1.

When a person is suddenly cut by a sharp object, a nervous impulse is sent along a sensory neuron to the spinal cord. The impulse is immediately transmitted through motor neurons to produce a response. Which of the following correctly identifies and describes this response?

a)

It is a conditioned response that occurs only to prevent injury

b)

It is a learned response that does not occur in infants and small children

c)

It is a reflex response that causes various muscles to contract in order to move away from the object.

d)

It is a voluntary response that is initiated only after the impulse has been carried to the relevant brain area.

2.

An ovum moves from an ovary into the uterine tube where its migration toward the uterus is aided by the peristaltic contractions of the smooth tissues of the uterine tube’s walls.

Part 1 Which body systems are directly involved in the interaction described above?

a)

Circulatory and nervous

b)

Circulatory and immune

c)

Muscular and reproductive

d)

Excretory and nervous

3.

Part 2

Which statement is true?

a)

The nervous system produces hormones that stimulate the ovum, and the circulatory system moves the ovum into the uterine tube.

b)

The circulatory system supplies the uterine wall with oxygenated blood, and the immune system prevents damage to the ovum.

c)

The reproductive system produces the ovum, and the muscular system causes the migration of the ovum by peristaltic contractions.

d)

The excretory system expels the ovum from the ovary, and the nervous system causes the contractions of the smooth tissues of the uterine wall.

4.

Which four body systems interact to allow a person to sneeze?

a)

Muscular, immune, nervous, respiratory

b)

Nervous, respiratory, circulatory, skeletal

c)

Respiratory, endocrine, skeletal, circulatory

d)

Lymphatic, skeletal, respiratory, muscular

5.

Which of the following correctly describes an interaction that occurs between two body systems of a rabbit that helps the rabbit outrun a pursuing coyote?

a)

The skeletal system releases additional calcium, and the circulatory system retains more sodium in the blood to provide muscles with ions for contraction.

b)

The digestive system increases the rate of digestion, and the excretory system ceases to provide tissues with more nutrients.

c)

The respiratory system increases the breathing rate, and the circulatory system increases blood pressure to provide tissues with more oxygen.

d)

The endocrine system releases hormones that prepare the immune system to deal with possible injuries.

6.

A feedback mechanism in the human body is shown.

 

Based on the diagram, which two systems interact to maintain homeostasis?

a)

The nervous and reproductive systems work together to stimulate the production of insulin

b)

The circulatory and endocrine systems work together to keep blood sugar levels constant.

c)

The excretory and nervous systems work together to convert glycogen into glucose.

d)

The immune and circulatory systems work together to circulate blood through the pancreas.

7.

During the gestational period, vital nutrients are absorbed by the digestive system and delivered to the placenta by the circulatory system. The embryo then benefits from these nutrients which are absorbed from the placenta through the umbilical cord. This demonstrates the digestive and circulatory system interacting with the -

a)

Endocrine system

b)

Respiratory system

c)

Integumentary system

d)

Reproductive system

8.

The picture shows bean-shaped glands called nodes. The clusters of cells in nodes include macrophages that break down viruses and other potentially harmful materials. Nodes also contain cells that produce protein particles capable of capturing harmful materials that flow in tissue fluid through the nodes. Different parts of the body are drained by nodes in different regions of the body.

Which body systems are directly responsible for regulating these nodes and protecting the body from harmful materials in tissue fluid?

a)

Immune and lymphatic systems

b)

Digestive and nervous systems

c)

Endocrine and digestive systems

d)

Circulatory and nervous systems
