B
Mammals have an exoskeleton for protection.
C
Mammals possess a closed circulatory system with a four-chambered heart.
D
Mammals have a single circulatory system.
Verified step by step guidance1
Identify the key characteristics of mammalian organ systems, focusing on the circulatory system.
Understand that mammals have a closed circulatory system, which means that blood is contained within vessels and is separate from other body fluids.
Recognize that mammals have a four-chambered heart, which includes two atria and two ventricles, allowing for efficient separation of oxygenated and deoxygenated blood.
Clarify that mammals do not have an exoskeleton; instead, they have an endoskeleton made of bones and cartilage.
Note that mammals have a double circulatory system, which includes both pulmonary and systemic circuits, rather than a single circulatory system.
