Which of the following statements is NOT TRUE about tissues?
A. The extracellular matrix of blood tissue is the plasma

C. Epithelial cells sometimes have cilia like the ones used in comb jellies and placozoans
D. Nervous Tissue has only one cell type, the neuron
Which of the following is NOT a mechanism to maintain the body’s internal temperature?
A. Fluid has a high capacity for heat, so it requires a great deal of energy to raise its temperature.
B. Warmed fluids from the body’s surface return to the body’s core, thus heating the body.
C. Fluid acts as a coolant by increasing the blood flow from the warm body core to the peripheral tissue, thus cooling the body.
D. Fluid is evaporated as sweat from the skin’s surface, thus cooling the body.

Interstitial fluid.arrow_forwardWhich of the following is an example of negative feedback? A. High blood sugar will increase the viscosity of blood plasma (plasma is concentrated). In response, water is drawn into the plasma from surrounding tissues in order to dilute the plasma B. Breathing rate increases during exercise to provide more oxygen to muscle cells. Heart rate also increase to increase the speed at which the oxygen is delivered. C.
