Blood clotting is necessary to heal wounds, but hypercoagulation can cause problems. Which of the following can be caused by hyper coagulation?

Strokes, heart attacks, and pulmonary embolisms

In the cell-mediated immune response, what type of cell helps stop the immune system response after the foreign invaders have been removed from the body?

Suppressor T cells

The mixture of food and digestive enzymes is

chyme

The animal body is organized into systems. Which system involves bone marrow and the thymus?

immune system

What type or types of digestion occur in the stomach, and what processes and chemicals are responsible?

Both mechanical and chemical digestion take place in the stomach. Mechanical digestion occurs due to stomach-churning, and chemical digestion occurs due to pepsin and hydrochloric acid.

What must be absorbed into the bloodstream so that important molecules can get to other parts of the body?

Nutrients

In the process of the digestive system, the pancreas produces enzymes, sodium bicarbonate, and

hormones

What do lymph nodes filter as part of their role in the lymphatic system?

Foreign material

Which term describes the reproductive method of animals like reptiles and birds that lay eggs?

Oviparous

Amphibians have a

three-chambered heart

Digestive enzymes produced by the pancreas are primarily secreted into which organ?

Small intestine

Which tissue contracts to enable movement?

Muscle tissue

There are six types of __________ in the mammalian body. They provide the most range of movement where two or more bones meet.

synovial joints

What are antibodies?

Antibodies are proteins that recognize a specific antigen.

Most vertebrates have a/an __________ made of bone with points of attachment for muscles.

endoskeleton

What do detritivores feed on?

Decaying organisms

Animal cells typically produce energy in the form of __________ through aerobic cellular respiration, which requires oxygen and produces carbon dioxide as a byproduct.

ATP

__________ lines all the surfaces of the body.

Epithelial tissue

Choose the best description of the role of different types of neurons in your body's response to an environment stimulus.

Sensory neurons carry a message to the brain about the stimulus. Interneurons connect sensory neurons to motor neurons. Motor neurons allow the muscles to respond to the stimulus.

What's the definition of specific immune system?

When the body identifies an intruder, it generates more specific immune responses that are unique to that specific invader.
