Which sequence best describes an interaction between the digestive and excretory systems that helps maintain homeostasis?
quence best describes an interaction between the digestive and excretory systems that helps maintain homeostasis?
Food is broken down into glucose → Glucose is stored in the kidneys → Blood sugar rises
Proteins are digested → Amino acids are excreted immediately → No nutrients are absorbed
Nutrients are absorbed into the blood → Wastes move to the kidneys → Wastes are removed in urine
Water is absorbed in the stomach → Pancreas releases enzymes → Water is excreted as feces
Nutrients are absorbed into the blood → Wastes move to the kidneys → Wastes are removed in urine

Breaking down and eliminating waste from food involves several body systems. A student made a partial list of the processes that occur, as shown below.
Muscles in the stomach contract to help break down food.
Nutrients absorbed in the small intestine move into the bloodstream and are transported to cells.
Which body system is interacting with both the muscular system and the circulatory system in these processes?
Digestive
Which characteristic is NOT a defining feature of animals?
Eukaryotic cells
Heterotrophic nutrition
Presence of cell walls
Multicellular organization
Presence of cell walls
How does the digestive system interact with the reproductive system during pregnancy?
It produces hormones for fetal development.
It provides energy to the growing fetus.
It filters blood for the fetus.
It contracts to aid in childbirth.
It provides energy to the growing fetus.
What role does the muscular system play in the process of childbirth?
It produces hormones to initiate labor.
It contracts to push the baby through the birth canal.
It absorbs nutrients for the fetus.
It filters blood to remove waste products.
It contracts to push the baby through the birth canal.
How does the endocrine system maintain homeostasis?
By releasing hormones
Serves as a barrier against infection and injury, and helps maintain homeostasis through sweat glands; includes skin, hair, and nails is the ____
Helps protect the body from pathogens; includes white blood cells, lymph nodes, and spleen is the ___
Integumentary system
Immune system
How do the nervous and integumentary systems interact when you feel an itch from a mosquito bite?
The nervous system sends signals to the skin to produce more melanin.
Sensory receptors in the skin send signals to the brain.
The skin releases hormones to alert the nervous system.
The nervous system increases blood flow to the skin.
Sensory receptors in the skin send signals to the brain.
Why are the lungs considered part of the excretory system?
They excrete carbon dioxide.
How do the respiratory, muscular, and circulatory systems work together during a marathon?
The respiratory system provides oxygen to the blood, which is then delivered to muscles.
What is the goal of successful body system interaction?
Homeostasis is maintained.
Which human body system helps regulate growth, metabolism, and hormone levels throughout the body?
Endocrine
Why is homeostasis important for animals?
It maintains a stable internal environment.
Which two body systems must directly interact for vertebrate organisms to exchange gases?
Circulatory and respiratory
How does the circulatory system help regulate body temperature?
By producing sweat to cool the body and shivering to warm the body
By sending electrical signals to the brain to process information and control temperature
By dilating blood vessels near the skin to release heat and constricting them to retain heat
By increasing oxygen delivery to muscles during exercise
By dilating blood vessels near the skin to release heat and constricting them to retain heat
Which systems interact when a person sneezes?
Digestive and urinary
Immune and respiratory
Endocrine and reproductive
Skeletal and muscular
Immune and respiratory
The endocrine and reproductive systems interact to regulate important processes in human reproduction.
Which statements best describe an interaction between the endocrine and reproductive systems?
Select TWO correct answers.
The endocrine system releases hormones that trigger menstruation when fertilization does not occur.
The reproductive system stores and releases hormones that control blood sugar levels.
The endocrine system sends electrical signals that cause uterine contractions during labor.
The endocrine system produces hormones that stimulate milk production after birth.
The reproductive system produces enzymes that regulate breathing during pregnancy.
The endocrine system releases hormones that trigger menstruation when fertilization does not occur.
The endocrine system produces hormones that stimulate milk production after birth.
How do the circulatory and digestive systems interact during nutrient absorption?
The circulatory system breaks down food particles.
The digestive system transports nutrients to the heart.
The circulatory system carries nutrients absorbed by the digestive system to cells.
The digestive system filters blood for impurities.
The circulatory system carries nutrients absorbed by the digestive system to cells.
When the level of carbon dioxide in the blood is too high, the excess carbon dioxide reacts with water and produces carbonic acid. The carbonic acid causes the blood pH to become more acidic. When the blood pH becomes too acidic, chemoreceptors in the brain instruct the body to react and maintain homeostasis in blood pH. Which of these responses by the body would eliminate the excess carbon dioxide and help maintain homeostasis?
Increasing the body temperature by shivering
Increasing glucose levels in the blood
Breathing more deeply and frequently
Decreasing the heart rate
Breathing more deeply and frequently
The body’s organ systems interact and work together to maintain internal balance and respond to changing needs, such as during physical activity.
Complete the sentence.
When a person touches a hot stove, the _____ system senses the heat and pain, while the _______ system provides a protective barrier that may be damaged by the burn.
Nervous
Integumentary
