Mid-Unit Test (Circulatory System)

Question 1: What do the terms systemic and pulmonary mean? Define each term.

What is the septum and what is its function?

________is the period of contraction of the ventricles of the heart that occurs between the first and second heart sounds of the cardiac cycle (the sequence of events in a single heartbeat). Systole causes the ejection of blood into the aorta and pulmonary trunk.

________represents when the blood vessels return blood to the heart in preparation for the next ventricular contraction. Systole begins when the mitral valve (or tricuspid) closes and concludes with the closure of the aortic valve (or pulmonic).

• Diastole

• Systole

• Lunar artery

• Aneurysm

Question 2: What is the Aorta?

A)Answer the question by identifying if its a vein or an artery?

B) What are each of these blood vessels connected to?

              C) What type of blood do they carry?

Question 3: The Pulmonary Veins

A)What are each of these blood vessels connected to?

              C) What type of blood do they carry?
