Essentials of Anatomy & Physiology Quiz

A living thing, whether one-celled like bacteria, or trillions of cells like humans.

A group of interconnected parts working together to perform a specific function.

The ability of an organism to sense and respond to changes in the environment.

An increase in size, often by increasing the number of cells, cell size, or substance around cells.

The chemical processes that occur within a living organism to maintain life.

The highly organized structure of an organism, from cell organelles to organs.

The ability of an organism to use energy to perform vital functions such as growth, movement, and reproduction.

The ability of an organism to sense and respond to changes in its environment.

The process of change in an organism over time, involving growth and specialization of cells.

The process of cells becoming specialized in structure and function.

The creation of new cells or organisms.

Maintaining a stable internal environment within the body, despite external or internal fluctuations.

Factors that can change within the body, like temperature or chemical content.

Processes that help maintain homeostasis, like sweating or shivering.

The ideal value for a variable in homeostasis.

The range of values for a variable that still allows for homeostasis.

A regulatory mechanism where a change in a variable triggers a response that opposes the initial change, bringing the variable back to its normal range.

A regulatory mechanism where a change in a variable triggers a response that amplifies the initial change, moving the variable further away from its normal range.

The sensors that detect changes in the body's internal environment, such as body temperature or blood sugar levels.

The part of the body that receives information from receptors and initiates a response to maintain homeostasis.

The structures that carry out the response initiated by the control center to maintain homeostasis.

The ability of the control center to integrate responses of multiple effectors to maintain homeostasis.

The process by which the body regulates its temperature, ensuring it stays within a narrow range.

The position of the body standing upright with the face directed forward, upper limbs hanging to the sides, and palms of the hands facing forward.

Lying face upward.

Lying face downward.

Used to describe body parts that are above another.

Used to describe body parts that are below another.

Used to describe body parts that are on the front of the body.

Used to describe body parts that are on the back of the body.

Used to describe structures that are on the same side of the body.

A condition where the body's ability to maintain homeostasis is overwhelmed, leading to a potentially harmful cycle.

A type of negative feedback mechanism where reduced blood pressure triggers an increase in heart rate to restore normal blood pressure.

The inability of negative feedback mechanisms to restore homeostasis, leading to a cascade of worsening conditions.

The delivery of blood to the heart muscle, crucial for its proper functioning.

The state where the heart's ability to pump blood is compromised, potentially leading to a fatal outcome.

Toward the back of the body.

Toward the belly of the body.

Closer to the point of attachment.

Farther from the point of attachment.

Away from the midline of the body.

Toward the middle or midline of the body.

Toward or on the surface.

Away from the surface, internal.
