Which of the following is not an example of homeostasis?

Maintaining body temperature by putting on a hoodie

When there is a change in the internal body environment, how will the body react to maintain homeostasis by negative feedback?

OPPOSE THE CHANGE.

If you are cold and your body alters the circulation near the skin in order to conserve heat, what characteristic of life is this representing?

REGULATION

Choose the statement that best exemplifies the interrelated nature of anatomy and physiology.

Simple squamous epithelium consists of a single layer of flattened cells, which is appropriate for organs where filtration and diffusion occur.

Which of the following is true of positive feedback?

The change is amplified.

The joint just proximal to the knee is which one of these?

Answer: HIP Proximal refers to the point of attachment closer to the trunk. In this case, "proximal" refers to the hip joint, since the hip is proximal to the knee. The spine is part of the trunk. The ankle is distal to the knee joint, meaning that it is further away from the trunk.

When a blood vessel is damaged, platelets attach and recruit more platelets to the area. These new platelets recruit even more, quickly increasing the number of platelets until the damage is sealed with a blood clot. This amplification is an example of

POSITIVE FEEDBACK.

In terms of anatomic directional terms, the heart is considered ______ to the sternum.

POSTERIOR

Thermoreceptors detect body temperature and send impulses to the brain for analysis. If body temperature is low, the brain will signal skeletal muscles to perform brief, repeated contractions to help generate heat. In this example, what is the effector?

SKELETAL MUSCLES

Homeostasis is best described as

the maintenance of a stable internal environment despite a changing external environment.
