Unit 7 Test Review EHC Sem 1 🎉

Elijah, Aria, and James are having a debate. They are trying to figure out what the majority of our blood consists of. Can you help them out?

• red blood cells

• white blood cells

• plasma

• solutes

Imagine this! Our friend Mia is a super scientist working on a secret project. She discovered a superhero, let's call him James, who has hemophilia and is unable to properly clot. This suggests a problem in James' :

• white blood cells

• red blood cells

• plasma proteins

• myoglobulins

Hannah, Anika, and Michael are playing a trivia game. They got a question: 'Which system in our body is responsible for forming new red blood cells?'

• Is it the digestive system?

• Could it be the integumentary system?

• Maybe it's the skeletal system?

• Or is it the nervous system?

Arjun, Evelyn, and Ethan are having a debate about the lifespan of red blood cells. Arjun thinks it's about four hours, Evelyn believes it's about four days, and Ethan is convinced it's about four weeks. Who is correct?

• Arjun - about four hours

• Evelyn - about four days

• Ethan - about four weeks

• None of them

During a biology class, Aria, Emma, and Daniel were discussing the role of erythrocytes. They are a fundamental part of:

• how your body digests food

• how your body fights off infections

• how your respiratory system supplies your body

• how your nervous system sends signals to your body

Emma, Daniel, and Benjamin are discussing the spleen. They're trying to figure out its function. Can you help them out? Your spleen:

Samuel, Ethan, and William are studying for their biology exam. They are discussing leukocytes, a type of white blood cell. Samuel asks, 'Which type of leukocyte has, by far, the longest potential life span?'

• basophils

• eosinophils

• lymphocytes

• neutrophils
