Animal Systems and Skeletal Structure

Name one example of an invertebrate with an exoskeleton.

• elephant

• crab

• spider

• whale

How do animals with a respiratory system obtain oxygen?

• By absorbing it through their skin

• By obtaining it from the food they eat

• By drinking it from water sources

• Through the process of breathing

What is the main function of the circulatory system in animals?

• Regulating body temperature

• Supporting the body's structure

• Producing energy for the body

• Transporting oxygen, nutrients, and hormones to cells throughout the body, as well as removing waste products

What is the role of the digestive system in animals?

• It breaks down food into nutrients for the body.

• It helps in the production of hormones.

• It regulates body temperature.

• It provides structural support for the body.

What are the main components of a vertebrate skeletal structure?

• organs, glands, and fat

• blood vessels, nerves, and skin

• bones, cartilage, and connective tissues

• muscles, tendons, and ligaments

How does the invertebrate skeletal system differ from the vertebrate skeletal structure?

• The invertebrate skeletal system is made of cartilage instead of bone.

• The invertebrate skeletal system is not involved in movement.

• The invertebrate skeletal system lacks a vertebral column.

• The invertebrate skeletal system is external rather than internal.

Explain the process of respiration in animals with a respiratory system.

• Exhale oxygen and inhale carbon dioxide

• Intake of oxygen through respiratory organs and release of carbon dioxide

• Intake of carbon dioxide and release of oxygen

• No exchange of gases in the respiratory system

What are the different types of circulatory systems found in animals?

• Respiratory circulatory system and digestive circulatory system

• Single circulatory system and double circulatory system

• Open circulatory system and closed circulatory system

• Arterial circulatory system and venous circulatory system

Describe the journey of food through the digestive system of animals.

• Consumption, metabolism, circulation, and excretion

• Intake, assimilation, distribution, and excretion

• Ingestion, digestion, absorption, and elimination

• Chewing, excretion, absorption, and elimination

What is the main difference between the circulatory system of fish and mammals?

• Fish have a single circulatory system while mammals have a double circulatory system

• Fish have a double circulatory system while mammals have a single circulatory system

• There is no difference in the circulatory system of fish and mammals

• Fish do not have a circulatory system
