How would this affect BP? Is this an example of hypertension or hypotension? Part 2: The circulatory system has 5 functions. · Highlight the statements below that are only functions of the circulatory system. It carries cells that help to fight diseases. It gives structure and support to the body. It carries waste products to the urinary system. It carries carbon dioxide from cells to the lungs. It maintains body posture. It carries nutrients from the digestive system to other cells. It carries oxygen from the lungs to other cells. · The list gives some structures in the blood and circulatory system. Heart, artery, red blood cell, ventricle, capillary, plasma, vein, white blood…
Why do interstitial fluids build up in the capillary beds of tissues? O the venous capillaries absorb more fluids than can be delivered by arterial capillaries O more fluid is usually released by arterial capillaries than is absorbed by venous capillaries O interstitial spaces lack dissolved proteins or other types of dissolved electrolytes O tissue cells within the capillary beds tend to expel fluids into nearby open spaces Next

Put the following sequence in order: _1_02 diffuses enters the blood and binds to hemoglobin in an RBC RBC enters pulmonary venule RBC crosses bicuspid/mitral valve RBC enters left ventricle, ventricle contracts RBC enters pulmonary vein RBC enters a systemic artery RBC enters a systemic arteriole RBC enters a systemic capillary Oxygen is released and diffuses across capillary into cell for aerobic respiration to occur RBC leaves pulmonary capillary RBC crosses aortic valve RBC enters aorta RBC enters left atrium, atrium contracts
Describe the path a red blood cell takes in the human circulatory system using the following anatomical structures: right and left atrium, right and left ventricle, pulmonary and aortic semilunar valve, inferior and superior vena cava, pulmonary artery and aorta, right AV valve (tricuspid valve) and left AV valve (mitral or bicuspid valve), and pulmonary veins.
All are characteristics of erythrocytes (red blood cells) EXCEPT: -makes up large percentage of total blood cells -integral to inflammatory and immune responses -high surface area to volume ratio due to biconcave disk shape -lacking a nucleus or mitochondria -involved with carrying oxygen to body cells

Blood clotting is one of nature's most elegant creations, but it sometimes goes awry. Use your knowledge of different types of blood cells and the chemical aspects of the clotting process to answer the following: 1. After getting his blood cell count, Josh was informed that his platelet count was low. What is a typical platelet count? How would Josh's low platelet count impact his hemostasis after getting a cut on his forearm? (Be very specific) 2. Briefly explain the different roles of the three stages of the intrinsic blood clotting pathway 3. Explain how any event that prevents plasminogen from becoming fully activated would lead to a thromboembolic disorder. Identify all the chemicals that directly activate plasminogen. 4. Identify the two most common types of the genetic disorder called hemophilia. Explain how each of two types of hemophilia result in impaired hemostasis. 5. Explain how the endocrine system contributes to the homeostasis of blood oxygen levels.
