What are the two circuits of the cardiovascular system? What does it mean to say that the cardiovascular system is a closed syst
maksim [4K]

Answer:

The two circuits of the cardiovascular system are: Pulmonary Circuit and Systematic Circuit. The pulmonary circuit is shorter than the systemic and is responsible for carrying deoxygenated blood to the lungs from the right atrium, for oxygenation. The systemic circuit is longer and leaves the aortic artery, carrying oxygenated blood throughout the body and nutrients for survival. If less blood were pumped into the systemic circuit, this amount would not be sufficient to compensate for the organism's needs, with the corresponding consequences that this would entail.  

It is said that the cardiovascular system is a closed system because blood travels inside a network of blood vessels without leaving them.

What are the most likely question that will come in an exam​

Question Types:

  • Multiple Choice
  • True/False
  • Matching
  • Short Answer
  • Fill-in-the-blanks
  • Essays
  • Oral Exams
  • Checkboxes

Multiple choice, objective response, or MCQ (for Multiple Choice Question) is a form of an objective assessment in which respondents are asked to select only correct answers from the choices offered as a list.

True/False tests contain statements that the student marks as being either true or false. In order to qualify as true, all parts of the statement must be true. In general, true-false tests check your knowledge of facts.

A matching question is two adjacent lists of related words, phrases, pictures, or symbols. Each item in one list is paired with at least one item in the other list. Matching may be considered to be a variant of multiple-choice in which more than one choice is correct.

While opinions may differ, most teachers believe a short answer question typically requires a "short" answer. That doesn't mean an answer lacking depth analysis or information. It simply means an answer that is concise and includes just enough information to accurately and fully answer the question being asked.

Fill in the Blank questions are not opinion-based, which means that learners must be able to use the information they have mastered during the lesson to correctly answer the question. Fill in the Blank questions usually contain a sentence or paragraph featuring a blank space.

Definition of the essay question: an examination question that requires an answer in a sentence, paragraph, or short composition Examples of the essay question in a sentence.

The oral exam (also oral test or viva voce; Rigorosum in German-speaking nations) is a practice in many schools and disciplines in which an examiner poses questions to the student in spoken form. The student has to answer the question in such a way as to demonstrate sufficient knowledge of the subject to pass the exam.

A Checkboxes question lets survey takers select multiple answers from a list of choices. Use this question when you want people to be able to choose more than one answer option in the same question. Jump to...
