Quiz 22: Being Organized and Steady

Glands are often composed of muscle tissue.

Ligaments are made up of loose fibrous connective tissue.

Blood is classified as connective tissue because of its fluid matrix called plasma.

The urinary system and respiratory system both participate in homeostasis by removing metabolic waste.

To enter the body, substances have to pass through connective tissue cells to reach the tissues beneath.

Homeostasis maintains various levels within a narrow range only if environmental conditions do not fluctuate much.

C) responding only to the internal environment. D) stimulating the body's reproductive organs. E) maintaining a constant level of hormones in the blood.

If your body is dehydrated, the control center in the brain will stimulate the release of a hormone which causes the reabsorption of water into the blood during urine formation.

C) response to external stimuli. D) lack of control over homeostasis. E) a combination of negative and positive feedback.
