When the skin comes in contact with an irritant, receptors in the skin send signals to the spinal cord. The signal is then sent to the brain for processing, and the individual begins to scratch the affected area.
Which statement best describes the interaction between body systems that allows the individual to scratch?

Receptors on the integumentary system send signals through the nervous system to cause a response to scratch.

The circulatory system sends blood flow to muscles and the nervous system responds by scratching.

Receptors on the integumentary system signals to the endocrine system which responds by releasing hormones.

The respiratory system speeds up signaling to the integumentary system to scratch.

This question has two parts.

When exposed to cold temperatures, the human body works to maintain a stable internal temperature. Blood vessels near the skin constrict to reduce heat loss, and muscles begin to shiver to generate warmth. The brain also signals the release of hormones that increase metabolism to produce more body heat.

Three-banded armadillos can be found in Bolivia, Brazil, Paraguay, and Argentina. Armadillos are the only mammal covered by a "shell". This shell is different than that of a turtle shell in that the armadillo's shell is made of bony plates covered by thickened, hard skin.
In order to protect themselves from predators, the three-banded armadillo will curl into a ball. This shields their soft underbelly from attacks.
Which body systems assist the three-banded armadillo in protection against predators?
Select TWO correct answers.

The integumentary system is specialized and durable (hardened).

The skeletal system of bony plates serve as a structural shield.

The endocrine system releases hormones to signal the armadillo to curl into a ball.

The nervous system absorbs oxygen needed for escaping predators.

When a child is born, their mother experiences many reactions in response to the labor and delivery. A table describing the response to birthing an offspring is shown.
#
Labor and Delivery (Birthing of an Offspring)
1
Chemical signals release the hormones oxytocin to initiate contractions, endorphins to relieve pain, and adrenaline for alertness.
2
The pelvic bones shift and widen as ligaments relax in response to chemical signals.
3
The uterine muscles contract, pressing the offspring through the birth canal.
4
Stress response signals additional oxytocin production to aid uterine contractions to reduce bleeding.
Which set of statements describes how body systems interact for labor and delivery?

#	Labor and Delivery (Birthing of an Offspring)
1	Chemical signals release the hormones oxytocin to initiate contractions, endorphins to relieve pain, and adrenaline for alertness.
2	The pelvic bones shift and widen as ligaments relax in response to chemical signals.
3	The uterine muscles contract, pressing the offspring through the birth canal.
4	Stress response signals additional oxytocin production to aid uterine contractions to reduce bleeding.

The endocrine system produces hormones to regulate the relaxing of ligaments and pain relief.
The muscular system contracts the uterus to birth the offspring and reduce bleeding.

The endocrine system produces hormones to regulate digestive absorption of nutrients.
The skeletal system shifts pelvic bones to signal the brain of injury.

The skeletal system relaxes ligaments after receiving signals from hormones.
The endocrine system sends white blood cells to the developing offspring.

The muscular system contracts the uterus for birth followed by reduced bleeding.
The circulatory system increases blood flow to the uterus to replace blood loss.

Strep throat is caused by a pathogen (bacteria) known as Streptococcus pyogenes. Whenever someone is sick with strep, white blood cells are transported through arteries to your throat, where they can fight and kill the invading bacteria, stopping the infection from spreading.
How do the two body systems described above interact to keep you from getting sick?

Hormones from the endocrine system send signals to the nervous system to stop the infection.

The white blood cells of the immune system replace the red blood cells of the circulatory system.

The white blood cells of the lymphatic system kill the cells of the respiratory system.

The white blood cells of the lymphatic system are transported through the circulatory system to fight an infection.

The Emerald Jewel Wasp has the ability to enslave cockroaches by stinging their brains and injecting venom into them. The wasp then uses the antenna of the roach to direct its movement into a chamber, where it lays a single egg on the relaxed roach and seals it inside with pebbles.
Which two systems is the Jewel Wasp targeting as it takes control of the cockroach?

Immune and endocrine

Skeletal and nervous

Integumentary and circulatory

Nervous and muscular

Acne vulgaris is a self-resolving skin condition where there is a blockage of hair follicles in the skin. This causes an increase in bacteria. To help prevent an infection, many white blood cells begin to rush to the area, resulting in large, white-appearing pimples.
Which two systems are interacting in this scenario?

Integumentary and lymphatic

Endocrine and digestive

Reproductive and immune

Integumentary and muscular

Which sequence best describes an interaction between the digestive and endocrine systems that helps maintain homeostasis?

Skin is damaged --> Platelets begin to clump --> Bleeding stops

Blood glucose level increases --> pancreas releases insulin --> glucose is absorbed and levels decrease

Body temperature decreases --> Muscles start to shiver --> Body temperature increases

Heart rate increases --> Blood vessels constrict --> Blood pressure increases
