You will list a total of THREE blood pathways to answer this question: Pathways 1 and 2 (3.5 pts) Trace the two unique paths a drop of blood could take from the left ventricle of the heart to the LEFT occipital lobe of the cerebrum. Remember to specify right/left (when necessary) and artery/vein for all vessels you use in your pathway. This is NOT just a matter of using the same pathway on the right and left sides of the body. Rather, each of these paths MUST use different blood vessels to ascend through the cervical region and enter the cranial cavity. Pathway 3 (1.75 pt) Trace the path a drop of blood would take to get from the LEFT frontal lobe of the cerebrum back to the right atrium of the heart Be sure to indicate right or left when naming blood vessels that are paired!

The layer of a blood vessel wall that contains the smooth muscle that is responsible for changing the diameter of the lumen of the vessel is called the ___________

The electrical event (action potential) that begins each heartbeat and sets the basic heart rate occurs at a region in the wall of the right atrium known as the ________________.

Hemoglobin is a protein that is usually found dissolved in blood plasma, and it is responsible for binding and transporting oxygen in the blood.

Lymph from the left side of the body flows through the ________ immediately before draining into the venous system at the junction of the left internal jugular vein and left subclavian vein.

The lymphatic vessels are an important part of the cardiovascular system.

Capillaries in the liver and the spleen have large lumens and follow twisting paths through these organs. These capillaries also have large holes in their walls that allow large particles (such as blood cells) to exit the capillaries. What is the correct name for this type of capillary?
