A freshly minted red blood cell is released from the red bone marrow of the humerus in the right arm, and is provided with the following itinerary of tissues to visit: a) Report to the apex of the heart. b) Take a tour of the back of the left knee. c) Grab some food to go in the jejunum (middle part of the small intestine). d) Visit the right adrenal gland. List and describe all named blood vessels and pertinent structures that the red blood cell will pass through on its trip (arterioles, venules, and capillary beds can be handwaved); it is assumed to start from a small venule feeding directly to the brachial vein. Remember that the trips requires a visit through the pulmonary circuit before and after each of the four steps listed above (the apex of the heart is reached through the coronary circulation). (explain in depth please)

PATHWAYS 1. An erythrocyte travels through the heart and lungs. Starting in the inferior vena cava, list in order, all the chambers, valves and vessels through which the erythrocyte will pass on this incredible journey to the ascending aorta. 2. Starting in the radial vein, list in order, all the vessels through which an erythrocyte will pass through to reach right atrium. 3. Starting in the left ventricle, list in order, all the vessels through which an erythrocyte will pass through to reach the femoral region. Cardiovascular System

Imagine that you are a human red blood cell returning to the heart after a trip to the head. You decide to amuse yourself by drawing a basic map of your surroundings as the flow of blood carries you along. You label your starting position 1. The following sketch is your completed map, finished upon your return to position 1. (Notice that this time around, you happen to flow through the left leg rather than the head.) Although your map lacks scale and precision, it does successfully describe the path of blood flow around the body. You identify eight distinct locations on your map, labeled 1 to 8.

Imagine you are a red blood cell. You are currently moving along in the blood capillaries that connect with the tiny alveoli in the lungs. So, you've just gotten oxygenated. Map out your trip as a red blood cell: Where do you go? What do you see? Estimate how long it will take you to complete one circuit of the body before you return to the lungs.
