarization of the cell.
