Human Biology: Body Organization and Homeostasis

Since sugar comes from food, which system would directly affect blood sugar levels? respiratory muscular skeletal digestive

digestive

After running, Ollie's blood pressure was high. His nervous system sensed this and sent a message to decrease heart rate and blood flow. Which system worked together with the nervous system? skeletal system circulatory system respiratory system digestive system

circulatory system

The hairs on Xander's arms just started lying flat against his skin. Which is most likely his internal body temperature? 35°C 36°C 37.5°C 38.5°C

38.5°C

Which best explains how the body maintains homeostasis? All systems work together to stabilize the body. Each system works independently to stabilize the body. All systems work together to match the external environment. Each system works independently to match the external environment.

All systems work together to stabilize the body.

___ is the state of maintaining a stable internal environment despite changing external conditions.

Homeostasis

(Essay) What would happen if organ systems failed to work together?

If the organ systems do not work together, then homeostasis is not maintained. If homeostasis is not maintained, the cells of the body will not work properly. As a result, the body will not work properly.

Which explains how the nervous system is typically involved in keeping the body in homeostasis? - It processes the environment and sends out signals. - It controls movement and provides structure. - It physically breaks down and absorbs food. - It puts oxygen in the blood, which is essential for life.

It processes the environment and sends out signals.

_____, amount of sugar, and amount of water are some conditions that need to be right in the body for cells to work properly. When all the conditions are just right, the cells function properly.

Temperature

(Essay) Explain how the organ systems work together to warm up the body on a cold day.

The brain, through the nervous system, sends signals to the muscular system, causing the muscles to move rapidly. This rapid motion produces heat in the body and is observed as shivering. The brain also sends signals to the muscles right beneath the skin. These muscles shorten and tighten, causing the hairs on the skin to stand up. When the hairs stand up, heat is kept in the air trapped within the hairs, which keeps the body warm.

Lewis is running in a race. His muscles need oxygen. Which best describes how multiple systems interact to bring him into homeostasis? The circulatory stem brings oxygen to the respiratory system, which delivers oxygen to the muscular system. The respiratory system brings oxygen to the circulatory system, which delivers oxygen to the muscular system. The respiratory system brings oxygen to the circulatory system, which delivers oxygen to the skeletal system. The circulatory system brings oxygen to the respiratory system, which delivers oxygen to the skeletal system.

The respiratory system brings oxygen to the circulatory system, which delivers oxygen to the muscular system.

The lungs, nose, and trachea are organs of the respiratory system. Which best describes these organs? They deliver nutrients to the other tissues. They deliver oxygen to the blood. They are both used for support. They help break down food.

They deliver oxygen to the blood.

After the body has begun shivering, what explains why it would stop shivering? When body temperature returns to normal, the respiratory system sends a message to the skeletal system to stop shaking. When body temperature returns to normal, the nervous system sends a message to the muscular system to stop shaking. While body temperature is below normal, the nervous system sends a message to the skeletal system to stop shaking. While body temperature is below normal, the respiratory system sends a message to the muscular system to stop shaking.

When body temperature returns to normal, the nervous system sends a message to the muscular system to stop shaking.

Which levels need to be correct for cells to function? Select four options. blood sugar body height body water body temperature blood oxygen

blood sugar body water body temperature blood oxygen

Which is an example of how the body maintains homeostasis? - by increasing thirst when cells are low on water - by decreasing thirst when cells are low on water - by shivering when it is hot - by sweating when it is cold

by increasing thirst when cells are low on water

Geneva was walking on the beach on a crisp November morning when a cool wind came her way. How would Geneva's body respond to maintain homeostasis? by sweating by shivering by keeping hair on skin flat

by shivering

Which is an organ? heart circulatory system blood muscle tissue

The human body works well when the cells of the body work well. The cells in the body work well when the conditions are just "right." These "right" conditions are maintained by the body through _____, the state of maintaining a stable internal environment despite changing external conditions.
