- 8)After blood is “used” by cells, in other words they’ve taken the oxygen, where does it go? Select one: a. Back to the lungs for more oxygen b. Back to the heart and then on to the lungs for more oxygen c. Back to the heart to return to the body for more oxygen d. Back to the capillary beds for more oxygen e. Back to the brain, where the oxygen level is monitoredarrow_forwardWhich statement is true for the heme group present myoglobin: a. Oxygen binding to heme group is influenced by serine residues within proteins’ sequences. b. Oxygen binding to heme can become irreversible as a result of interaction with certain protein residues. c. Oxygen reversibly binds to the heme prostetic group and this binding is influenced by histidine residues within the myoglobin sequence. d. The heme group dissociates from Mb after oxygen is released.arrow_forwardGiven these characteristics:Matrix composed almost entirely of extracellular collagen fibers. It is able to withstand great pulling forces. Which of the tissue is described? A. Adipose. B.Cartilage. C.Bone. D. Dense connective tissue. E.Loose connective tissue 2. According to Frank-Starling law of the heart, A.increased preload causes increased cardiac output. B.increased afterload causes increased cardiac output. C.decreased preload causes increased afterload. D.afterload influences cardiac output more than preload. E.cardiac output is not influenced by preload.arrow_forward
- Which of these equations represents a reaction that takes place in the capillaries of muscle cells of the legs? A. HbO2 → Hb + O2 B. Hb + O2 → HbO2 C. Hb + CO → HbCO D. HbCO2 → Hb + CO2 E. None of the above answer choices correctly answers the question.arrow_forwardWhich of the following situations occurs if a person's blood becomes more alkaline? A. Hemoglobin molecules retain less oxygen per heme group under alkaline conditions than they do at neutral pH or under acidic conditions. B. Hemoglobin molecules give up oxygen more readily under alkaline conditions than they do under neutral pH or under acidic conditions. C. Hemoglobin molecules change shape and begin to lose oxygen molecules. D. Hemoglobin molecules retain oxygen more readily under alkaline conditions than they do at neutral pH or under acidic conditions. E. There is no change in hemoglobin's oxygen-binding affinity under alkaline conditions when compared to blood at neutral pH or under acidic conditions.arrow_forwardSome animals use diffusion instead of a circulatory system. Examples include: A. sponges and jellyfish B. flatworms and arthropods C. mollusks and annelids D. birds and jellyfisharrow_forward
- Descrive (in the correct order) the sequence of the blood flow through a four chambered mammalian heart. Be sure to address the following: 1. Begin with the return of oxygen poor blood from the body. 2. Describe the chemical O2/ CO2 and glucose content of the blood in the key locations. 3. Describe the machanisms that regulate the functioning of the system to maintain homeostasis.arrow_forwardSwim bladders in fish and lungs in terrestrial animals have a common evolutionary origin, but have evolved to perform different functions. What is the primary function of swim bladders in fish? They serve as buoyancy control organs. They filter toxins from the water. They allow fish to absorb most of their oxygen. They help in the digestion of food.arrow_forwardWhat are the important differences in the overall metabolic needs of a fish and a turtle and the ability of their circulatory systems to meet those needs? Select all that apply. Fish are less able to meet their metabolic needs than are turtles. Fish have a two-chamber heart (one atrium and one ventricle) and turtles have a three-chambered heart (two atria and one ventricle). Turtles are endothermic and fish are ectothermic Blood flows directly to other organs after being oxygenated in turtles, but return to the heart after being oxygenated in fish. Turtles have a double,-circuit circulatory system whereas fish have a single circulatory system.arrow_forward
- helparrow_forwardWhich of the following is NOT a way that carbon dioxide exits the body? * A. carbon dioxide travels down the concentration gradient and is able to diffuse from the tissues directly out of the body through its pores. B. carbon dioxide dissolves directly into the blood plasma to be carried to the lungs where it will be exhaled. C. Carbon dioxide binds with hemoglobin as red blood cell pass through tissues and is released as the blood cells reached the lungs. D. carbon dioxide converts into bicarbonate ions in the blood as it diffuses from the tissues and converts back to carbon dioxide as it reaches the lungs to be exhaled PLS ANSWWER ASP THANK YOUU SO MUCHarrow_forwardWhat is true about Myoglobin? A. is the oxygen-carrying molecule in most invertebrates who do not have respiratory systems. B. primary purpose is to bind to carbon monoxide to prevent us from being poisoned. C. uses copper rather than iron. D. is similar to hemoglobin but has one heme and found mostly in muscle tissue. Which animal has two atria and one ventricle with no septum?
