Exam 32: Homeostasis and the Organization of the Animal Body

The digestive and respiratory tracts contain_________ muscle.

Which of the following controls the temperature in endothermic animals?

Which tissue contains large amounts of densely packed collagen fibers that run parallel to each other?

What characteristics of stratified epithelium make it suitable as an external covering?

Epithelial tissues are attached to the underlying tissue by a noncellular protein layer called the_________ membrane.

The common garter snake (Thamnophis sirtalis) is found throughout North America. In the South, it is active year round. In the North, it is active during the warmer months but hibernates during the winter. It is commonly found basking on warm rocks during cool mornings. This lifestyle indicates that the snake is probably

The extracellular matrix in dense connective tissue contains large amounts of calcium, which causes the tissue to harden and become solid.

Because of the freezing temperatures of the deep ocean, all deep-sea fish must be endotherms.

Why do neurons need glial cells?

This tissue is

Hormones are secreted by exocrine glands directly into a body cavity or onto a body surface, rather than being transported by the blood.

After eating a large meal of pasta, an individualʹs blood sugar levels are elevated. In response to this, the pancreas secretes a hormone called insulin, which acts to lower blood sugar levels. Once the blood sugar levels drop to the normal level, the pancreas stops secreting insulin. This is an example of

The mucus that traps dust particles in the lungs is produced by

Which tissues are found in a sample of skin?

The matrix in cartilage is made of protein fibers called_________ .

What characteristic defines muscle tissue?

Blood is a type of connective tissue that contains fibers and cells suspended in a_________ matrix.

The lining of the respiratory system is composed of _________ tissue.

Most of the homeostatic functions in the body are regulated by positive feedback loops.

An endotherm uses_________ feedback loops to maintain homeostasis.
